Abstract
A novel technique-Volterra series analysis-is applied to the analysis of a nonlinearly loaded antenna. The electromagnetic field problem is first reduced to a network problem by application of the method of moments. The nonlinear network problem is then solved using the Volterra technique. A procedure with sinusoidal inputs for obtaining a time domain solution from the frequency domain solution without using fast Fourier transform techniques is demonstrated. Thei-vcharacteristic of the nonlinear load is approximated from scattered power measurements. The derivedi-vcharacteristic is then used to predict scattered power levels at different intermodulation responses of the loaded antenna.Keywords
