摘要

微带反射天线是一种低轮廓天线，由图1所示的馈源照射的辐射器阵列组成。波束形成技术和性能已经得到了广泛的研究，以改善球面波到平面波的转换，使用可变大小的贴片，例如[1,2]，或短段加载贴片[3]，或在地平面上的可变槽[4]。这些方法基于相同的原理:具有相同反射幅度但反射相位受控的基本天线。受基本天线辐射性能的限制，任何入射和反射配置都可以实现。

Reflectarray with integrated band reject filter for MEMS based beamforming applications

A microstrip reflectarray is a low profile antenna consisting of an array of radiators illuminated by a feed as shown on Fig. 1. Beamforming techniques and performances have been widely studied to improve spherical wave to plane wave transformation using patches of variable sizes for instance [1,2], or stub loaded patches [3], or variable slots in ground plane [4]. These approaches are based on the same principle: having elementary antennas with identical reflection magnitude but controlled reflection phase. Any incident and reflecting configurations can be realized, limited by elementary antenna radiating performances.
