2nd method of Envolovpe corelation coefficient of 2x1 MIMO antenna at THz frequency bands
Envelope Correlation Coefficient:
Envelope correlation coefficients (ρ) are a measure of the correlation between the amplitudes of signals received or transmitted by different antenna elements in a MIMO system. Low envelope correlation coefficients indicate that the antennas are less correlated, which is generally desirable in MIMO systems to achieve diversity gain.
Low Value: A low envelope correlation coefficient implies that the MIMO antennas are relatively uncorrelated in terms of their signal amplitudes. This is desirable in MIMO systems, as it enhances the spatial diversity gain.
High Value: A high envelope correlation coefficient suggests that the MIMO antennas are strongly correlated in terms of their signal amplitudes. This can result in reduced spatial diversity gain and may limit the system's ability to combat fading and interference effectively.
