Abstract:
1. An antenna, comprising: a. a plurality of cross polarized radiating elements arranged in an array, the cross polarized radiating elements having a first polarization at +45 degrees and a second polarization at −45 degrees; b. a plurality of diplexers having a first port, a second port and a third port; the first port of each diplexer coupled to one of the first and second polarizations of at least one cross polarized radiating element; the diplexer having a first filter defining a first pass band coupling the first port to the second port and a second filter defining a second pass band coupling the first port to the third port; c. a first polarization bidirectional passive feed network and a second polarization bi-directional passive feed network, each passive feed network configured to be coupled to a single radio operating in the first pass band, each passive feed network comprising a phase shifter coupled to an input transmission line and an plurality of output transmission lines, where an output transmission line is coupled to each of the second ports of the plurality of diplexers; d. a plurality of first polarization duplexers and a plurality of first polarization duplexers, each of the plurality of duplexers having a common port, a transmit port, and a receive port, wherein the common port is coupled to one of the third ports of one of the diplexers; e. an active feed network comprising a plurality of active radios, operating in the second pass band and capable of operating at different phase angles with respect to each other wherein each active radio is has a transmitter coupled the transmit ports of a first polarization duplexer and a second polarization duplexer, and a receiver coupled to the receive ports of a first polarization duplexer and a second polarization duplexer.
