Electromagnetic delay line

Abstract

Abstract PURPOSE:To improve the delay characteristic such as ultrahigh speed of leading time and improvement of distortion in output waveform by increasing the length of a conductor line in parallel with an imaginary axis line of an electromagnetic delay line more than the distance between adjacent center parts so as to select and adjust simply the optimum coupling state of an inductive element at a high frequency band. CONSTITUTION:An earth electrode 5 is formed on one major plane of a flat, thin and long dielectric plate 4 in a folded conductor line 1 having a rectangular folded form and constituting the inductive element, and also plural capacitive electrode 6 (capacitance C) are formed at a prescribed distance at opposed major planes and the center part of a conductor line 2 is connected to the electrode 6 and placed on the plate 4. The effective length X between the conductor lines 2 in one section is made longer than the center pitch (pitch P) of the adjacent conductor lines 2, the effective length G2 between the adjacent conductor lines 2 in every other section is made shorter than the pitch P, and the relation among them is selected as shown in equation I . It is easy to select the polarity of coupling coefficients a1, a2, positive for the a1, negative for the a2, and also it is easy to make the value of the coupling coefficients closer to an optimum value by selecting properly folded angle or the like.
