Coplanar MEMS Phased Array Antenna Using Koch Fractal Geometry

Jahanbakht, M.;Lotfi-Neyestanak, A.A.

Abstract

A 3-bit phase array system including phase shifter blocks and antenna elements has been developed on a coplanar waveguide (CPW) using micro electromechanical system (MEMS) technology. The non Euclidean Koch fractal geometry has been used to improve the frequency behavior of the entire system. It is shown that the fractal geometry makes the design to have lower profile, wider frequency bandwidth, and lower mutual coupling effects. It also decreases the actuation voltage of the MEMS switch elements. The fabrication process has been fully described and the measured values regarding every single block is presented.
