Smart antenna using MTM-MEMS

Abstract

This article presents the design of a novel and compact coplanar antenna using Metamaterials (MTM) and Micro Electro Mechanical Systems (MEMS). The antenna is based on coplanar waveguide (CPW) technology; therefore, the signal and ground are on the same plane, presenting lower dielectric losses and high signal integrity. The designed antenna can be tuned in the frequency range from 5.3 to 5.8 GHz by MEMS capacitors, and it is useful for wireless communications applications, especially beam steering systems. Finally, the design, 3D full-wave simulations and MEMS simulations are presented.
