    • A magnetic core member, an antenna module, and a mobile communication terminal having the same, wherein both an improvement of the communication characteristic of antenna coils and a sufficient electromagnetic shielding function from a shield plate can be achieved at the same time. A magnetic core member (4), in which soft magnetic powder (31) has been filled into an insulating material (30), is located between an antenna substrate on which antenna coils (11,12) have been provide and a conductive shield plate (3). The magnetic core member (4) has a two-layer structure comprising first (4A) and second (4B) layers, with the first layer (4A) having a smaller filling rate of soft magnetic powder (31) than the second layer (4B), whereby the magnetic core member (4) can exhibit different magnetic characteristics on a first surface (4a) opposed to the antenna substrate (2) and on a second surface (4b) opposed to the shield plate (3).
    • 一种磁芯部件,天线模块以及具有该磁芯部件的移动通信终端,能够同时实现天线线圈的通信特性的提高和屏蔽板的充分的电磁屏蔽功能。 其中已经将软磁性粉末(31)填充到绝缘材料(30)中的磁芯构件(4)位于已经提供有天线线圈(11,12)的天线基板和导电屏蔽板 (3)。 磁芯部件(4)具有包括第一(4A)和第二(4B)层的双层结构,其中第一层(4A)具有比第二层(4B)更小的软磁性粉末(31)的填充率 ),由此磁芯构件(4)在与天线基板(2)相对的第一表面(4a)上和与屏蔽板(3)相对的第二表面(4b)上可以表现出不同的磁特性。
