N2 - This paper presents a novel 3D-printed gradient index (GRIN) lens antenna integrated with a circular polarizer for millimeter-wave applications. The lens, inspired by the Luneburg lens design, incorporates 45°-tilted air gaps to convert linearly polarized (LP) waves into circularly polarized (CP) waves, eliminating the need for complex feed networks or external polarizers. The antenna is side-fed by a WR10 waveguide, achieving a peak gain of 17.6 dBi at 96 GHz and maintaining an axial ratio below 3 dB across a broad bandwidth of 95-109 GHz. Simulations using CST Studio Suite validate the design, demonstrating efficient spherical-to-planar wave transformation and stable radiation patterns. The proposed structure leverages 3D printing to simplify fabrication, offering a compact, highperformance solution for millimeter-wave communication systems requiring circular polarization.
