According to a study from Lisbon, Portugal, "This paper presents a new concept of steerable beam antenna composed by a dielectric lens which pivots in front of a single stationary moderate gain feed. The lens not only allows steering mechanically the beam in elevation and full azimuth, but further increases the gain up to 21 dBi."
"The solution is broad-band, including the entire international unlicensed spectrum from 57 GHz to 66 GHz. A fabricated prototype shows the possibility of tilting the beam from -45 degrees to +45 degrees for all azimuths with gain scan loss below 1.1 dB and radiation efficiency above 95%," wrote J.R. Costa and colleagues.
