Abstract :
Flat dielectric lens antennas for millimetre-wave beam-steering with fan-beam are studied in this paper. Two different configurations are studied: a dielectric slab waveguide (DSW) lens and a parallel plate waveguide (PPW) lens. Both lenses are made of PREPERM L450 commercial plastic developed for high frequency antenna applications. Two prototype lenses are manufactured and measured at 78.5 GHz. An open-ended WR-10 waveguide is used as a feed. The measurement results are compared to the simulation results performed with Ansys HFSS.
