Keywords:
Dipole antenna, dual polarization, wideband, wide beam, wide-angle scanningAbstract
A wideband wide-beam dual polarized dipole antenna is proposed in this paper. The antenna has a compact size (0.48λ0×0.48λ0×0.154λ0) and can operate in a wide frequency range from 1.7GHz to 2.4GHz with a half power beam-width more than 100° 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° to +60° 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.
