摘　　要：提出一种宽带的高介电常数圆柱形介质谐振器天线,并进行了分析与设计.采用在圆柱形陶瓷介质谐振器中穿孔及结合H形缝隙耦合馈电,有效地克服了高介电常数介质情况下工作频带较窄的缺点,获得了12.6%的阻抗带宽,并具有介质谐振器尺寸小的优点和较好的辐射特性.A wideband cylindrical dielectric resonator antenna with high dielectric constant is proposed, analyzed and designed. The ceramics cylindrical dielectric resonator antenna with an air gap excited by an H-shaped slot is adopted to overcome the narrow bandwidth under the condition of high dielectric constant. An impedance bandwidth of 12.6% has been achieved with a smaller size of the dielectric resonator and better radiation performance.
