Abstract

A wideband and replaceable dielectric resonant antenna (DRA) excited by a probe is investigated. The proposed wideband DRA consists of a probe platform and a solid cylindrical dielectric resonator, and two magnets are applied to fix them. In this way, the dielectric resonator can be easily replaced. Therefore, three kinds of wideband DRAs with impedance bandwidth of 35.8%, 56.6% and 74% are designed. The reflection coefficient, radiation mode and antenna gain of the cylindrical DRA were analyzed by using HFSS ANSYS.

宽带和可更换圆柱形介质谐振器天线

研究了一种由探针激发的宽带可更换介质谐振天线。提出的宽带DRA由一个探头平台和一个固体圆柱形介电谐振器组成，并使用两个磁体固定它们。这样，介质谐振器可以很容易地更换。为此，设计了阻抗带宽分别为35.8%、56.6%和74%的三种宽带dra。利用HFSS ANSYS分析了圆柱形DRA的反射系数、辐射模式和天线增益。
