Abstract :
A MEMS (Micro-Electro-Mechanical Systems) RF (Radio Frequency) switch with the low loss and high isolation is presented. The model of a reconfigurable patch antenna with K and Ku wave bands is set up. 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.
