Abstract :
A coupling between two transmission lines of finite length in arbitrary directions is studied. The transmission line generates electromagnetic fields affecting the other line so that the modified telegrapher´s equation is adopted to analyze the phenomenon. One transmission line of finite length above a ground plane has risers at both line ends. Therefore the fields due to currents on the risers and the line section should be taken account. A four port network expression is obtained from a solution to the modified telegrapher´s equation. Validity of the theory is confirmed by experimental results for various models
