    • A wideband slot-loop antenna is described which comprises a generally planar loop element having a generally rectangular outer perimeter and a slot defining an inner perimeter, the mid portion of the slot-loop structure providing a major radiation portion of the antenna; a loading structure extending from one end of the slot, the loading structure for top loading the radiation portion; and an impedance matching portion for coupling a feed to the major radiation portion. The antenna also includes distributed matching patches. The distributed matching patches realize extra wideband performance. The antennas in the present invention are suitable for various wireless communications, such as PCS, Cellular Telephone, wireless data and computer network.
    • 描述了一种宽带槽环天线,其包括具有大致矩形的外周边和限定内周的槽的大致平面的环形元件,所述槽环结构的中间部分提供天线的主辐射部分; 从槽的一端延伸的装载结构,用于顶部装载辐射部分的装载结构; 以及用于将馈送耦合到主辐射部分的阻抗匹配部分。 天线还包括分布式匹配补丁。 分布式匹配补丁实现了额外的宽带性能。 本发明中的天线适用于各种无线通信,例如PCS,蜂窝电话,无线数据和计算机网络。

    • In accordance with a non-limiting aspect, a mobile wireless communications device includes a housing, at least one circuit board carried by the housing, radio frequency (RF) circuitry, and a processor. An antenna is operative with the RF circuitry. A charging circuit charges a battery carried by and powers the device and includes at least one charging contact carried by the housing and configured for engaging an external charging cradle when connected thereto. It includes an internal connector extending to at least one circuit board and connecting to the charging circuitry. An RF filter includes a ferrite material surrounding at least a portion of the internal connector to minimize RE coupling from the at least one charging contact to the antenna and reduce transmitter harmonics emission and receiver de-sense.
    • 根据非限制性方面,移动无线通信设备包括壳体,由壳体承载的至少一个电路板,射频(RF)电路和处理器。 天线与RF电路一起工作。 充电电路对由该设备承载的电池充电并且为该设备供电,并且包括由壳体承载的至少一个充电触点,并且被配置成用于当与其连接时接合外部充电座。 它包括延伸到至少一个电路板并连接到充电电路的内部连接器。 RF滤波器包括围绕至少一部分内部连接器的铁氧体材料,以最小化从至少一个充电触点到天线的RE耦合,并减少发射机谐波发射和接收机解读。
