摘要

我们设计了一个9ghz频率的超材料单元。在4.25 × 4.25 mm处采用周期结构，厚度为0.35 mm，在9 GHz处的吸光度达到99.99%。我们实现了一种矩形微带天线，并在其上加载了超材料单元格，效果有所改善。在9 GHz的反射系数(s11参数)也有可用的结果，也有助于减少天线的雷达截面，减少超过20 dB，不影响其方向性和增益。

Low-Cost Metamaterial Loaded Microstrip Antenna for Defense Applications

We have designed a Metamaterial unit-cell for 9 GHz frequency. Periodic structure was used at 4.25 × 4.25 mm with a thickness of 0.35 mm and giving us the 99.99% of absorbance at 9 GHz in simulated results. We have implemented a rectangular microstrip antenna and loaded it with Metamaterial unit-cells which provided improved results. There were results available for reflection coefficient (s11 parameter) at 9 GHz and also helping for the reduction of the Radar Cross Section of an antenna, which reduced more than 20 dB and not affected its directivity and gain.
