Abstract
Transverse-folded antennas arrange a radiator, twist reflectors and a transreflector to generate a radar beam without blocking the beam with a feed element. The arrangement provides signal access at an antenna rear face which facilitates integration of the antenna into an automotive radar system. Different embodiments of the antenna collimate the radar beam with curved twist reflectors and with lenses. Scanning is effected with rotatable twist reflectors and with scanning radiators.
