Abstract

Vivaldi antenna with coplanar stripline feed, exponentially tapered slot, and single layer has been proposed for excellent directivity and high gain. This antenna is suitable for micro-doppler application system. This antenna has been fabricated on 156.02 × 124.91 mm2 FR-4 board with a dielectric constant of 4.4 and height of 1.6 mm. The measured bandwidth corresponding to fraction bandwidth > 15% (good for a minimum resolution of 0.42 m) is 16.02%. The simulation result shows excellent directivity and radiation pattern. This paper also shows the Vivaldi antenna has a gain of 7.95 dB. Details of the antenna for micro-doppler radar application is presented and discussed.
