摘要:
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。
Abstract:
This paper discusses the principle and design of 8mm dielectric integrated antenna with experimental results given. 8mm leaky-wave antennas of the periodic dielectric structures based on the dielectric gratings theory are studied and fabricated. The antenna built on an inverted-strip dielectric waveguide has a planar handy construction, which can easily be mounted on the outer hull of an aircaft or used in light systems. The antenna can be employed as millimeter wave high-gain directional antenna or as frequency-scannable antenna. The half-power beamwidth in the E-plane, gain and side-lobe level were measured to be 5°, 24db and 20db, respectively, when metal flares were attached along both sides of the antenna with optimum angle, the Gain is raised to 27db. The dielectric integrated antenna with circular beam of about 5° is also fabricated. The experimental results agree reasonably well with theoretical predictions
