  • Patent number: 11251533
    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.

  • Publication number: 20130314288
    Abstract: An integrated differential high power amplifier-radiator array that overcomes the prior art impedance match issues is described. An impedance matching balun is used to feed a high output impedance, differential HPA, which in turn drives a wide band radiator or array of radiators having a matching input impedance to provide a highly efficient, compact transmit system. In one exemplary embodiment, the HPA may be a high impedance Class-B HPA configured as a push-pull cascode amplifier. A high impedance isolator or circulator may be used between the HPA and the radiator. One of ordinary skill in the art will readily appreciate that a receive implementation, using a properly matched low noise amplifier in place of the HPA, is also possible. Similarly, with the addition of a slotline circulator, transceiver operation is also attainable with the addition of an impedance matched receive chain.

    Abstract: A superluminal antenna element integrates a balun element to better impedance match an input cable or waveguide to a dielectric radiator element, thus preventing stray reflections and consequent undesirable radiation. For example, a dielectric housing material can be used that has a cutout area. A cable can extend into the cutout area. A triangular conductor can function as an impedance transition. An additional cylindrical element functions as a sleeve balun to better impedance match the radiator element to the cable.

  • Patent number: 8456375
    Abstract: In a dielectrically-loaded multifilar helical antenna, a conductive phasing ring is arranged between and couples together feed nodes and the helical radiating elements. The phasing ring includes an annular conductive path having an electrical length equivalent to a full wavelength at the operating frequency so as to be resonant at that frequency. The helical elements are coupled to the outer periphery of the phasing ring at respective spaced apart coupling locations. The helical elements may include open-circuit or closed-circuit elongate conductive tracks, or a combination of both. In the case of the helical elements being closed-circuit tracks, these tracks are interconnected by a second resonant ring, which is resonant at the same frequency as or a different frequency from the first resonant ring. The invention is applicable to both end-fire and back-fire helical antennas.
