Dynamic Flaps Electronic Scan Antenna
Abstract
A dynamic FLAPS(TM) electronic scan antenna was the focus of this research. The novelty S of this SBIR resides in the use of plasma as the main component of this dynamic X-Band phased S array antenna. The plasma introduces a hysteresis property to the phasing elements thus enabling the elements to be addressed in a row-column configuration; in other words, the system can be configured in a latching configuration. By using stripline technology in conjunction with plasma, a phased-array antenna can be produced at a much lower cost than conventional phased-array antennas. This major cost savings is due to the reduction of required number of drivers (result of the plasma hysteresis property) and the simpler manufacturing process. During the Phase II of this SBIR, the major elements of the plasma phased-array antenna were resolved and demonstrated. These include: 1) The ability of plasma to create an efficient RF wall by de-tuning a passband circuit. 2) The ability of plasma to reflect incident RF with a consistent phase shift. 3) Predictable phase shifting. 4) Near ideal plasma hysteresis signature using proper gas. 5) Integration of the plasma circuit in a stripline configuration using hybrids.
