- 采用传统的固相反应法制得了一种低损耗的Z型铁氧体材料（Sr1Ba2-xBixCo2＋xFe24O41,其中x=0,0.15）,基于此材料设计得到一近似全方向辐射模式,在470～702MHz频段平均增益大于-3dB,且在此频段的辐射效率为33.5%～67.3%的小型化天线,该天线完全满足DVB-H（数字视频广播手持终端传输技术）的应用。
Abstract：A low-loss Z-type hexaferrites（Sr1Ba2-xBixCo2＋xFe24O41 with x=0,0.15） has been developed by means of the conventional solid-state reaction in this paper.The proposed antenna based on this material has an approximately omnidirectional radiation pattern and yields greater than-3dBi average gain in the band of 470 to 702MHz,radiation efficiency of the antenna is 33.5% to 63.7% in the band.These features are suitable for DVB-H（Digital Video Broadcasting-Handheld） applications.
