本文讨论了8mm介质集成天线的原理和设计,并给出了实验结果。 8mm周期介质结构的漏波天线是根据介质光栅理论研制的。它以倒置介质带状波导为基体,平面结构轻巧,适合装在飞行器的外表面及轻便系统中使用。它可用作毫米波高增益的定向天线亦可用作宽频带的波束扫描天线。研制成的天线E面已经达列5°的窄波束,24db的增益和20db的旁瓣电平。附加一对尺寸不大的金属反射板后已可得到27db的增益。5°左右的圆锥波束介质集成天线也已制成。对研制天线的实测结果与理论计算基本一致。
This paper discusses the principle and design of 8mm media integrated antenna, and gives the experimental results. The leaky wave antenna of 8mm periodic medium structure was developed according to the theory of dielectric grating. It is based on the inverted dielectric ribbon waveguide, the plane structure of light, suitable for installation on the outer surface of the aircraft and light system. It can be used as a directional antenna with high gain in millimeter-wave and as a broadband beam-scanning antenna. Developed antenna E surface has reached a 5 ° narrow beam, 24db gain and 20db sidelobes level. Additional pair of small size metal reflector has been gain of 27db. Cone beam dielectric integrated antennas of about 5 ° have also been made. The measured results of the antenna is basically the same as the theoretical calculation.
