MIMO Antenna 9dBi Typ. Gain, 2.2-2.5GHz Frequency Range RM-MPA2225-9

A MIMO antenna, which stands for “Multiple-Input Multiple-Output” antenna, does not refer to a single antenna form, but rather an advanced antenna system technology. Its core concept involves using multiple transmitting antennas and multiple receiving antennas simultaneously within a single wireless communication system.

Its operating principle leverages the spatial dimension: multiple independent data streams are transmitted and received concurrently via the multiple antennas, utilizing the multipath effects created as radio waves propagate in the environment. These data streams are then separated and combined at the receiver using sophisticated algorithms, dramatically improving system performance.

The primary advantages of this technology are its ability to significantly increase channel capacity, data throughput, and link reliability without requiring additional bandwidth or transmit power. It is a foundational technology for modern high-speed wireless communication standards and is extensively used in 4G LTE, 5G NR, Wi-Fi 6 and beyond for both WLAN and mobile communication systems.
