Abstract: An integrated antenna element includes a top PCB and a bottom PCB arranged in a laminate structure. Radiating surface units are arranged between the top PCB and the bottom PCB. A first balun and a second balun set separately set on the top and bottom PCBs respectively, each for different polarization. The integrated antenna element is capable of transmitting signals to a base station and receiving signals from a base station.

Abstract: An integrated antenna unit includes an integrated radiating element; a reflect board beneath the integrated radiating element without a direct contact therebetween; and an RF component device for processing signal of interest for a radio unit. The RF component device is placed beneath the integrated radiating element and on the reflecting board, and serves a support of a fixture structure of the radiating element to the reflecting board; whereby a space between the radiating element and the reflecting board can be efficiently used for the RF component device.

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: An integrated antenna unit where two dual-polarized radiating elements are connected on a PCB serving reflecting board as well as a filter lid of two-band pass filters. Each of two band-pass filter is connected directly to a two-way power splitter serving connection of same polarization from the two radiating elements. Two walls running parallel are extending at the band-pass filter edges to support the cavity of the filters and at same time serving as reflecting walls enabling to control the 3 dB azimuth beam generated by the radiating elements. Next, a multi-array antenna by collocating multiple arrays of the integrated antenna units.

Abstract: An integrated antenna element includes a compact printed board and at least two dual-polarized radiating elements. The compact printed board includes a top PCB and a bottom PCB in a laminate structure. Each radiating element includes a radiating surface unit and a layered-balun.
