摘要

本文提出了一种结构紧凑(49 × 49 mm2)、高隔离度(32 dB)的宽带双极化天线，采用椭圆型隙结构和改进的y型馈电平衡。偶极子相邻臂间的间隙结构设计为椭圆形，以提高阻抗匹配。进料平衡被修改成与偶极子臂相同的形状，以获得高隔离。该天线在S11 < - 15 dB时实现了1.7-2.7 GHz的宽带阻抗带宽。

Compact Wideband Dual-polarized Antenna with High Isolation using Elliptical-shaped Gap Structure and Modified Y-shaped Feeding Baluns

A compact (49 × 49 mm2) wideband dual-polarized antenna with high isolation (32 dB) using elliptical-shaped gap structure and modified Y-shaped feeding baluns is proposed in this paper. The gap structures between adjacent arms of dipoles are designed in elliptical shape to improve the impedance matching. The feeding baluns are modified into the same shape as the arms of dipoles to obtain high isolation. The proposed antenna realizes a wideband impedance bandwidth covering 1.7–2.7 GHz for S11 <−15 dB.
