“…mmWave 대역의 신호는 짧은 파장 길이 때문 에 높은 경로 손실과 낮은 장애물 투과 특성이 있으며, 이 로 인해서 통신 거리가 기존의 통신 기술보다 짧아지는 단점을 가지고 있다. 이러한 단점을 극복하기 위해서 높 은 이득을 가지는 안테나와 빔조향 기술에 관한 연구가 활발히 진행되고 있다 [4]∼ [6] .…”

This paper presents the design and fabrication of an inverted pyramidal graded index (GRIN) lens made from polylactic acid (PLA) material using three-dimensional (3D) printing technology that was integrated with an mmWave-band planar patch antenna. To design a lens structure suitable for the characteristics of the 3D printing process, the lens was divided into 3D cubic voxels. Each voxel utilized the volume ratio of PLA to air to achieve the required effective permittivity, and the lens was designed using refractive index changes according to the effective permittivity. The designed lens had an inverted pyramidal structure and consisted of five vertical layers. The low-cost inverted pyramidal GRIN lens increased the gain of the planar patch antenna operating in the 24∼25 GHz band by 3.8 dBi.
