Hemispherical Dielectric Resonator Antennas over Non-Planar Surfaces for Direction Finding Systems

Abstract

In this paper, hemispherical DRA array mounted on or embedded in a hollow circular cylindrical ground structure is used for direction finding systems. In the proposed array only one DRA element is active and the others are parasitic. The d irection of the received signal will be determined by the relat ion between the received signal strengths at each element of the array.
