Description
Summary:This paper presents an equivalent circuit model of an octagonal UWB antenna. The UWB antenna is first designed in the electromagnetic simulator, after which the circuit model is developed to match its result. The circuit model utilizes the concept of lumped elements, cascaded in stages, in which each represents the resonant part of the designed antenna element, thus contributing to the resonant frequencies. The antenna is also fabricated and the measured results are similar to that of the simulated results. This antenna also exhibits an impedance bandwidth from 2.7 GHz to 12 GHz, which covers the entire range of UWB characteristics from 3.1 GHz to 10.6 GHz.
