摘要

提出了一种工作在x波段高阶模式下的宽带高增益圆极化层状圆柱介质谐振器天线。天线由两个具有不同介电常数和半径的介电层组成。结果表明，由于添加了外介电层，性能得到了显着改善，其中阻抗和轴比带宽更宽，宽侧增益更高，约为14 dBic。建立了样机并进行了测量，实验结果与仿真结果吻合较好。

HIGHER ORDER MODE LAYERED CYLINDRICAL DIELECTRIC RESONATOR ANTENNA

A wideband high gain circularly polarized layered cylindrical dielectric resonator antenna (DRA) that operates in a higher order mode is proposed in the X-band frequency range. The antenna consists of two dielectric layers having different dielectric constants and radii. The results demonstrate a considerably improved performance as a result of adding the outer dielectric layer, where wider impedance and axial ratio bandwidths have been attained in conjunction with a higher broadside gain of ~ 14 dBic. A prototype has been built and measured with close agreement between experimental and simulated results.
