摘要
研究了劈裂环谐振器(SRR)或C谐振器单元与半环天线相关联的效果。添加srr将显著降低共振频率，但指向性将几乎相同。srr是天线小型化的理想选择。增加C谐振腔将增加更多的指向性，而频移不像使用SRR单元那么重要。在接地平面为10 cm × 10 cm的情况下，两个C谐振腔单元与半环天线耦合，在920.4 MHz时的指向性为7.35 dB。可以增加接地平面以获得更好的性能。
Study of the directivity of a half-loop antenna coupled with magnetic metamaterial cells
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 10 cm × 10 cm, two cells of C resonators coupled with a half-loop antenna can have a directivity of 7.35 dB at 920.4 MHz. The ground plane can be increased to get better performances.
