Abstract
A laminar patch antenna comprises a ground plane element with a cross shaped aperture sandwiched between two dielectric layers with a patch radiator on one dielectric layer and a transmission line circuit on the other dielectric layer. The transmission line circuit has linear conductors overlying respective sectors between slots of the aperture, the conductors providing a feedline and stub projection with lines of similar type overlying opposite sectors of the cross and conductors of different type overlying adjacent sectors of the cross.
