Slot Lines Slot line consists of a narrow gap (or slot) in a conductive coating on a dielectric substrate, as shown in Fig. 31. The geometry is planar and is well suited for its usage in microwave integrated circuits. , €r = 16) so that the fields are closely confined to the slot and the radiation loss is minimized. T~e nature of the slot-mode configuration is such that the electric field extends across the slot while the magnetic field is in a plane perpendicular to the slot and forms closed loops at half-wave intervals.
