Design of Dual Band Ortho-Mode Transducer in Ka-band
The OMT is designed to operate at two frequency bands,with each band passing an orthogonal polarization.For one polarization the band is 16.4-22 GHz and the other 24.4-31 GHz.In order to achieve the miniaturization of the structure,the paper adopts the following preferred techniques: loading two structurally symmetric coupling slots at the lateral ports to facilitate the elimination of high-order mode transmission; in addition,designing one of the coupling slots as a short-circuit structure for more effective reduction of the overall size and more conducive to processing.The high-frequency simulation software CST-2015 was used to optimize the design,and the best results were obtained: the overall length is only 24mm,the return loss is better than-20db in the working frequency band and the port isolation is better than-75dB.
