A laser driven plasma antenna system utilizes a laser having an output for emitting a laser beam that is directed toward and is reflected from the ionosphere so as to produce an ionized column of air extending between the laser and the ionosphere such that electromagnetic radiation is conducted through the ionized column of air as electrical current, and a pulsing circuit for pulsing the laser in accordance with a predetermined pulse rate that corresponds to a particular frequency of interest such that electromagnetic radiation having the particular frequency is conducted through the ionized column as electrical current having a frequency equal to the particular frequency.
