Abstract

This paper deals with the design and experimental characterization of wideband discone antenna made of polylactid-acid (PLA) material using a three-dimensional (3D) printing technology. The proposed antenna is intended to have a wideband operating frequency of 700 MHz–6 GHz desirable for electromagnetic interference (EMI) sensors application. Here, the use of 3D printing technology is to realize the cone of the antenna, while the disc is implemented using a copper-sheet. To demonstrate feasibility of the proposed antenna, a conventional discone antenna made of all copper-sheets is also realized and experimentally characterized as comparison. From the characterization result, it shows that the proposed 3D-printed discone antenna has the –10 dB operating bandwidth range of more than 5.3 GHz from the frequency of 698 MHz. This measured operating bandwidth showed obviously wideband characteristics and was wider than the one of conventional discone antenna.

基于pla的宽带3d打印Discone天线的设计与特性研究

采用三维打印技术研究了聚乳酸(PLA)材料宽带分离天线的设计和实验表征。所提出的天线旨在具有700 MHz-6 GHz的宽带工作频率，适合电磁干扰(EMI)传感器应用。在这里，使用3D打印技术是为了实现天线的锥形，而圆盘是使用铜片实现的。为了证明所提出的天线的可行性，还实现了一种由全铜片制成的传统分离天线，并进行了实验表征。从表征结果来看，本文提出的3d打印立体天线在698 MHz频率范围内-10 dB的工作带宽范围大于5.3 GHz。实测的工作带宽表现出明显的宽带特性，比传统的discone天线宽。
