Grid-Oscillator Beam-Steering Array [PDF]
, 1994 Recently Liao and York (see IEEE Trans. Microwave Theory Tech., vol.41, no.10, p.1810, 1993) showed that beam-steering can be achieved by detuning the end elements of a coupled-oscillator array.

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
