New Compact Wearable Meta-material Antennas

Albert Sabban

Abstract :

<p>Efficient small antennas are crucial in the development of wireless communication systems. Low efficiency is the major disadvantage of small antennas. Meta material technology is used to increase the efficiency of small antennas. Design consideration, analysis, computed and measured results of wearable patch meta-materials antennas with high efficiency are presented in this paper. The antennas electrical parameters are presented. The gain and directivity of the patch antenna with Splitring resonators, SRR, is higher by 2.5dB than the patch antenna without SRR. The resonant frequency of the antennas with SRR is lower by 5% to 10% than the antennas without SRR.A wideband meta-material stacked patch antenna with air spacing is presented. The antenna bandwidth is around 10% for S11 lower than -9.5dB. The antenna gain is around 10dBi.</p>
