摘要
阻抗匹配设计是平板裂缝天线设计中需要重点考虑的问题,主要包含辐射缝和耦合缝两部分的阻抗匹配。文中采用阻抗变换器的理论,将辐射缝匹配和耦合缝匹配设计统一考虑,给出了阻抗匹配的广义匹配方程。运用广义匹配方程可以适当调整辐射缝使之收敛而不需要修改耦合缝的设计参数。
The design of impedance-match is a key problem in the design of slotted-wavegnide array antenna , mainly including the impedance-match of both radiating slot and coupled slot . This paper discusses unified radiating slot matching and coupling slot matching,then establishes a generalized matching equation using the principle of impedance-transform. Through the generalized matching equation we can adjust radiated slots to be convergent and needs not change the coupled slots design parameters.
