Comparison of characteristics of discontinuities in the form of high-impedance section of microstrip line and a section with slot resonator in grounding plane

Abstract

In this paper, characteristics of short high-impedance (inductive) microstrip line sections embedded into base transmission line and wider sections with rectangular slot resonator in ground plane are considered and compared. Research has shown that it is possible to obtain characteristics similar to circuit with conventional, but often technically non-realizable high-impedance section line, by varying the section length and size of narrow rectangular slot resonator in defined frequency range.
