| Abstract: | A hemispherical dielectric resonator antenna excited by a microstrip feedline through a narrow slot in a thick ground plane is studied theoretically and experimentally. A numerical method based on a combination of the spectral Green's function, modal Green's function, and the method of moment is used to investigate the input characteristics of the dielectric resonator antenna system. The effects of ground‐plane thickness on input resistance, resonant frequency, and impedance bandwidth of the dielectric resonator antenna are discussed. © 2000 John Wiley & Sons, Inc.
