Antenna system providing coverage for multiple-input multiple-output, MIMO, communication, a method and system

Abstract:

The disclosure relates to an antenna system 1 for providing coverage for multiple-input multiple-output, MIMO, communication in mixed type of spaces. The antenna system 1 comprises a leaky cable 2 arranged to provide coverage in a first type of space, and a distributed antenna system 3 comprising one or more antennas 3.sub.1, 3.sub.2, 3.sub.3, 3.sub.4 and ranged to provide coverage in a second type of space, wherein each of the one or more antennas 3.sub.1, 3.sub.2, 3.sub.3, 3.sub.4 of the distributed antenna system 3 is connected to the leaky cable 2 through a circulator 4.sub.1, 4.sub.2, 4.sub.3, and wherein the MIMO communication is enabled by both ends of the leaky cable 2 being adapted for connection to a respective antenna port 8, 9 of a network node 5 configured for 10 MIMO communication. The disclosure also relates to a related method and system.
