This paper presents the design and manufacturing of a metamaterial Composite Right/Left Handed (CRLH) directional coupler on silicon substrate in coplanar waveguide (CPW) configuration, with a frequency band between 26-28 GHz. The design makes use of 4 CRLH cells, cascaded and coupled two by two in order to obtain the directional coupler structure. The device was processed on a 500μm thick silicon...
A CPW (coplanar waveguide) coupled-line directional coupler based on CRLH (composite right/left-handed) cascaded structures is designed, analyzed and then fabricated. The technological realization of the coupler involves one mask process on silicon substrate. The measured frequency bandwidth is from 10.5 GHz up to 13.5 GHz fitting well the simulation results.
This paper presents the results in modeling, technological realization and measurements of a CPW (CoPlanar Waveguide) microwave zeroth-order resonating antenna based on CRLH (composite right/left-handed) transmission lines. The CRLH consists of series connected CPW interdigital capacitors and parallel connected CPW transmission lines. The studied device was fabricated on silicon substrate for a subsequent...
The aim of this paper is to present results obtained in modeling, technological realization and measurements for a CPW (CoPlanar Waveguide) zeroth-order resonating antenna, based on CRLH (composite right/left-handed) transmission line. The CRLH consists of series connected CPW interdigital capacitors and two parallel connected CPW transmission lines. The antenna was fabricated on silicon substrate...
The paper presents a design procedure for a distributed switch consisting of an array of MEMSs (micro-electro-mechanical-systems) loading a CPW (coplanar waveguide). The MEMS equivalent circuit is developed from the scattering parameters obtained by using a full-3D electromagnetic simulator and then this equivalent circuit is used to design the switch. The designed switch consisting of 3 MEMSs are...
