アンテナ装置およびアンテナ装置の製造方法
Document Type and Number:
Japanese Patent JP6981498
Kind Code:
B2
Abstract:
To provide an antenna device capable of easily adjusting an inductance value while having a simple structure, and a manufacturing method of the antenna device.SOLUTION: An antenna device comprises: a core 20A formed by a magnetic material; a bobbin body 30A which is arranged on an outer peripheral side of the core 20A and in which a separation part exists in a middle of a longer direction; and a coil 50A formed by winding a conducting wire 51A to the bobbin body 30A. The coil 50A provides: a density winding part 53A part constructed by winding the conducting wire 51A from one side of the bobbin body 30A to a separation part 33A at high density; and a coarse winding part 54A formed by winding the conducting wire 51A from the separation part 33A to the other side of the bobbin body 30A at low density. A winding direction of a first layer and a second layer constructing the coarse winding part 54A is different, and the conducting wire 51A constructing the first layer and the conducting wire 51A constructing the second layer are overlapped so as to be crossed.SELECTED DRAWING: Figure 1
