Abstract
An antenna comprising: (a) semi-conductor means ( ) having upper and lower surfaces; the upper and lower surfaces having a pattern of electrically conducting regions; (b) first generating means ( ) for generating conducting plasma filaments of charged carrier between the upper and lower conducting regions; (c) radio frequency feed means ( ) to selected ones of the conducting plasma filaments in order to couple radio frequency energy to or from the semi-conductor means; and (d) second generating means for selectively generating a pattern of conductive filaments between the surfaces of the semi-conductor means in order to reflect and thereby to focus an electromagnetic wavefront incident upon an edge of the semi-conductor means to at least one radio frequency feed point within the semi-conductor means; and the antenna being planar dielectric lens antenna with controlled conductive elements forming a direction antenna for the reception or transmission of a beam frequency energy in the plane of the semi-conductor means.
