dc.description.abstract | New radar architectures employ multiple transmitters
and receivers to enhance their performance, combining wide
and narrow beams to improve the spatial resolution. In this
contribution, two antenna system configurations based on stacked
geodesic lenses are compared. These lenses are fully-metallic
parallel plate waveguides that present very low transmission
losses in the millimetre-wave band. Narrow beams are generated
by a 15-port Luneburg-Rinehart lens with a scanning span
of 50 and 23.4 dBi gain at 77 GHz. For wide beams, two
alternatives are proposed. One alternative is a 3-port defocused
lens antenna with a scanning angle of 50 degree and 14.5 dBi gain.
The second proposal is a 12-port Luneburg-Rinehart lens fed with
1-to-4 power dividers forming a 3-port antenna with a scanning
span of 45.5 and 16.2 dBi gain. | spa |
