A Dielectric Resonator Antenna with Inclined Radiation Design

研究介绍了一种偏向辐射的介质谐振器天线设计方法。基于探针馈电圆柱形介质谐振器天线,在偏离馈电一侧对介质谐振器进行穿孔,并进行金属孔化。通过分析优化穿孔的大小与位置,实现了圆柱形介质谐振器天线的偏向辐射。仿真与实验吻合较好,结果表明：天线的10 d B相对阻抗带宽为7%,覆盖频率范围6.3-6.7 GHz,在阻抗带宽内,偏向辐射角度稳定在36°-37°,天线增益为6.0-7.2 d Bi。

dielectric resonator antenna（ DRA） design method with an inclined radiation is introduced.Based on the structure of the cylindrical resonator dielectric antenna fed by a probe,a hole is punched to the dielectric resonator antenna on the side away from the feed point and metallized. By analyzing and optimizing the size and position of the hole,the inclined radiation of the cylindrical DRA is achieved. Simulated and measured results have a good agreement. The results show that the 10 d B relative impedance bandwidth is 7%,covering the frequency of 6. 3 ~6. 7 GHz. The inclined radiation angle is stable from36° to 37°and the gain is 6. 0 ~7. 2 d Bi.
