The upcoming transition towards 5G technology leads to tremendous growth in the field of Wireless communications and there is need for novel technology which is cost affordable and has higher throughput, better coverage and capacity. The 5G technology needs smart phones to fit more antennas into less space. This increases complexity in the RF Handsets as there is need for redundant Impedance Matching Networks (IMN) corresponding to each antenna to ensure maximum power transfer by reducing mismatch losses. In order to resolve the encountered problem, Microelectromechanical switches (MEMS) incorporated IMN has to be designed as they have better performance, power handling capability, less power consumption and low losses at high frequencies. MEMS based Radio Frequency (RF) switches offers reconfigurable nature to the networks which in turn avoids presence of hardware redundancy consuming much space in chip area. In this paper work, a RF MEMS switch based Reconfigurable IMN is designed for 5G applications operating at sub-6GHz. The matching network is designed using Lumped Element Network method. Electromagnetic modelling of MEMS Switches are done using COMSOL Multiphysics and Simulation results of S-Parameters for the designed reconfigurable IMN are obtained using Advanced Design System that showed maximum response at desired frequencies.
