| Abstract: | A new type of high-power microwave mode-transducing antenna is presented, which integrates the fin-inserted mode converter and a novel horn in one structure. It can directly radiate the coaxial TEM mode or circular TM_ 01 mode from high-power microwave sources, and has the virtues of compactness, high aperture efficiency, boresight peak, easy fabrication, and so on. An antenna for 3.8 GHz is designed with the length of about 300mm and the aperture diameter of 280mm. The calculated results show that it produces a gain of 19dBi at 3.8 GHz, and in the range of 3.7~4.1GHz, the gain exceeds 18.7dBi, the return loss is below -15dB. |
