Y-TYPE HEXAGONAL FERRITE, FABRICATION METHOD THEREOF, AND ANTENNA APPARATUS USING THE SAME |
摘要 |
A method of making Y-type hexagonal ferrite and an antenna using the same are provided. Y-type hexagonal ferrite includes a base ferrite composed of iron oxide, barium carbonate and cobalt oxide, and silicate glass ranging from 0.5 to 5 weight percent added to 100 weight percent of base ferrite. An antenna apparatus includes a magnetic carrier and an antenna pattern formed thereon. The magnetic carrier is formed of such Y-type hexagonal ferrite, and the antenna pattern resonates in a specific frequency band when electric power is supplied. To fabricate the Y-type hexagonal ferrite, a calcination process is performed in which iron oxide, barium carbonate and cobalt oxide are combined into base ferrite at a given calcination temperature after being mixed. A sintering process is performed to sinter the base ferrite and the silicate glass at a given sintering temperature which is lower than the calcination temperature after adding the silicate glass to the base ferrite. |
