Abstract

A novel broadband reflectarray (RA) antenna for 3U CubeSat applications is investigated. A novel frequency selective surface (FSS) in the RA as ground plane for reducing radar cross section (RCS) and signals interference with other communication systems working in other frequency bands is applied. The RA divided to three panels and folded on the sides of the CubeSat to reduce the stowed volume. A novel circular polarization (CP) feed antenna with two stacked patches on two thick substrates with lossy dielectric constant is used to extend the 3dB axial ratio.

新型宽带3U立方体卫星反射天线

研究了一种适用于3U立方体卫星的新型宽带反射天线。提出了一种新型的频率选择面作为地平面，用于减少雷达截面积(RCS)和与其他频段通信系统的信号干扰。RA分为三个面板，并在立方体卫星的侧面折叠，以减少装载体积。采用了一种新型的圆极化馈电天线，该天线在具有损耗介电常数的厚衬底上具有两个堆叠的贴片，从而扩展了3dB轴比。
