Abstract
A microstrip antenna structure comprising a radiator layer that includes a substrate layer and a radiator patch that is disposed on one surface of the substrate layer; a ground plane; and support elements, formed as an integral part of either the radiator layer or the ground plane, for maintaining a dielectric space between the radiator patch and the ground plane that includes an air gap of predetermined thickness between the substrate layer and the ground plane. The present invention also includes a method for constructing such a microstrip antenna structure.
