Variable dielectric based antenna with improved response time
Natural response time for domains to assume their natural relaxed state is accelerated by forcing the domains to assume the natural state. The forcing may be done by application of electric field, magnetic field, or application of mechanical, hydraulic or sonic pressure. Additionally, an RF choke and/or one or more RF traps, are incorporated in the structure. When the forcing is implemented via electric field, the control signals may be applied onto the transmission lines and to at least one control line flanking each of the signal lines.
