3D-Fractal Hilbert Antennas Made of Conducting Plates

Abstract

A multiband and wideband 3D-ordinary and reversed fractal Hilbert antennas made of flat conducting plates are introduced. The proposed antennas have acceptable antenna gain. The finite element method (FEM) is used to obtain the radiation characteristics, return loss, input impedance, gain and radiation patterns. The obtained impedance bandwidths cover the required bandwidth of DCS (1710-1880 MHz), PSC (1850-1990 MHz), UMTS (1920-2170MHz) , Bluetooth bands and wireless local area network (WLAN) applications.
