Dielectric resonator antenna: A solution for its mount on metallic body

In a Dielectric Resonator Antenna (DRA), conventionally glue or adhesive is used to fix the ceramic DRA block onto the antenna Ground Plane (GP) made of a metallic sheet. In this work a new compound ground plane has been conceived. This serves as a GP for the DRA as well as a holding structure. This technique replaces the adhesive or glue. The design has been made in such a way that no characteristics and radiation pattern of the antenna are disturbed. A full metallic configuration, suitable for practical purposes has been suggested in this work. The proposed configuration shows expected broadside radiation and ~ 6 dBi gain, with agreeable co-polar to cross-polar isolation. Finally, a prototype has been fabricated and experimentally studied. The measurement results corroborate the simulated data.
