摘要
到目前为止,许多工作都集中在从米到毫米波频段的相控阵天线(PAAs)的设计上。随着PAAs的快速发展,对其宽带广角扫描性能提出了迫切的要求。当然,宽带广角扫描PAAs的设计是一个重要的发展趋势,但事实上,PAAs的扫描角度受到许多因素的限制,其中最主要的是PAA元件之间的相互耦合。为了解决这一问题,本文研究了具有广角扫描性能的长缝隙PAA。该天线元件是基于J. J. Lee的长缝隙天线理论,在J. J. Lee的理论中,长缝隙天线具有良好的宽带性能,但广角扫描性能有待提高。为了实现广角扫描性能,该元件采用两个短脚来控制天线单元之间的相互耦合。同时,在天线上放置两个基片作为广角阻抗匹配(WAIM)层。仿真结果表明,所设计的阵列在X波段具有极好的广角扫描性能。在E平面,在6.2 ~ 13.2 GHz(72%带宽)±60°范围内扫描时,VSWR≤2.5;在H平面,VSWR≤2。5扫描到±60°从7.6到12.7 GHz(50%带宽)。在未来的工作中,将制作一个初始原型阵列来验证所提出的概念。
Wide-angle Scanning Phased Array Based on Long Slot Antenna
Much work so far has focused on the design of the phased array antennas (PAAs), across the frequency ranges from the meters to millimeter-wave bands. With the rapid development of PAAs, there is an urgent demand for wideband and wide-angle scanning performance. Naturally, the design of wideband and wide-angle scanning PAAs has been an important development trend, but as a matter of fact, the scanning angle of the PAAs is limited by many factors, among these factors, the major one is the mutual coupling between the PAA elements. To solve this problem, a long slot PAA with wide-angle scanning performance is investigated in this paper. This antenna element is based on the J. J. Lee’s theory of the long slot antenna, in J. J. Lee’s theory, the long slot antenna has a good wideband performance, but the wide-angle scanning performance need to be improved. In order to realize the wide-angle scanning performance, the proposed element uses two shorting pins to control the mutual coupling between the antenna unit cells. Meanwhile, two substrates, severing as the wide-angle impedance matching (WAIM) layers, are placed upon the antenna. Simulated results show that the designed array has an extremely good wide-angle scanning performance in X band. In E plane, the VSWR ≤ 2.5 while scanning to ±60° from 6.2 to 13.2 GHz (72% bandwidth), In H plane, the VSWR 2≤.5 while scanning to ±60° from 7.6 to 12.7 GHz (50% bandwidth). In the future work, an initial prototype array will be fabricated to validate the proposed concept.
