Document Type and Number:
Japanese Patent JP7224716
Kind Code:
B2
Abstract:
There is provided an antenna device 1 in which an antenna housing accommodates an antenna element that receives signals in the FM and AM bands. The antenna element includes a first element that receives signals in the FM band and a second element that surrounds the first element and receives signals in the AM band. Each of the elements includes a capacitance loading plate (a conductive plate) having a predetermined area and the capacitance loading plates are provided in an identical plane or a substantially identical plane. The first element includes a plurality of coils 14a and 14b, each coil having one end coupled to the capacitance loading plate 12 of the first element, and these coils operate, in conjunction with the capacitance loading plate 12, as a series resonance circuit in the FM band.
