Low-Cost 3D Printed Dielectric Lens Antennas for 5.9 GHz Frequency Band V2X Applications

In this paper a selection of designs of directional lens antennas for V2X communication is presented and investigated. We have compared five different types of all-dielectric 3D-printed lenses - extended hemispherical, ellipsoidal, zoned cylindrical, planar graded index, and modified Luneburg lens, all of them using the same patch radiator. The assumed fabrication method for all lenses is 3D printing using low-cost PLA filament. The antennas with the most promising simulated performance and lens constructions were fabricated and measured.
