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.

Dependent claims

An antenna for communicating in a first Frequency Division Duplex (FDD) band and a second FDD band, comprising:

a first combiner splitting an input channel thereof into a first output channel and a second output channel;
a second combiner having an input channel thereof connected to the first output channel and splitting the first output channel into two output channels;
and
a third combiner having an input channel thereof connected to the second output channel and splitting the second output channel into two output channels,
wherein the second and third combiners are configured to separate the first and second FDD bands in an inverted transmitter/receiver fashion, and
one of the output channels of the second combiner is configured to carry a transmission band of the first FDD band, another of the output channels of the second combiner is configured to carry a reception band of the second FDD band, one of the output channels of the third combiner is configured to carry a transmission band of the second FDD band, and another of the output channels of the third combiner is configured to carry a reception band of the first FDD band.
