Abstract: Base station antennas include a reflector, a first linear array of radiating elements extending forwardly from the reflector, the radiating elements in the first linear array configured to operate in a first frequency band, and a second linear array of radiating elements extending forwardly from the reflector, the radiating elements in the second linear array configured to operate in the first frequency band. These antennas further include an isolation wall that is positioned in between the first linear array of radiating elements and the second linear array of radiating elements. This isolation wall comprises at least one partially reflective surface that is configured to reflect, on average as a function of frequency, between 20% and 80% of incident radiation in the first frequency band.

Abstract: Active antenna units and/or base station antennas are provided that include a reflector body with heat dissipation structures that can be directly exposed to environmental conditions during use. The heat dissipation structures have frequency selective surfaces and can be formed of sheet metal or provided as separate extruded or die cast members that can be coupled to the reflector body.

Abstract: Base station antenna units include a first and second base station antennas that have respective first and second housings. The first housing includes a top end cap and the second housing includes a bottom end cap. A jumper cable that includes a first connector port is mounted in one of the top end cap or the bottom end cap, and a second connector port that is configured to mate with the first connector port is mounted in the other one of the top end cap or the bottom end cap. A longitudinal axis of the first connector port extends in a vertical direction and a longitudinal axis of the second connector port extends in the vertical direction.

Abstract: A base station antenna includes an internal radome and a multi-column antenna array antenna. The internal radome can be configured with a plurality of columns, each having an outwardly projecting peak segment and each neighboring column of the internal radome can be separated by a valley. Each outwardly projecting peak segment(s) is oriented to project toward a front of the base station antenna and is positioned medially aligned over a respective column of the multi-column antenna array to thereby reduce mutual coupling of respective elements and/or columns of elements and/or provide a common near field environment for each element and/or each column.

Abstract: A dual-polarized radiating element includes a first dipole radiator that has a first dipole arm that generally extends along a first axis and a second dipole arm that generally extends along a second axis that is different from the first axis, and a second dipole radiator that has a third dipole arm that generally extends along the first axis and a fourth dipole arm that generally extends along a third axis that is different from the first axis. At least one of the first through fourth dipole arms may be a cloaked dipole arm that include inductive elements that are configured to suppress currents in a higher frequency band.
