提出了一种新型的机载双频双极化阵列天线。集成了两个薄衬底（R/T Duroid 5880衬底，epsivr = 2.2，厚度为0.13 mm）的平面阵列，可在S频段（3 GHz）和X频段（10 GHz）同时工作。每个3ghz天线单元是一个大型矩形环形谐振器天线，其增益为9.5 dBi，比普通环形天线的增益高约3db。10ghz天线单元为圆形贴片。它们组合成增益为18.3 dBi的阵列，采用串联馈电结构，节省馈线网络空间。超薄阵列可以很容易地放置在飞机的机身上，由于其重量轻和保形结构。它将用于无线通信、雷达、遥感和监视应用。
A new dual-frequency dual-polarized array antenna for airborne applications is presented in this paper. Two planar arrays with thin substrates (R/T Duroid 5880 substrate, with epsivr = 2.2 and a thickness of 0.13 mm) are integrated to provide simultaneous operation at S band (3 GHz) and X band (10 GHz). Each 3 GHz antenna element is a large rectangular ring-resonator antenna, and has a 9.5 dBi gain that is about 3 dB higher than the gain of an ordinary ring antenna. The 10 GHz antenna elements are circular patches. They are combined to form the array with a gain of 18.3 dBi, using a series-fed structure to save the space of the feeding line network. The ultra-thin array can be easily placed on an aircraft's fuselage, due to its lightweight and conformal structure. It will be useful for wireless communication, radar, remote sensing, and surveillance applications.
