Abstract: A cross-dipole radiating element includes first and second polymer-based coplanar waveguide feed stalks, and first and second pairs of polymer-based radiating arms, which are supported by and electrically coupled to the first and second coplanar waveguide feed stalks. These polymer-based feed stalks and radiating arms are configured as a unitary polymer substrate, which is selectively metallized to define a cross-dipole radiating element. The first and second feed stalks may be configured as finite grounded coplanar waveguide (GCPW) feed stalks, which are spaced-apart from each other on an underlying polymer base. The unitary polymer substrate may include the polymer base.

Abstract: Base station antennas include a reflector, a first array of cross-polarized radiating elements that are mounted to extend forwardly from the reflector, and a parasitic assembly. The parasitic assembly includes a base that is mounted on the reflector, a horizontal component shaping element, and a forwardly projecting member that projects forwardly from the base that is coupled between the base and the horizontal component shaping element, The horizontal component shaping element may extend substantially parallel to a plane defined by the reflector and may include a proximate side that is directly connected to the forwardly projecting member and a distal side that is opposite the proximate side. The distal side of is only electrically connected to the reflector through the proximate side.

Abstract: An antenna assembly includes a backplane and a polymer substrate mounted over the backplane to define an air gap therebetween. The polymer substrate supports radiating elements comprising a polymer-based waveguide feed stalk and a polymer-based pair of radiating arms supported by and electrically coupled to the waveguide feed stalk. A conductive layer is formed on the polymer substrate such that the conductive layer faces the backplane. A phase shifter including a movable element such as a dielectric member or trombone member may be positioned in the air gap for adjusting the phase of a radiating element or a phase shifter assembly may be positioned to the back side of the back plane.

Abstract: Radiating elements of first and second linear arrays of radiating elements have respective feed stalks that can reside at an angle to provide a balanced dipole arm with an inner end portion laterally offset to be closer to a right or left side of the base station antenna and reflector than an outer end portion that faces a radome of the base station antenna. The feed stalk can include sheet metal legs and printed circuit boards providing an RF transmission line(s).

Abstract: An antenna includes a cross-polarized feed signal network configured to convert first and second radio frequency (RF) input feed signals to first and second pairs of cross-polarized feed signals at respective first and second pairs of feed signal output ports. A feed signal pedestal is provided, which is electrically coupled to the first and second pairs of feed signal output ports, and a patch radiating element is provided, which is electrically coupled by the feed signal pedestal to the first and second pairs of feed signal output ports. This patch radiating element may be capacitively coupled to first and second pairs of feed signal lines on the feed signal pedestal, which are electrically connected to the first and second pairs of feed signal output ports.

Abstract: A base station antenna includes a reflector assembly and a linear array of radiating elements extending forwardly from the reflector assembly. The reflector assembly includes an RF choke that has a choke body and a choke cover. The choke cover at least partially covers a choke body opening so that a choke opening of the RF choke is smaller than the choke body opening.

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 radiating element includes a feed stalk and first through fourth dipole arms. An outer segment of the first dipole arm and an outer segment of the second dipole arm are configured to together form a first radiating structure that radiates at a first polarization, an outer segment of the third dipole arm and an outer segment of the fourth dipole arm are configured to together form a second radiating structure that radiates at the first polarization, and first and second inner portions of each of the first through fourth dipole arms are configured to together form a third radiating structure that radiates at the first polarization when a first RF signal is fed to the radiating element.

Abstract: Base station antennas are provided herein. A base station antenna includes consecutive first, second, third, and fourth columns of radiating elements that are configured to transmit in a first frequency band. In some embodiments, the first and third columns are further configured to transmit in a second frequency band that is different from the first frequency band as a first MIMO pair, and the second and fourth columns are further configured to transmit in the second frequency band as a second MIMO pair. Additionally or alternatively, in some embodiments, the first and second columns are fed together and are further configured to transmit in a second frequency band as a first MIMO pair, and the third and fourth columns are fed together and are further configured to transmit in the second frequency band as a second MIMO pair. Related methods of operation are also provided.
