Abstract
A compact transmitting antenna includes a vacuum tube, a charged particle beam gun, a beam timing controller, and a beam speed controller. The charged particle beam gun is positioned for producing 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. The beam timing controller is arranged to control at least an on time and an off time of the beam. The beam speed controller is arranged to control speed of the beam within the vacuum tube. A frequency modulator is provided by the compact transmitting antenna, arranged to modulate the beam for carrying voice or data signals to transmit information from the compact transmitting antenna.
Claims23
A compact transmitting antenna comprising:
- a vacuum tube;
- a charged particle beam gun positioned for producing a beam bunch of finite length of electrons or ions within the vacuum tube that moves repeatedly and cyclically in its entirety within the vacuum tube at a controlled speed to generate an electromagnetic wave;
- a beam timing controller arranged to control at least an on time and an off time of the beam bunch;
- and
- a beam speed controller arranged to control speed of the beam bunch within the vacuum tube;
- wherein a frequency modulator is provided by the compact transmitting antenna, arranged to modulate the beam bunch for carrying voice or data signals to transmit information from the compact transmitting antenna.
