Abstract

A compact dual-band dual-polarized antenna is proposed in this paper. The two pair dipoles with strong end coupling are used for the lower frequency band, and cross-placed patch dipoles are used for the upper frequency band. Breaches are introduced at the ends of the dipoles of the upper band, which can benefit the compactness and bandwidth of the antenna. The ends of the dipoles for upper frequency band are cut off a corner, which also benefit the compactness and matching of the antenna. An antenna prototype was fabricated and measured. The measured results show that the antenna can cover from 790 MHz to 960 MHz (19.4%) for lower band and from 1710 MHz to 2170 MHz (23.7%) for upper band with VSWR<1.5. It is expected to be a good candidate design for base station antennas.
