A novel configuration of Slotted Tapered Vivaldi Antenna over 0.8mm FR-4 substrate (61 mm × 48.4 mm) is designed. The antenna is simulated for 2-12 GHz for following configurations: conventional design, etching uniform constant length corrugations, etching double-sided exponentially decaying corrugations in spacing between uniform constant length corrugations, and, employing gratings in bore-sight direction. The measured -10dB bandwidth of antenna is 9.05 GHz that is from 2.95 to12 GHz. The final configuration of antenna provide a unidirectional pattern in the entire band with a maximum realized gain of 10.05 dBi at 8.5 GHz and maximum Front to Back Ratio of 24.67 dB at 4.5 GHz. The fabricated antenna shows flat Group Delay (ns) v/s Frequency (GHz) characteristics with an average value of 2.23 ns. The proposed design is useful for RF applications such as: RFID, radar systems, wideband transmission and reception from 2 to 12 GHz.
