摘要： Radiating elements for a base station antennas include a first dipole radiator that extends along a first axis, the first dipole radiator including a first dipole arm and a second dipole arm. At least one of the first and second dipole arms includes first and second spaced-apart conductive segments that are connected to each other via both a first inductor and a second inductor that are electrically in parallel with one another.

摘要： A box dipole radiating element uses a compact quad arrangement of substantially coplanar radiating arms to support slant-polarized radiation, in response to differential-mode currents generated along four sides thereof and in response to common-mode currents, which may be generated in substantially the same plane as the differential-mode currents. A feed signal routing network is provided, which includes a feed signal routing substrate on portions of the radiating arms, first through fourth signal traces on a forward face of the substrate, and first through fourth ground plane segments on a rear face of the substrate. These first through fourth ground plane segments are capacitively coupled to the radiating arms. Each of the signal traces receives a corresponding feed signal, and spans a corresponding air gap between a pair of the radiating arms.

摘要： 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.
