Reconfigurability in Radiofrequency/Microwave domain is a trend and an active development field in the scientific research framework due to the evolution of the telecommunication and wireless system as well as connected devices in our daily life. These devices require more and more components operating at high frequencies with wide bands. Those requirements let us in need for an automated and reconfigurable technology that allows parameters adjustment in order to fit the needed specifications.
In this context, as the impedance matching networks are important for Radiofrequency/Microwave circuits design, we have developed our idea with the aim of designing a reconfigurable liquid metal tuner, which allows the matching up to 10 GHz in frequency. The development of this tuner is based on a cavity cell’s design.
The resulting cell is implemented on a grounded coplanar waveguide transmission line. For the tuner reconfigurability, the cell admits 2 distinct states: empty cavity (air) and liquid metalfilled cavity. Therefore, the tuner is made up of 8 cascaded cells resulting the generation of 28 possible cases.
The development of the liquid metal called Galinstan, which exhibits non-toxic Characteristics comparing to Mercury characteristics used previously, has allowed us exploiting it within the framework of our project and discovering the advantages and drawbacks that it shows. In addition, we have studied the way to handle and package it.
