宽带宽角扫描双极化阵列天线设计

摘要

设计了一种宽带宽角扫描双极化vivaldi阵列天线。通过微带线向槽线耦合馈电，设计了工作于1～6GHz的vivaldi双极化天线阵，并对加工的实物进行了测试。阵中单元驻波小于1．5，天线阵两维扫描角度达到±60°。试验结果表明，该天线在电子对抗、宽带通信等领域具有很大的应用价值。%The design of a wideband dual-polarized wide-angle scan vivaldi array antenna is made. With the slot line coupled through the microstrip, a dual-polarized vivaldi antenna array working at 1 - 6GHz is designed. Besides, the array is machined and tested with the VSWRs of the elements less than 1.5 and the 2D scan angle up to ± 60°, which indicate that the antenna is of great application value in the ECM and the wideband communication, etc.
