In this episode of Coonrod’s Corner, John Coonrod compares microstrip and grounded coplanar waveguides at millimeter-wave frequencies. He explains several aspects that can impact these higher frequency applications, including:
• Position of grounding vias used in the grounded coplanar waveguide
• Trapezoidal Effects
• Copper-plating Thickness
• How final plating thickness variation can impact performances on a microstrip and a grounded coplanar waveguide circuit
This video explores many aspects which can be critical for having consistent RF circuit performance at millimeter-wave frequencies and comparing the capabilities and limits of microstrip and grounded coplanar waveguide structures. Measured data is shown and explained in this video, from several different studies, which considers different issues related to circuit design and fabrication.
