A novel green antenna phase-shift system with data acquisition boards [PDF]
, 2012 A novel green phase shifter system is proposed in this research. The system is developed by a combination of reconfigurable beam steering antennas and data acquisition (DAQ) boards. A combination of two reconfigurable beam steering antennas, located side-

Wearable Fabric Reconfigurable Beam-Steering Antenna for On/Off-Body Communication System
International Journal of Antennas and Propagation, 2015 This paper presents a comparison of on-body performances between omnidirectional (loop antenna) and reconfigurable beam-steering antennas. Both omnidirectional and reconfigurable antennas were manufactured on the same fabric substrate and operated at the

Non-mechanical steering of the optical beam in spectral-domain optical coherence tomography
Scientific ReportsWe demonstrate in a proof-of-concept experiment spectral-domain optical coherence tomography where steering of the optical beam that probes the sample in a transverse scan does not make use of any mechanical element.
