摘要
Ku波段已经成为卫星通信一个主要的工作频段。设计了一种高效率的喇叭天线单元,通过插损较小的空气带状线进行组阵减小阵列厚度;通过180度倒相馈电形式对相邻单元进行馈电,减小了天线极化之间的耦合,改善了天线的交叉极化隔离度性能。结果表明该天线阵列增益效率高,天线整体厚度较小,交叉极化隔离度高,是实现平板阵列天线的理想形式。
Ku bands have become a major work bands in satellite communication.A kind of high efficiency horn antenna is designed,the antenna is fed by air strip line which has the advantage of low insert loss and can reduce the height of the antenna.The adjacent cells are fed by 180 degree phase inversion feeding mode to reduce the coupling between the antenna polarizations which can improve the polarization isolation of the antenna.The result show that the antenna array gain efficiency is high,the overall thickness of the antenna is small,and the polarization isolation is high.It is the ideal form of flat plate array antenna.
