A COMPUTATION METHOD FOR ACTIVE ADMITTANCE OF WAVEGUIDE SLOT IN SIMULATED ARRAY ENVIRONMENT

通过分析、综合关于波导缝隙天线阵的两种常用的综合设计方法（实验测量设计和理论计算设计法）的优缺点，提出了用理论分析计算的方法求解模拟阵列环境中波导缝隙的有源导纳和谐振长度值的设想和具体实现方法。这样既省去了实验测量设计法中测试部件的加工和测量过程，又充分地发挥了理论计算设计法适合于对小型波导缝隙阵进行分析与设计的特点，将会大大地减少波导缝隙天线阵综合设计的工作量。

By analyzing and synthesizing the advantages and disadvantages of the two generally used design methods for slotted waveguide antenna array (the esperimentally measuring method and the theoretically computing method), the idea and practical method are presented in this Paper, that the aetive admittance and the resonant length of waveguide slot in simulated array environment are computed by theoretically analyzing method. Thus, it can not only leave out the machining of the iest components and the procedure of measurement, but also make full use of the characteristic that theoretically computing method is suitable for the analyzing the small slotted waveguide antenna arrays. So the works for design a slotted waveguide antenna array can be reduced greatly.
