The optimum feed voltage for a dipole antenna for pulse radiation

The Pulsed-Field Multiport Antenna System Reciprocity Relation and Its Applications—A Time-Domain Approach

“…Observing that the resulting relation has to hold for arbitrary values of and using (8), we end up with (3) in which (12) …”

“…So, for example, Wiener filtering can be applied to minimize the signal distortion due to the presence of noise via the application of the Wiener-Hopf technique [17, p. 397]. Another interesting development is the research into optimizing the transmitted pulse shape of the antenna to given loading conditions, as discussed, for a simple example, in [12].…”

“…Application of (53) to the entire domain exterior to the bounding surface of the Kirchhoff ports yields (12) and (13) with and . In view of the large (cosmic) transmission paths involved, the field values of the impulse-excited sensing fields in the transmission state can, in the radiative cosmos, be replaced by their far-field approximations (see Appendix B).…”

“…In view of the nowadays widespread use of pulsed signal communication (digital and ultrawideband), there is also a growing interest in the pulsed behavior of antenna systems and their transmitting/receiving properties [9]- [11]. An interesting development in this respect is the question of how to determine an 'optimum' pulse shape for the feed in a pulsed-operated antenna system such that at the receiving end a signal of a desired shape presents itself [12]. In all these studies, the time-domain reciprocity of antenna systems plays an instrumental role.…”

Loop-to-loop pulsed electromagnetic field wireless signal transfer

“…In all cases, a change in pulse shape during the transfer takes place, which leads to distortion in the data. Once the geometrical conÀguration has been deÀned, one still has the excitation pulse shape at one's disposal to achieve some optimization in the overall behavior of the system, as anticipated in [6]- [8].…”
