1. A multi-band multi-path receiving and transmitting device, comprising:

  • a broadband antenna;

    a first multi-frequency coupler;

    a second multi-frequency coupler;

    a multi-band transceiver that comprises at least two first frequency band receiving branches and at least two second frequency band receiving branches; and

    a signal processing module,wherein the broadband antenna is configured to receive at least a first frequency band signal and a second frequency band signal, and to send the first frequency band signal and the second frequency band signal to the at least the first and second multi-frequency couplers;

    wherein the first multi-frequency coupler is configured to receive the first frequency band signal and the second frequency band signal sent by the broadband antenna, and to send the first frequency band signal and the second frequency band signal to the multi-band transceiver,wherein the second multi-frequency coupler is configured to receive the first frequency band signal and the second frequency band signal sent by the broadband antenna, and to send the first frequency band signal and the second frequency band signal to the multi-band transceiver,wherein the at least two first frequency band receiving branches are configured to receive the first frequency band signal sent by the first multi-frequency coupler and the second multi-frequency coupler, and to send the first frequency band signal to the signal processing module,wherein the at least two second frequency band receiving branches are configured to receive the second frequency band signal sent by the first multi-frequency coupler and the second multi-frequency coupler, and to send the second frequency band signal to the signal processing module, andwherein the signal processing module is configured to receive the first frequency band signal sent by the at least two first frequency band receiving branches and process the first frequency band signal; and

    to receive the second frequency band signal sent by the at least two second frequency band receiving branches, and process the second frequency band signal.
