METODA DAN ALAT UNTUK MENGELUARKAN DAN MEMASUKKAN SUATU ANTENA SECARA ATOMATIS DALAM SUATU TELEFON TANPA KABEL

摘要

PURPOSE: An automatic antenna retracting/extending apparatus and method is provided to achieve an improved sensitivity and use convenience, while minimizing battery consumption. CONSTITUTION: An apparatus comprises an antenna drive signal generating unit for generating a drive signal corresponding to a communication start or end command; a motor(4) having a motor shaft, and which rotates the motor shaft in a forward or reverse direction corresponding to the polarity of the power voltage being supplied; a control unit(2) electrically connected to an output terminal of the antenna drive signal generating unit and an input terminal of the motor, and which obtains information regarding antenna retraction or extension by checking the signal output from the antenna drive signal generating unit, and controlling the motor by supplying a motor drive signal for rotating the motor at a predetermined time interval during a set time period required for completely extending or retracting an antenna(8); a gear unit(6) coupled integrally with the motor, and which retracts or extends the antenna by the rotating force transmitted from the motor shaft; and an attachment unit for attaching the motor and gear unit to an antenna housing.
