This work uses a complementary split ring resonator between the patch and the ground plane for the purpose of size miniaturization. The proposed antenna system is capable of operating in the frequency range of about 2 to 5 GHz. This wide-band design makes it viable for wide spectrum with 80 percentage effective frequency being covered in the designed band. The desired patch antenna has been simulated using Advanced System Design (ADS) simulator. The simulated results are proved to be good in agreement with cognitive radio application.展开更多
