This paper presents a novel low-cost and high-gain fabry-perot resonator antenna (FPRA) at 140.0 GHz with additive manufacturing (AM) technology. A simple 2×2 waveguide slot array is adopted as the feed antenna in this design. A layer of partially reflective surface (PRS), which is composed by two layers of metal grids and exhibits a positive reflection phase gradient over frequency, is placed above the feed antenna to improve the directivity radiation. To validate this design and meet the low-cost requirements, this antenna is printed by AM technique. Compared to previous high gain antennas, our design has the advantage of simple structure and low-cost because of applying fewer feeding networks and adopting 3-D printing technology
