宽带介质谐振器天线是通过对介质材料进行整形来设计的。对新型圆锥形介质谐振器天线进行了实验检验，并对一些结果进行了数值验证。考虑四种不同的圆锥形状。激励被认为是从锥轴位移的同轴探针。两种配置显示了宽带性能。分裂锥实现了大约 50% 的阻抗带宽。在频带内计算辐射方向图，以检查不同激发模式对辐射方向图的影响。
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.
