  • Patent number: 11916319
    Abstract: Single band and multiband wireless antennas are an important element of wireless systems. Competing tradeoffs of overall footprint, performance aspects such as impedance matching and cost require not only consideration but become significant when multiple antenna elements are employed within a single antenna such as to obtain circular polarization transmit and/or receive. Accordingly, it would be beneficial to provide designers of a wide range of electrical devices and systems with compact single or multiple frequency band antennas which, in addition to providing the controlled radiation pattern and circular polarization purity (where required) are impedance matched without substantially increasing the footprint of the antenna and/or the complexity of the microwave/RF circuit interfaced to them, whilst supporting multiple signals to/from multiple antenna elements in antennas employing them.

  • Patent number: 11670851
    Abstract: Phased arrays to be used for Tx and Rx communications in different frequency bands are disclosed. The phased arrays presented herein are non-uniformly thinned half-duplex phased arrays with dual-band antenna elements. Such phased arrays are “half-duplex” in that they are configured for communication in one direction at a time, i.e., either for Tx or for Rx, while utilizing a common array. Such phased arrays are “with dual-band antenna elements” in that, in addition to using antenna elements configured for Tx or for Rx only, they implement some antenna elements that are configured for both Tx and Rx. Such phased arrays are “thinned” in that they are formed according to a method of optimizing array geometry known as “thinning.” Such phased arrays are thinned “non-uniformly” in that different antenna elements used for Tx may have different numbers of nearest and/or second-nearest neighbor antenna elements used for Rx, or vice versa.

  • Patent number: 11658412
    Abstract: An antenna includes a first element, a second element, and a reactance-adjustable component. The first element receives an excitation current through an electrical connection to an antenna feeder, and the second element generates an induced current through electromagnetic induction of the first element. The reactance-adjustable component is disposed at an end of the first element close to a reference plane, and/or the reactance-adjustable component is disposed at an end of the second element close to a reference plane. The reference plane uses a connection point between the first element and the antenna feeder as an origin point and is perpendicular to an axial direction of the first element. The reactance-adjustable component has an adjustable reactance value and is configured to adjust a phase difference between an excitation current and an induced current, where the phase difference has an association relationship with a target angle of radiation of the antenna.

  • Patent number: 11588251
    Abstract: An antenna feed for a stackable antenna system includes a polarization converter that continuously surrounds an omnidirectional antenna. Electromagnetic radiation emitted by the omnidirectional antenna and having an initial polarization passes through the first polarization converter, which converts the initial polarization into a non-vertical linear polarization. A feedline located outside of the first polarization converter forms a helix that wraps around the first polarization converter such that it runs perpendicularly to the non-vertical linear polarization. When the width of the feedline is sufficiently small, electrons in metal of the feedline will not be excited by the radiation, and the radiation will transmit through the feedline with minimal impact on the omnidirectional antenna's gain profile. The feedline may be used to feed a second antenna located vertically above the omnidirectional antenna.
