Abstract

In this letter, a method for the full-wave design of slotted arrays for maximally focused beam with arbitrarily given upper bound constraints on the sidelobes is described and validated. In particular, the pattern synthesis problem is reduced to the solution of a convex programming problem followed by an optimization of the slot positions and/or dimensions, which is obtained by interfacing an in-house developed optimization algorithm with an electromagnetic computer-aided design (CAD). In total, three design examples are reported to show the effectiveness and the generality of the proposed approach; namely, two examples of linearly polarized slotted arrays, designed in standard waveguide and in substrate integrated waveguide (SIW) technology, and a circularly polarized slotted array designed in SIW technology.

任意约束束缝阵列的两步优化全波设计

在这封信函中，描述并验证了具有任意给定旁瓣上界约束的最大聚焦波束的开缝阵列的全波设计方法。特别地，模式综合问题被简化为一个凸规划问题的解，然后是槽位置和/或尺寸的优化，这是通过将内部开发的优化算法与电磁计算机辅助设计（CAD）相结合而获得的。最后，给出了三个设计实例，证明了该方法的有效性和通用性；即采用标准波导和衬底集成波导（SIW）技术设计的线极化开槽阵列和采用SIW技术设计的圆极化开槽阵列。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
