Method and system for manifold antennas for multiband radios

摘要

Systems and methods are disclosed to intelligently employ antenna resources in a manner that may reduce interference between communications signals even in instances where multiple separate frequency band communications need to be supported in a vehicle of limited size. A manifold antenna system is proposed that provides a scheme and a physical construct whereby multiple individual radio receiver/transmitter units may share a limited number of transmitting and receiving antennas. The disclosed manifold antenna system is particularly adaptable to aircraft, spacecraft, vessel or vehicle applications where there is limited room for mounting a number of individual antennas as may be needed to support each radio receiver/transmitter unit in an effort to minimize an amount of interference as is conventionally caused by having transmitting antennas located in too close a proximity to receiving antennas.

1. An antenna system for a vehicle, comprising:
a receive antenna system including at least one receive antenna, the at least one receive antenna processing incoming communications on frequencies in multiple communicating bands; a transmit antenna system including:
a plurality of transmit antennas, each of the transmit antennas transmitting outgoing communications on frequencies in an individual communicating band that is one of the multiple communicating bands and that is different from an individual communicating band over which outgoing communications are transmitted on each of the other transmit antennas, anda plurality of transmit combiners respectively associated with the plurality of transmit antennas, each of the plurality of transmit combiners combining outgoing communications on the frequencies in the individual communicating bands on which the respective transmit antenna transmits the outgoing communications.
