ABSTRACT:
A coupling matrix for a circular array microwave antenna is described which permits the formation and phasing of multiple beams from a circular array. The present invention provides a beam forming and steering means for a circular array which utilizes at least one radio frequency signal as an input to a matrix of passive proximity couplers. These passive proximity couplers are configured in rows and are operable to form the radio frequency signal. These couplers are interconnected into distinguishable groups.
