Microstrip fed star super wideband fractal antenna

Abstract

A microstrip line fed star fractal antenna for super wideband applications is presented. Second iterative star shaped fractal geometry of the radiator, modified feedline and notch loaded semi-elliptical ground plane are used to achieve an impedance bandwidth of 4.6-52 GHz. A good agreement is observed between the simulated and experimental results. It has an overall volume of 19.7×19×1.6 mm3. It has advantages of miniaturized dimensions and wider bandwidth over previously reported structures. © 2016 IEEE.
