Retired Work: PARCA Software Defined Antenna™ packs more antenna capability into less footprint.
Syntonics’ Pixel-Addressable Reconfigurable Conformal Antenna (PARCA) Software-Defined Antenna™ is a conformal, reconfigurable, electronically pointed phased array antenna technology that can support SATCOM, EW, SIGINT and COMINT applications up to 44 GHz.



parcaPARCA uses pixel-by-pixel physical reconfiguration of microstrip feed-lines and radiating structures to provide antenna capabilities such as beam steering, beam shaping, operation at multiple frequencies and polarizations, and connections for multiple radios using a single reconfigurable antenna structure. Reconfiguration occurs rapidly (approximately one millisecond) and high RF power levels can be handled.

Antenna elements and transmission lines are configured, reconfigured, tuned, and steered as needed under microprocessor control. Thus, a PARCA aperture can be shared between applications with different antenna requirements.

A PARCA antenna is composed of adjacent PARCA tiles and multiple tiles create an piece-wise conformal aperture of any size. PARCA tiles are fabricated using conventional MEMS and semiconductor techniques. Each tile has two layers of electronic circuitry and one layer with ~10,000 MEMS pixels and actuators.
