Abstract: A meander-type, frequency-scanned antenna with reduced beam squint suitable for use on an automated vehicle radar system includes a plurality of parallel sub-arrays, each sub-array equipped with a plurality of radiators. The antenna is formed by a serpentine-arrangement of a continuous-strip of material. The serpentine-arrangement configured so a first sub-array characterized by a signal propagating in a first-direction is adjacent to a second sub-array characterized by the signal propagating in a second-direction opposite the first-direction. The first sub-array and the second sub-array are each further configured to define a plurality of radiators configured such that a radar-beam emitted by the antenna in response to the signal is characterized by a direction-angle that is substantially unchanged when a frequency of the signal is varied.
