cst_pcb_cpw_transition
Create a tapered CPW-to-microstrip transition in CST Studio. Linearly tapers center conductor width and gap over the transition length for impedance matching.
Instructions
Create a coplanar waveguide (CPW) to microstrip transition in CST Studio. Generates a tapered geometry that linearly tapers the center conductor width and gap over the transition length. Calculates CPW and microstrip impedances.
