Abstract

In this letter, we introduce a new parasitic antenna array with a 360deg switchable coverage in the azimuthal plane. Unlike most switched parasitic arrays which are narrowband or at most dual band, this array covers an octave bandwidth. The frequency band of interest in this letter is the UHF band, particularly the 225-450 MHz tactical communication band. The array consists of a driven element surrounded by two layers of parasitic elements. The driven element is a wire frame biconical antenna and the parasitic elements are V-shaped bent wires. The proof-of-concept was simulated using FEKO method of moments (MoM) package and further verified using Ansoft HFSS. Simulation results show that the antenna gain is 6-10 dBi over an octave bandwidth
