A New Design Method for Ultrawideband Microstrip-to-Suspended Stripline Transitions

الملخص EN

A clear and efficient design method for ultra-wideband microstrip-to-suspended stripline transition, which is based on the analytical expressions of the whole transitional structure, is presented.

The conformal mapping is applied to obtain the characteristic impedance of the transitional structure within 2.85% accuracy as compared with the EM-simulation results.

The transition is designed to provide broadband impedance matching and smooth field conversion.

The implemented transition performs less than 0.6 dB insertion loss per transition for frequencies up to 30 GHz.
