Abstract :
Measured results for pattern correlation in antenna arrays are compared to idealised values. It is shown that pattern correlation at small element separations is lower than the ideal values (a beneficial effect of mutual coupling). Observations are made regarding the various decorrelating effects in the array, including spacing, ground plane size and mutual coupling.
