Abstract
A system for information transmission having a plasma antenna, including an electrodeless plasma tube, and a power source effective to generate an electromagnetic field to cause ionization of material within the tube so as to form the antenna for one or both of either sending or receiving signals, wherein the electromagnetic field is applied to a portion only of the tube. The system preferably includes a terminal arranged about a base of the tube or establishing the electromagnetic field upon application of power from the power source, to induce surface wave ionization within the tube.
