Micromachining has been applied to microwave and millimetre wave field to create low loss and high performance passive/active components and antennas. In this talk, starting from Modelling of transmission lines and discontinuities, design procedure to realize passive components in micromachined media will be presented. Next, design, modelling and fabrication of different types of micromachined antennas will be described. Methodology for the design, development and fabrication of RF MEMS switches on GaAs, Quartz and Silicon substrates will then be presented. The schemes for developing reconfigurable RF MEMS circuits using either variable capacitors or RF MEMS switches will be discussed. The reconfigurable circuits include: a band pass filter, band stop filter, high isolation switch and a patch antenna.
