Design of diplexers for E-Band Communication systems

E-Band diplexers have been designed to be used as front-end components in the transceivers of point-to-point wireless communication systems. They are specified to work at the frequency bands 71-76 GHz and 81-86 GHz. Three designs are presented here, two of which are the conventional T-junction and manifold diplexers, and the third is a novel compact structure based on coupled resonators.
