Design and implementation of a dual band six-port junction

In this paper we propose two different topologies for dual band six-port junctions. They are designed in Microstrip technology to operate at 1.5 GHz and 2.7 GHz carrier frequencies. The results of the EM simulations revealed a good matching for both topologies. However, the performance analysis in terms of frequency bandwidth, reflection loss and qe points demonstrated the superiority of the non symmetrical topology compared to the symmetrical one.
