介质埋藏天线可避免传统覆盖天线裸露在空气中受到氧化腐蚀等问题,同时增强了天线的隐蔽性、减小了天线的尺寸,扩展了天线的带宽、天线波束变窄,有助于提高天线的增益。使用电磁仿真软件Ansoft HFSS对该天线进行了优化设计和仿真实验,并制作了实物天线,进行了测试。仿真和实测结果表明:该天线S11≤-10 d B的相对带宽达到92.3%,具有超宽带特性。在工作频率处,增益可达到10.2 d B并且具有较好的定向辐射特性,可以满足工程项目的需要,具有一定的工程应用价值。
The buried antenna of the medium can avoid the problem that the traditional covered antenna is oxidized and corroded in the air and the like, meanwhile, the concealment of the antenna is enhanced, the size of the antenna is reduced, the bandwidth of the antenna is expanded, the beamwidth of the antenna is narrowed, Gain. The antenna was optimized design and simulation experiment using electromagnetic simulation software Ansoft HFSS, and the real antenna was made and tested. The simulation and experimental results show that the relative bandwidth of S11≤-10 d B is 92.3% and has ultra-wideband characteristics. At the operating frequency, the gain can reach 10.2 d B and has good directional radiation characteristics, which can meet the needs of the project and have certain engineering application value.
