Multi-band base station antennas having broadband decoupling radiating elements and related radiating elements

A base station antenna, comprising:

• a first linear array of radiating elements that is configured to transmit radio frequency (“RF”) signals in a first frequency band;
• a second linear array of radiating elements that is configured to transmit RF signals in a second frequency band;
• a third linear array of radiating elements that is configured to transmit RF signals in a third frequency band,
• wherein the first linear array is mounted between the second linear array and the third linear array,
• wherein the first linear array of radiating elements includes a first radiating element that has a first dipole that extends along a first axis, the first dipole including a first dipole arm and a second dipole arm, and a second dipole that extends along a second axis, the second dipole including a third dipole arm and a fourth dipole arm,
• wherein the first dipole arm is configured to be more transparent to RF signals emitted by a second radiating element that is the radiating element in the second linear array that is closest to the first dipole arm than it is to RF signals emitted by one of the radiating elements in the third linear were that radiating element mounted in the position of the second radiating element.
