Dielectric resonator antennas of conical shapes are experimentally examined. The dielectric cone resides above a ground plane, and is excited by a coaxial probe. Two configurations of the cone are tested: one with the wide base placed on the ground plane, and the other with the cone inverted on the ground plane. Results show that the inverted cone achieves a wider bandwidth. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 160–161, 2001.
