据报道，采用直接数字制造 (DDM) 方法制造的全印刷 Ku 波段孔径耦合贴片天线的设计和性能，该方法将丙烯腈丁二烯苯乙烯 (ABS) 热塑性塑料的熔融沉积与导电银浆 (CB028) 的原位微分配相结合。微带线特性表明，通过与线路方向平行印刷 ABS，可以最大限度地减少天线的微带线馈电损耗。通过采用多层印刷方法可实现宽带 (20%) 性能。与文献中的现有工作相比，所提出的天线脱颖而出，因为它是完全印刷的，在 Ku 频段内工作，并表现出高辐射效率（6.5 dB 增益）和宽带宽性能。
Design and performance of a fully-printed Ku-band aperture coupled patch antenna manufactured by making use of a direct digital manufacturing (DDM) approach that integrates fused deposition of acrylonitrile butadiene styrene (ABS) thermoplastics with in-situ micro-dispensing of conductive silver paste (CB028) is reported. Microstrip line characterizations demonstrate that the microstrip line feed loss of the antenna is minimized by printing ABS in parallel with the line directions. A wideband (20%) performance is achieved by employing a multilayer printing approach. Compared to existing work in literature, the presented antenna stands out as being fully-printed, operating within the Ku-band, and exhibiting high radiation efficiency (6.5 dB gain) with wide bandwidth performance.
