In this paper, a four-port antenna with symmetric structure is presented on a circular patch to be able to produce four orthogonal patterns with extremely low correlation coefficients (less than 0.001) and high gain in the frequency range of 4.4–5.2 GHz and SWR 1.22, which is highly efficient in creating independent and simultaneous communication paths in MIMO systems. To create this orthogonality and decrease the correlation between channels, the characteristic modes method is used. Circular polarization can be obtained by changing feeding structure in this antenna.
