Radiating elements having dipole arms with cloaked dielectric loading elements and base station antennas including such radiating elements

A base station antenna, comprising:

• a second radiating element that is configured to operate in a second frequency band;
• a first radiating element that is configured to operate in a first frequency band that is different from the second frequency band, the first radiating element comprising a first radiator and a first dielectric loading element for the first radiator, the first dielectric loading element including a first metal pattern that is not part of the first radiator and that is configured to reduce the impact of the first dielectric loading element on radio frequency (“RF”) energy emitted by the second radiating element.

A radiating element that is configured to operate in a first frequency band, comprising:

• a first dipole radiator that has a first dipole arm and a second dipole arm;
• a second dipole radiator that has a third dipole arm and a fourth dipole arm wherein one or more dielectric blocks having dielectric constants of at least 4.0 are positioned adjacent the first through fourth dipole arms to dielectrically load the first through fourth dipole arms, and the dielectric blocks are cloaked with respect to radio frequency (“RF”) energy in a second frequency band that is different from the first frequency band.
