Title:
MULTI-INPUT MULTI-OUTPUT (MIMO) ANTENNA AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/111409
Kind Code:
A1
Abstract:
Disclosed are a multi-input multi-output (MIMO) antenna and a communication device. The MIMO antenna comprises at least x antenna units, x being an integer greater than or equal to 2. A first antenna unit is electrically connected to a first grounding point and a first feeding point respectively; the first grounding point does not coincide with the first feeding point; the first antenna unit is any antenna unit in the at least x antenna units; and the first grounding point is electrically connected to a grounding point corresponding to another antenna unit by means of a first feeding line. Insofar as a matching circuit is cancelled, it is effectively ensured that a working frequency band of the antenna is matched with an isolation degree, and the space occupied by the antenna is reduced.
