  • Multiband antenna
    Patent number: 12113298
    Abstract: Antenna includes at least one first resonant cavity and a second resonant cavity, each resonant cavity being closed by a base at one end and including a radiating element superimposed on the base of the resonant cavity, the radiating element of the first cavity being able to transmit a signal on a first frequency band and the radiating element of the second cavity being able to transmit a signal on a second frequency band separate from the first frequency band, characterized in that a first distance between the base and radiating element of the first cavity differs from a second distance between the base and radiating element of the second cavity.
    Type: Grant
    Filed: August 29, 2022
    Date of Patent: October 8, 2024

  • Antenna with improved coverage over a wider frequency band
    Patent number: 11658421
    Abstract: The invention relates to an antenna comprising a radiative antenna element able to emit a signal in at least two disjoint frequency bands and a waveguide covered by the radiative antenna element, comprising two nested resonant cavities, each single-mode or mostly single-mode in a separate frequency band.
