Abstract

In this paper, there is presented a metamaterial diplexer designed and implemented in microstrip technology. It uses two types of structures which allow to minimize the dimensions of the overall device and to enhance the working bandwidth. An equivalent model of the structure and analytical expressions are given as a starting point in the optimization process. The measurements confirm the theoretical and simulated results. The transfer characteristic for the first channel is from 2GHz to 4.25GHz, respectively for the second channel is from 4.25GHz to 7GHz..
