Abstract:

The basic theory and equations have been derived to describe the radiation characteristics of a wideband CW or pulsed antenna from measured near-field data and to describe the electromagnetic coupling characteristics of a near-field, cosited pair of wideband CW or pulsed antennas. The theory and equations are applicable for both in-band and out-of-band situations and for stochastic as well as deterministic processes. Numerical simulations have been conducted to validate the analytical results and gain insight into the general behavior of the radiation and coupling characteristics of CW antennas. Author
