     At least a portion of a housing (e.g., lateral member) used as the antenna should be spaced apart from a conductive plate (e.g., bracket or support member) inside the electronic device at a predetermined distance to secure a performance of the antenna. 
     End surfaces between at least a portion of the housing and the conductive plate may be formed in a symmetrical structure, and as a distance between the end surfaces reduces, a radiation loss may increase. 
     In order to secure an antenna performance of the electronic device, in the case that a plurality of segment parts are formed in the housing, the electronic device may be vulnerable to an external impact. 
     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 that maintains a radiation performance of an antenna and maintains rigidity of a housing. 
     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. 
     In accordance with an aspect of the disclosure, an electronic is provided. The electronic device includes a conductive housing, a printed circuit board disposed in an inner space of the conductive housing and including a wireless communication module, a conductive plate in which the printed circuit board is disposed, a segment part configured to separate at least a portion of the conductive housing, an opening disposed between the conductive housing and the conductive plate, an antenna formed through the segment part and the opening, and a non-conductive member configured to fill at least a portion of the segment part and the opening, wherein a distance between facing surfaces of an end surface of the antenna and an end surface of the conductive plate may be configured to be not constant. 
     In accordance with another aspect of the disclosure, an electronic is provided. The electronic device includes a conductive housing, a segment part configured to separate at least a portion of the conductive housing, an opening disposed between the conductive housing and a conductive plate, an antenna formed through the segment part and the opening, a non-conductive member configured to fill at least a portion of the segment part and the opening, a display disposed at a first surface of the conductive plate, a printed circuit board disposed at a second surface of the conductive plate and including a wireless communication module, and a rear plate configured to cover a rear surface of the printed circuit board, wherein a distance between facing surfaces of an end surface of the antenna and an end surface of the conductive plate may be configured to be not constant. 
     According to various embodiments of the disclosure, by forming a distance between facing surfaces of an antenna and a conductive plate (e.g., bracket or support member) disposed adjacent to a segment part formed in a side portion of a housing not to be constant, and reducing an area in which the antenna and the conductive plate face, it is possible to provide an electronic device that maintains rigidity of the housing while maintaining a radiation performance of the antenna.

The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, Wi-Fi direct, or infrared data association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a legacy cellular network, a fifth generation (5G) network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN))). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other.
