Evaluation of the Microstrip Lines Connectors in the Meander Delay Line Model
The model of the Meander Microstrip Delay Line (MMDL) evaluating neighbor meander microstrips junction is presented. Model of the MMDL is based on scattering matrix method. Consecutive transition from simplest MMDL model without evaluation of meander microstrip connectors to sophisticated model, which evaluates the meander microstrip connectors by open microstrip line segment. The intermediate models are evaluating the meander microstrip connectors by extending the length of the meander strips and by lumped capacitances. It is found that in case of primitive model calculated MMDL phase delay time usually is lesser than experimentally measured, but in case of sophisticated model, calculated phase delay time rice. This rice depends on the MMDL meander topology and on the technical characteristics of the dielectric substrate. Adequacy of the proposed model was checked by the software written by authors. The carried out calculations have shown good coincidence with the experimentally measured results. Ill. 4, bibl. 16 (in English; summaries in English, Russian and Lithuanian).
