Abstract: A base station antenna comprises a reflector assembly and a first radiating element having a first feed stalk and a first radiator. A base of the first feed stalk is adjacent the reflector assembly and the first radiator is adjacent a distal end of the first feed stalk. A center of the first radiator is offset from the base of the first feed stalk in a longitudinal direction that is parallel to a longitudinal axis of the base station antenna.

Abstract: The present disclosure relates to an antenna mounting device for antenna assembly, where the antenna assembly comprises a base station antenna that extends longitudinally and a remote radio unit. The antenna mounting device comprises a first mounting unit, a second mounting unit and an optional third mounting unit. The first mounting unit is configured to pivotally connect a remote radio unit to a foundational component and provide the antenna assembly with a pivot point relative to the foundational component. The second mounting unit is configured to connect the base station antenna to a foundational component in the longitudinal extension direction of the base station antenna, below the first mounting unit and at a distance from the first mounting unit. The second mounting unit has an adjustable effective connection length between the base station antenna and foundational component, where the effective connection length determines the mechanical tilt angle of the antenna assembly. The present disclosure further comprises an antenna system of the antenna mounting device.

Abstract: A multi-antenna mounting device includes: a mounting member to which two or more antennas are fixable; and a tilt angle adjusting mechanism including an upper adjusting component and a lower adjusting component spaced apart along a length direction of the mounting member. The upper adjusting component includes a plurality of tilt angle adjusting holes arranged in a row, one end of the upper adjusting component is connectable to the mounting member, and the other end is connectable to a user's support pole with a fastening element extending through one of the tilt angle adjusting holes. When the fastening element extends through different tilt angle adjusting holes, the multi-antenna assembly has different mechanical tilt angles relative to the support pole. The lower adjusting component includes a first section and a second section. The second section has a predetermined length and the first section is pivotable relative to the second section.

Abstract: Printed circuit boards for a base station antenna include a substrate layer, and a first conductive trace and a second conductive trace which are printed on the substrate layer and cross each other. The first conductive trace has two trace sections separated by the second conductive trace. Adjacent ends of the two trace sections separated by the second conductive trace are connected electrically by a jumper. The jumper has an electrical conductor, is isolated electrically from the second conductive trace and is fixed on the printed circuit board. The electrical conductor and the two trace sections are connected electrically at adjacent ends. The printed circuit board allows flexible wiring of the conductive traces on the printed circuit board.
