Abstract :
Characteristics of modes on the conductorbacked slotline, the inverted conductor-backed slotline and on its modification in which the top dielectric layer with higher permittivity has a finite thickness are presented in this paper. Only the modified inverted conductor-backed slotline is able to transmit the dominant bound mode. The inverted and modified inverted conductor-backed slotlines are real candidates for the design of leaky wave antennas.
