Description

[Technical Field] An embodiment(s) of the disclosure relates to an electronic device, e.g., an electronic device including an antenna module. [Background Art] The term "electronic device" may refer to a device that performs a specific function according to a program installed therein, such as a home appliance, an electronic scheduler, a portable multimedia player, a mobile communication terminal, a tablet PC, a video/audio device, a desktop or laptop computer, or an in-vehicle navigation system. For example, such electronic devices may output stored information in the form of sound or video. As electronic devices become highly integrated and ultra-high-speed, high-capacity wireless communication becomes commonplace, various functions may be incorporated into a single electronic device, such as a mobile communication terminal. For example, not only communication functions but also functions such as entertainment (e.g., playing games), multimedia (e.g., playing music or videos), communication and security (e.g., for mobile banking), or scheduling and electronic wallet functions are being integrated into a single electronic device. As personal or portable communication devices such as smartphones become more widespread, users' demand for portability and convenience of use is increasing. For example, a touchscreen display may serve as a screen, i.e., an output device for visual information, and may also provide a virtual keypad that replaces a mechanical input device (e.g., a button-type input device). Accordingly, portable communication devices or electronic devices may be miniaturized while still providing the same or even enhanced usability (e.g., a larger screen). On the other hand, as flexible displays, such as foldable or rollable displays, become commercialized, the portability and convenience of use of electronic devices are expected to be further improved. An electronic device including a flexible display may be portable in a folded or rolled state of a plurality of different structures (e.g., housings), and may provide a large screen in an unfolded state, thereby improving portability and convenience of use. The above-described information may be provided as related art for the purpose of helping understanding of the disclosure. No claim or determination is made as to whether any of the foregoing is applicable as prior art in relation to the disclosure. [Detailed Description of the Invention] [Technical Solution] According to an embodiment of the disclosure, an electronic device may include a housing including a front surface, a rear surface facing a direction opposite to the front surface, and a side wall at least partially surrounding a space between the front surface and the rear surface, a camera assembly disposed at one edge of the space, adjacent to the side wall, a support protrusion protruding from the camera assembly in a direction, a first radiator disposed as at least a portion of a first portion of the side wall adjacent to the camera assembly and configured to perform wireless communication in a first frequency band, an antenna module at least partially disposed between a second portion of the side wall adjacent to the first portion and the camera assembly, the antenna module configured to perform wireless communication in a second frequency band, and a first flexible printed circuit board extending from the antenna module and disposed at least partially between the first portion and the camera assembly.
