A MEMS (Micro-Electro-Mechanical Systems) RF (Radio Frequency) switch with the low loss and high isolation is presented. A model of a reconfigurable patch multi-band antenna is set up and simulated by HFSS software. The reconfigurable antenna has two work frequencies by changing the topology structure with the RF switch. The bandwidth is expanded from 1.16% to 7.71% by adding two parasitic patches. The resonance frequencies are 20.1GHz and 12.5GHz, respectively. The gains of K and Ku wave bands are obtained.
