Abstract

A bandpass tunable RF filter is proposed by using Radio Frequency (RF) Microelectro Mechanical Systems (MEMS). The tenability is obtained by using capacitive MEMS switches. The performance of the filter depends on geometry and location and types of the MEMS switches. The paper described the optimization procedure to design a bandpass filter that can be tuned within the bandwidth of 3.6 GHz to 4.4 GHz by using high frequency electromagnetic simulator (HFSS).
