Study on dynamic characterization of a shunt capacitive RF MEMS switch

This chapter proposes a novel method to reduce the specific absorption rate (SAR) of a compact CPW antenna. A combination of three efficient techniques is employed to develop a dual-band bowtie metamaterial antenna with safer SARs. Following this approach, the authors have designed a low-profile antenna with a footprint of only 0.074λ02 and low backward radiation. The simulated results confirm the antenna's suitability for wireless body area network devices operating in the Unlicensed National Information Infrastructure (U-NII) at 5.33 GHz and 18.17 GHz frequency bands for military radar applications. The authors have developed two oppositely faced B-shaped resonators to form the bowtie-shaped DNG unit cell. A compact size and dual-band operation were attained by loading the bowtie-shaped into the CPW antenna. The antenna's conception used the available package CST software, printed on Rogers RT5880, and the CPW-fed monopole mechanism for the excitation.
