Abstract

|A new miniaturized patch antenna based on a metal strip is proposed in this paper. The antenna is designed by adding a middle metal strip layer to the substrate of a traditional rectangular patch antenna. By increasing the length of the metal strip, the working frequency of the patch antenna can be continuously reduced without signi(cid:12)cantly impacting the radiation pattern. The simulation results indicate that as the metal strip length increases from 5 mm to 25 mm, the working frequency of the patch antenna decreases from 2.39 GHz to 1.84 GHz, and its gain decreases from 6.72 dBi to 5.4 dBi. Two antenna samples with metal strip lengths of 5 mm and 20 mm are fabricated. The experimental results indicate that their working frequencies are 2.64 GHz and 2.43 GHz, respectively. And the radiation patterns of two antennas are consistent with the simulated results. All results con(cid:12)rm the eﬀectiveness of the proposed miniaturization method.

基于金属条的贴片天线小型化新方法研究

本文提出了一种新型的基于金属带的小型化贴片天线。该天线是通过在传统矩形贴片天线的基片上增加中间金属条层来设计的。通过增加金属条的长度，可以在不显著影响辐射方向图的情况下连续降低贴片天线的工作频率。仿真结果表明，当金属带长度从5 mm增加到25 mm时，贴片天线的工作频率从2.39 GHz减小到1.84 GHz，增益从6.72 dBi减小到5.4 dBi。制作了金属带长度分别为5mm和20mm的天线样品。实验结果表明，它们的工作频率分别为2.64 GHz和2.43 GHz。两根天线的辐射方向图与模拟结果基本一致。所有结果都证明了所提出的小型化方法的有效性。
