Numerical analysis of the size effect on a printed 2D-irregular fractal-jet antenna

Abstract

Printed antenna based on 2D-images of a fractal liquid jet has been designed and analyzed numerically. In this work, the effect of the structure's size on the antenna behavior was presented. The return loss, radiation patterns and surface current densities were simulated over the frequency band 1-20 GHz for 3 different sizes of the structure. It is found the size of the fractal antenna affects the antenna radiation properties.
