Abstract


Inhomogeneities of the electromagnetic field are observed at the edges of the electrodynamic delay systems which are designed based on the concept of periodic multiconductor line. The inhomogeneity manifests itself as a non-uniformity of the characteristic impedance and the effective permittivity of the multiconductor line consisting of a finite number of conductors. The influence of non-uniformity of impedance and effective permittivity of the multiconductor microstrip line on the frequency responses and characteristics of meander delay lines is studied in this paper. It is shown that matching characteristic impedance and effective permittivity of the multiconductor line the bandwidth of the delay line can be extended and delay time increased preserving its dimensions.
