Abstract
A microstrip antenna device having a dielectric layer, a conductive patch of a chosen shape on one side of the layer and, on the other side of the layer, a conductive plate forming a ground plane; and, a feed circuit comprising at least one microstrip line connected to the conductive patch and implanted in the dielectric layer in the same plane as the conductive patch. The thickness of the dielectric layer opposite the microstrip line is greater than the thickness opposite the periphery of the microstrip line. Further, the thickness of the dielectric layer opposite the conductive patch is greater than the thickness opposite the microstrip line, and also greater than the thickness opposite the periphery of the conductive patch.
