Antenna

Abstract

Abstract PURPOSE:To increase the gain and to eliminate the directivity by providing a ferrite antenna formed by winding the 1st winding to a ferrite rod, the 2nd winding wound while the earth end of the 1st winding is used as the turn start and a rod implanted vertically to the ferrite rod at the end turn of the 2nd winding. CONSTITUTION:The ferrite antenna 1 formed by winding the 1st winding 3 to the ferrite rod 2, the 2nd winding 5 wound while the earth side of the 1st winding 2 is used as the start turn and the rod 4 implanted vertically to the ferrite rod 2 at the end turn of the 2nd winding 5 are provided. In the title antenna system, the strong directivity of the ferrite antenna is cancelled by the rod implanted vertically to the ferrite rod, the effect of a human body is made not susceptible and stable reception is attained. Further, the gain is increase than the antenna gain of the ferrite antenna or the rod antenna and the reception sensitivity is improved.
