A new compact dual-polarized co-axial full-band antenna for 2G/3G/LTE base station applications

Abstract

A new compact dual polarized co-axial antenna with gain greater than 8.0dBi is presented operated in 0.69GHz–0.96GHz/1.71GHz–2.69GHz. The size of the antenna is 286 × 286 × 81mm³. Its reflection coefficient and the cross-polarization isolation are less than −10.5dB (−12dB) and higher than 15dB (20dB) in low (high) frequency respectively. Measured results are agree well with the simulated one, verifying the availability of this antenna design.
