一种可用于复合制导的双频天线

介绍了一种应用于复合制导的双频工作的微带天线。它由一个工作在C波段的十字贴片和在它四周的四个工作在Ku波段的正方形贴片组成。这种结构便于设计并可以印制在一个单层板上。它也可以很方便的组阵，从而满足不同天线的需要。它能被应用于复合制导等一些需要双频工作的天线上。

A Dual-frequency Antenna for Combined Guidance

In this paper, a novel configuration of patch antenna for combined guidance is introduced, which provides a dual-band operation. The structure consists of an S-band crossed patch with four square patches printed in the empty spaces among the arms of the cross. These patches provide a subarray working at X-band. This structure is simple to design and has the advantage that it can be printed on a single-layer. An array geometry designed with the above structure is suggested. It is suitable for satisfying the requirements of a dual-frequency combined guidance antenna.
