Base station antenna and multiband base station antenna

A multiband base station antenna, comprising:

• a first array including a first radiating element that is configured to operate in a higher frequency band;
• a second array including a tri-pole radiating element that is configured to operate in a lower frequency band, the tri-pole radiating element including first to third radiating arms that extend substantially parallel to a main surface of the base station antenna, wherein the radiating arms are each oriented such that a substantially right angle is formed either between extension directions of the first and second radiating arms or between extension directions of the second and third radiating arms, and at least one of the first to third radiating arms extends substantially in a direction that is parallel to a longitudinal axis of the base station antenna;
• and
• a third array including a cross dipole radiating element that is configured to operate in the lower frequency band,
• wherein at least one dipole arm of the cross dipole radiating element is configured to reduce a current that is excited in the at least one dipole arm in the higher frequency band.
