摘要

提出了一种新型的轴对称介质谐振器天线(DRAs)，工作频率在5.8 GHz左右。每个元件使用一个高介电常数圆柱形谐振器和一个截锥形低介电常数谐振器。研究了两种微带馈电DRAs。通过耦合谐振模式，第一类和第二类DRA的分数阻抗带宽分别为15.6%和19.7%。

New antennas with dielectric resonators of axial symmetry

New type of dielectric resonator antennas (DRAs) with axial symmetry are proposed for frequencies around 5.8 GHz. Each element uses a high permittivity cylindrical resonator and a low permittivity resonator of a truncated cone shape. Two types of microstrip-fed DRAs were investigated. By coupling the resonance modes, the first type and the second type DRA exhibit fractional impedance bandwidth of 15.6% and 19.7%, respectively.
