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...
