RF Performance Comparisons between Microstrip and Grounded Coplanar Waveguide at mmWave Frequencies

It is common for RF applications using PCB technology at microwave frequencies to use microstrip circuit structures. However, as the frequency increases, at higher microwave frequencies and millimeter-wave (mmWave) frequencies, there are increased RF performance issues for the RF designer to consider. In theory, the Grounded Coplanar Waveguide (GCPW) circuit structure addresses many of the […]
