| The use of the basic large-current radiator—discussed
in a previous paper—and the Hertzian
electric dipole as sensor is investigated. If the sensor works into a large
resistive load, typically implemented by an emitter follower, its output
voltage varies like the electric field strength, while a capacitive load
produces an output voltage proportionate to the integral of the field strength.
The maximum energy is transferred to a load impedance that is equal to
the radiation resistance of the antenna. This is the same result as in
the case of sinusoidal waves, but the radiation resistance for nonsinusoidal
waves differs from that for sinusoidal waves. An effective aperture can
be defined, which is again analogous, but not equal, to the same concept
used for sinusoidal waves. 9 pages. |
