Scale changing technique design and optimisation tool for active reflect-arrays cell

This study deals with the design and optimisation of an active phase-shifter cell for MEMS-based reflect-arrays. Technological implementation was investigated in order to enhance the cell performances. The sensitivity of these performances to MEMS capacitance ratio as well as MEMS failure were studied. Those studies were performed using the scale changing technique (SCT). Lastly, extra performance improvement was investigated using genetic algorithm and DOE- based optimisation techniques.
