US Patent 11962102 Multi-band stamped sheet metal antenna

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.
