A study of loop antenna miniaturization using split ring resonators

Abstract

In this paper we demonstrate the miniaturization of a loop antenna through simulation and experiment using synthetic reactive elements, namely split ring resonators (SRRs), embedded in the substrate of the antenna. Two designs were considered with SRRs both in and out of the plane of the substrate. Simulation results show that antenna size can be reduced up to thirty eight percent for both designs. However, due to ease of fabrication, the in-plane configuration is the preferred design. Simulation and experimental results are presented.
