Abstract

A rigorous analysis of hexagonal slot with electromagnetically coupled parasitic element is presented in this article. The wide band feature of the antenna highly depends on the shape and location of the parasitic element and tuning stub. It is found that tuning and overlapping of resonating modes at lower frequency band are mainly achieved by parasitic element. The proposed antenna exhibits the bandwidth of 120.83% from 1.45 to 5.8 GHz for S₁₁<-10 dB. The parameters of the antenna and circuit model are studied. The role of individual resonators in circuit modeling is also explained. Series of equations for lower cutoff frequency and other resonating frequencies are deduced after inspecting the surface current distribution. At frequencies 2.27, 4.17, and 5.2 GHz, the simulated and measured far fields are compared.
