摘要

本文采用表面短探针馈电技术研究了圆柱形介质谐振器天线(CDRA)中另一种高阶模式HEM21δ模式的激发。本文也给出了由于金属扰动引起的模态场变化。在电场分布对称的h面，共极化增益增加了2dBi，而在电场分布不对称的e面，共极化增益减少了2dBi。

Single coax-fed Cylindrical Dielectric Resonator Antenna using higher order mode for pattern diversity

In this paper we have investigated the excitation of the HEM21δ mode, another higher order mode in Cylindrical Dielectric Resonator Antenna (CDRA) by using a surface short probe feeding technique. The modal field variation due to metallic perturbations for this field configuration has also been presented here. The co-polarized gain has enhanced by 2dBi in H-plane with symmetrical E-field distribution but in case of E-plane the gain is decreased by 2dBi with asymmetrical distribution of E-field.
