提出了一种区别于单模(H_(10))的双模脊喇叭天线。可同时给出和及 E面差信息,在带宽为2~2.5倍频程内有稳定的和差方向图和小于3的驻波比,适合于被动制导单脉冲系统应用。对该天线进行了分析,说明了设计原则并附有实例。
A dual mode ridge horn antenna that is different from single mode (H_ (10)) is proposed. Can be given at the same time and E surface difference information, in the bandwidth of 2 ~ 2.5 times the frequency range of the stable and the difference pattern and the VSWR less than 3, suitable for passive guidance single pulse system applications. The antenna was analyzed, illustrating the design principles and accompanying examples.
