A dimensionless quantity that replaces the term directive gain in the IEEE definitions for antennas.

"Directivity is the ratio of the radiation intensity in a given direction from the antenna to the radiation intensity averaged over all directions. The average radiation intensity is equal to the total power radiated by the antenna divided by (4 * π). If direction is not specified, the direction of maximum radiation intensity is implied."
-Definition from the 1983 version of the IEEE Standard Definitions of Terms for Antennas
