基片集成波導的基本概念是利用基片的上下金屬板和兩排間隔一定距離的金屬孔構成波導的金屬壁,由於每排金屬孔孔間距遠小於波長,因此由縫隙泄漏的能量很小,這相當于內部填充了介質的矩形波導,所以能夠用矩形普通波導實現的結構也都可以用基片集成波導來實現,比如功分器、濾波器、天線、耦合器、振蕩器等。Abstract : a new waveguide which can change the wide wall of a rectangular waveguide into a symmetric arc wall is named as a cam - rectangular waveguide. comparing to sectoral waveguide, the new waveguide has the same voltage characteristics and is easier to be produced and fixed. an approximate formula of the dominant mode fields and the normalized conductance of a longitudinal resonant slot cut in the curved wall of a cam - rectangular waveguide are given. a resonant slot linear array in c & x band is designed, in which the slot voltage distribution is equiphase and the input is matched. the input voltage stationary ware ratio and the h - plane pattern of the antenna are measured. the experimental results show the conformance with theoretical results
