Abstract
An antenna module is an array antenna in which an array of antenna elements extends in at least a first direction. The array of antenna elements in the first direction includes a first antenna group in a middle portion and a second antenna group in two end portions adjacent to the middle portion. The antenna elements in the first antenna group are unequally spaced. The spacing between adjacent antenna elements in the second antenna group is greater than the maximum spacing between adjacent elements in the first antenna group. The amplitude distribution in the antenna module as a whole in the first direction is in a unimodal form in which the amplitude of a radio-frequency signal fed to the antenna elements in the second antenna group is smaller than the amplitude of a radio-frequency signal fed to the antenna elements in the first antenna group.
