DIELECTRIC-LOADED SHIELDED EDGE-COUPLED CONDUCTOR-BACKED COPLANAR WAVE-GUIDE STRUCTURES

In this paper, a study of dielectric loading for shielded edge-coupled conductor-backed coplanar waveguide (CBCPW) is carried out with respe ct to mode coupling, isolation, and coupling factor. It is shown that with appropriate dielectric loading, mode coupling can be avoided whil e maintaining good isolation and impedance characteristics. Also, the effect of variation in enclosure, slot, and strip dimensions on the di spersion and impedance characteristics of dielectric-loaded edge-coupl ed CBCPW is presented. The results have been obtained using the semian alytical technique, Method of Lines.
