摘要

本文提出一种新型的特宽带介质波导方向耦合器结构

采用模式叠加理论进行数值分析

并在3mm波段作了实验验证。初步结果表明

理论与实践符合良好。

Abstract

A new structure of dielectric waveguide coupler is described

which has advantages such as very Hat frequency response over 50 percent bandwidth. Theoretical analysis by a superposition of normal modes is presented. Finally

experimental results at 3mm waveband show good agreement with theoretical calculations.
