Abstract :
A new design method based on coupled-mode theory for the TM01 radiator with large aperture is proposed in this paper. The input and output diameter is 70mm and 400mm respectively, and the work frequency is 8.5GHz. The structure designed by the conventional method is 1300mm, and the bandwidth in which the preserve efficiency keeps beyond 90% ranges from 3.3GHz to 9GHz, and preserve efficiency is 97% at work frequency. To shorten the structure, a novel method is proposed. The length of the structure can be reduced to 800mm, with the sacrifices of bandwidth reduction (7.9GHz~9.2GHz) and preserve efficiency reduction (90%) at work frequency. TM01 radiator can be used in the test of high power microwave (HPM) source.
