Document Type and Number:
WIPO Patent Application WO/2021/085483
Kind Code:
A1
Abstract:
Provided is a compact MIMO antenna device capable of suppressing interference between antennas in wide bands. A MIMO antenna device for performing spatial multiplex transmission comprises a first dipole antenna 10 and a second dipole antenna 20. The first dipole antenna 10 comprises a pair of first elements 11 connected to a first feed unit 13 and disposed on a first surface 12. The second dipole antenna 20 comprises a pair of second elements 21 connected to a second feed unit 23 and disposed on a second surface 22 opposing the first surface 12. The second dipole antenna 20 is disposed across the first dipole antenna 10 in a top view, with the second feed unit 23 generally overlapping the first feed unit 13 and without major parts of the pair of second elements 21 overlapping major parts of the pair of first elements 11.
