Abstract :
A novel wideband printed dipole antenna suitable for wireless mesh network (WMN) application is proposed in this paper, with VSWR<1.6´s bandwidth greater than 31% at 5.5GHz, covering the WLAN upper band. When arranging the dipoles for an E-plane array, two parasitic elements are utilized on both sides of the array to achieve a 25-degree beamwidth in the E-plane so that the array could deal with rugged road surfaces, and to maintain high gain as well. Both simulation and experimental results are presented, and the relationship between parasitic elements and the array performance is also investigated.
