Design the Quarter-wave transformer for impedance matching applications by using the pcbComponent, microstripLine, and traceRectangular object in the RF PCB Toolbox.

Create a pair of close traces using traceLine object and performs analysis on those traces to calculate the amount of unwanted coupling to the passive trace.

Use the custom traces traceLine and tracePoint in RF PCB Toolbox and create PCB traces with different shapes and orientations. The traceLine uses the lengths and angles properties to create a trace and the tracePoint uses points to create the trace. For both the traces, corner property can be set to Sharp, Miter, and Smooth to create specific corners at all the bends.
