A Spectra Physics Model A supermarket scanner—one of the first ten ever produced. A laser within the unit projects a beam onto a mirror that redirects it through the glass plate on the top. Cade ...

Abstract: Planar end-fire phased array antennas are preferred for their low profile and directional radiation with wide scanning angles. The arrangement of the elements significantly influences their ...

Abstract: A millimeter-wave beam-steerable antenna by controlling the phase difference between the feeding ports is proposed and applied to achieve a wide-angle beam-scanning millimeter-wave phased ...
