Abstract
A dual polarization antenna includes a substantially pyramidal configured substrate having opposing walls. An antenna element is carried at each wall such that opposing pairs of antenna elements define respective antenna dipoles and provide dual polarization.
Claims16
A dual polarization antenna element comprising:
- a substantially pyramidal configured substrate having opposing and intersecting walls;
- and
- a monopole element carried at each wall such that opposing pairs of monopole elements define respective antenna dipoles and provide dual polarization, wherein said monopole elements are operative together as a balanced circuit, and further comprising diagonal feed sections defined by intersecting walls, and transmission lines carried by said feed sections and interconnecting each monopole element to form a dipole, and a feed launch formed at each feed section as an extension of the pyramidal substrate as a base configured to be surface mounted to a board.
A phased array antenna comprising:
- a substrate comprising a ground plane and a dielectric layer adjacent thereto;
- and
- a plurality of dual polarization antenna elements carried by the substrate, each comprising
- a substantially pyramidal configured substrate having opposing and intersecting walls;
- and
- a monopole element carried at each wall such that opposing pairs of monopoles elements define respective antenna dipoles and provide dual polarization, wherein said monopole elements are operative together as a balanced circuit, and further comprising diagonal feed sections defined by intersecting walls, and transmission lines carried by said feed sections and interconnecting each monopole element to form a dipole, and a feed launch formed at each feed section as an extension of the pyramidal substrate as a base configured to be surface mounted to a board.
