Metamaterial-inspired high directive half-loop antenna

摘要

This paper presents a high directive antenna consisting of a half-loop antenna coupled with C resonators cells. With a global size of 10cm × 10cm × 11.4cm the directivity of the antenna is 7.3dB at 920.4MHz. If the orientation of the C resonators is changed, the resulting antenna still has directivity of 7.4dB but with a little increase of the resonance frequency. One can notice that the back radiation is diminished.
