Abstract :
Resonant modes for microstrip devices have been identified with simple temporal poles. Coupling coefficients for the resonant currents have been obtained. Hallen´s integral equation (IE) has been solved to obtain resonant wavenumbers and current distributions. The Hallen IE provides stable, quickly convergent solutions. The frequency dependence of natural-mode currents excited by impressed radiation has been compared with direct frequency-domain solutions to the Hallen equation.<>
