摘要

提出了一种简化的双极化阵列单面封装微带线馈电网络。MSL耦合到天线元件的交叉槽孔径上。设计了具有两种不同馈线的双极化磁电偶极子。设计了一种ka波段4 × 4双极化阵列。该阵列增益大于16 dBi，端口隔离优于30 dB，交叉极化优于-20 dB，带宽为20%。所提出的馈电方案适用于任何双极化阵列尺寸。

Printed Feed Network on a Single Surface for Dual Polarized Antenna Array

A simplified packaged microstrip line (MSL) feeding network on a single surface for a dual-polarized array is presented. The MSL couples to a cross-slot-aperture of the antenna elements. A dual-polarized magneto-electric dipole is designed with two different types of feedlines. A Ka-band 4 × 4 dual-polarized array is designed. The array has better than 16 dBi gain with port isolation better than 30 dB and cross-polarization better that -20 dB within a 20% bandwidth. The presented feed scheme is valid for any dual-polarized array size.
