A CPW Fed Metasurface MultiBand Antenna with Aperture Coupling: A CPW Fed Multi Band Antenna

Abstract

This paper presents an annular ring Metasurface (MTS) Patch antenna with multi band characteristics. The geometry of the antenna is $0.42\lambda_{0}\times 0.42\lambda_{0}\times 0.02\lambda_{0}$ (where $\lambda_{0}$ is the lower resonating frequency i.e.2.42GHz). An aperture coupling through CPW is used to feed the uniform MTS radiating structure to resonate at multiple frequencies 2.42GHz, 2.86GHz, 6.3GHz, 6.94GHz and 7.96GHz. It is observed to have a good bandwidth and higher gain values at the targeted frequencies with the maximum gain of 9.81dB and thus used in WLAN, C band applications like weather radar systems and satellite communications
