Thats a great link...thanks for the information.berkeman said:I googled "capacitor plate antenna" and got several hits. This one has a figure:
I just spoke to another antenna engineer and he set me straight.
My explanation wasnt completely off apparantly, but I was focusing too much on the level portions of the square wave.
During the transient from 0 - 10 volts we get current flow. If we kept the voltage at 10 volts after this we would have an equipotential surface (since the antenna is an open circuit) and the electrons would go back to electrostatic equilibrium and distribute themselves throughout the conductor due to the repulsive forces between them.
But if we continue to alternate the voltage from 0-10 volts and then back to 0 volts then this transient change in voltage will reverse their direction.
For some reason I was applying what happens during the transient portions of the square wave to the "level" portions of the square wave.
I think Im good now.
Thanks for the help berkeman.
