Abstract
A V-band rod antenna with constant gain based on spoof surface plasmon polaritons (SPPs) is proposed in this paper. In this design, a periodic metallic grating operates as a SPP transmission line, which can provide high EM field confinement and achieve a low insertion loss (only 0.079dB/mm at 60GHz). Meanwhile, due to the SPPs unique dispersion characteristic, a broadband rod antenna is designed with high gain. This rod antenna is conveniently fabricated by 3D printing followed by metalization. The simulated results show that the proposed rod antenna can cover V-band from 50 to 75GHz with| S11| < −15dB and achieve a gain of 15.8 dBi with less than 1.2dBi variation. The measured −10dB bandwidth is from 50GHz to 70GHz with 12.87dBi-16.5dBi gain.
