1. An electronic device comprising:
a first antenna;
a second antenna;
a first communication circuit configured to operate in a reception mode or a transmission mode and to process a radio frequency (RF) signal of a first frequency band supporting a first communication scheme;
a second communication circuit configured to operate in the transmission mode or an idle mode without operating in the transmission mode and to process an RF signal of a second frequency band supporting a second communication scheme, the first communication circuit and the second communication circuit being disposed separately;
a first connection circuit configured to electrically connect the first antenna to one of the first communication circuit or the second communication circuit;
a second connection circuit configured to electrically connect the second antenna to one of the first communication circuit or the second communication circuit, the first connection circuit and the second connection circuit being disposed separately; and
a processor configured to control an operation of the first connection circuit and the second connection circuit based on an operation state,
wherein the processor is configured to:
determine whether the first communication circuit operates in the transmission mode or the reception mode,
in case that the first communication circuit operates in the transmission mode:
determine whether the first communication circuit transmits a first signal of the first communication scheme,
in case that the first communication circuit operates in the transmission mode and the first communication circuit does not transmit the first signal, control the first connection circuit and the second connection circuit so that both the first antenna and the second antenna are electrically connected to the second communication circuit, and
in case that the first communication circuit operates in the reception mode, maintain a state in which the first communication circuit is connected to the first antenna and the second communication circuit is connected to the second antenna,
wherein, in case that the first communication circuit operates in the transmission mode and the first communication circuit does not transmit the first signal, the second communication circuit is configured to:
receive a first RF signal through the first connection circuit and the first antenna and a second RF signal through the second connection circuit and the second antenna,
process the first RF signal in an overlap frequency band and the second RF signal in the second frequency band, wherein the overlap frequency band is a frequency band at which the first frequency band overlaps the second frequency band, and
output the processed first RF signal and the processed second RF signal to the processor, and
wherein, in case that the first communication circuit operates in the reception mode, the second communication circuit does not receive a RF signal in the first frequency band through the first connection circuit and the first antenna.
