摘要

It is well known that high transmission loss occurs when millimeter wavestraveling through the atmosphere. As an alternative, power line is proposed asa transmission media to combat the high loss. In this article, a threedimensional(3D) printed high-gain circularly polarized antenna was proposedfor millimeter-wave broadband power line communications. It has a simplestructure, where tapered slots are designed between the upper and lower layersof the waveguide to generate the circularly polarized operation. A wide impedancebandwidth of 31.58% (24-33 GHz) and an axial ratio bandwidth of 28.07%(24.5-32.5 GHz) are achieved by the proposed design. A maximum gain of11.2 dBi is measured from the 3D printed structure. The proposed antenna hasa simple structure which is easy to adjust to any working frequency. Theantenna can be excited by properly integrated to the waveguide that connectedto the power line end. The use of 3D printing technology enables a low-costsolution millimeter-wave broadband communications over the power line.
