摘要
本文提出了一种新的微带缝隙天线。通过在SIW(Substrate Integrated Waveguide,介质集成波导)一面地板上刻蚀矩形辐射缝隙,利用GCPW(Grounded Coplanar Waveguide)馈电,实现了微带缝隙天线的单向辐射。对比传统的带四分之一波长反射板单向辐射缝隙天线,该天线实现了极低剖面(天线厚度仅为0.0290λ_0)。文章详细分析了该类型天线的辐射原理和天线结构参数对谐振频率的影响。
A novel cavity backed planar slot antenna has been described in this paper. Directional performance is realized on the slot antenna by etching a rectangular slot on the SIW（Substrate Integrated Waveguide） which is feed by GCPW（Grounded Coplanar Waveguide）. Compared with the conventional slot antenna which integrated with a reflector at a quarter wavelength behind, the profile of the proposed antenna is only 0.0290λ0.The radiation principle of the antenna and the influence of antenna structure parameters on resonant frequency are analyzed in detail.
