Current distribution in antenna
WebAbstract: A simple formula is given for the approximate total current distribution on the electrically thick short tubular transmitting antenna driven by a delta-function source. Published in: IEEE Transactions on Antennas and Propagation ( Volume: 22 , Issue: 5 , September 1974 ) WebThe electric field between the ends of the antenna is maximum when the current has stopped. The current in the arms is maximum when the charge is all gone, so there is no voltage across the capacitor.
