Zusammenfassung: | In this article, the designs of the K/Ka-Band reconfigurable Substrate Integrated Coaxial Line (SICL)-to-waveguide transitions are presented. Two types of reconfigurable SICL-to-waveguide transitions, with stepped impedance transformers waveguide transitions and ridge waveguide transitions, are designed for two operation frequency modes (K/Ka-band). Both simulated and experimental results are presented for the demonstration. Results indicate that the reconfigurable waveguide structure has the advantages of broad bandwidth and low return loss for both K/Ka-band compared with the conventional dual-band waveguide transitions. The presented waveguide transition designs with high function flexibility will be significant to satellite communication applications and massive MIMO beamforming networks with an active phased antenna array. |
