    摘要： A reconfigurable holographic antenna and a method of shaping an antenna beam pattern of a reconfigurable holographic antenna is disclosed. A baseline holographic pattern is driven onto a reconfigurable layer of the reconfigurable holographic antenna while a feed wave excites the reconfigurable layer. An antenna pattern metric representative of a baseline antenna pattern is received. The baseline antenna pattern is generated by the reconfigurable holographic antenna while the baseline holographic pattern is driven onto the reconfigurable layer. A modified holographic pattern is generated in response to the antenna pattern metric. The modified holographic pattern is driven onto the reconfigurable layer of the reconfigurable holographic antenna to generate an improved antenna pattern.

    摘要翻译： 公开了一种可重构全息天线和一种对可重构全息天线的天线波束图案进行整形的方法。 基线全息图被驱动到可重构全息天线的可重构层上，同时馈送波激发可重构层。 接收表示基线天线方向图的天线方向度量。 基线天线图由可重构的全息天线产生，而基线全息图被驱动到可重构层上。 响应于天线图案度量而产生修改的全息图案。 修改的全息图被驱动到可重构全息天线的可重构层上，以产生改进的天线图案。
