Abstract: New, computationally efficient expressions are developed for input and transfer impedance for cylindrical ports on rectangular power ground planes. The expressions show directly the low-frequency characteristics of the planes. This low-frequency behavior is exploited to obtain computationally efficient expressions for impedance parameters of the capacitor-loaded planes that show directly the characteristics of poles caused by the interactions of the loading capacitors and the planes.
