摘要
本文介绍了一种新颖的小型化微带天线 .利用在贴片上面开一个C型缝隙 ,使得谐振频率明显降低 ,尺寸仅是传统的半波长微带天线的 33% ,阻抗带宽略有增加 ,并且加工相对简单 .利用时域有限差分法 (FDTD)对这种天线进行了较为全面的理论分析 ,给出了输入端反射损耗特性和辐射特性 .同时给出了矩量法 (MoM)分析结果和测量结果 ,具有较好的一致性 .
A novel small microstrip patch antenna with a C-shaped slot is presented. The size of the antenna is only 33% of a conventional microstrip patch antenna and is much easier for fabrication than short patch antennas. The antenna is theoretically investigated using finite-difference time-domain (FDTD) method and its return loss and radiation properties are presented. For purpose of comparing, method of moment (MoM) results and measured results are also presented and good agreement is achieved. Such an antenna may be useful for applications where reduced antenna size and simplicity are major concerns.
