An Antipodal Vivaldi Antenna Using Radiant Side Slot Edge Based on the Star Trek Dominion Insignia

This paper presents the Vivaldi Antipodal Antenna (AVA) development using radiant side slot edges based on the Dominion breed insignia from the Star Trek TV series. The intention is that the proposed antenna, with radiant cavities called Gamma-AVA, improves the gain, decreases the Side Lobe Level (SLL), and eliminates squint, where the peak gain in the radiation pattern at a given frequency is at 0 degrees. After performing the simulation, using Ansys HFSS 2021 R1, and measuring parameter S 11 , with NanoVNA V2 of conventional AVA and Gamma-AVA, the goal was achieved by the proposed antenna resulting in a gain of 9.53 dB, with SLL of -9.99dB and 0.000 squint, having, therefore, a performance superior to that of the AVA.
