Abstract

In embodiments, an electronic device may include a housing having an inner space, a printed circuit board (PCB) disposed in the inner space of the housing, a first antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a first frequency band, at least one second antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a second frequency band different from the first frequency band, and a flexible substrate electrically connecting the PCB and the first antenna structure. The flexible substrate may include a first connecting portion electrically connected to the PCB, an interconnecting portion extended from the first connecting portion to the first antenna structure, at least one branch portion branched from at least a part of the interconnecting portion, and extended to the at least one second antenna structure, at least one first conductive path disposed in the interconnecting portion, and electrically connecting the first connecting portion and the first antenna structure, and at least one second conductive path disposed in the interconnecting portion and the at least one branch portion, and electrically connecting the first connecting portion and the at least one second antenna structure.
