antenna current การใช้

This again transfers energy back to the antenna current.
Note that, by the principle of Fourier or Hankel transform relationships between the antenna current distributions and the observed far-field patterns.
This method can be used to compute the radiation resistance for any antenna whose far field radiation pattern has been found in terms of a specific antenna current.
Station officials have confirmed it, as an unusual antenna current meter, one measuring in milli-amps, has been used by current owners to confirm.
That current is in the same absolute direction as the actual antenna if the antenna is vertically oriented ( and thus vertically polarized ) but opposite the actual antenna if the antenna current is horizontal.
