On the basis of backward coupling and left-handed microstrip line, new designs of duplexers and multiplexers will be presented and tested in di®erent con¯gurations. By using microstrip lines with Complementary Split Ring Resonators (CSRRs) etched on the ground plane along with series capacitive gaps in the upperconductor, forward coupling will be inverted into backward coupling.Compact size and fully planar fabrication techniques are importantcharacteristics in the devices proposed.
