ABSTRACT:
A wireless communication module used for a portable electronic device comprises a first antenna module and a second antenna module, which first antenna module has a first antenna for transmitting and receiving of wireless signals, an electronic circuit for coding and decoding of wireless signals, and a detector for detecting of signal intensity, and which second antenna module has a signal transmission line and a second antenna for transmitting and receiving of wireless signals; the first antenna module connects to the second antenna module via the signal transmission line of the second antenna mode to have the detector of the first antenna module can detect and compare the signal intensity of the first and second antennas, when a weaker signal is detected at the first antenna of the first antenna module, the signal transmission/receiving task is actively shifted to the second antenna of the second antenna module; the wireless signal received by the first antenna of the first antenna module or by the second antenna of the second antenna module after shifting is sent to the electronic circuit of the first antenna module for decoding into a digital signal, therefore, the wireless communication module of the invention can solve the problem of interruption due to adverse surrounding conditions.
