| 摘 要： | 提出了一种同时具有圆极化和线极化的双频新型开槽微带天线的设计方法．天线双频工作是通过分别在靠近方形微带天线的两个辐射边处各开一个平行的窄槽来实现的．在较低的谐振频率处圆极化的获得是通过在天线辐射单元上适当地设置摄动元素，并将馈电点移到辐射单元的对角线上．一个设计天线的测试结果给出了该天线在两个谐振频率上具有很好的圆极化及线极化的天线性能． |

| Abstract: | This paper presents a new method for designing a dual-frequency patch antenna with circular and linear polarizations. Dual-frequency operations are behaved by etching two narrow slots close to the radiating edges of a rectangular patch. The circular polarization at the lower resonant frequency of the dual-frequency antenna can be achieved by setting a perturbation segment at an appropriate location in the patch element, and placing the feed point on the diagonal axis. Several experimental results of a designed antenna show the good characteristics for circular and linear polarizations at both resonant frequencies. |
