本文介绍了一种采用直接数字制造（DDM）技术的多层、宽带、高效率、微带贴片天线，该天线采用埋腔结构和单片微波集成电路（MMIC）移相器。DDM平台结合了热塑性塑料的熔融沉积成型（FDM）和银纳米粒子油墨的微点胶，实现了具有成本效益的定制多层RF结构。DDM在材料特性、厚度和形状方面提供了设计灵活性，可用于实现高性能天线和阵列。具体地，X波段相控阵天线单元与嵌入腔和MMIC移相器被证明具有81%的辐射效率（不包括IC损耗）和23%的阻抗匹配带宽。
This paper introduces a multilayer, wideband, high-efficiency, patch antenna with embedded cavity and monolithic microwave integrated circuit (MMIC) phase shifter using direct digital manufacturing (DDM). DDM platform combines fused deposition modeling (FDM) of thermoplastics and micro-dispensing of silver nanoparticle inks to realize cost-effective customized multilayer RF structures. DDM offers design flexibilities in terms of material properties, thicknesses, and shapes that can be harnessed to realize high-performance antennas and arrays. Specifically, an X-band phased array antenna element with embedded cavity and MMIC phase shifter is demonstrated with 81% radiation efficiency (excluding IC loss) and 23% impedance matching bandwidth.
