Abstract:
1. Apparatus for transmitting information by means of radiated electromagnetic fields in free space for reception of the information by a receiver at a remote location, the apparatus comprising an antenna in the form of a super-toroidal conductor having a conductor length l, an electrical signal generator controllable to produce electrical signals having at least one frequency component which is not less than 2 c/l where c is the speed of light in free space, a modulator to modulate said electric signals in accordance with the information to be transmitted, a coupler to couple said modulated electrical signals from said generator to energize said antenna at the frequency of said component which is substantially above frequencies at which the current in all segments of the super-toroidal conductor can be in phase, whereby electromagnetic fields are launched by the antenna to transmit the information.
