- the main axes of the radiation beam of particular antenna modules H1 and H2 are arranged at an angle of 33.4°, starting from the edge of the 120° angular sector. This means that antenna modules H1 and H2 are used in directions of ⁇ 26.6°, which enables a wide range of changes in beams in plane H of 53.2°.
- the adaptive antenna comprises three modules H1, H2 and H3, arranged edgeways next to each other.

- the adaptive antenna comprises four modules H1, H2, H3 and H4 arranged edgeways next to each other.
- the resulting axes of the antenna azimuths divide the 120° angular sector into four equal sectors of 30° each.
- Each of modules H1 and H2 of the adaptive antenna with two modules has eight radiators 1 arranged along the vertical axis of each antenna module H1 and H2 and at the same time symmetrically with respect to the horizontal axis of antenna modules H1 and H2.
- First two radiators 1, viewed from the top of antenna modules H1 and H2, are spaced from each other by 9 cm, and from another, second pair of radiators 1 by 10.9 cm.
- the second pair of radiators 1 is constituted by two radiators 1 spaced from each other also by 9 cm.
- the next two pairs of radiators 1 are arranged on antenna module H1 symmetrically to the first two pairs of radiators 1 with respect to the horizontal axis of antenna module H1.
- the radiators 1 closest to the horizontal axis are spaced from it by 3.6 cm, i.e. the distance between them is 7.2 cm.

- each of antenna modules H1 and H2 has two columns, 8 radiators 1 each, arranged symmetrically on both sides of the vertical axis of antenna modules H1 and H2.
- radiators 1 are powered directly by the power supply systems. With a larger number of bays (tiers), the radiators 1 (dipoles) can be combined in pairs powered jointly by a coaxial power divider 2 1:2 with wave impedances of input and outputs, matched to wave impedances of wires connected to input and outputs of the power divider 2.
- power dividers 2 1:3 or 1:4 are used.
- the power divider can be realised on coaxial cables having wave impedances matched by a matching network. Wave impedance at the antenna inputs is 50 W, obtained if necessary by an impedance transformer realised via a coaxial cable section having its wave impedance and length matched.

- antenna modules H1 and H2 can be powered by radiators of linear polarisation.
- each radiator 1 comprises two orthogonally polarised dipoles, preferably with a polarisation of ⁇ 45°.
- Method of controlling an adaptive antenna beam with orthogonally ( ⁇ 45°) polarised radiators 1 consists in that, by means of BBU (base band unit) decision unit, for each of 4 paths of antenna modules H1 and H2, i.e. for internal and external sectors of module H1 and for internal and external sectors of antenna module H2, CSI-RS (cell specific indicator reference signal, compliant with the standard Rel 10) indicators are assigned. Then, CSI-RS indicators are transmitted in DL (downlink) channel to the user equipment UE, every 10 frames in slot number 2. In the user equipment, based on the received indicators, CQI (cell quality indicator) value is determined, and this indicator is transmitted in UL (uplink) channel to NodeB, i.e.
- BBU base band unit
- RRH radio remote head
- BBU radio remote head
- the indicator included in the transmitted signal is received by all elements of the antenna. Due to the polarisation used, 8 paths (4 paths and each in two polarisations of ⁇ 45°) arrive from the UE to the antenna. Then, orthogonally polarised signal, received in the beam, is summed in the power divider 1 1:2, and by means of 4 CPRI (common public radio interface) interfaces, performed on optical fibres, 2 interfaces for one antenna module, it is transmitted to BBU, where it is demodulated. In the next step, BBU, based on CQI received in the signal, selects an optimal transmission path which matches the highest CQI, wherein CQI is in the range of 1 to 15.
- CPRI common public radio interface
- Modulated LTE signal comprising data of PDSCH (physical downlink shared channel), PDSCH1 for the internal sector of the cell and PDSCH2 for the external sector of the cell, respectively, is multiplied by controlling vectors [K1, K2, K3, K4] and [L1, L2, L3, L4].
- Vectors [K] and [L] are responsible for the tilt of internal and external beams for each antenna module H1 and H2.
- the tilt of the beam of 5° is realised by progressive shift of power supply phase with a progression of 17°, i.e. the first bay- 0°, the second bay+17°, the third bay+34°, etc. Whereas, the tilt of the antenna beam by 10° represents a progression of 34°.
- Controlling vectors [K] and [L] are determined in the optimisation process. Their value is predefined beyond the standardised process of LTE signal processing. Vector values are selected based on drive-tests, i.e. on radio measurements, and are made dependent on the surrounding environment. The determined predefined values, which are subject to the optimisation process and are corrected by crews that integrate the network, are assigned.
- a phase shifted signal is obtained, which is then processed from digital to analogue form in the D/A converter and is transferred to the amplifier 3, where the signal is amplified and transmitted to the power divider 2 1:2 and to the radiators 1 of one polarisation.
- the radiators 1 comprise two orthogonally polarised dipoles with polarisations of ⁇ 45°, thereby, each of the dipoles is individually powered by a system of powers divider 2 1:2, a D/A converter, an antenna matching network and an amplifier.
- power dividers 1 1:3 or 1:4 are used, then radiators of one polarisation from one antenna module are grouped.
- controlling vectors [K] and [L] are controlled by means of SON (self-optimising network). Then, the selection of angle of sector tilts is realised dynamically.
- SON functionality of which is realised by BBU, actually uses features of the antenna as a fully adaptive antenna. Algorithms for determining vector values [K] and [L] constitute an integral part of the processes controlled by SON. BBU without SON takes a decision related to the allocation of PDSCH channel to the right path but does not modify it. In an example using SON, through the control of vectors [K] and [L], available paths can be dynamically modified.
- the final, additional tilt of the beam is realised by a RET (remote electrical tilt) module in which the signal before being passed to the power divider 1 is multiplied by a constant value.
- RET remote electrical tilt
- an alternative path of vertical sectoring is possible in the method according to the invention as the remaining vector [K] and [L] is used for multiplying the signal and for forming an alternative receiving channel analogously to the main path.
- the signal received by the module is subjected to the same processing as for the main module H1.
- two other alternative paths are provided for UL channel having two orthogonal polarisations.
- the beam control relates to an antenna comprising two modules H1 and H2
- a joint transmission of PDSCH 1 and PDSCH2 on antenna module H1 is possible, in the absence of transmission on antenna module H2.
- module H1 does not transmit the signal, but antenna module H2 transmits PDSCH1 together with PDSCH2.
- antenna module H1 transmits PDSCH1
- antenna module H2 transmits PDSCH2.
- antenna module H1 transmits PDSCH2, and module H2 transmits PDSCH1.
- module H1 is the leading module.
- horizontal radiation pattern of each module are in the range of 65° ⁇ 5° for HPBW -3dB.
- the leading module H1 is selected for the transmission of control channels.
- Module H1 is the leading module, operates on the basis of conventional principles of passive antenna, and in particular transmits information of logical control channels.
- logical channels for PDSCH logical channels, module H1 or H2 and dedicated tilt of the beam are selected.
- Data channels, including PDSCH are transmitted according to the method of the invention.
- possible transmission configurations include a joint transmission on modules H1, H2 and H3, transmission on modules H1 and H3, and transmission on module H2, if radiation patterns of the modules are diversified and if module 2 meets the criteria of 65° ⁇ 5° for HPBW -3dB.
- Method of controlling the beam can be also used in adaptive antennas comprising more than two antenna modules. Then, for the method using an antenna with 4 modules, possible configurations include a joint transmission on modules H1, H2, H3 and H4, transmission on modules H1, H3, transmission on modules H2 and H4, and transmission on modules H2 and H3. For data channels, a cyclic switching of beams according to the method of the invention is used.
