Liquid Antennas for Radio Communications

#electromagnetics #propagation #antennas #GPS #Radio_Communication #liquid_antennas

Antennas are normally made of metal in order to achieve high radiation efficiency.


Unlike metal antennas, liquid antennas are a new type of antenna that has some unique features and gained a lot of attention recently. The University of Liverpool has been working in this area for many years. In this talk, the advantages, disadvantages, and challenges of using such a liquid antenna for real work applications will be discussed at the beginning, and then it will be followed by the latest development on the liquid material and the liquid antenna designs and development. A new concept of using gravity in making liquid antennas for beam-steering and GPS applications will be used as an example in this talk. Other antennas, such as a hybrid antenna of the dielectric resonant antenna (DRA) and magneto-electronic (ME) dipole will also be introduced and discussed. The talk will be finished with the introduction of a new design that is suitable for antenna diversity and MIMO applications.


Some relevant activities at the High-Frequency Engineering Group at the University of Liverpool will also be introduced briefly.

Liquid Antennas for Radio Communications


Prof Yi Huang has been conducting research in the areas of antennas, wireless communications, applied electromagnetics, radar, measurements, and EMC since 1987. More recently, he is working on antenna developments using liquid and new materials, wireless energy harvesting and power transfer. His experience includes 3 years spent with NRIET (China) as a Radar Engineer and various periods with the Universities of Birmingham, Oxford, and Essex in the UK as a member of research staff. He worked as a Research Fellow at British Telecom Labs in 1994 and then joined the Department of Electrical Engineering & Electronics, the University of Liverpool, UK as a Faculty in 1995, where he is now a full Professor in Wireless Engineering and the Head of High-Frequency Engineering Group.

Prof Huang has published over 500 refereed papers in leading international journals and conference proceedings and authored four books, including Antennas: from Theory to Practice (John Wiley, 2008, and 2021). He has received many patents, and research grants from research councils, government agencies, charities, EU, and industry, and is a recipient of over 10 awards (e.g. BAE Systems Chairman’s Award 2017, and IET Premium Award for Best Paper 2022). He has served on a number of national and international technical committees and has been an Editor, Associate Editor, or Guest Editor of five international journals (including IEEE AWPL 2016-2022). In addition, he has been a keynote/invited speaker and organiser of many conferences and workshops (e.g. IEEE iWAT2010, LAPC2012, and EuCAP2018). He is at present an Associate Editor of IEEE Trans on Antennas and Propagation, UK and Ireland Rep to the European Association of Antenna and Propagation (EurAAP), a member of the IEEE AP-S New Technology Directions Committee, and a Distinguished Lecturer of IEEE-APS (2023-2025), and a Fellow of IEEE.
