Abstract
A transmitting antenna includes a first and a second vacuum tube. Each respective vacuum tube includes at least a grounded cathode, a control grid that receives a respective a respective signal, and a plate electron collector. A first spherical ball is connected by a first conducting wire to the plate electron collector of the first vacuum tube. A second spherical ball connected by a second conducting wire to the plate electron collector of the second vacuum tube. Output of the transmitting antenna is produced by an electromagnetic wave that is radiated from conduction current in each of the first and second conducting wires. In another aspect of the invention, first and second spherical balls are connected by conducting wires to the collectors of respective charged particle beam vacuum tubes in which a charged particle beam gun produces a beam of finite length of electrons or ions within the vacuum tube that moves within the vacuum tube at a controlled speed to generate an electromagnetic wave.
