MULTI-ANTENNA SYSTEM FEED DEVICE AND WIRELESS LINK TERMINAL EQUIPPED WITH SUCH A DEVICE.

摘要

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.
