CPW Antenna Fabricated on Silicon Substrate, Based on Transmission Line Metamaterial Approach

Abstract

The paper presents results obtained in modeling, technological fabrication and measurements for a CPW (coplanar waveguide) zeroth-order resonating antenna, based on CRLH TL (composite right/left-handed transmission line). The CRLH TL consists of cascaded cells of series CPW interdigital capacitors and parallel CPWs. The antenna was fabricated on silicon substrate. This was designed and analyzed using commercial electromagnetic software (IE3D-Zeland), A very good agreement between the experimental and the simulation results has been observed for the return-loss as well as for the gain and the radiation pattern.
