摘要

本文提出了一种将衬底集成波导(SIW)按顺序旋转排列的介质谐振器天线(DRA)阵列进行集成的方法。所提出的天线结构具有对称、低损耗和紧凑的特点。线极化(LP) DRA元件被用作负载到混合结SIW分路器以产生高纯度的圆极化(CP)辐射。仿真结果表明，在36.50 GHz处，具有极低交叉极化和1db轴比带宽~ 1GHz的对称辐射方向图。

Circularly polarized SIW-integrated DRA for low cost millimeter wave systems

This paper presents a method for the integration of dielectric resonator antenna (DRA) array with substrate integrated waveguide (SIW) arranged in sequential rotation configuration. The proposed antenna structure is symmetric, low loss and compact. Linear-polarized (LP) DRA elements are used as loads to a hybrid junction SIW splitter to generate high purity circular polarized (CP) radiation. The simulation results show a symmetric radiation pattern of very low cross-polarization and 1 dB axial-ratio band width of ~ 1GHz at 36.50 GHz.
