Abstract
An monolithic surface mountable antenna. The antenna comprises a ground plane, two dielectric layers separated by a conductive intermediate layer and a plurality of conductive regions on a top surface. Ground vias pass through the dielectric layers and connect one or more of the conductive regions to the ground plane. At least one signal via is connected to one of the plurality of conductive regions.
