Abstract
A dipole antenna structure that includes a sheet of metal that forms elements of a dipole antenna. The sheet of metal includes a first arm, and a second arm connected to the first arm, and formed substantially co-planar with, and non-parallel to, the first arm. The sheet of metal further includes at least one impedance matching element connected to the first arm and the second arm, where the at least one impedance matching element is formed in the sheet of metal at an angle relative to a plane that coincides with the substantially co-planar first and second arms.
Claims20
A dipole antenna structure, comprising:
- a sheet of metal that forms elements of a dipole antenna comprising:
- a first dipole arm tuned to a first frequency band;
- a second dipole arm, tuned to a second frequency band, connected directly to the first dipole arm and formed substantially co-planar with, and at a first angle to, the first dipole arm;
- and
- at least one impedance matching element coupled to the second dipole arm, wherein the at least one impedance matching element is formed in the sheet of metal at a second angle relative to a plane that coincides with the substantially co-planar first and second dipole arms,
- wherein a portion of the sheet metal that forms the at least one impedance matching element also forms a cantilevered structure that connects to the second dipole arm such that the first dipole arm and the second dipole arm are cantilevered away from a printed circuit board mounting point of the dipole antenna structure.
An antenna, comprising:
- a metal structure formed to produce:
- a first arm formed as a first planar member of the metal structure to resonate at a first frequency band;
- a second arm formed as a second planar member of the metal structure to resonate at a second frequency band, wherein the second arm is co-planar with, connected directly to, and formed at a first angle to, the first arm;
- and
- a cantilevered structure, formed in the metal structure at a second angle relative to the co-planar first arm and second arm, that connects to the second arm and cantilevers the first arm and the second arm outwards away from an edge of a printed circuit board to which the antenna connects,
- wherein the cantilevered structure comprises at least one of an antenna impedance matching element, a feed connection, or a ground connection of the antenna.
A multi-band dipole antenna, comprising:
- a metal structure that forms elements of the dipole antenna comprising:
- a first dipole arm formed in the metal structure and tuned to a first frequency band;
- a second dipole arm formed in the metal structure and tuned to a second frequency band, wherein the second dipole arm is formed co-planar with, and non-parallel to, the first dipole arm;
- and
- a cantilevered structure, formed in the metal structure adjacent the first and second dipole arms,
- wherein the cantilevered structure further comprises:
- an arm support beam formed in the metal structure at a first angle relative to a bottom surface of the second dipole arm,
- a cantilever beam formed in the metal structure at a second angle relative to a surface of the arm support beam,
- a feed line formed in the metal structure to connect to the cantilever beam, and
- a ground line formed in the metal structure to connect to the arm support beam.
