本文为平面裂缝阵列天线常用的一种耦合机构提出了有效的计算方法。阐述了耦合原理,分析了等效电路并求得了耦合裂缝的规一化电导和耦合系数。以实现需要的天线口径激励。经过S波段、C波段和X波段的实践工作证明:只要在理论计算的基础上,通过所述实验手段进行一次循环修正,则可获得满意的结果。此外,这种分析方法也同样适用于谐振裂缝的其它双波导耦合机构。
This paper presents an effective calculation method for a coupling mechanism commonly used in planar crack array antennas. The coupling principle is expounded, the equivalent circuit is analyzed and the normalized conductance and coupling coefficient of the coupling crack are obtained. In order to achieve the required antenna caliber incentives. After S-band, C-band and X-band practice proved that: as long as the theoretical calculations based on the experimental means by a loop correction, you can get satisfactory results. In addition, this method of analysis is equally applicable to other dual-waveguide coupling mechanisms that resonate cracks.
