Electronic device including multi-channel grip sensor, and method for sensing capacitance change using multi-channel grip sensor

An electronic device comprising:

• a first antenna;
• a second antenna;
• a first radio frequency (RF) front-end circuit configured to transmit a first RF signal to the first antenna via a first RF signal path;
• a second RF front-end circuit configured to transmit a second RF signal to the second antenna via a second RF signal path;
• a transceiver connected to the first RF front-end circuit and the second RF front-end circuit;
• and
• a multi-channel grip sensor comprising a first channel and a second channel, wherein the first channel is connected to the first antenna via a first grip sensing path, wherein the second channel is connected to the second antenna via a second grip sensing path, and wherein the multi-channel grip sensor is configured to sense a change in a first capacitance of the first antenna through the first channel and a change in a second capacitance of the second antenna through the second channel,
• wherein the second grip sensing path comprises a portion of the first RF signal path.
