摘要:
A multi-antenna system feed device and a terminal including such a device is suggested.The device includes at least: a set of Wilkinson combiners, a branch of a combiner feeding an antenna, with the branches connected as inputs to a feed point; a set of switches 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 feeding an antenna, for instance, will be common to two consecutive combiners of the system. The suggested multi-antenna system feed device 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.
