Abstract
An antenna has a relatively thick primary dielectric between a ground plane and a conducting radiating element being fed by a conducting transmission line, first and second thin dielectrics on opposite sides of the primary dielectric, the relatively thick primary dielectric having a relatively lower dielectric constant than that of at least the second thin dielectric to increase the bandwidth transmission capability of the transmission line for a given impedance, the second thin dielectric couples substantially less power than is coupled with the primary dielectric and the second thin dielectric is of relatively higher dielectric constant promoting surface wave coupling and reduction of wave losses.
