    • An electronic device (10) has a screen (12) protecting against radiofrequency electromagnetic fields, wherein the screen is formed by an at least partially conductive cap (12). In order to avoid the formation of a defined conductive connection between the cap (12) and a reference potential, conductive two-dimensional regions (30) of the cap (12) are arranged in electrically insulated fashion at a short distance parallel to at least one two-dimensional region (42) of a conductor (22) of a reference potential. The two-dimensional regions act as a capacitor and a capacitive coupling (12) to the reference potential is produced which eliminates or attenuates radiofrequency electromagnetic interference fields, which enter the electronic device or are emitted from it.
    • 电子设备(10)具有防止射频电磁场的屏幕(12),其中屏幕由至少部分导电的盖(12)形成。 为了避免在盖(12)和参考电位之间形成限定的导电连接,盖(12)的导电二维区域(30)以电绝缘方式布置在平行于至少的短距离 参考电位的导体(22)的一个二维区域(42)。 二维区域用作电容器,并且产生到参考电位的电容耦合(12),其消除或衰减进入电子设备或从其发射的射频电磁干扰场。
