MEMS Switch for 60 GHz Band

The aim of this work was to develop a new MEMS switch structure for millimeter wave applications, which can be integrated with other more complex devices for developing of reconfigurable filters or antennae for microwave or millimeter wave frequency range. Electrostatic force was chosen for the switching operation, which seams to be the only way to obtain high reliable and wafer scale manufacturing techniques at these frequencies. Different geometries of the switching element were designed and manufactured in order to study the mechanical stability of these structures; the measured actuation voltage, of about 24,5V, shows an acceptable value for the further applications. Measured and simulated results of these structures (insertion losses of about 0.75dB@60GHz and isolation >50dB@60GHz) were in good agreement and are promising for further applications in this frequency range
