Single fed UWB sierpinski fractal monopole antenna array

Abstract

In this work, single fed uniformly spaced seven elements mod-3 Sierpinski gasket antenna array is designed using CST MWS (Computer Simulation Technology Microwave Studio). The designed antenna array is fed by an N type connector. S parameter, far field, E-field, and surface current results are analyzed. The simulation results show that more than 89% total efficiency and 3 dB minimum realized gain are achieved in 500 MHz - 1100 MHz band within -10 dB return loss. The results show that the proposed antenna array is suitable for wide band and high power applications. © 2019 IEEE.
