    Abstract: A broad band diversity antenna system comprises a system of log periodic antennas (LPA) and dipole antennas. Two LPAs form a balanced dipole by feeding the back ends of the LPA. The feed is improved by the addition of a balun to ensure RF balance. Because a dipole only requires narrow bandwidth, a simple balun is constructed from coax cable or a transmission line, thus providing low cost construction.

    Abstract: Disclosed are improved antenna structures, systems, and methods of manufacturing. In an embodiment, low-cost internal 2G/5G antennas have flat metal dipole construction, which can include a stiffener. External embodiments include quad dipole antenna structures, with broadside or corner arrays. Isolated multi-band center or end-fed dipole antennas can include single-sided PCB or metal-only structures, for operation with at least two distinct frequencies, and can provide RF isolation, such as with an RF trap or a Balun system. Embodiments of non-DC path or pass-through dual band antennas feature trap structures, along with discrete or distributed matching, and can provide a DC feed path for LEDs. Low profile and flat vertically polarized omni-directional antennas, such as for operation at 915 MHz, include an open slot driven cavity. Stacked 2G/5G antenna structures provide axial symmetry between quadrants. Improved construction methods and antenna structures include enhanced thin metal components and low cost, crimp-only construction methods.

    Abstract: Various embodiments disclose systems and methods for employing a Sub1G signal (e.g. a signal in the range of approximately 500 Mhz or 800 mHz) for use with internal and/or external components of various user devices. The Sub1G region may provide a path loss advantage over traditional 2.4 and 5 Ghz systems because of the lower frequency in free-space path loss model. Sub1G may also present less interference compared to 2.4 GHz (e.g., better QoS for applications such as VOIP, Gaining, etc.). In some of the disclosed embodiments, Sub1G may be employed using current 2.4G or 5G Wireless LAN chipset with RF Up/Down Converters. In some embodiments, the Sub1G approach may be used to create a Long Range Bridge, Long Range Extender, Long Range Client, Long Range Hotspot, etc.

    Abstract translation: 各种实施例公开了用于使用与各种用户装置的内部和/或外部组件一起使用的Sub1G信号（例如，大约500Mhz或800mHz的信号）的系统和方法。 由于自由空间路径损耗模型的频率较低，Sub1G区域可能比传统的2.4和5 GHz系统提供路径损耗优势。 与2.4GHz相比，Sub1G还可以呈现更少的干扰（例如，对于诸如VOIP，Gaining等应用的更好的QoS）。 在一些所公开的实施例中，可以使用具有RF上/下转换器的当前2.4G或5G无线LAN芯片组来采用Sub1G。 在一些实施例中，Sub1G方法可用于创建长距离桥，长距离扩展器，远程客户端，远程热点等。
