    • Handheld electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include antenna structures. To accommodate manufacturing variations, the antenna structures and handheld electronic devices may be characterized by performing measurements such as antenna performance measurements. Appropriate antenna adjustments may be made during manufacturing of a handheld electronic device based on the characterizing measurements. An antenna may be formed using an inverted-F design in which an antenna flex circuit is mounted to a dielectric antenna support structure. Cavities in the support may be selectively filled with dielectric material and dielectric patches may be added to the antenna flex circuit to adjust the dielectric loading of the antenna. The length of a ground return path in the antenna may be adjusted by appropriate positioning of an electrical connector within the ground return path.
    • 提供了包含无线通信电路的手持电子设备。 无线通信电路可以包括天线结构。 为了适应制造变化,天线结构和手持电子设备的特征可以是执行诸如天线性能测量的测量。 基于特征测量,可以在制造手持电子设备期间进行适当的天线调整。 可以使用倒置F设计形成天线,其中天线柔性电路安装到电介质天线支撑结构。 载体中的腔可以选择性地填充介电材料,并且可以将介质贴片添加到天线柔性电路中以调节天线的介电负载。 天线中的接地返回路径的长度可以通过电连接器在接地返回路径内的适当定位来调节。
