摘要

报道了一种用于有源相控阵的宽带宽、宽波束宽度微带天线元件。该天线单元在h面波束宽度为134°，e面波束宽度为126°时，ku波段的带宽为24.82%，回波损耗优于-10dB。采用不同馈电方式时，天线可分别实现两个正交线极化和一个圆极化。此外，还对该元件组成的8×8阵列的广角扫描特性进行了评价。此外，微带可操纵天线阵列可以很容易地嵌入到可穿戴医疗或商业设备中。

A broad beam-width microstrip cross antenna design for wide scan angle phased array

A wide bandwidth, broad beam-width microstrip antenna element is reported for active phased array application. The antenna element offers a return loss better than -10dB over a bandwidth of 24.82% in Ku-band with beam-widths of 134° in H-plane and 126° in E-plane, respectively. The antenna is capable of realizing two orthogonal linear polarizations and a circular polarization respectively when different feeding approaches are utilized. Moreover, the wide-angle scanning characteristic of the 8×8 array composed of proposed element is evaluated. Besides, the microstrip steerable antenna array can be easily embedded into wearable medical or commercial devices.
