A slotline fed gain enhanced ultra wide band radiator having a quarter circular slot is designed and discussed. The -10dB bandwidth of the antenna is found to be 9.2GHz covering a range of frequencies between 2.9 and 12.1 GHz. Proposed structure possess high radiation efficiency of the range of 96% with an enhanced gain in upper frequencies. Polarization of the antenna is found to be linear and is similarly oriented in the entire band. Antenna offers radiation patterns with bore sight oriented in same direction within the range of frequencies of interest. Overall dimension of the antenna is very compact and is 10×24.3×1.6 mm3, when fabricated in FR4 substrate.
