【摘要】 Ku波段或更高频段动中通、高速率卫星通信已经成为一个主要的应用领域。低剖面动中通天线装车高度低,风阻小,隐蔽性好等优点,能够满足车载卫星天线的迫切要求。根据车载天线低剖面的新要求,研制了一种高性能、小型化Ku波段双极化工作的低剖面阵列动中通天线,该天线采用低损耗波导阵列的组阵方式,天线阵列设计为4∶1长条结构,应用了相控电子波束扫描跟踪技术,具有跟踪方式简单,天线效率高等特点。测试结果表明天线性能优良。更多还原

【Abstract】 High data rate communications on the move with Ku and higher frequency bands is becoming a major application area for satellite communications systems.The antenna designed has the advantage of low profile,small air drag force and more hidden which can meet the urgent need of vehicular satcom antenna.A high performance and low profile antenna of "Satcom on the Move" with dual polarization using Ku band is introduced.The antenna is designed in the shape of a four-to-one rectangle.The method of beam scanning tracking is used which is simple and efficient.The test results show that the antenna has a high performance on the pattern and tracking performance.更多还原
