    • A mobile communication device (1) is provided with an antenna (10) having an antenna element (10a) and a conductive ground element (26) to cooperate with the antenna element. In use, RF currents are generated in the conductive ground element and as a result an oscillating electric field arises. The conductive ground element is arranged in the device (1) such that the point of highest electric field is located away from the region where the earpiece (5) is positioned in order to reduce the emission of the electric field to the ear (12). The conductive ground element (26) may be provided in a conductive layer of the Printed Circuit/Wire Board (24) of the device. The point of highest electric field in a in a conductive layer arises at the end of the physical path near a physical end of the layer, which in a conventional flip-phone typically corresponds to the top of the first hinged body part (2) where the earpiece (5) is also positioned. According to the invention, the layer is serpentine shaped and arranged such that the end of the electrical path of the Printed Circuit/Wire Board is located approximately half a wavelength of the oscillating field away from the area of the earpiece. Alternatively, tracks or wires (27, 28) acting as ground extensions may be connected to the ground plane (26) to move the end of the electrical path and the high electric field away from the region of the earpiece.
    • 移动通信设备(1)设置有具有天线元件(10a)和与天线元件配合的导电接地元件(26)的天线(10)。 在使用中,在导电接地元件中产生RF电流,结果产生振荡电场。 导电接地元件布置在设备(1)中,使得最高电场的点位于远离耳机(5)所在的区域的位置,以便减少对耳朵(12)的电场的发射, 。 导电接地元件(26)可以设置在设备的印刷电路板/导线板(24)的导电层中。 在导电层中的最高电场的点出现在靠近物理端的物理路径的末端,在传统的翻盖电话中通常对应于第一铰接体部分(2)的顶部, 耳机(5)也被定位。 根据本发明,该层是蛇形形状并且布置成使得印刷电路/线路板的电气路径的端部位于远离耳机的区域的振荡场的大约一半的波长处。 或者,用作接地延伸部的轨道或线(27,28)可以连接到接地平面(26),以使电路径的端部和高电场远离耳机的区域。
