Electronic device including antenna

An electronic device comprising:

• a first non-conductive cover including a first planar portion defining a first surface of the electronic device;
• a second non-conductive cover including a second planar portion defining a second surface of the electronic device opposite the first surface, and a curved portion defining a first portion of a lateral surface of the electronic device, wherein as viewed cross-sectionally the lateral surface is at least partially at an elevation between respective elevations of the first surface and the second surface;
• a frame including a metal inclusive portion defining a second portion of the lateral surface of the electronic device;
• an antenna module including a patch antenna configured to transmit signals through at least part of the first portion of the lateral surface of the electronic device, and
• wherein, viewed cross-sectionally, the frame comprises a non-conductive portion disposed at least partially between at least the lateral surface and at least part of a radiating surface of the patch antenna facing the lateral surface, the non-conductive portion of the frame configured to support the curved portion of the second non-conductive cover,
• wherein an air gap is provided between at least the radiating surface and the non-conductive portion of the frame,
• wherein the antenna module is disposed between at least the first non-conductive cover and the second non-conductive cover such that the radiating surface faces at least the lateral surface, and
• wherein when viewed from the lateral surface, at least a half of the radiating surface overlaps with the first portion of the lateral surface and a remaining portion of the radiating surface overlaps with the second portion of the lateral surface.
