Abstract:
In this paper, a novel broadband high-isolation dual-polarized antenna is proposed for 5G application. The proposed antenna consists of L-shaped elements, Γ-shaped feeding strips, and a box-shaped reflector. The use of simple L-shaped antenna elements not only simplifies the manufacturing process, but also greatly increases the isolation between the two ports. Stable gain and radiation patterns are achieved by using box-shaped reflectors. Results show that an impedance bandwidth of 50.6% for S11 < -10 dB & S22 < -10 dB from 3.1 to 5.2 GHz was achieved, and port to port isolation was higher than 45 dB within the bandwidth. The gains of the measured antenna were 8.7±1.1 dBi in the whole operating frequency band. In addition, stable radiation pattern with low cross polarization, low back radiation was achieved.
