Abstract :
This paper presents a novel, highly compact, and multiband circular patch antenna. The paper includes the analytical study on the meandered circular patch antenna and single unit cell of a Split Ring Resonator based metamaterial substrate for the multiband operations and further lowering of resonant frequencies obtained with shorting posts observed from the return loss curve. Circuit model of SRR configuration is also presented. Effects of complementary SRR slot on the ground plane are parametrically studied. Proposed configuration with huge amount of compactness of around 48% covers two bands of microwave regime around 4-12 GHz i.e. in C and X-bands and thus applications pertaining to this regime are also discussed.
