Abstract: A feed network includes an adjustable electromechanical phase shifter that comprises a main printed circuit board and a phase shifting unit. The adjustable electromechanical phase shifter is configured to shift the phase of an RF signal that is input to the feed network and provide the phase shifted RF signal to at least one radiating element that is positioned on a first side of a reflector of an antenna, where the phase shifting unit is formed on the surface of a first side of the main printed circuit board, and the first side of the main printed circuit board is a side that is closer to the at least one radiating element, and the main printed circuit board is positioned on the first side of the reflector.

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: 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.
