DESIGNING AND SIMULATING WAVEGUIDE COMBINER 16:1 FOR HIGH POWER APPLICATIONS IN FREQUENCY RANGE OF 8-12 GHZ WITH WAVE TRANSDUCER

摘要

In this paper, a new design of the combiner and mode transducer in X-band is proposed. A two-step structure is applied within the combiner structure to improve isolation between ports. High isolation and wide bandwidth are the major features of the proposed combiner. The results of this paper, simulated by CST, clearly show that the return loss is within an acceptable range. The model converter structure in this paper, as compared to similar structures, is configured in a way that it has less resonance. In this regard, the resonation of the proposed design has successfully been reduced up to one third of similar structures.
