The disclosure relates to electronic devices with an antenna device.
Developing electronic information communication technology integrates various functionalities into a single electronic device. For example, smartphones pack the functionalities of a sound player, imaging device, and scheduler, as well as the communication functionality and, on top of that, may implement more various functions by having applications installed thereon.
The user of an electronic device may search, screen, and obtain more information by accessing a network, but rather than simply using the functionalities or information (e.g., applications) of the electronic device. Direct access to the network (e.g., wired communication) may enable quick and stable communication establishment but its usability may be limited to a fixed location or space. Wireless network access is less limited in location or space, delivers such a level of speed and stability as approaches those of direct network access, and is expected to be able to establish communication faster and more stable than direct network access.
As smartphones or other personal/portable communication devices spread, users' demand for portability and use convenience is on the rise. For example, foldable or rollable electronic devices may be easy to carry and deliver an enhanced multimedia environment, with their larger screen.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
It may be hard to secure communication environments in different frequency bands in a compact electronic device. For example, an independent operation environment (e.g., a sufficient space) needs to be provided for each antenna, but this may be impossible to attain in such a small electronic device. Foldable or rollable electronic devices have a further shrunken structure or space for placing antennas. The housing is thinned down for more flexibility and thus fails to provide a space large enough to arrange antennas. In an embodiment, a foldable or rollable electronic device may experience a change in the operation environment of the antenna when rolled or folded. For example, the arrangement of structures around the antenna may be altered in the folded or rolled state, and so is the operation performance of the antenna.
Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device with an antenna device, which delivers a stable operation performance even when the structures are folded or rolled.
Another aspect of the disclosure is to provide an electronic device with an antenna device, which may be easily equipped in a slim, compact structure and deliver a stable operation performance.
Another aspect of the disclosure is to provide an electronic device with a plurality of first and second connection members for electrical connection between a switching unit and each radiation conductor (e.g., antennas) arranged in structures.
Another aspect of the disclosure is to provide an electronic device with an antenna device, which delivers a stable operation performance according to a hand grip on the structures in the folded or unfolded state of the structures.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

As another example, the radiation conductor may implement at least part of the first and second side surface member as an antenna, enabling easier placement even in a slim, compact structure.
According to various embodiments, in the unfolded state or folded state of the first and second housing structures in the plurality of housings and hinge structure supporting one display, a plurality of first and second connection members (e.g., coaxial cables, flexible printed circuit boards (FPCBs), micro strip lines, or strip lines) for connecting at least one first to fourth radiation conductor and a switching unit included in the electronic device are formed, providing a better electrical connection between the switching unit and the at least one first to fourth radiation conductor and hence enhancing the antenna function of the at least one first to fourth radiation conductor.
According to various embodiments, in the folded state or unfolded state of the first and second housing structures, switching among the first to fourth radiation conductors may be rendered according to the hand grip of the first and second housing structures, enabling stable transmission/reception and resultantly allowing the antenna device stable radiation performance.

Referring to
According to an embodiment, the pair of housing structures 210 and 220 may include a first housing structure 210 with a sensor area 231d, a second housing structure 220, a first back cover 240, and a second back cover 250. The pair of housing structures 210 and 220 of the electronic device 200 are not limited to the shape and coupling shown in
According to an embodiment, the first housing structure 210 and the second housing structure 220 may be positioned on opposite sides of a first axis, e.g., a folding axis A, and they may be overall symmetrical in shape with each other with respect to the folding axis A. According to an embodiment, the first housing structure 210 and the second housing structure 220 may be rotated on the hinge structure 264 or hinge cover 265 with respect to different folding axes. For example, the first housing structure 210 and the second housing structure 220 each may be rotatably coupled to the hinge structure 264 or the hinge cover 265, and the first housing structure 210 and the second housing structure 220 may be rotated on the folding axis A or different folding axes from the position where they are folded together to the position where they are inclined or positioned side-by-side with respect to each other.
As used herein, when A and B are positioned or extend side-by-side, it may mean that A and B are positioned at least partially next to each other or at least partially in parallel with each other. According to an embodiment, when A and B are disposed (or arranged) side-by-side, it may mean that A and B are disposed (or arranged) to face in the same direction or directions parallel with each other. In the following description, although the example phrases “side-by-side” and “in parallel with each other” may be used to describe the corresponding structures, the shape or arrangement of the structures may easily be appreciated from the accompanying drawings.
According to an embodiment, the first housing structure 210 and the second housing structure 220 may form different angles or distances depending on whether the electronic device 200 is in an unfolded state (or flat state, or open state) or folded state (or folding state), or in a state therebetween. According to an embodiment, the first housing structure 210 and the second housing structure 220 may be symmetrical in shape except that the first housing structure 210 further includes a sensor area 231d where various sensors are arranged. Alternatively, the sensor area 231d may be disposed in at least a portion of the second housing structure 220, not the first housing structure 210, or another sensor area may be included in the second housing structure 220.
According to an embodiment, in the unfolded state of the electronic device 200, the first housing structure 210 may be connected to the hinge structure (e.g., the hinge structure 264 of
According to an embodiment, the second housing structure 220 may be connected to the hinge structure (e.g., the hinge structure 264 of
According to an embodiment, the electronic device 200 may include a recess 201 to receive the display 230 via a structural shape combination of the first housing structure 210 and the second housing structure 220. The recess 201 may have substantially the same size as the display 230. According to an embodiment, due to the sensor area 231d, the recess 201 may have two or more different widths in the direction perpendicular to the folding axis A. For example, the recess 201 may have a first width W1 between a first portion 220a, parallel with the folding axis A, of the second housing structure 220, and a first portion 210a, formed at an edge of the sensor area 231d, of the first housing structure 210 and a second width W2 formed by a second portion 220b of the second housing structure 210 and a second portion 210b, which is parallel with the folding axis A and does not correspond to the sensor area 231d, of the first housing structure 210. In this case, the second width W2 may be larger than the first width W1. For example, the recess 201 may be formed with the first width W1 between the first portion 210a of the first housing structure 210 and the first portion 220a of the second housing structure 220, which are asymmetrical in shape with each other, and the second width W1 between the second portion 210b of the first housing structure 210 and the second portion 220b of the second housing structure 220, which are symmetrical in shape with each other. According to an embodiment, the first portion 210a and second portion 210b of the first housing structure 210 may be formed to have different distances from the folding axis A. The width of the recess 201 is not limited thereto. According to an embodiment, the recess 201 may have two or more different widths depending on the shape of the sensor area 231d or the asymmetrical shape portions of the first housing structure 210 and the second housing structure 220.
According to an embodiment, the first housing structure 210 and the second housing structure 220 may at least partially be formed of a metal or non-metallic material with a rigidity selected to support the display 230. According to an embodiment, the first housing structure 210 and the second housing structure 220 may at least partially include an electrically conductive material.

The grip sensor may detect holding or gripping the electronic device 200 in an external object (e.g., the user's hand) The grip sensor may be disposed in at least one of the left/right side surfaces, top/bottom surfaces, or back surface of the first and second housing structures 210 and 220 of the electronic device 200. The grip sensor may transfer the obtained sensor information to the processor 1400.
According to an embodiment, if the user's body touches the electronic device 200, the grip sensor may detect a variation in capacitance of the electronic device 200, thereby sensing the user's body touch. Thus, the grip sensor, as a separate sensor for detecting the user's body touch, may be mounted in the electronic device 200, or the grip sensor, as a non-separate sensor, may be implemented to detect variations in capacitance of the first and second housing structures 210 and 220 (e.g., a metal housing) of the electronic device 200.
According to an embodiment, such a grip sensor is described as an example.
For example, in the plurality of housing structures 210 and 220 and hinge structure 264 supporting one display (e.g., the display 230 of

The memory 1401 may store a switch control program for controlling the switching unit 1300. For example, the switch control program may store data to control the switching unit 1300 to switch the at least one first to fourth radiation conductor 1001, 1002, 1003, and 1004. For example, the switch control program may store data for adjustment to switch from the at least one first or second radiation conductor 1001 or 1002 to the at least one third or fourth radiation conductor 1003 or 1004 or from the at least one third or fourth radiation conductor 1003 or 1004 to the at least one first or second radiation conductor 1001 or 1002 depending on the hand grip on the first and second housing structures 210 and 220.
When the first housing structure 210 is hand-gripped in the unfolded state of the first housing structure 210 and the second housing structure 220, the processor 1400 may detect the hand grip via the sensor unit 1100 and control the switching unit 1300 to switch from the at least one first or second radiation conductor 1001 or 1002 of the first housing structure 210 to the at least one third or fourth radiation conductor 1003 or 1004 of the second housing structure 220. In this case, the at least one first or second radiation conductor 1001 or 1002 of the first housing structure 210 may experience a lowering in radiation performance due to the user's hand grip. However, since the at least one third or fourth radiation conductor 1003 or 1004 of the second housing structure 220 is not in the user's hand grip, the at least one third or fourth radiation conductor 1003 or 1004 may be prevented from a lowering in radiation performance due to influence by the human body. Thus, the electronic device 200 may select the at least one third or fourth radiation conductor 1003 or 1004 by the switching unit 1300 and use it as an antenna.
