Abstract
An ultra-wideband dual-polarized antenna with a low profile is proposed for base-station applications. The dual-polarized antenna consists of two crossed dipoles, a square patch, and a square meta-surface. The ultra-wideband operation is achieved by the coupling between the crossed dipoles and the square patch which creates multiple resonances. The square meta-surface is introduced atop the antenna to improve the impedance matching. It is shown by simulation and experiment that the dual-polarized antenna achieves an impedance bandwidth of 76.5% over 2.3 to 5.15 GHz for voltage standing wave ratio (VSWR)<1.5, covering the frequency bands for long term evolution LTE-2300/2500 and 5G new radio (NR) sub-6G n7/n38/n41/ n77/n78/n79 systems. The ultra-wideband antenna features stable radiation patterns with a gain of 8.5 ± 0.5 dBi and a half-power beam width (HPBW) of 65° ± 5°.
