%X We have designed a Metamaterial unit-cell for 9 GHz frequency. Periodic
structure was used at 4.25 กม 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.
