Variable dielectric based antenna with hydraulic knock system

An electronic transmission device transmitting electrical signals, comprising:

• a variable dielectric constant (VDC) plate comprising VDC material sandwiched between a bottom dielectric plate and a top dielectric plate, the VDC material having plurality of orientable domains;
• a common potential plate positioned below the bottom dielectric plate;
• a plurality of delay lines positioned above the top dielectric plate, each delay line transmitting RF signals;
• and
• at least one hydraulic input port enabling injection of VDC fluid into the VDC plate and at least one hydraulic output port enabling ejection of VDC fluid out of the VDC plate.

An antenna, comprising:

• a variable dielectric constant (VDC) plate having an inlet port enabling flow of VDC material into the VDC plate, and an outlet port enabling flow of VDC material out of the VDC plate;
• a plurality of RF radiators arranged as an array above the VDC plate;
• a plurality of delay lines, each coupled to and communicating RF signal with a corresponding one of the plurality of RF radiators;
• an inlet fluid line coupled to the inlet port and an outlet fluid line coupled to the outlet port;
• and,
• a pump maintaining a pressure differential between the inlet fluid line and outlet fluid line.
