Abstract :
It is shown that the radiation from a plasma-coated spherical antenna can be enhanced if the antenna is operated at a frequency much lower than the plasma frequency, and if the dimensions of the antenna and the plasma layer are appropriately chosen. This phenomenon may prove useful for overcoming the blackout problem suffered by a reentry vehicle or may offer a novel method of low-loss tuning of a small antenna.
