Abstract
A wireless communication device that includes an antenna module, a first communication circuit and a second communication circuit is provided. The first communication circuit performs communication by using a first communication protocol and transmits a test signal via the antenna module. The second communication circuit performs communication by using a second communication protocol and receives the test signal to calculate an isolation index based on an actual received power thereof. The second communication circuit determines that the antenna module includes two antennas when the isolation index is smaller than a threshold value to operate the first and the second communication circuits under a dual-antenna operation mode. The second communication circuit determines that the antenna module includes one antenna when the isolation index is not smaller than the threshold value to operate the first and the second communication circuits under a shared-antenna operation mode.
