摘要

本文设计的频率为5.8GHz。这种谐振方式利用圆形贴片天线和频率选择表面，用于专用短距离通信、RFID和无线通信应用。该天线具有半径为9.8mm的圆形贴片，模拟了介电常数rt_2.2。本文采用在其表面上有系统排列的三角形的频率选择表面，提高了增益。与圆形贴片天线相比，增加频率选择面后，增益从7.169dBi提高到10.71 dbi，回波损耗和驻波比也有所改善。这种天线的主要优点是提高了增益。在HFSS软件中对这种具有频率选择表面的圆形贴片天线进行了设计和分析。

Gain Improvement of Circular Patch Antenna with Frequency Selective Surface

This Paper has designed for the frequency 5.8GHz. This resonating mode used for dedicated short range communication, RFID and Wireless Communication applications by make use of circular patch antenna and frequency selective surface. The proposed antenna has a circular patch with radius 9.8mm and dielectric constant RT duroid 2.2 is simulated. In this paper gain has improved by using frequency selective surface which contains a systematic arrangement of triangular shape on its surface. Comparison of circular patch antenna, with adding frequency selective surface, gain has improved from 7.169dBi to 10.701dBi and returns loss and VSWR are also improved. The main advantage of this antenna is improving the gain. Design and analysis of this circular patch antenna with frequency selective surface has been done in HFSS software.
