Summary:
This paper presents the metasurface used for enhancing of gain, impedance bandwidth (ZBW) and axial ratio bandwidth (ARBW) by placed metasurface above a circularly polarized right angle slot antenna (CP-SA). The CP-SA with metasurface can increases ZBW and ARBW, implying an improvement of 632% and 434%, respectively. The overlap bandwidth of ZBW and ARBW is 400 MHz. Moreover, the radiation patterns can redirect into unidirectional. The gain increases 6.3 dB when compared with the CP-SA alone. This proposed antenna is low profile, lowcosts and ease to fabricate.
