A novel nickel/gold based electroplated 4-bit RF MEMS phase shifter is designed, fabricated and tested. The proposed design can candle high power and utilizes CPW transmission lines that use 8 latching SPDT RF MEMS switches that can work at 80°K. The design is based on 4 cascaded phase shifting units where every unit has two different electrical lengths of CPW transmission lines. Every unit has one...

A novel mm-wave MEMS phase shifter based on a slow wave structure is introduced. The phase shifter uses co-planer wave guide that has the signal line loaded with inductors through capacitive coupling. The inductor and the capacitive coupling capacitor are designed to work for the mm-wave frequency range. Integrated metal to metal RF MEMS switches are designed such that inductors can be shortened to...

This paper describes the design methodology and low-cost solutions implemented in the a low-cost 1K element phased array system. The system operates at 12.2 to 12.7 GHz supporting both left hand and right hand circular polarizations. The total radiation gain is 31.8 dBi and the axial ratio is 1.5 dB. The total height and weight of the system are only 5 cm and 9 Kg respectively. The techniques and...
In this paper a 3-bit reflective-type phase shifter with shunt switches using MEMS technology is implemented. The phase shifter employs a 90 hybrid broadside coupler with two reflective loads. Those loads have variable short ended lengths of transmission lines. The short end in those loads are implemented by the metal to metal contact shunt switches over a segment of CPW line. The average insertion...
