Abstract

본 발명은 셀룰라폰 안테나의 임피던스 조절장치에 관한 것으로서, 이는 안테나 종류 및 셀룰라폰 주변환경에 관계없이 안테나와 송수신단측의 임피던스를 최적으로 조절하여 기지국과 단말기간의 통화율을 최적화 하도록 하는 것이다. 이와같은 본 발명은 안테나측의 임미던스와 통신 단말기의 내부 송수신단측과의 임퍼던스를 매칭시켜 주는 적어도 두개 이상의 임퍼던스 매칭수단과, 상기 송수신단측을부터 반사되는 전파의 양을 측정하는 전력측정수단과, 상기 전력측정수단에서 측정된 전파량과 설정된 기준와를 비교하여 그 결과값을 출력하는 전력비교수단과, 상기 전력비교수단의 결과치에 따라 적합한 상기 임피던스매칭수단을 선택하여 송신단의 전파를 임피던스매칭수단을 통해 기지국으로 송출하고 기지국의 전파를 수신수단으로 전송하는 적어도 두개이상의 매칭선택수단과, 상기 송신단의 전파 또는 임피던스 매칭되어 수신단으로 제공되는 전파를 상기 전력측정수단 또는 매칭선택수단으로 선택적으로 전송하는 서큘레이터로 이루어짐으로 달성되는 것이다.The present invention relates to an impedance control apparatus of a cellular phone antenna, which is to optimize the call rate between the base station and the terminal by optimally adjusting the impedance of the antenna and the transceiver side regardless of the antenna type and the cell phone surrounding environment. As described above, the present invention provides at least two or more impedance matching means for matching an impedance between an antenna side and an internal transceiver end of a communication terminal, and a power measuring means for measuring an amount of radio waves reflected from the transceiver end side. And an electric power comparison means for comparing the amount of electric wave measured by the electric power measuring means with a set reference and outputting the result value, and selecting the appropriate impedance matching means according to the result of the electric power comparing means to match the electric wave of the transmitting end with impedance matching. At least two matching selecting means for transmitting to the base station through the means and transmitting the radio wave of the base station to the receiving means, and selectively transmitting the electric wave of the transmitting end or the electric wave provided by the impedance matching to the receiving end to the power measuring means or the matching selecting means. It is achieved by the circulator.
