This application claims priority under 35 U.S.C. § 119(a) to Korean Patent Application Serial No. 10-2016-0113682, which was filed in the Korean Intellectual Property Office on Sep. 5, 2016, the entire content of which is incorporated herein by reference.
The present disclosure relates to an electronic device capable of transmitting/receiving a signal through an antenna.
The use of a wearable electronic device is increasing as electronic device technology progresses. The wearable electronic device may include a communication function to perform various functions such as voice call, message confirmation, wireless payment, and the like.
The wearable electronic device may be manufactured with a small size so it can be easily mounted on a portion of the user's body, for example, a wrist. The wearable electronic device may have an insufficient space to mount an antenna. If the metallic parts are disposed adjacent to the antenna due to the insufficient space, the performance of the antenna may be reduced. For example, a signal may be induced at a metal component, thereby reducing reception efficiency of the antenna.

In accordance with an aspect of the present disclosure, an electronic device includes a housing that includes a first conductive member disposed on a first surface facing a first direction and a second conductive member disposed adjacent to a second surface facing a second direction opposite to the first direction, a nonconductive member that is located between the first conductive member and the second conductive member and forms part of the housing, a printed circuit board (PCB), a communication circuit that is disposed on the PCB and is electrically connected with the first conductive member and the second conductive member, and a ground part that is electrically connected with at least one of the first conductive member and the second conductive member. The communication circuit feeds the first conductive member and the second conductive member and transmits/receives a signal through the first conductive member and the second conductive member.
In accordance with another aspect of the present disclosure, an electronic device includes a housing that includes a first conductive member disposed on a first surface facing a first direction, a second conductive member disposed adjacent to a second surface facing a second direction opposite to the first direction, and a nonconductive member located between the first conductive member and the second conductive member, a printed circuit board (PCB), a communication circuit that is disposed on the PCB and is electrically connected with the first conductive member, a ground part electrically connected with the first conductive member, and an antenna radiator that is disposed on the nonconductive member and is electrically connected with the communication circuit and the ground part. The communication circuit feeds the first conductive member to transmit/receive a signal in a first frequency band and feeds the antenna radiator to transmit/receive a signal in a second frequency band.
In accordance with another aspect of the present disclosure, an electronic device includes a housing that includes a conductive member disposed on a first surface facing a first direction and a ground part connected with the conductive member and disposed adjacent to a second surface facing a second direction opposite to the first direction, a printed circuit board (PCB), and a communication circuit that is disposed on the PCB and is electrically connected with the conductive member. The communication circuit feeds a first point of the conductive member, the conductive member is selectively connected with the ground part at a second point and a third point, and the communication circuit transmits/receives a signal in a first frequency band by an electrical path formed through the first point and the second point and transmits/receives a signal in a second frequency band by an electrical path formed through the first point and the third point.
The above and other aspects, features, and advantages of certain embodiments of the present disclosure will be more apparent from the following description taken in conjunction with the accompanying drawings, in which:
Throughout the drawings, it should be noted that like reference numbers are used to depict the same or similar elements, features, and structures.
Hereinafter, various embodiments of the present disclosure are described with reference to accompanying drawings. Accordingly, those of ordinary skill in the art will recognize that modifications, equivalents, and/or alternatives of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure.
In this disclosure, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate the existence of corresponding features (e.g., elements such as numeric values, functions, operations, or components) but do not exclude the presence of additional features.
In this disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included.
The terms, such as “first”, “second”, and the like used in this disclosure may be used to refer to various elements regardless of the order and/or the priority and to distinguish the relevant elements from other elements, but do not limit the elements. For example, “a first user device” and “a second user device” indicate different user devices regardless of the order or priority. For example, without departing the scope of the present disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.
It will be understood that when an element (e.g., a first element) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element), it may be directly coupled with/to or connected to the other element or an intervening element (e.g., a third element) may be present. In contrast, when an element (e.g., a first element) is referred to as being “directly coupled with/to” or “directly connected to” another element (e.g., a second element), it should be understood that there are no intervening element (e.g., a third element).
According to the situation, the expression “configured to” used in this disclosure may be interchangeably used with the expressions “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”. The term “configured to” does not mean only “specifically designed to” in hardware. Instead, the expression “a device configured to” may mean that the device is “capable of” operating together with another device or other components. For example, a “processor configured to (or set to) perform A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor (AP)) which performs corresponding operations by executing one or more software programs which are stored in a memory device.
Terms used in this disclosure are used to describe specified embodiments and are not intended to limit the scope of another embodiment. The terms of a singular form may include plural forms unless otherwise specified.
