针对毫米波应用提出了多层介质棒天线（DRA）设计。多层 DRA 由中等介电常数电介质棒芯形成，该芯被低介电常数包层包围，以增加峰值增益。该天线采用两种热塑性塑料的熔融沉积成型 (FDM) 技术制造而成；芯体采用陶瓷复合材料，包层采用丙烯腈丁二烯苯乙烯 (ABS)。天线性能在 30 至 40 GHz 范围内进行测量，并使用数值模拟对结果进行验证。多层天线的峰值增益在整个频率范围内超过 22 dBi。包层对天线性能的影响是将增益提高 3–8.5 dB，同时中心频率处的半功率波束宽度减少 22 度。多层 DRA 设计提供高增益性能、可扩展至其他频率范围以及低成本制造。
A multilayer dielectric rod antenna (DRA) design is proposed for mm-wave applications. The multilayer DRA is formed by a medium permittivity dielectric rod core encased by a low permittivity cladding to increase the peak gain. The antenna is fabricated using fused deposition modeling (FDM) of two thermoplastics; a ceramic composite material for the core and acrylonitrile butadiene styrene (ABS) for the cladding. The antenna performance is measured from 30 to 40 GHz and the results are validated using numerical simulations. The peak gain of the multilayer antenna is over 22 dBi for the entire frequency range. The effect of the cladding on the antenna performance is to increase the gain by 3–8.5 dB, with a reduction in the half power beamwidth of 22 degrees at the center frequency. The multilayer DRA design offers high gain performance, scalability to other frequency ranges and low-cost fabrication.
