## Abstract Hemispherical dielectric resonator (HDR) antenna excited with a slot at the short circuited end of waveguide is analyzed theoretically and verified experimentally. The analysis is based on numerical solution of coupled integral equations discretized using the method of moments (MoM). Th

As an example, the dual-reflector antennas of spheroidal wave function distribution and uniform distribution have been used. For spheroidal wave function distribution, we have obtained transmission efficiency of nearly 95%, whereas for the uniform distribution, only 80% has been obtained. ## CONCLU
