摘要： A RF distribution network for split beam antennas is disclosed. The split beam antennas may include four-column cross-polarized user specific tilt antennas implemented in a 4T4R or 4T8R system. A RF distribution network may provide transmit signals from transmitters to antennas while also providing receive signals from the antennas. A RF distribution network may include 180° 6.9 dB combiners coupled to the antennas and also coupled 90° hybrids. A 180° 6.9 dB combiner may include a transmission network with transmission lines in a 4T4R system. Alternatively, a 180° 6.9 dB combiner may include a transmission network with transmit and receive filters in a 4T8R system. The transmission network couples the transmit filter and two filters by at least three λ/4 transmission lines. A transmission network provides isolation between two receive signal paths and, at the same time, provides power splitting of transmitter power to two duplexed transmit signal paths.

摘要： Using high-beam and low-beam transmission signals that have different antenna tilts, different beam-widths, and different polarizations than one another may provide performance advantages in wireless networks. The high-beam transmission signal and the low-beam transmission signal may have orthogonal polarizations. For example, the high-beam transmission signal and the low-beam transmission signal may be linearly polarized signals having different electromagnetic field (E-field) polarization angles with respect to the y-axis, e.g., +/- forty-five degrees with respect to a vertically polarized wave. As another example, the high-beam transmission signal may be a vertically polarized signal, and the low-beam transmission signal may be a horizontally polarized signal, or vice-versa. In addition to having orthogonal polarizations, the low-beam transmission signal may have a greater antenna beam down-tilt angle, and a wider beam-width than the high-beam transmission signal.

摘要： Disclosed herein is a dual-feed dual-polarized antenna element and a method for manufacturing the same. An embodiment dual-polarization antenna element includes four radiating elements and eight feed ports. The four radiating elements are arranged in a co-planar diamond pattern. The neighboring elements of the four radiating elements form four shared-element dipole antenna elements. Each of the four radiating elements is shared between two cross-polarized dipole antenna elements of the four shared-element dipole antenna elements. The eight feed ports are arranged in four cross-polarized dual-feed pairs respectively disposed on the four radiating elements. Each feed port of the four cross-polarized dual-feed pairs is operable to respectively excite one of the four radiating elements for a cross-polarized one of the four shared-element dipole antenna elements.
