The standard of 802.11n offers the connection in MIMO technology. There is a possibility to use 1-4 polarizations in that standard. These days the most popular are 2x2 connections using Horizontal and Vertical polarizations. For more than 2 antennas to separate radio streams there are needed more polarization options. We achieve them by the rotation of antennas achieving X polarity, so simply speaking means +45 and -45 deg polarity (with relation to V or H polarity).

At the beginning it’s important to determine the definition of X-polarity. In our case X-polarity is slant +/- 45 deg polarization, so simply speaking means MIMO antenna rotated of 45 deg. This technique is used for example in 3x3 and 4x4 antennas in 802.11n standard or in more complex standards as 802.11ac.
