It can be implemented at a less complexity and low cost. Microfluidic technology has been developed to carry out analysis, screening, and detection of very small quantities of biomaterial and chemical samples. While circuits with many switching elements can have many tuning points, tuning is obtained at the expense of higher cost and insertion loss. Impedance tuning has been widely studied using active and passive components, such as microelectromechanical systems (MEMS) components or diode varactors. Conventional impedance tuners comprise mainly three different techniques, namely the single-stub, double-stub, and optimization methods. Impedance tuners are widely used to match impedances, such as antennas, power amplifier (PA) load-pull, and noise characterization, and so on. To solve this problem, the use of an impedance tuner is one of the representative methods of matching the antenna impedance. With the advances in the field of wireless communication systems, an increasing number of components are being incorporated in mobile handset design, reducing the space in which complex advanced antennas can be implemented into the handset.
In particular, as parts of the human body get closer to the antenna, its performance suffers. Antennas significantly influence the performance of the entire application, as their impedance values vary significantly even in operating environments having small changes.
