摘要

设计紧密耦合偶极子阵列(TCDAs)和连接阵列的一个关键挑战是共模共振，它会极大地影响带宽。本文在TCDA装置设计中采用双偶极子结构，通过将谐振频率移至工作频带以上来解决谐振问题。仿真结果表明，单胞双偶极子结构有效地降低了共模共振，阵列带宽达到3:1 (3GHz ~ 9GHz)。在h面和e面扫描时，阵列的带宽分别为3GHz ~ 9GHz和3.5GHz ~ 9.2GHz，扫描角度可达45°。

A double dipoles per cell structure for solving common-mode resonance in tightly coupled dipole array

A key challenge in designing tightly coupled dipole arrays (TCDAs) and connected arrays is common-mode resonance, which could dramatically influence the bandwidth. In this article, a double dipoles per cell structure is applied in TCDA unit design in order to solve the resonance by moving the resonance frequency above the operation band. The simulation results show that the double dipoles per cell structure reduces the common-mode resonance effectively and the array achieves 3:1 bandwidth (from 3GHz to 9GHz). When scanning in H-plane and E-plane, respectively, the array achieves 3GHz to 9GHz and 3.5GHz to 9.2GHz bandwidth with the scan angle up to 45°.
