円偏波用プリント基板型方形モノポールアンテナの広帯域化

抄録

Authors have proposed a wideband printed rectangular monopole antenna for circular polarization. The calculated and measured bandwidths (-10dB-return loss with 3dB-axial ratio) are approximately 53% and 60%, respectively. In this paper, a circularly polarized printed rectangular monopole antenna with two L-shaped slits on the ground plane and a slot on the rectangular patch is proposed for enhancement of the bandwidth. The bandwidth of 3dB-axial ratio is greater than 80%.
