Abstract
This electromagnetic delay line is formed by disposing a ground electrode on one surface of a thin dielectric layer and serially connecting main electroconductive strips which are arranged in parallel at certain intervals on the opposite surface of the dielectric layer to form a zigzag strip to face the ground electrode and further, each main electroconductive strip itself is folded to be configured. Accordingly, the negative coupling produced in the zigzag strip is decreased and dispersed as well, thus improving the delay characteristics for the ultra-high frequency signal.
