English Abstract

A gain improved Ultra-wideband (UWB) compact Vivaldi antenna for various applications such as radar and imaging applications with 41×48×1 mm3 size is designed.

A periodic slit on the edges and a polygon-shaped dielectric lens with directors are inserted to the tapered slot Vivaldi antenna to enhance the performances including small size, wide bandwidth, and high gain.

The proposed Vivaldi antenna is executing from (2.7 – 12) GHz bandwidth.

The gain is improved up to 5 dB at the lower range of frequency by clipping slit on the edge of the proposed antenna, however, more than 2 dB is the improvement of the gain at the center frequency.

The proposed Vivaldi antenna shows approximate stable radiation patterns in the frequency range.
