Abstract: A coupling device includes a plurality of couplers. Each coupler includes a transmission main line and a coupling subline. The transmission main line is used for providing an input end and an output end. The coupling subline is coupled with the transmission main line to provide two coupling ends. The coupling subline includes two first parts located on opposite sides of the transmission main line and a second part connected between the two first parts. The coupling sublines of the plurality of couplers are connected in series to provide a first coupling output port and a second coupling output port. The first part of the coupling subline of at least one of the plurality of couplers has a shared section with the second part of the coupling subline of an adjacent one of the plurality of couplers.

Abstract: Antennas include first and second radiating elements that are configured to operate in respective operating frequency bands. The first radiating element includes a first dipole arm that has a first conductive path and a second conductive path that is positioned behind the first conductive path. The first conductive path includes a plurality of first segments and the second conductive path includes a plurality of second segments, where a subset of the first segments overlap respective ones of second segments to form a plurality of pairs of overlapping first and second segments. At least some of the pairs of overlapping segments are configured so that the instantaneous direction of a first current formed on the first segment in response to RF radiation emitted by the second radiating element will be substantially opposite the instantaneous direction of a second current formed on the second segment in response to the RF radiation.

Abstract: A base station antenna includes a column of radiating elements comprising first and second sets of radiating elements, each radiating element being configured to operate in a first frequency band that has first and second sub-bands. The second set of radiating elements is located above and/or below the first set of radiating elements. The antenna further includes a feeding assembly that is configured to feed first RF signals that are in the first sub-band and second RF signals that are in the second sub-band to the column of radiating elements, where the feeding assembly is configured to partially attenuate sub-components of the second RF signals that are fed to the second set of radiating elements more than sub-components of the first RF signals that are fed to the second set of radiating elements.

Abstract: An antenna assembly includes a substrate (52) having front and back surfaces (52a, 52b) thereon and a plurality of through-holes (70) therein, along with a solder pad (68) on the back surface of the substrate. An input cable is also provided, which is attached to the back surface of the substrate. The input cable includes an outer conductor (62), which contacts the back surface of the substrate, and an inner conductor (56), which extends at least partially through a first of the plurality of through-holes and is electrically connected to the solder pad. A metal trace (e.g., 50-ohm trace) is provided on the front surface of the substrate. The metal trace is electrically connected to the solder pad by electrically conductive plating in a second of the plurality of through-holes (see Fig. 6a).
