摘要

本文介绍了一种低剖面宽扫描共形相控阵（CPA），该阵列采用腔背堆叠贴片元件。为了减小阵列轮廓，每个元件都采用了部分介质填充的空腔，为了提高扫描性能，还特意对空腔壁进行了修改。最后，所设计的元件工作频带为 1.45∼1.75 GHz，剖面为 0.086（为 1.75 GHz 时的自由空间波长），在 E/H 平面上实现了 ±60° 扫描，反射系数低于 -7dB。所提出的设计方法和所有数值结果均通过 4 × 4 CPA 原型进行了实验验证。

A Conformal Phased Array with Low Profile and Wide-Scanning Performance for SAR Application

A low-profile wide-scanning conformal phased array (CPA), with cavity-backed stacked patch elements, is presented in this paper. To reduce the array profile, a partially dielectric-filled cavity is employed in each element, and to enhance its scanning performance, the cavity walls are deliberately modified. Finally, the designed element operates in a frequency band of 1.45∼1.75 GHz, with a profile of 0.086 ( is the free-space wavelength at 1.75 GHz), and achieves ±60° scanning in the E/H-planes, with the reflection coefficient below −7 dB. The proposed design method and all numerical results are experimentally verified by a 4 × 4 CPA prototype.
