ABSTRACT:
This relates to an apparatus for obtaining a specific antenna current or voltage waveshape at an antenna. A reference network, which includes a low level lumped element model of the antenna and the transmitter output network, produces drive signals when impulsed. The first of these signals corresponds to a voltage having the desired antenna current waveshape. The second is a voltage having a waveshape which must be produced across the input terminals of the transmitter output network in order that the specified antenna current be produced. The third signal is a voltage which has a waveshape equivalent to the waveshape of a current which must be injected into the input terminals of the transmitter output network in order that the specified waveshape be produced. At least one of these signals is used to drive the transmitter.
