Abstract
An antenna apparatus (200) including a forward link antenna array (212, 214, 216, 218) and a reverse link antenna array (210, 214, 220, 222) coupled by a plurality of circulators (224, 226, 228). The circulators direct the signals for the forward link and reverse link to and from the appropriate antenna elements in the appropriate direction. The forward link and reverse link antenna arrays use a common set of coaxial cables (230) to communicate with the base station circuitry.
