论文摘要
在室内室中设计，创建和测试了具有高定向性的双色型天线。本文介绍了1至5 GHz之间的结果。特别是，已经测试过两种不同的配置，具有和没有介电镜头，均涉及介电和天线支撑的快速原型制作工具（3D打印）。如今，有效且可持续的点对点通信或能量转移协议需要很高的方向性，以避免在邻近地区释放能源并保留数据传输安全性。如这里所示，具有3D印刷聚乳酸（PLA）介电晶状体的特殊双色天线可以达到良好的方向性，相应的发射叶以约8.4度左右，其FWHM为6.4度。具有非常规形状的无介质无镜头天线也可以实现良好的方向性，相应的发射叶子集中在10.0度左右，其FWHM为14.2度。此处显示的初步结果探讨了庞大的配置空间的某些方面（包括制造技术，介电材料，导电支撑等），并打开途径以进行进一步优化研究。目的是调整各种自由度，以实现可以定义为“无限”方向性的东西。
Biconical-type antennas featuring high directivity have been designed, created, and tested in anechoic chamber. Results in the range between 1 and 5 GHz are presented in this article. In particular, two different configurations have been tested, with and without dielectric lenses, both involving rapid prototyping tools (3D printing) for the dielectric and the antenna support. A very high directivity is nowadays demanded by efficient and sustainable point-to-point communications or energy transfer protocols, to avoid releasing energy in neighboring areas and preserve data transfer security. As demonstrated here, special biconical type antennas featuring a 3D printed polylactic acid (PLA) dielectric lens can achieve a good directivity, with a corresponding emission lobe centered around 8.4 degrees, featuring a FWHM of 6.4 degrees. Dielectric lens-free antennas, featuring an unconventional shape, can also achieve a good directivity, with a corresponding emission lobe centered around 10.0 degrees, featuring a FWHM of 14.2 degrees. The preliminary results shown here explore some of the aspects of the vast configuration space (which include fabrication techniques, dielectric materials, conductive supports, etc.) and open the route for further optimization studies. The aim would be to adjust the various degrees of freedom in order to achieve what can be defined as "infinite" directivity.
