Impedance matching using 3 parasitic elements

A microstrip circuit is matched by using three parasitic elements, where by "parasitic" we mean that there is no physical connection between the matching elements and the main circuit. A 1:2 microstrip divider is used as an example, for which two parasitic elements are located on the output strips of the divider and a single matching element is located on the input strip. The divider was simulated and measured, showing a very good level of matching quality, as well as very good agreement between simulation and measurement.
