Abstract
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.
Claims11
An electronic device with antenna switch, comprising:
- a first antenna that is predefined as a silent antenna to receive a signal;
- a first proximity sensor that is located with the first antenna at a first side portion of the electronic device;
- a second antenna that is located at a second portion of the electronic device away from the first portion;
- a detection module that detects an approach signal from the first proximity sensor;
- a determination module that determines whether the strength of the approach signal is stronger than a threshold value in real time;
- a control module that initiate the second antenna to receive signals if the strength of the approach signal is stronger then the strength of the threshold value;
- and
- a processor that controls the detection module, the determination module and the control module.
An antenna switching method of an electronic device with an antenna switch, comprising:
- initiating a first antenna to receive signals;
- detecting an approach signal from a proximity sensor locating with the first antenna;
- detecting whether the strength of the approach signal is stronger than a threshold value;
- and
- initiating the second antenna when the strength of the approach signal is stronger than the threshold value.
