EXPERIMENTAL STUDY OF DIELECTRIC DISC ANTENNA BACKED BY A METAL PLATE

Abstract

Numerical evaluation of some of the theoretical aspects of the earlier theoretical study by the authors on surface waves launched on dielectric discs with a metal disc sandwiched between them is presented. Experimental results on the transverse and radial field decay and vertical and horizontal radiation patterns, when the dielectric discs, are excited at X band by a double cone placed symmetrically alii both sides of the struclure are reported.
