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.

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: A base station antenna includes a radiating element that extends forwardly from a backplane and that is configured to transmit and receive signals in the 5.15-5.25 GHz frequency band and a radio frequency lens that is mounted forwardly of the radiating element. The RF lens is configured to re-direct a portion of an RF signal emitted by the radiating element downwardly so that a first peak emission of RF energy through a combination of the radiating element and the RF lens at elevation angles that are greater than 30° from a boresight pointing direction of the radiating element is less than a second peak emission of RF energy through the combination of the radiating element and the RF lens at elevation angles that are less than −30° from the boresight pointing direction of the radiating element.

Abstract: The present invention provides a phase shifter assembly for an array antenna, comprising: a first level phase shifter, wherein the first level phase shifter is configured to control the phases of a plurality of sub-arrays of the array antenna, where each sub-array comprises one or more radiating elements; a second level phase shifter, wherein the second level phase shifter is configured to proportionally change the phases of the radiating elements in the corresponding sub-arrays; and a power divider, wherein the power divider is connected between the first level phase shifter and the second level phase shifter. The phase shifter assembly has the advantages of both a distributed phase shifter network and a lumped phase shifter network. Specifically, the phase shifter assemblies can independently control the phases of the radiating elements in the array to obtain better sidelobe suppression. Further, phase control parts of the phase shifter are concentrated within a certain physical space range, so the size of the phase shifter assembly may be greatly decreased, and the cost may be greatly reduced, as compared with a conventional distributed phase shifter assembly design.
