On the Effect of Scaling an Array of Complementary Split Ring Resonators (CSRRs) in the Ground Plane of a Single Microstrip Patch Antenna

Recently, there has been a significant amount of research on the use of split-ring resonators (SRRs) for their implementation in wave guides, antennas, and transmission lines for filtering, miniaturization, and sensing. In the design of the split ring resonators in transmission lines and antennas, there is not a clear technique that directly equates the dimensions of the SRRs to the equivalent circuit shown in literature. This paper investigates the change in S

of a patch antenna when the ground plane of the antenna is defected with an array differently sized split ring resonators.
