AB  - Straight-line arrays produce highly directional polar response curves in the vertical plane resulting in high on-axis gain. In many venues, however, it is useful to blend this high on-axis gain with improved response in the near field beneath and in front of the array. To accomplish this the lower section of a straight-line array is curved. This paper derives the directivity functions of two such arrays, namely the "J-Array" and the "Spiral Array."
