Double Folded Stub Tuner
 |
This example circuit is used in the Sonnet tutorial to teach the basics of creating and analyzing a circuit. It is a simple microstrip double stub tuner. The circuit is composed of a microstrip through line with two quarter-wave stubs placed approximately a quarter wave apart. The stubs have been folded to conserve space. Since Sonnet is a full-wave analysis, the coupling between the line and the stubs, and the effects of the bends are included in the analysis.
