Abstract: A compact form of ultra-wideband antenna with C-shaped split ring resonator is proposed, it has a band-notched characteristics. This antenna consists of a rectangular patch with C-shaped split ring nature. The proposed antenna is resonating from 2.8-10 GHz with VSWR < 2. The circle fashioned slit is imprinted in the emit patch. The main principle of this work is to achieve higher gain for UBW frequencies range except the stop bands. At 3.6 GHz, 5.7 GHz and 8 GHz frequencies, the suggested antenna approximately exhibits the omni-directional emission pattern in the plane of H. In order to get the stable radiation pattern characteristics throughout the entire bandwidth, S₁₁ loss of the respective antenna should be less than -10 dB. The suggested antenna is successfully simulated and observed at various required specifications such as radiation pattern, S₁₁ loss, gain with the aid of HFSS software. We promised that the recommended antenna is suitable for Wi-MAX/WLAN and satellite applications.
