Abstract

안테나에 있어서 수신용 안테나에 관한 것으로 특히 체널변경시 방송수신이 가장 좋은 상태로 안테나의 방향이 변경되는 AFT안테나방법에 관한 것이다. 채널변경시 마이콤은 튜너에 제어신호를 출력하여 전파의 수신상태가 변경된 채널에 최적의 수신상태로 변환되는 자동미세동조과정과, 자동미세동조과정 후 판단수단을 통하여 자동 미세동조상태가 최적의 상태인가를 판단하는 자동미세동조상태 판단과정과, 자동미세동조가 최적의 상태가 아니면 안테나형태를 변형하는 안테나형태변형과정과, 안테나형태가 변함에 따라서 발생되는 신호에 의해 안테나의 형태가 변환되는 값을 계산하는 계산과정으로 구성된다. 채널변경시 전파수신상태가 나빠도 사용자가 직접 손으로 안테나의 방향을 변경시키지 않고도 최적의 전파수신을 할 수 있는 이점이 있다.The present invention relates to a receiving antenna in an antenna, and more particularly, to an AFT antenna method in which a direction of an antenna is changed in a state where broadcast reception is best when a channel is changed. When the channel is changed, the microcomputer outputs a control signal to the tuner and converts the radio wave reception state into an optimal reception state. The automatic microtuning state determination process for determining the authorization, the antenna type deformation process for modifying the antenna shape if the automatic microtuning condition is not optimal, and the value of the antenna being changed by the signal generated as the antenna shape changes. It consists of a calculation process that calculates. Even if the radio wave reception condition is bad at the time of changing the channel, there is an advantage that the user can optimally receive the radio wave without changing the direction of the antenna by hand.
