可重构反射阵列设计有贴片元件，可以通过改变贴片的高度来改变反射相位。这些补丁是使用周期性矩模拟方法设计的。包含不同高度元件的反射阵列已经建成并进行了测试。第一个设计是由堆叠贴片组成的 33 元件阵列，工作频率为 7.31 GHz。第二种设计是接地平面上的 120 个元件偶极子阵列，工作频率为 5.2 GHz。微电、机械系统驱动技术可用于实现这些设计，并提出了一个潜在的概念。
Reconfigurable reflectarrays have been designed with patch elements which can vary the reflected phase by varying the height of the patches. These patches have been designed using a periodic method of moments simulation. Reflectarrays incorporating elements of varying heights have been built and tested. The first design is a 33 element array comprised of stacked patches which operates at 7.31 GHz. The second design is a 120-element dipole array over a ground plane which operates at 5.2 GHz. Microelectrical, mechanical systems actuation technology could be used to implement these designs and a potential concept is suggested.
