摘要

本文提出了一种利用共面波导馈电改善新型微带天线带宽特性的设计方法。该方法在传统共面波导馈电的基础上增加了三段馈电结构(TSFS)，并在矩形辐射贴片上增加了倒角，提高了天线的检测性能。该天线可工作在500MHz ~ 1120MHz频段，该频段的峰值增益为4.6dB，平均增益为3.4dB，增益较高。从方向图可以看出，该天线具有良好的全向辐射特性，能够接收来自空间不同方向的电磁信号。根据优化结果制作了天线，并利用矢量网络分析仪对天线的输入S11和驻波比进行了测量，测量结果与仿真结果一致，验证了天线的性能。

Research on Performance Enhancement of Radio Frequency Antenna Based on Three Section Feed Structure and Chamfered Design

In this paper, we propose a design method to improve the bandwidth characteristics of a new microstrip antenna using coplanar waveguide feed. This method adds a three section feed structure (TSFS) on the basis of the conventional coplanar waveguide feed and the addition of chamfers to the rectangular radiating patch to improve the detection performance of the antenna. The antenna can operate in the frequency band from 500MHz to 1120MHz, with a peak gain of 4.6dB and an average gain of 3.4dB in this band, with high gain. The directional diagram shows that the antenna has good omnidirectional radiation characteristics and can pick up electromagnetic signals coming from different directions in space. According to the optimization results, the antenna is fabricated, and the input S11 and standing wave ratio (SWR) of the antenna are measured using a vector network analyzer, and the measured results are consistent with the simulation results, which verifies the performance of the antenna.
