Electronic device comprising lateral antenna structure

A circuit member disposed in an opening defined between a housing and a frame of an electronic device, the frame at least partially including a conductive material, surrounding a side surface of the housing, and comprising an insertion hole, the circuit member comprising:

• a substrate;
• a connector extending from the substrate and connected to a communication interface of the electronic device;
• a switch disposed in the housing and facing the insertion hole of the frame;
• and
• a contact portion including a conductive material, the contact portion being disposed on the substrate of the circuit member and in contact with the frame,
• wherein the opening comprises a first section positioned in a first direction with respect to the contact portion, and a second section positioned in a second direction opposite to the first direction with respect to the contact portion, the second section having a length greater than a length of the first section, and
• wherein the frame comprises a first portion corresponding to a first section of the opening, and a second portion corresponding to the second section of the opening, the frame being electrically connected to the connector and configured to transmit and/or receive a communication signal.
