Abstract
Methods and apparatus for providing a wideband dual differential current loop radiator. In embodiments, a radiator includes first and second dipole pairs with first and second differential conductor pairs providing differential signals to the first and second dipole arms. The radiator may include a cavity, which can be filed with air, in at least a portion of a feed layer. The dipoles may have a coincident phase center.
