This article reviews the application and technology advancement of gallium (Ga)-based
liquid metal (LM) in high-frequency circuits and antennas. It discusses the material …

All antennas in which frequency and radiation patterns can be modified in a reversible and
controlled manner are known as reconfigurable antennas. They are different from other …

Soft conductors are created by embedding liquid metal nanoparticles between two
elastomeric sheets. Initially, the particles form an electrically insulating composite. Soft circuit …

Gallium-based liquid metals are applied in the fabrication of soft electronics because of their
conductivity and flexibility. However, the large surface tension and weak adhesion of liquid …

We report magnetic-field-driven on-demand manipulation of liquid metal in microfluidic
channels filled with base or acid. The liquid metal was coated with iron (Fe) particles and …

Continuous electrowetting (CEW) is demonstrated to be an effective actuation mechanism
for reconfigurable radio frequency (RF) devices that use non-toxic liquid-metal tuning …

The paper presents a multiband frequency reconfigurable microstrip patch antenna structure
loaded by copper-based and water liquid-based superstrate resonators. The frequency …

Gallium‐based room temperature liquid metal alloys have recently been explored to be an
emerging functional material. They have attracted particular attentions in a variety of …

Thanks to the efforts of various research groups over the past decade in the area of tunable
microwave passive components, the idea of tunability has become very well established …

An electrically actuated reconfigurable liquid-metal dipole antenna is presented. Using
electrocapillary actuation, a 5 VDC signal can actuate the liquid metal Galinstan into five …
