FERRITE COMPOSITION, FERRITE PLATE, MEMBER FOR ANTENNA ELEMENT AND ANTENNA ELEMENT
PROBLEM TO BE SOLVED: To provide a ferrite composition suitable for an antenna element having long communication distance in high frequency band (e.g. 13.56 MHz), a ferrite plate containing the ferrite composition, a magnetic member for antenna element consisting of the ferrite plate, an antenna element having the ferrite plate or the member for antenna element.SOLUTION: There is provided a ferrite composition having a main component containing iron oxide of 45.0 to 49.5 mol% in terms of Fe2O3, copper oxide of 4 to 16.0 mol% in terms of CuO, zinc oxide of 19.0 to 25.0 mol% in terms of ZnO and the balance nickel oxide, and containing titanium oxide of 0.5 to 2 mass% in terms of TiO2, cobalt oxide of 0.35 to 2 mass% in terms of CoO as accessory components to the main component excluding inevitable impurities.
【課題】高周波帯域（たとえば１３．５６ＭＨｚ）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組成物と、該フェライト組成物からなる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磁性部材と、該フェライトプレート、あるいは該アンテナ素子用部材を有するアンテナ素子とを、提供することを目的とする。【解決手段】主成分が、酸化鉄をＦｅ２Ｏ３換算で４５．０〜４９．５モル％、酸化銅をＣｕＯ換算で４〜１６．０モル％、酸化亜鉛をＺｎＯ換算で１９．０〜２５．０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０．５〜２質量％、酸化コバルトをＣｏＯ換算で０．３５〜２質量％含有することを特徴とするフェライト組成物。【選択図】図１
