An RF MEMs microelectromechanical system variable capacitor has been demonstrated with a 22:1 tuning range, tuning from 1.5 to 33.2 pF of capacitance. This capacitor was constructed using bistable MEMs membrane capacitors with individual tuning ranges of 70:1 to 100:1, control voltages in the 30-55

RF MEMS tuners with wide impedance coverage have been developed for 6-24 GHz noise parameter and load-pull measurement systems. The tuners are based on triple-, double-, and single-stub topologies loaded with switched MEMS capacitors. Several designs are presented, and they use 10-13 switched MEMS c
Two novel badge-sized extremely low-profile TAG antennas have been developed. They have been manufactured by means of different methods of input impedance tuning. They are aimed at the UHF radiofrequency identification of persons in case of moderate distances. The low-permittivity substrate has been

## Abstract An asymmetric RF microelectromechanical systems (MEMS) capacitive switch with a novel architecture employing mode switching from a coplanar waveguide (CPW) mode to a coupled slotline (CSL) mode is reported for selected frequency within the 2β10 GHz low microwave frequency range. An addi
A unified, macroscopic, one-dimensional model is presented for the quantitative description of the process of dielectric charging in radio frequency micro-electromechanical systems (RF MEMS) switches. The fidelity of the model relies on the utilization of experimentally obtained data to assign value
