Abstract

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.

Description

technical field [0001] The present invention relates to antennas used in communication terminals. Specifically, the present invention relates to a Y-type hexagonal ferrite, a method for manufacturing the Y-type hexagonal ferrite, and an antenna device using the Y-type hexagonal ferrite. Background technique [0002] Current wireless communication systems provide various multimedia services including Global Positioning System (GPS) based services, Bluetooth based services, Internet based services, and the like. In order to smoothly provide such services, high-rate data transmission is required to support a large amount of multimedia data. One way to meet the above requirements is to improve the performance of antennas used in communication terminals. [0003] According to the market demand for improved mobility or portability of communication terminals, there is a growing trend to make such terminals smaller, thinner, lighter and have more functions. Based on the above, th...
