Novel ultra low voltage mobile compatible RF MEMS switch for reconfigurable microstrip antenna

This paper presents a novel (3.3 v) mobile compatible RF MEMS switch operating in the RF range (DC-6 GHz) in order to be integrated with a reconfigurable microstrip antenna. The switch is a metal series type and utilises dual supply lines controlling 4 electrostatic actuation electrodes with two cantilevers acting vice versa, the design eliminates the stiction problems, suffers low stress levels and has a very high reliability; using gold platinum contacts thus increasing switch life cycles.
