    • This invention relates a multi-antenna system feed device and a terminal including such a device. The device includes at least: - a set of Wilkinson combiners (45, 46, 47, 48), a branch (401, 402, 403, 404) of a combiner feeding an antenna (41, 42, 43, 44), with the branches connected as inputs to a feed point; - a set of switches (51, 52, 53, 54) connected between the antennas and the combiners with each switch switching a combiner branch to its corresponding antenna with the antenna being connected to the line when the switch is closed; A branch (401, 403) feeding an antenna, for instance, will be common to two consecutive combiners (46, 47) of the system. The invention applies in particular to the extension of multi-antenna or sector antenna systems, used especially in devices with Multiple Inputs/Outputs of the MiMo type and more specifically to mesh network architectures.
    • 本发明涉及多天线系统馈电装置和包括这种装置的终端。 该设备至少包括:一组威尔金森组合器(45,46,47,48),馈送天线(41,42,43,44)的组合器的分支(401,402,403,404),其具有 分支作为输入连接到馈电点; - 连接在天线和组合器之间的一组开关(51,52,53,54),其中当开关闭合时,每个开关将组合器分支切换到其相应的天线,天线连接到线路; 例如,馈送天线的分支(401,403)对于系统的两个连续的组合器(46,47)将是共同的。 本发明特别适用于多天线或扇区天线系统的扩展,特别是在具有MiMo类型的多输入/输出的设备中,更具体地涉及网状网络架构。
