摘要

报道了一种采用直接数字制造(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)的原位微点胶相结合。微带线特性分析表明，与线方向平行印刷ABS可使天线的微带馈线损耗最小化。采用多层印刷方法实现了宽带(20%)性能。与现有文献相比，本文提出的天线具有全打印、ku波段工作、高辐射效率(6.5 dB增益)和宽带性能等特点。

Wideband Ku-band antennas using multi-layer direct digital manufacturing

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.
