text: In an antenna array (a set of multiple identical antennas which work together as a single antenna), the directivity of the entire array is the multiplicative sum[clarification needed] of the individual antenna's directivity function with a mathematical expression known as the array factor A F {\displaystyle AF} , which typically depends on the location, the excitation and the phase of each antenna element.
