| ABSTRACT |
|
To develop mobile phone antenna modules, glass-ceramics composites that are 20∼80 dielectric constant materials which has been fabricated. The glass-ceramics composites were based in the BNT (BaO-Nd$_2$O$_3$-TiO$_2$), and properties-a sintering and dielectric property-were investigated in its composites according to the $K_2$O-CaO-P$_2$O$_{5}$ system glass frits. The prepared ceramics were sintered at 900∼120$0^{circ}C$ with the glass frit contents ranging from 10 to 40 wt%. The shrinkage and relative density grew into increasing glass frits and sintering temperature. Sintered composites showed the tendency that the dielectric constant ($varepsilon$$_{r}$) and quality factor (Q${times}$f) decreased in increasing glass frits and sintering temperature.e.. ጊᔀ Ѐ㘴〻Ԁ䭃䑎䷙᜕ಆ 6㐰⸵㬅K䍄乍 |
