Wideband E-shaped dipole antenna with staircase-shaped feeding strip

Abstract

A wideband E-shaped dipole antenna with a staircase-shaped feeding strip is presented. The antenna has wide impedance bandwidth (SWR<1.5) of 60%, which is ranged from 1.84 to 3.44 GHz. Stable unidirectional radiation patterns, low cross-polarisation level and high average gain are achieved over the passband.
