1. A system for the coexistence between a plurality of wireless communication modules sharing a single antenna, comprising:

  • a first transceiving path coupled to an antenna;

    a second transceiving path coupled to the first transceiving path;

    a first wireless communications module coupled to the first transceiving path and transmitting or receiving a plurality of first wireless signals via the first transceiving path;

    a second wireless communications module coupled to the second transceiving path and capable of transmitting and receiving a plurality of second wireless signals via the first and the second transceiving paths; and

    a directional coupler that attenuates signal strengths of the second wireless signals passing through the second transceiving path, and adds the attenuated second wireless signals to the first wireless signals passing through the first transceiving path,wherein one of the first wireless communications module and the second communications module is a LTE module and the other one of the first wireless communications module and the second communications module is a WLAN module.
