Abstract

In this paper, the impedance characteristic of the electrically small loop antenna has been significantly amended by introducing a layer of MNG MTM, which is formed by BC-SRRs. The 2-GHz prototype antenna has exhibited a peak gain of 5.7 dBi and efficiency of 87.8% verifying the effectiveness of the proposed SRR-based matching layer. This matching layer can, of course, be constructed using any other MNG MTM unit cells as long as they are properly aligned with the near-field magnetic field of the small loop.
