A novel approach of RF MEMS resistive series switch for reconfigurable antenna

This paper gives the optimization approach for radio frequency microelectromechanical (RF MEMS) resistive series switch. The RF MEMS switches are used to reconfigure the RF circuits. There will be need to obtain the best value of switch parameters, which play an important role in electromagnetic circuitry. Further, this paper provides a novel parametric variation method by varying the physical dimensions to optimize the switch performance. The proposed switch exhibit pull-in response of 18 V. The insertion loss performance of switch is in the range of -0.1496 dB to -0.5172 dB at closed position and isolation is in the range of -73.9119 dB to -33.7987 dB at open position. The switch offer outstanding performance from 0.1 to 10 GHz frequency. The final designed resistive switch is then integrating on planar antenna to reconfigurable it at different frequencies, which supports wireless and mobile communication.
