Abstract: Waveguide antennas and corresponding manufacturing methods are described herein. These include dual-linear antennas. These dual-linear antennas provide efficient transmission and reception of two radio-frequency signals that may be polarized in orthogonal orientations. The electrically conducting features within the dual-linear antenna are manufactured using standard printed circuit board (PCB) manufacturing technology. The final outer form of the dielectric waveguide antenna may be machined by turning on a lathe or similar mechanical technique, cast in a mold, or injection molded, and the final outer form is accurately aligned and registered to the radio-frequency features of the PCB. The dual-polarized antenna device may include multiple pairs of parallel slot antennas fabricated within a planar printed circuit.

Abstract: An electronic device may include communications circuitry, sensing circuitry, and a set of antennas having first and second feeds for covering different polarizations. The communications circuitry may transmit signals with a first polarization using each of the antennas and may concurrently transmit signals with a second polarization using all but a selected one of the antennas. The sensing circuitry may concurrently transmit sensing signals with the first polarization using one of the antennas and may receive sensing signals with the second polarization using the selected antenna. The sensing signals may include chirp signals generated to include muted periods that correspond to a range of frequencies that overlap frequencies at which the wireless circuitry is subject to radio-frequency interference. This may allow for concurrent wireless communications and sensing operations without interference between the communications circuitry and the sensing circuitry.

Abstract: A wireless communication device for use in a load control system for controlling one or more electrical loads may comprise a counterpoise, a first and second antennas, a RF communication circuit and a control circuit. The two antennas may be oriented differently and spaced apart from each other. For example, the first antenna may extend perpendicularly from the counterpoise while the second antenna extends in a plane substantially parallel to the counterpoise. The first antenna may extend from the counterpoise at a point substantially central to the counterpoise while the second antenna may extend along a perimeter of the counterpoise. The RF communication circuit may transmit wireless signals via the first and second antennas. The control circuit may cause the RF communication circuit to transmit a first wireless signal in a first time slot and a second wireless signal in a second time slot.

Abstract: A three element slot-based antenna which includes a dielectric circuit board, a metallic layer, a sensing antenna, a first narrow band antenna, a second narrow band antenna, a first tapered transmission line, a second tapered transmission line, a first microstrip transmission line and a second microstrip transmission line. The sensing antenna is a semi-hexagonal slot-line loop whereas each of the first narrow band antenna and the second narrow band antenna are formed as a semi-elliptical slot-line loop having an E-shaped base in the metallic layer. The first tapered transmission line and the second tapered transmission line is connected to first feed port and second feed port, respectively. The first microstrip transmission line and the second microstrip transmission line are connected to third feed port and fourth feed port, respectively. The antenna resonates with circular polarization in an ultra-high frequency sub-GHz responsive to input signal at each feed port.

Abstract: Ultra-Wideband (UWB) technology is a wireless technology for the transmission of large amounts of digital data as modulated coded impulses over a very wide frequency spectrum with very low power over a short distance. However, to support their deployment in a wide range of applications it would be beneficial to provide solutions which: exploit multiple directive antennas oriented in different directions to ensure spatial filtering of undesired signals and increase signal strength; exploit dynamic configuration of the multi-pulse bundles employed to transmit the bits/symbols within the packets to enhance link quality of service; exploit dynamic configuration of the band or bands which the transmitter operates upon; and exploit antenna sub-systems providing omnidirectional radiation patterns with implementations offering filtering and balun functions with small footprint and low cost.
