Abstract: A dual band end fed dipole provides at least two distinct operating frequencies, e.g. 2.45 GHz and 5.5 GHz. Properties of the antenna include low cost to manufacture, e.g. ease of automation; minimal manual labor to manufacture, e.g. reliability; dual band operation; broad bandwidth; good feed line isolation; omnidirectional beam pattern; minimal vertical beam squint; small diameter; and high efficiency. Embodiments of the invention provide a dual band end fed dipole with a low band trap on the feed side that requires minimal manual labor to manufacture because the antenna is formed from a single flat sheet of metal and soldering is replaced with crimping. Minimal dielectric loading is also achieved.

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: An embodiment of the invention provides a transmissive passive repeater having two or more antenna arrays, each array comprised of a plurality of antenna elements. Each antenna array has an associated region. An aperture is defined by the antenna arrays with which energy at respective antenna arrays passes between each of the regions. Another embodiment of the invention provides a reflective passive repeater having an aperture. Energy received at the aperture is reflected back from the aperture. The aperture is configured to provide a conformal mapping between two regions as determined by complex coupling by individual antenna elements.

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. Sub 1G may also present less interference compared to 2.4 GHz (e.g., better QoS for applications such as VOIP, Gaming, 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.
