Soft M-type hexaferrite for very high frequency miniature antenna applications
We have studied soft M-type BaFe 9.6 Co 1.2 Ti 1.2 O 19 hexaferrite for T-DMB (terrestrial digital media broadcasting) antenna applications. The effect of magneto-dynamic properties on antenna size, bandwidth, and radiation efficiency was investigated. The soft M-type BaFe 9.6 Co 1.2 Ti 1.2 O 19 hex...

µ
of the Co/Ti-substituted BaM were measured to be 4.5 and 0.039 at 200 MHz, respectively. The Wheeler cap method and network analyzer were used to evaluate antenna radiation efficiency and measure return losses, respectively. Our experimental results show that the low-loss Co/Ti-substituted BaM is an excellent soft magnetic material for VHF (very high frequency: 30-300 MHz) miniature antenna applications. |
