COMPARATIVE ELECTROMAGNETIC AND QUASI-STATIC SIMULATIONS OF A SHORTPULSE PROPAGATION ALONG MICROSTRIP MEANDER DELAY LINES WITH DESIGN CONSTRAINTS

Pavel Orlov – Talgat Gazizov – Aleksander Zabolotsky

   A numerical analysis of microstrip meander delay lines is considered. Results of quasi-static and electromagnetic simulations are given. It is shown that when increasing a number of turns and proportionally reducing their length, distortions of a pulse signal in the line are reduced. At the same time, despite structure's electrical width increase, the agreement between the results of quasi-static and electromagnetic analyses is improved. Thus, it is demonstrated that when designing the microstrip meander delay lines with minimal distortions, the quasi-static analysis is relevant.
