A communication system can comprise an ordered arrangement or array of two sets, groups, or groups of antenna elements. The system can transmit or receive two bands or ranges of electromagnetic energy, signals, or radiation. The first set of the antenna elements can operate one of the bands, while the second set can operate the other band. The first set of antenna elements can be arranged or disposed to form a line or a column. The second set of antenna elements can be arranged or disposed on opposite sides of the line, with some of those elements on one side of the line and the remainder on the other side. The antenna elements that are on one side of the line can be staggered or longitudinally offset with respect to the antenna elements that are on the opposite side of the line.
