摘要： Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. In one example, a first subsystem of a first device may determine parameter data for a ranging round (e.g., UWB and/or NB-assisted (NBA) UWB multi-millisecond (MMS) ranging), and transmit the parameter data to a second subsystem of the first device. The parameter data may indicate a first time associated with a first time domain for performing ranging. The second subsystem may determine a second time based on the first time, whereby the second time is associated with a second time domain for performing NB signaling (e.g., via a Bluetooth Low Energy (BLE) protocol). The first device may transmit via an NB signal an advertisement packet that indicates the second time. The first device may then initiate the ranging round at the first time.

摘要： An underground transmitter can be configured for use with a drill head and configured for wireless communication. The underground transmitter can include a control circuitry and a multi-coil antenna assembly. The control circuitry is configured for transmitting data associated with an operation of the drill head. The multi-core antenna can include an antenna core and a plurality of distinct wire coils. The plurality of distinct wire coils can be positioned proximate (e.g., around) the antenna core, with the distinct wire coils each having a different inductance associated therewith and thereby capable of transmitting in a separate frequency range. The control circuitry can be selectably coupled with the distinct wire coils to control which of the distinct wire coils are activated and thereby generating data signals at a given time.

摘要： A mobile device includes a ground element, a first radiation element, a second radiation element, and a dielectric substrate. The first radiation element has a feeding point. The first radiation element includes a meandering portion. The second radiation element is coupled to the feeding point, and is at least partially surrounded by the first radiation element. A coupling gap is formed between the first radiation element and the second radiation element. The ground element, the first radiation element, and the second radiation element are all disposed on the dielectric substrate. A planar antenna structure is formed by the first radiation element and the second radiation element. The planar antenna structure covers a TETRA (Terrestrial Trunked Radio) frequency band and a GPS (Global Positioning System) frequency band.

摘要： A radio frequency (RF) energy harvesting device including a scalable metamaterial resonator antenna and a rectifying circuit formed on a flexible plastic substrate. The metamaterial resonator antenna includes a metal (e.g., silver) structure that is conformally fixedly disposed (i.e., either printed or deposited/etched) on the flexible substrate and configured to resonate at RF frequencies using primary and secondary antenna segments connected by linking segments such that captured RF signals are generated at two antenna end points that are 180° out-of-phase with each other. The rectifying circuit including additional metal structures that are also printed or otherwise formed on the flexible substrate, and one or more circuit elements that are configured to pass positive voltage pulses from the captured RF signals to an output node. Various metamaterial resonator antenna configurations are disclosed.
