Double Slot Antipodal Vivaldi Structure for Ultrawideband Applications

Abstract

This study discusses the development of a Conventional Antipodal Vivaldi Antenna (CAVA), which is intended for use in ultra-wideband applications. The development is carried out by adding a Double Slot Structure (DSA VA) with Corrugated Edges (CE) and a Trapezium Dielectric Director (TD). The antenna is targeted to work in the 3.5 GHz - 10.5 GHz frequency range. Based on the test results, it is found that there is an increase in performance in the operating frequency range with gain variations between 10–14 dBi. The method can also improve the characteristics of the antenna radiation pattern at high frequencies in the E-Field field.
