Abstract :
The author considers the impact of hybrid-mode surface wave excitation on the input impedance of a loop antenna which is positioned in a double-layer air-dielectric medium. The results presented verify that, under certain geometries, the HE/sub 11/ surface wave mode will strongly influence the input impedance of the antenna.<>
