FERRITE PLATE, MEMBER FOR ANTENNA ELEMENT AND ANTENNA ELEMENT
PROBLEM TO BE SOLVED: To provide a ferrite plate suitable for non-contact near distance of wireless communication and for an antenna element having long communication distance, a member for an antenna element containing the ferrite plate and an antenna element containing any of them.SOLUTION: There is provided a ferrite plate formed from a Ni-Cu-Zn-based ferrite sintered body containing oxide of Co and Ti and tungsten oxide as an accessory component of 0.02 to 0.5 mass% in terms of WObased on 100 mass% of a Ni-Cu-Zn-based ferrite mainly containing Fe, Ni, Cu and Zn.
【課題】非接触での近距離無線通信に適し、通信距離が長いアンテナ素子に好適なフェライトプレート、該フェライトプレートからなるアンテナ素子用部材、およびこれらのいずれかを備えたアンテナ素子を提供すること。【解決手段】Ｃｏ及びＴｉの酸化物を含有し，Ｆｅ，Ｎｉ，Ｃｕ及びＺｎを主成分とするＮｉ−Ｃｕ−Ｚｎ系フェライト１００質量％に対し、副成分として酸化タングステンをＷＯ３換算で０．０２〜０．５質量％を含有するＮｉ−Ｃｕ−Ｚｎ系フェライト焼結体から形成されることを特徴とするフェライトプレート。【選択図】 図１
