Design of a 94 GHz transition section with cosinusoidal profile

But a transition section with cosinusoidal profile, its operation principle and how to design it have not been found in available literature until now.

Summary: | Up to now, many transition sections have been designed and applied successfully. But a transition section with cosinusoidal profile, its operation principle and how to design it have not been found in available literature until now. In this study, a transition section with a cosinusoidal profile and the method to design it are proposed based on the operational principles of mode converters with similar profiles. A 94 GHz transition section used to transmit TE
01
mode efficiently is designed using the method. The calculations by our codes and simulations on a high-frequency structure simulator indicate that the section can transmit TE
01
mode with transmission efficiency over 0.987 (within a bandwidth of 7.6 GHz) and reflection below −40 dB. Experimental results show our design is successful. Comparison between the section and the linear one shows that the former is much shorter than the latter when they are used to transmit TE
01
mode at the same characteristics above. Such a strong point of shorter length is very helpful for the construction of a compact microwave device. |
