Sub-THz Luneburg Lens Enabled Wide-Angle Frequency-Coded Identification Tag for Passive Indoor Self-Localization

Popis výsledku v původním jazyce

An earlier version of this paper was presented at the 2021 15th European Conference on Antennas and Propagation (EuCAP) and was published in its Proceedings [1]. This paper describes a design, fabrication, and characterization of a planar frequency-coded retroreflector for indoor localization. The retroreflector is fabricated in high-resistive silicon (HR-Si) and consists of a Luneburg lens antenna and a photonic crystal (PhC) high-Q resonator reflective layer, providing ranging and identification within the same tag and bandwidth. The Luneburg lens antenna presents a measured gain of 21.63 dBi at a design frequency 240 GHz. The frequency-coded retroreflector allows for ranging in a continuous 130 degree angular range in azimuthal plane, with a discrete but repeatable 2-resonance identification over multiples of 15 degree. Its maximum measured radar-cross section (RCS) is -23.48 dBsqm at a frequency of 240 GHz. The retroreflective tag set in ideal line-of-sight (LoS) situation is compared to a non-line-of-sight (NLoS) arrangement showing the influence of a metallic rod as an obstacle on the overall tag detection parameters. Finally, the successful read-out of the retroreflective tag is discussed in unknown environments, where no a-priori information is available.
