Abstract

A novel TE₀₁-TE₂₀ mode converter is designed and fabricated by 3-D printing in this paper. It can realize high-efficiency (>97.5%) mode conversion in broadband from 27 to 40 GHz. Its weight is 0.011 kg only, and its coupling cavity normalized length is 0.39λ. An out-of-phase power divider is designed to verify the mode converter by observing the difference of output phase and flat frequency characteristics when connected to the mode converter. A sample converter with a power divider was then tested. Flat frequency characteristics for power dividing and anti-phase outputs are obtained in the working bandwidth to verify the mode converter with a good performance of mode conversion.
