1. An electronic device comprising:
a first communication circuit comprising:
a first transmission port which outputs a transmission signal of first communication; and
a first reception port which receives a reception signal of the first communication;
a second communication circuit comprising:
a second transmission port which outputs a transmission signal of second communication; and
a second reception port which receives a reception signal of the second communication;
a first branching filter connected to a first antenna and the first communication circuit;
a second branching filter connected to a second antenna and the first communication circuit;
a first switch connected to the second communication circuit through the second transmission port and the second reception port and connected to switch between the first branching filter, the second branching filter, and a third antenna; and
a fourth antenna connected to the second communication circuit through the second reception port,
wherein the second communication circuit:
controls the first switch to perform a first function through which a transmission signal of the second communication is transmitted by one of the first antenna and the second antenna and, simultaneously with the transmission, a reception signal of the second communication is received by a remaining one of the first antenna and the second antenna,
controls the first switch to perform a second function through which a transmission signal of the second communication is transmitted by one antenna of the first antenna and the second antenna and a reception signal of the second communication is received by the one antenna, and
controls the first switch to perform a third function through which a reception signal of the second communication is received by the third antenna and the fourth antenna.
