The paper proposes a high gain, metamaterial based super wideband (SWB) antenna. SWB antenna has two inverted U slots which are responsible for notches at 3.5 GHz and 5.5 frequencies. A flower-shaped slot is etched from the radiator to obtain characteristics. dimensions of 30×35 ×1.5 mm3 with FR4 substrate. frequency bandwidth 3.1 - 15 S11 < -10dB. unit cell designed simulated permittivity perm...
