摘要：

The distributed coupled line is an important circuit element in microwave circuits and is widely used in filters, impedance transformers, directional couplers, phase shifters, etc. Y-type and Z-type parabolic-taper single-mode transmission lines and their equivalent circuits are first discussed. Then, by superposition of two of the above single modes, the TEM mode along a parabolic-taper coupled transmission line (PTCTL) is analyzed. According to the choice of Y-type or Z-type for tapered single modes and the choice of combinations of balanced-unbalanced modes or open-short line modes as two independent superposed modes, there can be six types of PTCTL. Their equivalent circuits are also easily shown.
