Abstract: An antenna-unit (110) for at least dual-FDD bands includes a first combiner (100) splitting its input (101) into at least two outputs (102, 103). Each output (102, 103) operates in at least two narrow-bands from two different FDD systems, and is respectively connected to a second and third combiners (200, 300). The second and third combiners (200, 300) are respectively connected with a first RF circuit (800, 900) enabling separation of two different FDD channels in an inverted Transmitter/Receiver fashion. An antenna system (700) based on the antenna unit (110) includes a set of columns of dual-polarized radiating elements (500) arranged on a reflector (702), and the first RF circuit (800,900) is connected with a second RF circuit (10) of the Base Station processing, SDR is set along with the RF circuit (10) to enable 3D beamforming features as well as independent system link control for optimization purpose.

Abstract: A communication antenna and radiation unit thereof with tapered clearance slots for transceiving radiation signals disposed at four corners of the radiation unit. The slots form groups and are arranged and fed by two feeding units. A middle portion of the radiation unit is a flat central platform. Peripheries of the radiation unit are turned up to form folded edges. The communication antenna includes a reflecting plate and a radiation unit operating at a low frequency. The central platform has a high-frequency radiation element. The radiation unit has a small aperture and is lightweight, so the antenna size is reduced, and a radiation performance indicator can be ensured. The radiation unit is applied to a multi-frequency antenna, has little effect on a high-frequency oscillator, and is especially suitable for a multi-frequency base station antenna with a low-frequency unit and a high-frequency unit forming an array in a nested manner.

Abstract: An omnidirectional array antenna includes N omnidirectional subarray units circumferentially arranged to form a circular array, where each of the omnidirectional subarray units includes p coaxially-arrayed symmetrical oscillators, and N and p are both natural numbers. The omnidirectional array antenna beamforming method includes various omnidirectional subarray units stimulated by equiamplitude, in-phase or out-phase stimulation, thereby forming different types of transaction beams, such as an omnidirectional beam, a double-beam, a triple-beam, and a quadruple-beam.
