Abstract

A wideband unidirectional antenna composed of a planar dipole and a shorted patch antenna is presented. The antenna is excited by a E-shaped strip feed line. A wide impedance bandwidth of 43.8% (SWRles1.5) from the frequency of 1.85 to 2.89 GHz is achieved. Stable radiation pattern with low cross-polarization, low backlobe radiation, nearly identical E-and H-plane patterns and an antenna gain of ~8dBi is found across the entire operating bandwidth.
