摘要

─研究了一种用于平面波合成的宽带双极化天线近场平面阵列。本文提出了一种工作频率为0.6GHz-3GHz的由84根维瓦尔第天线组成的同心圆阵列PWG。采用约束最小二乘(CLS)算法对阵列元素的权系数进行优化，有效降低了系统不确定性对静区(QZ)纹波的影响。为了降低系统成本和复杂性，每个同心圆环上的阵列单元组成一个子阵列，同一个子阵列的单元采用无源波束形成网络。给出了直径为600 mm的圆形QZ的仿真和初步试验结果。结果表明了设计的可行性。指标项─约束最小二乘(CLS)、平面波合成、宽频带双极化。

Design of an Array-based Plane Wave Generator for Compact Field Antenna Testing

─ A near-field planar array of wideband dual polarized antennas for plane-wave synthesis has been investigated. The paper presents a PWG with a concentric ring array of 84 Vivaldi antennas which can work at 0.6GHz-3GHz. The constraint least square (CLS) algorithm is used to optimize the weight coefficients of the array elements, which effectively reduce the influence of system uncertainty on quiet zone (QZ) ripple. To reduce the system cost and complexity, the array elements in each concentric ring form a sub-array and the elements of the same sub-array adopt a passive beam forming network. The simulation and initial test results of a circular QZ with a diameter of 600 mm are given. The results demonstrate the feasibility of our design. Index Terms ─ Constrained Least Square (CLS), plane wave synthesis, wideband dual polarized.

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
