摘要
介绍了功分器在大功率相控阵馈电网络中的应用,即使用一部发射机通过功分器与天线阵连接进行功率发射,相比传统的一部发射机对应连接天线阵中一副天线的馈电模式,主要有以下优点:天线阵在发射机端口有更好的阻抗特性,改善了原传统模式中由于耦合严重可能导致的个别阵中单元天线阻抗失配严重从而使发射机无法正常工作的问题;可以使天线阵中单元天线的间距有更大的调整空间,使天线阵有更好的扫描特性。
This paper introduces the power dividers in the phased array feed network application, which USES a transmitter power by power splitters connected to the antenna array, compared with the traditional one transmitter corresponding connection in antenna array antenna feed mode, mainly has the following advantages： the impedance of the antenna array in the transmitter port have been better features, improved the original traditional pattern due to the coupling of severe may lead to individual array antenna impedance mismatch in so serious that the transmitter can＇t work normally; can make the antenna array antenna spacing have larger adjustment space, make the antenna array has better scanning features.
