AI Technical Summary

Problems solved by technology

Digital beamforming is the most flexible solution, but also the most expensive due to the large number of radios and baseband chains required
Analog beamforming is the least flexible due to the reduced number of radios and baseband chains, but is less expensive to manufacture

Embodiment Construction

[0030] In the following description, for purposes of illustration and not limitation, specific details are set forth, such as specific architectures, interfaces, techniques, etc., in order to provide a thorough understanding. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description with unnecessary detail. Throughout this specification, the same reference numerals refer to the same or similar elements.

[0031] Briefly, according to various embodiments of the present teachings, an antenna panel with a reconfigurable distributed feed network is provided such that single polarization beamforming (SPBF) or dual polarization beamforming (DPBF) can be applied.

[0032] figure 1 Antenna arrays (also referred to as antenna panels) are shown, and in particular two examples of dual polarized analog antenna arrays are shown. A two-dimensional (planar) antenna array 10 is shown on the left and a one-dimensio...

Abstract

An antenna arrangement (1) comprising a dual polarized antenna array (10) and a reconfigurable feed network (17) connected thereto is provided. The dual polarized antenna array (10) comprises a numberof radiating antenna elements and the reconfigurable feed network (17) comprises switching means (20) for switching the feed network (17) between: a first mode providing single polarization beamforming, SPBF, in which first mode the feed network (17) is arranged such as to connect all antenna elements having a first polarization P1 to a first port, A, and all antenna elements having a second polarization P2 to a second port, B, and a second mode providing dual-polarization beamforming, DPBF, in which second mode the feed network (17) connects a part of all antenna elements having a first polarization P1 and a part of all antenna elements having a second polarization to the first port, A, and a remaining part of all antenna elements having the first polarization P1 and the remaining part of all antenna elements having the second polarization P2 to the second port, B. A method (30), computer program (42) and computer program product (41) are also provided.

Description

technical field [0001] The technology disclosed herein relates generally to the field of antenna technology, and in particular to antenna arrangements, methods, computer programs and computer program products including a dual-polarized antenna array and a reconfigurable feed network connected thereto. Background technique [0002] There are various requirements for the next generation mobile communication system (5G). This implies that many bands of different carrier frequencies will be required. For example, low frequency bands will be required to achieve adequate coverage, and higher frequency bands (eg, millimeter wave (mmW), ie around and above 30 GHz) will be required to achieve the required capacity. At high frequencies, the propagation characteristics are more challenging and may require beamforming at both the transmit / receive point (TRP, e.g., access point (e.g., base station)) and the communication device (e.g., user equipment (UE)) shaped to achieve an adequate ...
