摘要： A method for radiating a co-located antenna including radiating the co-located antenna using a dual mode, where the co-located antenna has an inter-element spacing of about 1λ and the dual mode includes a TM11 mode and a TM21 mode. The TM11 mode is radiated to generate a TM11 far field pattern, where the TM11 mode has a broadside pattern characterized with a beam peak at broadside and the TM11 mode produces grating lobes in addition to the beam peak at broadside. The TM21 mode is radiated to generate a TM21 far field pattern orthogonal to the TM11 far field pattern, thereby causing the TM21 mode to produce a null at broadside to suppress the grating lobes produced by the TM11 mode.

摘要： An antenna includes a feeding element and at least one non-feeding element. A vertical distance between each non-feeding element and the feeding element falls within a specified threshold, each non-feeding element includes a first conductor that is grounded, a regulator circuit, and a control switch disposed on the first conductor and configured to control the regulator circuit, where the regulator circuit is configured to regulate a current path length of the non-feeding element. The non-feeding element forms a reflector when the regulator circuit is enabled, or the non-feeding element forms a director when the regulator circuit is disabled. A design in which the reflector and the director are compatible is used such that a combination of one feeding element, M directors and N reflectors is implemented for the antenna to achieve a high directive gain and interference suppression capability.

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.
