An electronic device with antenna switch comprises a first antenna, a first proximity sensor, a second antenna, a detection module, a determination module and a control module. The first proximity sensor is located with the first antenna at a first side portion of the electronic device. The detection module detects an approach signal from the first proximity sensor. The determination module determines whether the strength of the approach signal is stronger than a threshold value in real time. The control module initiate the second antenna to receive signals through the switch if the strength of the approach signal is stronger then the strength of the threshold value.
