There are provided a mobile satellite communication terminal and a method of using the same in which the dual-mode communication can be conducted by one terminal, and the antennas of both modes are housed and arranged on one axis in a configuration simpler than that of the prior art to thereby reduce the volume also when the user carries about the terminal. The satellite antenna 6 is configured in a shape of a hollow cylinder and the ground antenna 5 is arranged in a hollow section thereof, the satellite antenna 6 is configured to be housed into/to be drawn from a terminal housing, and there are also configured a 4-wire helical antenna element section 61 in which a conductor wire 611 is helically wound on a cylinder surface and an antenna feeder section 62 which is integrally disposed in a lower section of the 4-wire helical antenna element section 61 and in which circuits 621, 622, and 623 are formed on a cylinder surface. <IMAGE> |
