A Vivaldi antenna with three techniques to enhance the radiation properties is introduced. The first technique is the insertion of an elliptical patch parasitic radiating element in the Vivaldi aperture to enhance the coupling between arms and to produce strong radiation in the end fire direction. The second technique is the addition of corrugation at the antenna edge to improve the antenna characteristics. The third technique is insertion of planar reflector at the backend of the antenna that enhance the front-to-back (F/B) ratio to a great extent. The antenna is designed using standard 0.18 μm six metal layer CMOS technology. The overall size of the antenna on chip (AOC) is 500 umx870 um. The proposed antenna reveals end-fire radiation pattern with 0.7 dBi simulated average gain and 37% simulated radiation efficiency
