Ultra-Wideband Antipodal Vivaldi Antenna for Enhanced Perimeter Surveillances

This study presents the design and simulation of a novel Ultra-Wideband (UWB) Antipodal Vivaldi antenna, optimized for perimeter surveillance applications requiring high range resolution. The proposed antenna operates across an impressive frequency range of 3.09 GHz to over 12 GHz, ensuring seamless coverage and detection capabilities. By leveraging a Rogers RT Duroid 5880 dielectric substrate with a thickness of 1.6 mm, the antenna achieves a remarkable peak realized gain of 10.7 dB at 10 GHz. Simulation results demonstrate a stable end-fire radiation pattern across the entire frequency range, making this antenna an ideal solution for advanced perimeter surveillance applications.
