1. An electronic device comprising:
a first antenna configured to transmit and receive a first radio frequency (RF) signal of a first frequency band;
a second antenna spaced apart from the first antenna in a first direction, and configured to transmit and receive a second RF signal of a second frequency band that is lower than the first frequency band;
a third antenna spaced apart from the first antenna in a second direction that is opposite to the first direction, and configured to transmit and receive a third RF signal of a third frequency band that is lower than the second frequency band;
a first grip sensor configured to detect proximity of an external dielectric body based on a capacitance change of the first antenna;
a second grip sensor configured to detect proximity of the external dielectric body based on a capacitance change of the second antenna;
a third grip sensor configured to detect proximity of the external dielectric body based on a capacitance change of the third antenna; and
a processor operatively connected to the first grip sensor, the second grip sensor, and the third grip sensor,
wherein when detecting the proximity of the external dielectric body, the first grip sensor, the second grip sensor, and the third grip sensor transmit proximity information to the processor, and
wherein the processor is configured to determine that the external dielectric body is in proximity to the first grip sensor when receiving the proximity information from the second grip sensor and the third grip sensor.
