| Abstract: | As the element of satellite borne antenna, one new kind of conic horn antenna worked at 20/30 GHz dual band is designed in this paper. By considering a metalcylinder with a shape changed gradually into the conic horn, the input impendence can be changed. By modeling the parameters of metal cylinder such as the diameters of both ports and the length of the metal cylinder, the demand input impedance of the conic horn can be obtained. Both simulation results and measurement results show that the satisfied impedance and pattern characteristics for interested bands are obtained. |
