Abstract:In this paper, a miniaturized millimeter-wave (mm-wave) antipodal Vivaldi antenna (AVA) is proposed. The AVA antenna structure is modeled using MWSCST2022 optimization tools. The AVA exhibits good impedance matching, high gain, and a small optimum size of 5 × 2.5 × 1.5 mm 3 , fabricated on an FR-4 substrate. An array of square and circular director units is modeled and loaded at the front and back of the AVA antenna. The spacing between directors is studied and positioned at a tuned distance from the antenna f… Show more
