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.

What is a Mode?
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...
