摘要

本文研究了两相互平行的矩形波导离散孔的宽壁耦合。得出了单孔（或孔对）在[u

]频带间的性能极限

最佳耦合平稳度min（△C）和带内最小定向性的最大极限max（Dmin）的数学表述。证明了圆孔不能同时达到这两个极限。文中还给出了最佳单孔（或孔对）的条件式和带宽不等式。

Abstract

In this paper

the coupling between discrete hole on the broad walls of two parallel rectangular waveguides is studied. Optimum characteristic limitation of single hole （or hole-pair） in the [u1

u2] band is obtained: the optimum coupling smoothness ismin the maximum limit of minimum directivity in the band is（dB）It was proved that: the circular holes cannot fulfill the two optimum limits simutaneously. The conditions of optimum single hole （or hole-pair） should beIn general

there exsists the following inequalitywith optimum limit of the bandwidth
