✦ Synopsis
Tke zero-order approximate solution for the currents along thin antennae is used to study the behavior of a received voltage pulse across the terminals of a thin dipole placed at the far zone of a thin transmitting dipole excited by a single-cycle sinusoidal voltage. It is found that each of the four distinct electric field pulses which the transmitting dipole radiates, induces,four distinct (altkougk overlapping) volta,qe pulses at the discontinuities of the receiving dipole antenna. Although the exciting voltage is single-cycle, the time duration of the incident electric field and the induced received voltage is lengthened by 1.5 cycles and up to 2 cycles, respectively. The receiving untenna behaves like an integrating circuit. The spectra of the short-pulse radiatedheld and the received voltage have peuk values at frequencies higher than the carrier.fiequency f, of the exciting single-cycle sinusoidal voltage.
