Ultra-wideband radiating elements for multiband antennas

A radiating element, comprising:

• a feed stalk;
• a radiator unit mounted on a forward end of the feed stalk, the radiator unit comprising a first dipole radiator that comprises a first dipole arm and a second dipole arm and a second dipole radiator that comprises a third dipole arm and a fourth dipole arm;
• and
• a coupling ring that has an outer perimeter that has a first shape when viewed from the front and a central opening that has a second shape when viewed from the front,
• wherein the second shape is different than the first shape.

A radiating element, comprising:

• a radiator unit that comprises a first dipole radiator that comprises a first dipole arm and a second dipole arm and a second dipole radiator that comprises a third dipole arm and a fourth dipole arm;
• wherein the first dipole arm comprises:
• a first metal pad;
• a first metal trace that extends outwardly from a first side of the first metal pad;
• a second metal trace that extends outwardly from a second side of the first metal pad, the second side opposite the first side;
• and
• a second metal pad that is positioned outwardly of the first metal pad and electrically connected to the first metal pad through the first and second metal traces.
