PURPOSE:To realize an antenna with an excellent characteristic while improving the portableness resulting from miniaturization by providing one out of two antennas and a microphone to a prolonged part main body provided freely telescopically to a radio telephone set and controlling a phase of a transmission reception signal fed to the antenna. CONSTITUTION:The telephone set consists of a radio telephone set main body 11, a prolonged part accommodation recessed part 12, a prolonged part main body 13, a speaker 14, a 1st antenna 15, a 2nd antenna 16 and a microphone 17 or the like. Then one antenna and the speaker 14 or the microphone 17 are provided to the prolonged part main body 13 employing the two antennas 15, 16, controlling the phase of one transmission reception signal and provided freely telescopically on the radio telephone set main body 11. Thus, the antenna with the excellent characteristic is realized while improving the portable performance resulting from the miniaturization. |
