—The effect of associating Split Ring Resonators (SRR) or C resonators cells with a half-loop antenna is studied. Adding SRRs will shift down considerably the resonance frequency but the directivity will be almost the same. SRRs are good candidate for antenna miniaturization. Adding C resonators will increase more the directivity while the frequency shifting is not as important as with SRR cells. With a ground plane of 10cm x 10cm, two cells of C resonators coupled with a half-loop antenna can have a directivity of 7.35dB at 920.4MHz. The ground plane can be increased to get better performances.
