摘要
本文介绍了一种简单、紧凑、在8ghz到12GHz频段上具有10dB回波损耗(VSWR< 2)的CPW馈电单极孔径天线，用于x波段应用。天线包括接地面、矩形槽和交叉矩形激励短段。该天线非常简单，易于制造。该天线设计在介电常数εr =4.4、尺寸为30mm×25mm×1.5mm的廉价FR4_Epoxy基板上，得到了天线的带宽回波损耗、辐射方向图和增益等基本参数，均符合可接受的天线标准。采用有限元仿真工具(HFSS V 13.0)对所提出的天线进行了分析和优化，该天线适用于雷达和卫星通信系统，覆盖了整个x波段(8-12)GHz，效率为97%。
A CPW fed X-Band antenna for satellite & radar applications
This paper presents the analysis of simple, compact, CPW- fed monopole aperture antenna with 10dB return loss (VSWR<;2) band from 8 GHz to 12GHz for X-band applications. The antenna includes ground plane, rectangular slot and a crossed rectangular exciting stub. The antenna is very simple and easy to fabricate. The proposed antenna is designed on an inexpensive FR4_Epoxy substrate with dielectric constant of εr =4.4 and with the size of 30mm×25mm×1.5mm The fundamental parameters of the antenna such as bandwidth return loss, radiation pattern, and gain are obtained All justifies the acceptable antenna standards. Simulation tool, based on the finite element method (HFSS V 13.0) has been used to analyze and optimize the proposed antenna Antenna is applicable for radar and satellite communication system It covers complete X-band (8-12) GHz and having the efficiency of 97%.
