Embodiment Construction

[0024] Figures 1A-1C Different configurations of an antenna array integrating an active array with a passive array are schematically shown according to various embodiments. In a passive array, coverage can be provided for user equipment within a sector supported by the passive array. Phase and / or amplitude offsets can be applied to individual transmissions from the passive array to form beams to form the coverage provided to all user equipment within the sector. In an active array, coverage can also be provided for user equipment within the sectors supported by the active array. However, being able to apply a phase and / or amplitude offset to each transmission from the passive array to form beams to form the coverage provided individually to each user equipment within the sector, this configuration significantly improves The Signal-to-Noise Ratio (SNR) and Signal-to-Interference Ratio of transmissions in the network are analyzed, which are particularly critical metrics in som...

Abstract

An antenna array and a method are disclosed. The antenna array comprises: a plurality of active antenna elements, each active antenna element being separated by a predetermined first spacing distance; and a plurality of passive antenna elements, each passive antenna element being separated by a predetermined second spacing distance. By providing both active and passive antenna elements, multiple networks can be supported by the same antenna array. Providing a dual network antenna significantly simplifies base station provision since existing base station sites may be reused more readily. Also, the number of antenna arrays which need to be provided at those base stations sites may be significantly reduced, thereby reducing mast head congestion and also reducing mast head loadings since the mass of the dual antenna array and its wind loading characteristics will be significantly less than that of two separate antenna arrays.

Description

technical field [0001] The present invention relates to antenna arrays and methods. Background technique [0002] Antenna arrays are known. For example in many mobile telecommunication systems a large number of base stations are arranged to communicate with a large number of user equipments using antenna arrays typically located on top of base station towers. Each base station is geographically separated from each other to provide communication coverage over a large area. Each base station is typically configured to support multiple "sectors" extending outward from the base station location. Each sector is typically supported by one antenna array, so an 'n' sector base station will be supported by 'n' antenna arrays. Each antenna array is mounted, oriented and configured to provide the desired geographic coverage to user equipment. [0003] Although such antenna arrays support wireless communication between user equipment and base stations, their deployment has a number ...
