Abstract:
A novel wideband dual-polarized antenna is presented for 2G/3G/LTE base-station applications. The proposed antenna consists of two orthogonal modified bowtie dipoles, parasitic elements and a cavity. By using parasitic elements and compact cavity, the antenna achieves a wide impedance bandwidth about 77.3% (VSWR<1.5) for both ports. Both simulated and measured results show that the proposed antenna has a port isolation higher than 31 dB and high gain (>8.5 dBi) over the entire operating band. Moreover, good cross-polarization (>25 dB) performance and a front-to-back ratio better than 20 dB are also verified by measured results.
