A gas plasma antenna with a rigid, flexible or semi-flexible substrate and an improved method of generating a uniform electron density. The antenna comprises a plasma display panel (PDP) containing a multiplicity of Plasma-tubes, each Plasma-tube containing a gas, which is ionized to produce electron density. A selected portion of each Plasma-tube acts alone or in concert with a selected portion of other Plasma-tubes to form a dipole or pattern of dipoles.
