FERRITE COMPOSITION, FERRITE PLATE, MEMBER FOR ANTENNA ELEMENT AND ANTENNA ELEMENT
PROBLEM TO BE SOLVED: To provide a ferrite plate suitable for wireless communication without contact and for an antenna element having long communication distance form low temperature area (for example 0°C) to high temperature area (for example 40°C), a member for antenna element consisting of the ferrite plate and an antenna element having any of them.SOLUTION: A ferrite plate contains iron oxide of 46.3 to 49.5 mol% in terms of FeO, copper oxide of 4.0 to 15.6 mol% in terms of CuO, zinc oxide of 20.4 to 25.0 mol% in terms of ZnO and the balance nickel oxide as main components and titanium oxide of 1.4 to 2.0 mass% in terms of TiOand cobalt oxide of 0.5 to 2.0 mass% in terms of CoO as accessory components excluding inevitable impurities and further at least one of silicon oxide of 0.005 to 0.030 mass% in terms of SiOand calcium oxide of 0.020 to 0.100 mass% in terms of CaO as an accessory component to the main components.SELECTED DRAWING: Figure 1
【課題】非接触での近距離無線通信に適し、低温領域（例えば０℃）から高温領域（例えば４０℃）において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及びこれらのいずれかを備えたアンテナ素子の提供。【解決手段】主成分が酸化鉄をＦｅ２Ｏ３換算で４６．３〜４９．５モル％、酸化銅をＣｕＯ換算で４．０〜１５．６モル％、酸化亜鉛をＺｎＯ換算で２０．４〜２５．０モル％を含有し、残部が酸化ニッケルで構成されており、前記主成分に対して、不可避不純物を除き、副成分として、酸化チタンをＴｉＯ２換算で１．４〜２．０質量％、酸化コバルトをＣｏＯ換算で０．５〜２．０質量％含有し、さらに前記主成分に対して副成分として酸化ケイ素をＳｉＯ２換算で０．００５〜０．０３０質量％、酸化カルシウムをＣａＯ換算で０．０２０〜０．１００質量％の少なくとも一方を含有する。【選択図】図１
