A low‐profile broadband patch array antenna with a wide scanning range is presented at X‐band. The antenna element consists of the stacked patches, the sheet resistances and the metallic posts with a total thickness of 3.27 mm. The stacked patches are excited by a stripline‐fed aperture with four edge patches surrounding the bottom patch. The sheet resistances and the metallic posts provide a solution to ameliorate the matching responses, besides promoting the scanning angle. The simulated active VSWRs are below 2 and 2.6 as scan ranges ± 60° and ± 70°, respectively, over a bandwidth of 40%. As an example, a prototype array with 8 × 8 elements was fabricated to verify the method. Its measured active VSWRs are lower than 2.4 and 2.9 with the maximum losses of 1.6 dB in the scan angles above.

具有宽带和广角扫描特性的薄型微带贴片阵列

X波段展示了具有宽扫描范围的薄型宽带贴片阵列天线。天线元件由堆叠的贴片，薄层电阻和总厚度为3.27毫米的金属柱组成。带状线进给的光圈将堆叠的色块激发，底部边缘周围有四个边缘色块。薄层电阻和金属接线柱除了提高扫描角度外，还提供了改善匹配响应的解决方案。在40％的带宽上，扫描范围分别为±60°和±70°，模拟的有源VSWR分别低于2和2.6。例如，制造了一个具有8×8元素的原型阵列以验证该方法。其测得的有源VSWR低于2.4和2.9，在上述扫描角度下的最大损耗为1.6 dB。
