  • Dipole antenna with parasitic elements
    Patent number: 4812855
    Abstract: A dipole antenna system includes a driven dipole element and two parallel parasitic dipole elements equally spaced from the driven dipole element. Dual polarization can also be achieved by using two such systems arranged orthogonally.

  • Parasitically coupled, complementary slot-dipole antenna element
    Patent number: 4710775
    Abstract: A parasitically coupled, complementary slot dipole antenna element includes a driven, cavity-backed slot antenna element and a parasitic dipole element transverse to the slot of the cavity-backed slot antenna element. The cavity-backed slot and parasitic dipole antenna elements resonate at about the center frequency of the excitation signals supplied to the cavity-backed slot antenna element in order to generate a relatively symmetrical electromagnetic signature and an increased bandwidth.
