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

  • a first broadband antenna, a second broadband antenna, a first multi-band transceiver, a second multi-band transceiver, and a signal processing module coupled with the first multi-band transceiver and the second multi-band transceiver;

    wherein the first broadband antenna comprises a first antenna branch and a second antenna branch, and the second broadband antenna comprises a third antenna branch and a fourth antenna branch;

    wherein the first multi-band transceiver comprises;

    a first transmitting branch of a first frequency band, a first receiving branch of the first frequency band, a first receiving branch of a second frequency band, a first multi-frequency coupler, a first transmitting branch of the second frequency band, a second receiving branch of the first frequency band, a second receiving branch of the second frequency band, and a second multi-frequency coupler;

    wherein the first transmitting branch of the first frequency band, the first receiving branch of the first frequency band, and the first receiving branch of the second frequency band are connected to the first antenna branch through the first multi-frequency coupler, and the first transmitting branch of the second frequency band, the second receiving branch of the first frequency band, and the second receiving branch of the second frequency band are connected to the third antenna branch through the second multi-frequency coupler;

    wherein the second multi-band transceiver comprises;

    a second transmitting branch of the first frequency band, a third receiving branch of the first frequency band, a third receiving branch of the second frequency band, a third multi-frequency coupler, a second transmitting branch of the second frequency band, a fourth receiving branch of the first frequency band, a fourth receiving branch of the second frequency band, and a fourth multi-frequency coupler; and

    wherein the second transmitting branch of the first frequency band, the third receiving branch of the first frequency band, and the third receiving branch of the second frequency band are connected to the second antenna branch through the third multi-frequency coupler, and the second transmitting branch of the second frequency band, the fourth receiving branch of the first frequency band and the fourth receiving branch of the second frequency band are connected to the fourth antenna branch through the fourth multi-frequency coupler.
