Abstract
Radiating elements for a base station antennas include a first dipole radiator that extends along a first axis, the first dipole radiator including a first dipole arm and a second dipole arm. At least one of the first and second dipole arms includes first and second spaced-apart conductive segments that are connected to each other via both a first inductor and a second inductor that are electrically in parallel with one another.

A radiating element for a base station antenna, comprising:
- a first dipole radiator that includes a first dipole arm and a second dipole arm,
- wherein the first dipole arm includes first and second widened conductive segments that are spaced-apart from each other and that are connected by both a first conductive path and by a second conductive path that is separate and distinct from the first conductive path, wherein an average width of each of the first and second widened conductive segments is at least four times an average width of the first conductive path and at least four times an average width of the second conductive path,
- wherein the radiating element is provided in combination with the base station antenna, the base station antenna further comprising a higher-band radiating element that is positioned adjacent the radiating element, wherein a first electrical length of the first conductive path and a second electrical length of the second conductive path are selected so that currents induced by radio frequency signals in an operating frequency band of the higher-band radiating element on the first dipole radiator that pass through the first and second conductive paths experience different respective first and second phase shifts.
A radiating element for a base station antenna, comprising:
- a first dipole radiator that includes a first dipole arm and a second dipole arm,
- wherein the first dipole arm includes first and second widened conductive segments that are physically and electrically connected to each other by both a first meandered trace section that has a first length and a second trace section that has a second length that is different from the first length, and
- wherein the first meandered trace section and the second trace section are electrically connected in parallel.
A radiating element for a base station antenna, comprising:
- a first dipole radiator that extends along a first axis, the first dipole radiator including a first dipole arm and a second dipole arm,
- wherein the first dipole arm includes first and second spaced-apart conductive segments that are connected to each other via both a first conductive path and a second conductive path that are electrically connected in parallel with one another, and the second dipole arm includes third and fourth spaced-apart conductive segments that are connected to each other via both a third conductive path and a fourth conductive path that are electrically connected in parallel with one another.
