Design and Simulation of Metamaterial Loaded Substrate Integrated Waveguide fed patch antenna for X-Band Military Application

Substrate Integrated Waveguide (SIW), Complimentary Split-ring resonators (CSRRs), Permitivity, millimeter waves, , Metamaterial.

The proposed structure introduces the design concept of Substrate Integrated Wave guide (SIW) fed meta material loaded patch antenna to enhance the gain of the conventional printed patch antenna for X-band military applications. The comparison between conventional and proposed SIW fed patch antenna using meta material structure is shown on the basis of parameters such as gain , bandwidth , efficiency , directivity and return loss . The Proposed SIW antenna resonates in X - band at frequency of 9.07 GHz with side by side configuration of CSRRs (Complimentary Split-ring resonators) . The animus of the study is to provide the effect of meta material loading with the help of the CSRRs structues on SIW fed patch antenna . The gain enhancement in proposed SIW fed patch antenna using meta material is from 8. 6 dB to 9.68 dB as compared to conventional SIW antenna.
