Optical True Time Delay Device for Steering UWB Antenna Arrays -
Based on digital micro-electrical-mechanical mirror array technology (MEMS) and free-space optics, developed by Dr. Betty Lise Anderson PhD, licensed from the Ohio State University, the Buckeye Photonics Optical True Time Delay (OTTD) is extremely compact and low-weight with proven ruggedness for a broad range of commercial applications in cellular and satellite communications.
Phased array antennas (PAA) are replacing traditional physically steered antennas due to recent developments in commercial broadband satellite communications. As demand for stationary and mobile mounted PAA is increasing, antenna makers are struggling to reduce cost and complexity, while increasing bandwidth. DBF promises large (100s of elements) multi-beam arrays, but this promise has been limited by inaccurate beam steering over wide bandwidths and by distortion.
With no tunable lasers, no dispersive elements, and no moving parts required, PAA makers can apply the Buckeye Photonics OTTD technology to eliminate beam squint and steer communication channels with the accuracy required for broadband speeds. For largescale PAA used in both satellite broadband and 5G satellite uplinks, BP’s OTTD removes complexity while increasing beam steering accuracy.
