Postdoctoral researcher – Wireless Communications

<strong>Postdoctoral researcher – Wireless Communications <br/>Contract Type: Full Time/Fixed Term (1.5 years approx.)</strong><br/><br/>Frozen food is a staple in the daily diet of millions worldwide, particularly in developing countries. It provides extended shelf life, reduces food waste, and directly supports societal development goals. However, ensuring that frozen goods remain at sub-zero temperatures throughout transport and storage—the so-called “cold chain”—remains a major logistical challenge. Breaks in the cold chain not only compromise food safety and quality but also lead to significant economic losses. Efficient, reliable, and accountable cold-chain monitoring is therefore essential.<br/><br/>A critical barrier to widespread adoption of monitoring solutions is cost. The frozen food industry operates with traditionally low profit margins, meaning that any added monitoring system must be inexpensive, disposable, and easily integrated. Radio Frequency Identification (RFID) technology has emerged as a promising solution. Over the past decade, RFID has gained substantial attention across a range of Internet of Things (IoT) applications, from access control and e-health management to the Meeting, Incentives, Conferences, and Exhibitions (MICE) industry. Its appeal lies in its low cost, compactness, and simplicity of deployment. Passive RFID tags, in particular, are attractive because they are battery-free and powered solely by the energy transmitted from the RFID reader.<br/><br/>Building on this foundation, this project—funded by ARC-HUB—seeks to develop next-generation antenna for RFID tags with integrated sensing capabilities. In the context of frozen food supply chains, these novel antennas will not only transmit a package’s unique identification number but also indicate whether the product has been exposed to temperatures above zero, by altering the input impedance of the tag. This sensing mechanism is designed to be seamless: when illuminated by a standard UHF RFID reader, the tag will transmit a different identification code depending on the sensed temperature state. In this way, the proposed technology transforms passive RFID from a simple tracking tool into a low-cost, disposable sensing platform for cold-chain accountability.<br/><br/>The successful candidate joining this project will become part of the newly established and dynamic <strong>Wireless Communications Laboratory. </strong>They will engage in cutting-edge antenna research at the intersection of wireless communications and advanced materials, with the opportunity to collaborate with world-leading experts in both fields. The candidate will also gain access to state-of-the-art facilities, including material processing laboratories, mm-wave to sub-THz characterization systems, antenna measurement chambers, and advanced manufacturing infrastructure.
