Design and Testing of Vivaldi Antenna for UWB Applications
A Vivaldi antenna used for Ultrawideband (UWB) purposes has been proposed in this paper. This design's primary goal is to maximize the bandwidth so as to meet the requirements of a ultrawideband antenna. FR-4 substrate with an epsilon value of 4.3 has been employed to create the proposed antenna and these developments have been simulated. The antenna is energized using a wideband microstrip-to-slot transition feeding mechanism. With physical dimensions of $94.82\ \text{mm} \times 75.00$ mm $\times 1.74$, mm and a working bandwidth of 2.75 to 7.11 GHz for the simulation and 2.4 to 6.5 G Hz for the fabricated antenna, the suggested antenna is also small enough to be easily incorporated into a UWB devices or systems.
