This article confuses directivity and directive gain. The function of direction is usually called the directive gain, and the peak directive gain (or the directive gain in the direction of interest) is called the directivity (see for example Orfanidis [1] and the IEEE dictionary [1]).

OK - I stand (semi-) corrected; later editions of the IEEE dictionary (including the 6th ed. [1]) say that the term directive gain is now deprecated and that directivity should be used both for a given direction and for the maximum (If the direction is not specified, the direction of maximum radiation intensity is implied). However, I'd say that it's still common practice to distinguish the two terms (as in Orfanidis [2]). -- catslash 10:06, 4 September 2007 (UTC)
Here're some things that the article could mention:
-- catslash 18:04, 31 August 2007 (UTC) Note regarding the gain: the IEEE Dictionary [1] calls this quantity the realized gain; so
where is the antenna efficiency, the radiation efficiency and is the power 'accepted' by or 'delivered' to the antenna from the feed. -- catslash 16:05, 17 September 2007 (UTC)
