两个正交矩形波导斜缝耦合特性的研究

 本文用矩量法讨论两个正交矩形波导宽边上中心窄斜缝的耦合特性问题。考虑到波导壁的厚度,求解缝隙上、下表面的切向电场,计算了缝隙口径上切向电场分布、散射场和散射参量,以及等效串联阻抗等重要参数。理论计算和实验结果吻合良好。

STUDIES OF COUPLING PROPERTIES OF AN INCLINED SLOT IN TWO CROS SED RECTANGULAR WAVEGUIDES

The coupling properties of an inclined narrow slot on the center lines of the broad walls between two crossed rectangular waveguides are discussed by means of the moment method. The tangential electric fields on the upper and the lower surfaces of the slot are mathematically solved with taking into account the waveguide wall thickness. Some computed curves of the important parameters of the slot, such as the tangential electric field distribution on the surfaces, the scattering fields, the scattering parameters, and the equivalent series impedance, are given. The theoritical and experimental results are in good agreement, '
