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.
