摘要：
Wideband dielectric resonator antennas are designed by shaping the dielectric materials. New dielectric resonator antennas of conical shape are experimentally examined and some results are verified numerically. Four different cone shapes are considered. The excitation is considered to be a coaxial probe displaced from the cone axis. Two configurations show wideband performance. The split cone achieved about 50% impedance bandwidth. The radiation patterns are computed within the band to examine the effect of the different modes excited on the radiation patterns.
