We report the velocity slowing of a coplanar interdigitated meander tr
ansmission line on a dielectric substrate. Contrary to conventional tr
ansmission lines, the phase velocity has been determined by altering b
oth the capacitance and the inductance. A simple analysis of this devi
ce has been carried out with the use of CAD packages. Theoretical resu
lts showed good agreement with measured results. (C) 1996 John Wiley &
