Abstract
It can be expected that a coplanar waveguide (CPW) bend would present different transmission characteristics from those of a microstrip-line (MSL) bend because, unlike MSL, CPW has a signal conductor and two ground conductors on the same side of the substrate. This paper describes the crosstalk characteristics of two adjacent CPW bends separated by a ground conductor and formed on a printed circuit. Grosstalk characteristics of CPW bends of various line-separations at near and far ends were studied and compared with those of two adjacent straight CPW's, and also with those of MSL bends of the corresponding structures. Excepting the case of close coupling, crosstalk characteristics of CPW bends generally show a maximum at some frequency.
