Abstract

A printed wide slot antenna fed by a novel feeding mechanism consisting of a printed bow tie feed placed within the slot aperture and metal baffles between the slot ground plane and a grounded back plane allow this antenna to operate over more than an octave bandwidth with a VSWR<2. Special features of the slot antenna design are its small slot ground plane (1λ₀ ×1λ₀) and small back ground plane (2λ₀×2λ₀). The cross polarisation level of the antenna lies between -22 dB and -36 dB, over the frequency range and the average gain of the antenna is 4.5 dBi
