摘要

A wideband wide-beam dual polarized dipole antenna is proposed in this paper. The antenna has a compact size (0.48 lambda(0 )x0.48 lambda(0) x0.154 lambda(0)) and can operate in a wide frequency range from 1.7GHz to 2.4GHz with a half power beam-width more than 100 degrees in the H-plane for dual polarization. Furthermore, the proposed antenna is employed in two linear arrays. The main beam of the configured arrays can scan from -60 degrees to +60 degrees with a gain fluctuation less than 4dB over the entire band for dual polarization. The antenna is fabricated and measured in an anechoic chamber The measured results have a good agreement with the simulated results.
