This paper presents a new low-cost antenna
intended for moving platforms like planes, high-speed trains or
buses, allowing communications with Ka-band satellites. Beam
scanning capability covers the range from 0° to 65° in elevation
and 360° in azimuth. The antenna structure is composed by a
horn with a 45° slant aperture and a shaped dielectric lens that
tilts and rotates in front of the horn to direct the beam, providing
simple mechanical steering. Scan loss in the elevation plane is of
the order of 3 dB.
