本文提出了一种新型的低成本和高增益的法布里-珀罗谐振器天线（FPRA）在140.0 GHz的增材制造（AM）技术。本设计采用一个简单的2 × 2波导缝隙阵作为馈电天线。在馈电天线上方放置一层部分反射表面（PRS），该部分反射表面由两层金属网格组成，在频率范围内呈现正的反射相位梯度，以改善天线的方向性辐射。为了验证该设计并满足低成本的要求，该天线采用AM技术印刷。与以往的高增益天线相比，由于采用了较少的馈电网络和3D打印技术，我们的设计具有结构简单、成本低的优点。
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 $2\times 2$ 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.
