An antenna (2) for a radio frequency communications device comprises a substrate (20), and a plurality of discrete antenna elements (21) located on the substrate (20). The antenna elements (21) are arranged on the substrate (20) in a plurality of groups (a, b, c, d, e, f), the groups (a, b, c, d, e, f) being spaced apart from one another across the substrate (20) in a first direction (x), and each group (a, b, c, d, e, f) having one or more antenna elements (21) therein. The antenna elements (21) for each group (b, c, d, e) having a plurality of elements (21) therein are arranged in a second direction (y) substantially perpendicular to the first direction (x), and at least two of the groups (a, b, c, d, e, f) have different respective numbers of antenna elements (21) therein. |
