Abstract

Abstract

A model of a compact wide-band TM01-TE11 mode converter with power capacity more than 1 GW and the maximum dimension of φ20.5 cm×55.2 cm is designed, in which the coaxial TEM and rectangular TE10 modes are used as the intermediate modes. When the frequency is 1.63~2.22 GHz, the conversion efficiency of the converter is over 90% with bandwidth over 30%, and the reflectance is less than -11 dB. The highest conversion efficiency is 99.8% and lowest reflectance is -26.3 dB when the frequency is 1.72 GHz. The input and output ports of the converter are exactly aligned on the same axis, which is helpful for designing the compact microwave launching systems.
