An embodiment of the disclosure relates to an electronic device, for example, an electronic device including a transmission line using a microstrip line.
Typically, an electronic device may mean a device that performs a specific function according to a program provided therein (e.g., an electronic scheduler, a portable multimedia reproducer, a mobile communication terminal, a tablet PC, an image/sound device, a desktop/laptop PC, or a vehicle navigation system), as well as a home appliance. For example, these electronic devices may output information stored therein as sound or image. With the increase of degree of integration of electronic devices and the generalization of ultra-high-speed or high-capacity wireless communication, recently, a single electronic device, such as a mobile communication terminal, may be provided with various functions. For example, various functions, such as an entertainment function such as a game, a multimedia function such as music/video playback, or a communication and security function for mobile banking or the like, and/or a schedule management or e-wallet function, are integrated in a single electronic device, in addition to a communication function. As the degree of integration of electronic devices increases, portability is further improved, leading to the commercialization of wearable electronic devices such as wristwatch-type or eyeglass-type electronic devices, which may make the electronic devices more convenient to carry and use.
The above-described information may be provided as background for the purpose of helping understanding of the disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art with respect to the disclosure.
According to an embodiment, an electronic device includes a housing, a circuit board accommodated inside the housing, a first plate disposed inside the housing to at least partially face the circuit board, a transmission line disposed on one (hereinafter, “first surface”) of opposite surfaces of the first plate and electrically connected to the circuit board, a ground conductor disposed on another one (hereinafter “second surface”) of the opposite surfaces of the first plate and electrically connected to the circuit board, and a radiation conductor pattern disposed on one of the first surface and the second surface and electrically connected to one end of the transmission line. The transmission line is disposed to at least partially overlap the ground conductor when viewed from one of the first surface and second surface, and the transmission line is configured to transmit a wireless communication signal transmitted or received via the radiation conductor pattern.
The above-described aspects or other aspects, configurations, and/or advantages regarding an embodiment of the disclosure may become more apparent through the following detailed description made with reference to the accompanying drawings.
Throughout the appended drawings, like reference numerals may be assigned to like parts, components, and/or structures.
As the use of portable electronic devices such as mobile communication terminals or tablet personal computers (PCs) has become commonplace, competition for downsizing and weight reduction of electronic devices is intensifying. For example, as an electronic device has a narrowed inner space, the degree of freedom in design may be lowered in the arrangement of various electrical/electronic components or in implementing an antenna structure (e.g., a radiation conductor and/or a transmission line between the radiation conductor and a communication circuit).
An embodiment of the disclosure may provide an electronic device improved in the degree of freedom in design in the arrangement of an antenna structure by using a microstrip transmission line.
An embodiment of the disclosure may provide an electronic device including a transmission line provided with a stable operating environment while being easily arranged in a narrow inner space.
The technical problems to be addressed by this disclosure are not limited to those described above, and other technical problems, which are not described above, may be clearly understood by a person ordinarily skilled in the related art, to which this disclosure belongs.
According to an embodiment of the disclosure, by arranging a transmission line and/or a radiation conductor pattern using a microstrip on a plate disposed inside a housing, it may be easy to implement or arrange an antenna structure even in a narrow space. In an embodiment, since it is possible to form a transmission line (or a radiation conductor pattern) on a plate through a printing, plating, deposition, or laser direct structuring (LDS) process, the degree of freedom in design may be improved in the shape or position of the transmission line (or the radiation conductor pattern). In an embodiment, by arranging a ground conductor corresponding to a transmission line on a plate, a stable transmission environment of a feed signal may be provided.
Effects that are capable of being obtained by the embodiment(s) of the disclosure are not limited to those described above, and other effects not described above may be clearly understood by a person ordinarily skilled in the art to which the disclosure belongs based on the following description.
The following description made with reference to the appended drawings may provide an understanding of various exemplary implementations of the disclosure, including the claims and their equivalents. An exemplary embodiment disclosed in the following descriptions includes various specific details to help understanding, but is considered to be one of various exemplary embodiments. Accordingly, it will be apparent to those skilled in the art that various changes and modifications of the various implementations described herein can be made without departing from the scope of the disclosure. In addition, descriptions of well-known functions and configurations may be omitted for clarity and brevity.
The terms and words used in the following description and claims are not limited to a bibliographical meaning, but may be used to describe an embodiment of the disclosure clearly and consistently. Therefore, it will be obvious to those skilled in the art that the following description of various implementations of the disclosure is provided for the purpose of explanation, not for the purpose of limiting the disclosure defined as the scope of rights and equivalents thereto.
It should be understood that the singular forms of “a,” “an,” and “the” contain the meaning of “plural,” unless the context clearly indicates otherwise. Thus, for example, “a component surface” may be understood to include one or more of the surfaces of a component.
The electronic device according to an embodiment of the disclosure may be one of various types of electronic devices. The electronic devices may include, for example, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. According to an embodiment of the disclosure, the electronic devices are not limited to those described above.
It should be appreciated that an embodiment of the disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used in the disclosure, each of such phrases as “A or B”, “at least one of A and B”, “at least one of A or B”, “A, B, or C”, “at least one of A, B, and C”, and “at least one of A, B, or C”, may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd”, or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with”, “coupled to”, “connected with”, or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
As used in connection with an embodiment of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic”, “logic block”, “part”, or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
An embodiment of the disclosure may be implemented as software (e.g., the program) including one or more instructions that are stored in a storage medium (e.g., internal memory or external memory) that is readable by a machine (e.g., the electronic device). For example, a processor (e.g., the processor) of the machine (e.g., the electronic device) may invoke at least one of the one or more instructions stored in the storage medium, and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
A method according to an embodiment of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
According to an embodiment, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in different components. According to an embodiment, one or more of the above-described components or operations may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to an embodiment, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
In the following detailed description, a length direction, a width direction, and/or a thickness direction of an electronic device may be referred to, wherein the length direction may be defined as the “Y-axis direction”, the width direction may be defined as the “X-axis direction”, and/or the thickness direction may be defined as the “Z-axis direction.” In an embodiment, “negative/positive (−/+)” may be referred to together with the Cartesian coordinate system illustrated in the drawings regarding the directions in which components are oriented. For example, the front surface of an electronic device or a housing may be defined as a “surface facing the +Z direction,” and the rear surface may be defined as a “surface facing the −Z direction.” In an embodiment, a side surface of the electronic device and/or the housing may include an area facing the +X direction, an area facing the +Y direction, an area facing the −X direction, or an area facing the −Y direction. In an embodiment, the “X-axis direction” may include both the “−X direction” and the “+X direction.” It is noted that these are based on the Cartesian coordinate system described in the drawings for the sake of brevity of description, and the descriptions of these directions or components do not limit various embodiments of the disclosure. For example, the direction the front surface or the rear surface faces may vary depending on a state in which the electronic device is placed on a flat surface, or a relative alignment state of housings when the electronic device includes a plurality of housings, and the above-mentioned directions may be differently understood according to a user's gripping habit.

In an embodiment, the ground conductor 355 may include a conductor pattern having a line width (e.g., the second line width W2 in
According to an embodiment, the electronic device 300 may further include a radiation conductor pattern 353 disposed, more preferably directly disposed on at least one surface of the first plate 360b (e.g., the second surface F2 facing the +Z direction and/or the first surface F1 facing the −Z direction). The radiation conductor pattern 353 is a conductive pattern provided through, for example, printing, plating, deposition, and/or laser direct structuring, and may function as an antenna. According to an embodiment, the transmission line 351 may transmit wireless communication signals transmitted and/or received through the radiation conductor pattern 353 between the circuit board 340 and the radiation conductor pattern 353. In an embodiment, a portion of one conductor pattern (e.g., a laser direct structured pattern) may be provided as the transmission line 351, and another portion may be provided as the radiation conductor pattern 353. For example, in the ground conductor 355 of one conductor pattern located on one surface of the first plate 360b, the portion disposed to overlap the ground conductor 355 may function as a transmission line 351, and in the one ground conductor, the portion disposed not to overlap the ground conductor 355 may function as the radiation conductor pattern 353 (e.g., an antenna). In an embodiment, regardless of whether the transmission line 351 and the radiation conductor pattern 353 overlap the ground conductor 355, the transmission line 351 and the radiation conductor pattern 353 may be distinguished from each other by having different widths while being provided in one conductor pattern.

For example, after the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353 are arranged, an additional injection-molded product, a synthetic resin sheet, a film or a coating layer is disposed on the surface of the first plate 360b to cover the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353. In an embodiment, even if covered by an additional layer, among the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353, at least the radiation conductor pattern 353 may provide an environment capable of radiating a wireless signal to the first plate 360b and/or the outer space of the electronic device 300.

The signal terminal S and/or the ground terminal(s) G1 and G2 may be located on one (e.g., the second surface F2) of the opposite surfaces of the first plate 360b that faces the circuit board 340. In an embodiment, the signal terminal S may be electrically connected, more preferably directly electrically connected to the transmission line 351, and may be electrically connected to the circuit board 340 via a contact member 345 such as a C clip. The first ground terminal G1 may be electrically connected, more preferably directly electrically connected to the ground conductor 355, and may be electrically connected to the circuit board 340 via the contact member 345. For example, a plurality of contact members 345 may be disposed, more preferably directly disposed on the circuit board 340, and when the circuit board 340 and the first plate 360b are accommodated in the housing 201, the contact members 345 may each come into contact with one of the signal terminal S and the first ground terminal G1. As described above, the transmission line 351 and/or the signal terminal S may be electrically connected to the circuit board 340 (e.g., a communication module) via one of the contact members 345, and the ground conductor 355 and/or the first ground terminal G1 may be electrically connected to the circuit board 340 (e.g., a ground plane) via another one of the contact members 345.
In an embodiment, the second ground terminal G2 may be electrically connected, more preferably directly electrically connected to the ground conductor 355, and may electrically connect the ground conductor 355 to another structure within the housing 201.

The wiring recesses 361a and 361b may be, for example, areas or spaces recessed from the surface of the first plate 360b. In an embodiment, when the wiring recesses 361a and 361b are provided on one of the opposite surfaces of the first plate 360b, one of the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353 may be at least partially provided in the wiring recesses 361a and 361b. The conductive pattern(s) constituting the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353 may be at least partially disposed in the wiring recesses 361a and 361b. In an embodiment, when a first wiring recess 361a may be provided in a first one F1 of opposite surfaces of the first plate 360b and a second wiring recess 361a may be provided in a second one F2 of the opposite surfaces of the first plate 360b, each of the transmission line 351 (and/or the radiation conductor pattern 353) and the ground conductor 355 may be disposed in one the first wiring recess 361a or the second wiring recess 361b. By being accommodated into one of the wiring recesses 361a and 361b, the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353 may not substantially protrude from the surface of the first plate 360b. For example, the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353 may be protected from damage caused by interference with another structure outside the first plate 360b.
According to an embodiment, the transmission line 351 is a conductive pattern extending in one direction (e.g., the X-axis direction) and may have a first line width W1. The ground conductor 355 is another conductive pattern extending substantially in parallel to the transmission line 351 and may at least partially have a second line width W2 different from the first line width W1. In an embodiment, the ground conductor 355 may have the second line width W2 substantially greater than the first line width W1. In an embodiment, the line width (e.g., the first line width W1) of the transmission line 351 may be determined by the thickness h or permittivity of the first plate 360b. For example, when the thickness h of the first plate 360b having a permittivity of about 3 to about 5 is about 0.5 mm, the first line width W1 of the transmission line 351 may be about 0.86 mm to about 1.24 mm. In an embodiment, when the thickness h of the first plate 360b having a permittivity of about 3 to about 5 is about 0.8 mm, the first line width W1 of the transmission line 351 may be about 1.34 mm to about 2.0 mm. The material (e.g., the permittivity) and thickness h of the first plate 360b and/or the first line width W1 of the transmission line 351 may be designed variously depending on the specifications of the electronic device 300 to be actually manufactured.
According to an embodiment, the electronic device 300 may further include a radiation conductor pattern 353. In an embodiment, the radiation conductor pattern 353 may transmit, through the transmission line 351, a wireless communication signal received to the circuit board 340, or may receive a wireless communication signal to be transmitted through the transmission line 351. For example, on the first plate 360b, the radiation conductor pattern 353 may be disposed on the same surface as the transmission line 351 or disposed on a surface different from that for the transmission line 351, and may be provided with a power supply signal to transmit and/or receive a wireless signal. In this embodiment, the configuration of the radiation conductor pattern 353 disposed on the first plate 360b is exemplified, but it is noted that the embodiment(s) of the disclosure is (are) not limited thereto. For example, a portion of the housing 201 of
According to an embodiment, the radiation conductor pattern 353 may extend along a predetermined trajectory, and may be a conductive pattern substantially extending from the transmission line 351 when provided on the first plate 360b. For example, when provided on the same surface of the first plate 360b, the transmission line 351 and the radiation conductor pattern 353 may be different portions in substantially one conductive pattern. In an embodiment, in the structure in which the transmission line 351 and the radiation conductor pattern 353 are provided as one conductive pattern, the transmission line 351 may be disposed to overlap the ground conductor 355 and the radiation conductor pattern 353 may be provided not to overlap the ground conductor 355 when viewed from one of the opposite surfaces of the first plate 360b. For example, when viewed in the Z-axis direction, the conductive pattern of the portion overlapping the ground conductor 355 may function as the transmission line 351, and the conductive pattern of the portion, which does not overlap the ground conductor 355, may function as the radiation conductor pattern 353.
According to an embodiment, the transmission line 351 and the radiation conductor pattern 353 may have different line widths. For example, the radiation conductor pattern 353 may have a third line width A1 different from the first line width W1. In an embodiment, when the first line width W1 and the third line width A1 are different from each other or depending on the relative alignment state of the transmission line 351 and the radiation conductor pattern 353, the electronic device 300 may further include a matching line 359 disposed, more preferably directly disposed between the transmission line 351 and the radiation conductor pattern 353. For example, the matching line 359 may have the first line width W1 at a point connected to the transmission line 351, and may have a line width that gradually increases or decreases in a direction away from the transmission line 351. For example, the matching line 359 may have a shape capable of suppressing connection loss or reflection loss at the connection point between the transmission line 351 and the radiation conductor pattern 353. In an embodiment, in the structure in which the transmission line 351 and the radiation conductor pattern 353 are aligned in a direction in which the transmission line 351 and the radiation conductor pattern 353 cross each other, the matching line 359 may have a line width that may gradually increases in a direction away from one end of the transmission line 351. The line width of the matching line 359 at the point where the matching line 359 is in contact with the radiation conductor pattern 355 may be greater than the line width at the point where the matching line 359 is in contact with the transmission line 351.

For example, the embodiment(s) of the disclosure may include a structure in which the transmission line 351 and the ground conductor 355 are disposed respectively on different surfaces of the first plate 360b, and it is noted that the transmission line 351, the ground conductor 355, and/or the radiation conductor pattern 353 are not limited to the aforementioned embodiment(s).
