Abstract
An antenna having a passive feed network in one band, and an active radio network in an adjacent band, is provided. The antenna includes radiating elements arranged in an array dimensioned to transmit and receive RF signals. The antenna includes diplexers having a first port, a second port and a third port. The first port of each diplexer coupled to at least one radiating element. The diplexer has a first filter coupling the first port to the second port and a second filter coupling the first port to the third port. A passive feed network includes a phase shifter, which is coupled to an input transmission line and a plurality of output transmission lines. Each of the output transmission lines may be coupled to one of the second ports of one of the diplexers. An active radio is coupled to each of the third ports of the plurality of diplexers.
