Abstract
Description
Claims (3)
- 정전압소자에서 출력되는 전압을 분배하여 상기 안테나에 일정 전류를 공급하기 위한 전압분배부와;상기 전압분배부를 통해 상기 안테나에 일정 전류가 공급되고 있는 상태에서 그 안테나에 나타나는 전압강하를 검출하기 위한 전압검출부와;상기 전압검출부를 통해 검출되는 전압강하를 근거로, 상기 안테나가 피씨비에 정상적으로 부착되었는지의 여부를 판단하는 중앙처리장치로 구성한 것을 특징으로 하는 이동통신 단말기의 안테나 부착 확인회로.
- 제1항에 있어서, 전압검출부는 연상증폭기를 포함하여 구성된 것을 특징으로 하는 이동통신 단말기의 안테나 부착 확인회로.
- 제1항에 있어서, 중앙처리장치는 상기 전압검출부를 통해 검출되는 전압이 원래 전압보다 일정치 이상 강하된 경우, 상기 안테나가 피씨비에 정상적으로 부착된 것으로 판단하여 그 사실을 표시장치에 표시하도록 구성된 것을 특징으로 하는 이동통신 단말기의 안테나 부착 확인회로.
