摘　　要：设计了一种新型的基于微带贴片馈电的介质谐振器天线.天线的介质杆设计为锥削结构,采用具有嵌入式微带线的圆形贴片进行馈电.通过调节微带线嵌入圆形贴片的深度和宽度,获得较宽的阻抗带宽.天线样品的测试结果与设计仿真结果吻合良好.天线阻抗带宽(|S11|<-10dB)为7.1%(5.73~6.14GHz),频段内的平均增益超过11.1dBi.在工作频率5.8GHz处,天线的增益达到11.2dBi,相应的口径效率为84.1%.A novel dielectric resonant antenna based on microstrip patch feed is proposed.The dielectric rod has simple structure,which is tapered.The antenna is fed by a circle patch with embedded microstrip lines.By adjusting the width and depth of microstrip line embedded in circle patch,a wide impedance bandwidth can be obtained.The simulation and measurement results are in good agreement and show the proposed antenna possesses encouraging properties,i.e.,a impedance bandwidth (|S11|<-10 dB)is 7.1%(5.73~6.14 GHz)and the average gain beyond 11.1 dBi.At the work frequency of5.8 GHz,the gain up to 11.2 dBi and the aperture efficiency is up to 84.1%.
