Abstract: Base station antennas are provided herein. A base station antenna includes a plurality of vertical columns of low-band radiating elements configured to transmit RF signals in a first frequency band. The base station antenna also includes a plurality of vertical columns of high-band radiating elements configured to transmit RF signals in a second frequency band that is higher than the first frequency band. The vertical columns of high-band radiating elements extend in parallel with the vertical columns of low-band radiating elements in a vertical direction.

Abstract: A connection assembly for an antenna includes a printed circuit board and a coaxial cable connected to the printed circuit board. A transmission trace and a solder pad are provided on the printed circuit board. An opening for receiving an end portion of the coaxial cable is also provided in the printed circuit board, and an exposed outer conductor of the end portion extends into the opening, and an exposed inner conductor reaches the solder pad. The connection assembly further includes a ground structure, which is electrically connected to a ground metal layer on a second surface of the printed circuit board, and the ground structure is at least partially arranged on both sides of the exposed inner conductor and/or the exposed outer conductor.

Abstract: A twin beam base station antenna includes a first array that has a plurality of columns of first frequency band radiating elements, the first array configured to form a first antenna beam that provides coverage throughout a first sub-sector of a three-sector base station. The radiating elements in a first of the columns in the first array have a first azimuth boresight pointing direction and the radiating elements in a second of the columns in the first array have a second azimuth boresight pointing direction that is offset from the first azimuth boresight pointing direction by at least 10°. The radiating elements in the second of the columns in the first array are electrically steered.

Abstract: A multi-band radiating array includes a reflector, a plurality of first radiating elements defining a first column on the reflector, a plurality of second radiating elements defining a second column on the reflector alongside the first column, and a plurality of third radiating elements defining a third column on the reflector between the first and second columns. The first radiating elements have a first operating frequency range, the second radiating elements have a second operating frequency range that is wider than the first operating frequency range, and the third radiating elements have a third operating frequency range that is lower than the second operating frequency range. Related radiating elements are also discussed.

Abstract: The present invention relates to a base station antenna, comprising: a plurality of first radiating elements that are arranged as a first vertically-extending array; a plurality of second radiating elements that are arranged as a second vertically-extending array, where the second radiating elements are staggered in the vertical direction with respect to the first radiating elements; wherein phase centers in an azimuth plane for first sub-arrays of the first radiating elements are substantially the same as phase centers in the azimuth plane for respective third sub-arrays of the second radiating elements, and wherein the first sub-arrays each have a first number of first radiating elements and the third sub-arrays each have a second number of second radiating elements, the first number being different than the second number. This can effectively improve the pattern of the base station antenna.

Abstract: Multi-band antennas utilize compact multi-band dipole-type radiating elements having multiple arms, including a front facing arm and a rear facing arm that respectively target higher and lower frequency bands. These higher and lower frequency bands may include, but are not limited to, a relatively wide band (e.g., 1695-2690 MHz) associated with the front facing arm and somewhat narrower and nonoverlapping band (e.g., 1427-1518 MHz) associated with the rear facing arm. The front facing arm may extend on a “front” layer of a multi-layer printed circuit board and the rear facing arm may extend at least partially on a “rear” layer of the printed circuit board. A resonant LC (or CLC) network is provided, which is integrated into the rear facing arm and at least capacitively coupled to the front facing arm. This resonant network advantageously supports low-pass filtering from the front facing arm to the rear facing arm, to thereby support the multiple and nonoverlapping bands.

Abstract: Apparatus include two or more radiating elements connected to a feed network of an antenna, and one or more dummy elements positioned between the two or more radiating elements. The dummy elements are not connected to the feed network of the antenna. Such an arrangement may result in reduced mutual coupling of the two or more radiating elements, and increased antenna performance.
