“…Changing the voltage polarity will withdraw the liquid metal back into the reservoir, which also changes the shape and position of the antenna. On the other hand, ECC has been used in the cylindrical helical antenna to alter the length of liquid metal in the microfluidic channel in [ 44 ]. The EGaIn oxide layer which has been produced electrochemically increases the interfacial tension of liquid metal, thus driving the liquid metal to the channel.…”

Advances in reconfigurable liquid-based reconfigurable antennas are enabling new possibilities to fulfil the requirements of more advanced wireless communication systems. In this review, a comparative analysis of various state-of-the-art concepts and techniques for designing reconfigurable antennas using liquid is presented. First, the electrical properties of different liquids at room temperature commonly used in reconfigurable antennas are identified. This is followed by a discussion of various liquid actuation techniques in enabling high frequency reconfigurability. Next, the liquid-based reconfigurable antennas in literature used to achieve the different types of reconfiguration will be critically reviewed. These include frequency-, polarization-, radiation pattern-, and compound reconfigurability. The current concepts of liquid-based reconfigurable antennas can be classified broadly into three basic approaches: altering the physical (and electrical) dimensions of antennas using liquid; applying liquid-based sections as reactive loads; implementation of liquids as dielectric resonators. Each concept and their design approaches will be examined, outlining their benefits, limitations, and possible future improvements.

“…The interest in reconfigurable antennas in the past few years has grown due to their capability of enabling tunability and switchability in antenna designs. While the implementation of RF switches such as PIN diodes [1, 3,18,48,49] have increased the growth of such versatile antennas, the number and range of switching states increases with the increase of circuit complexity [21]. This motivated the choice of metal fluids, which changes the antenna characteristics using fluid flow as an alternative for antenna reconfiguration.…”
