Theoretical solutions of transient radiation from traveling-wave linear antennas

Analytic expressions based on time-domain integral equations for the electric and magnetic field intensities are developed for linear antennas of finite length. With the help of Fourier transformation and successive partial integrations, explicit closed-form expressions for the transient radiation are obtained. There are no restrictions on the waveform of the current along the antennas, the length of antennas, and the position of observations. The method can also be adopted to solve for the transient radiations due to reflected traveling-wave currents along the antennas, with similar results.<
