摘要

Disclosed is an electronic device including a housing including a front surface, a rear surface, and a side member, a rigid printed circuit board including a first ground, a flexible printed circuit board including a second ground and extended toward the side surface from one end of the rigid printed circuit board, a plurality of antenna elements mounted on the flexible printed circuit board and radiating a millimeter wave signal, a support member fixing the flexible printed circuit board to be at a predetermined angle with the rear surface, and a communication circuit, the first ground and the second ground allows a radiation pattern of the millimeter wave signal to have directivity in a direction of the side surface, by shielding a component, which is radiated toward at least part of the front surface or the rear surface, of a millimeter wave signal radiated from the plurality of radiators.

說明書

According to an embodiment, the communication device 151a may be positioned toward the target direction. For example, the antenna element (e.g., the antenna array 230 of FIG. 2A) included in the communication device 151a may be mounted to be extend in the X-axis direction from the PCB 210. In an embodiment, the FPC 220 on which the antenna element is mounted may be bent towards the cover glass 111 of the housing 110.

According to an embodiment, the FPC 220 may be bent at the angle specified by the support member 310. The support member 310 may be fixed such that the FPC 220 is bent at a specified angle to face the specified direction. According to various embodiments, the support member 310 may be formed by a cushion, a rib, a bracket, a part of the housing 110, or the like.

According to an embodiment, the ground included in the PCB 210, for example, the PCB ground may reduce at least part of a millimeter wave signal radiated from the antenna elements 231, 232, 233, and 234, for example, a component radiated toward the PCB 210. For example, the first region 31 may indicate a blocking region in which a millimeter wave signal is blocked by the PCB ground. A component of the millimeter wave signal in the direction of the rear cover 112 of the housing 110 corresponding to the first region 31 may be blocked.
