High Gain and Wideband Antenna using Metasurface Horn and Metasurface Superstrate

This paper presents the design of high gain and wideband antenna by using the metasurface horn (MSH) and metasurface superstrate (MSS). Impedance matching bandwidth improves from 2.4% to 11.8% and gain improves from3.5dB to 9.3dB by adding metasurface horn (MSH) and metasurface superstrate (MSS). This technique can be useful for the design of the high gain antennas for the modern communication.
