ABSTRACT:
An antenna includes a first element that attaches to the outside surface of a window and includes a disk-shaped first dielectric substrate with a pair of major surfaces covered by an electrically conductive layer. The electrically conductive layers are connected by a plurality of tuning posts extending through the first substrate. A second element is attached to the inside surface of the window adjacent to the first element. The second element includes a disk-shaped second dielectric substrate having first and second major surfaces with an edge therebetween. A circular first electrode is centrally located on the first major surface facing the first element and an annular second electrode extends around the first electrode on the first major surface. A third electrode covers the second major surface of the second substrate and a shunt connects the second and third electrodes at the substrate edge. A transceiver connector is located on the edge of the second substrate opposite the shunt for applying an excitation signal between the first and third electrodes.
