Abstract

The invention discloses a two-dimensional MIMO antenna array, which forms an equivalent virtual receiving antenna array by reasonably arranging transmitting antennas and receiving antennas. By means of multi-input multi-output antenna array characteristics, multiple transmitting antennas and multiple receiving antennas are equated with an equivalent virtual antenna array having a single transmitting antenna and multiple receiving antennas through reasonable layout. Therefore, the number of actual antennas is decreased, and the problem is fundamentally solved that the antenna array has a largesize, a large number of antennas, and a complicated receiving system.

Description

technical field [0001] The present invention relates to the field of radio frequency technologies such as electromagnetic wave signal transmission and reception, and in particular to a two-dimensional multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO for short) antenna array. Background technique [0002] The antenna is an essential component of the wireless communication system and the radar system. The antenna plays the role of "head" or "tail" in the signal transmission process. When the electromagnetic wave is received from the air or medium to the circuit, the antenna is the first component of the receiving circuit; when the electromagnetic wave is transmitted to the air or medium, the antenna is the last component of the transmitting circuit. In practical applications, since the performance of a single antenna sometimes cannot meet the system requirements well, using multiple antennas in parallel, in series or forming a specific array can greatly imp...
