Design of Terahertz Passive Tag for High-Resolution Localisation and Scattering

Wireless tracking and sensing technologies have become a vital part of our daily lives. To ensure accurate results, we need to transition towards terahertz (THz) frequencies, which are the future of wireless networks like 5G and beyond. In this frequency range, the wireless channel is highly sensitive to small changes. Our project aims to develop THz passive backscattering tags that will function with a monostatic THz reader, specifically, a leaky wave THz antenna. These tags must have a unique identity so that the reader can accurately identify and distinguish each tag and its position. Backscattering technology uses low-power and passive devices like envelope detectors, dividers, comparators, and impedance controllers, instead of more expensive and bulkier conventional components like local oscillators, mixers, and converters.

This project is linked with a project called "Terahertz Backscattering Device for High-Resolution and Single-shot Localization," funded by the Australian Government through the Office of National Intelligence. The project is open only to Australian or New Zealand permanent residents or citizens due to funding requirements. This is an excellent chance to contribute to the development of novel Australian Defence and intelligence technologies and work on an exciting project.
