Abstract
The electrical length of an antenna element is modified by depositing on a top surface of a voltage variable dielectric a first conductor pattern. The identical conductor pattern is also deposited on a bottom surface of the dielectric layer. The dielectric layer is tunable and the structure is a sandwich with two identical conductors on top and bottom of a tunable dielectric area. The sandwich is created in the same shape as a planar spiral or logarithmic spiral and a DC electric field is applied between the conductors that control the dielectric constant and hence the electrical length of the antenna element.
