  • MULTI-BAND QUADRIFILAR HELIX SLOT ANTENNA
    Publication number: 20220311145
    Abstract: A quadrifilar helix antenna may comprise a cylindrical body with a conductive layer. The antenna may further comprise a first slot disposed on the cylindrical body, wherein a length of the first slot is proportional to a first wavelength of a first signal. The antenna may further comprise a second slot disposed on the cylindrical body. The antenna may further comprise a first feed line crossing the first slot. The antenna may further comprise a second feed line crossing the second slot.

  • Low profile dual-band quadrifilar antenna
    Patent number: 11183763
    Abstract: A hybrid antenna structure with a ground plane; a supporting body coupled to the ground plane. The supporting body provided with four helical filar extending from the ground plane, ends of each of the filar coupled at a connection point to a periphery of a patch. The filar each having a length of approximately ½ wavelength of a desired operating frequency. Further, the hybrid antenna structure may be configured for self-diplexing by adding a high-band patch upon the patch, spaced apart by a dielectric spacer.
