Abstract: An electronic device and a method of grip recognition of the electronic device are provided. The electronic device includes an antenna, a radio communication device having a coupler, a memory, and a processor which is electrically connected to the radio communication device and the memory, wherein the memory includes instructions, executable by the processor, wherein the processor is configured to detect a first signal being transmitted and a second signal being received through the antenna using the coupler, calculate a reflection coefficient of the antenna based on the first signal and the second signal, determine a signal magnitude and a phase corresponding to the reflection coefficient, and determine whether the electronic device is being gripped based on the signal magnitude and the phase.
