CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0136783, filed on Oct. 30, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

Field

The disclosure relates to an electronic device including an antenna module.

Description of Related Art

With the development of wireless communication technology, electronic devices (e.g., electronic devices for communication) are commonly used in daily life; thus, content use is increasing. While data traffic rapidly increases, as frequency demand increases, a technology for using a high-frequency band or an ultra-high frequency band (e.g., millimeter wave (mmWave)) that can more easily gradually transmit data for wireless communication is being developed. The electronic device may include a highly directional phase array antenna (e.g., antenna array) in order to appropriately operate in a mobile environment. The electronic device may use a beam forming system that processes a transmission signal or a reception signal so that energy radiated from the phase array antenna is concentrated in a specific direction in a space.

Space may be limited because of characteristics of an electronic device such as a smartphone that should focus on mobility. Recently, because a slimming form factor has been pursued, it is becoming more difficult to dispose an antenna system using millimeter waves crossing a high frequency band in consideration of dependencies and interrelationships between mutually operating components. In the case of the millimeter wave, an antenna system in which a large number of radiating elements are tightly coupled and having a narrow-beam and high-gain is required, but because of propagation characteristics that are high in straightness (e.g., direction) and sensitive to a path loss, coverage (communication range) of the antenna system disposed together with various components and/or structures in the electronic device is limited.

SUMMARY

Embodiments of the disclosure provide an electronic device including an antenna module for extending coverage.

According to various example embodiments of the disclosure, an electronic device includes: a housing including a front plate, a rear plate disposed at a side opposite the front plate, and a side bezel enclosing at least a portion of a space between the front plate and the rear plate; a display disposed in the space and visible through at least a portion of the front plate, wherein the display includes: a first layer including a plurality of pixels; and a second layer disposed at the first layer and including an opening; and an antenna module disposed in the space, wherein the antenna module includes: a printed circuit board including a first surface facing away from the first layer through the opening and a second surface facing opposite the first surface; at least one antenna element disposed on the first surface, or inside the printed circuit board closer to the first surface than the second surface; and a communication circuit disposed at the second surface of the printed circuit board, the communication circuit configured to transmit and/or receive signals of a selected or designated frequency band through the at least one antenna element.
