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.
