An aircraft has a fuselage and a pair of wings joined to the fuselage at a dihedral angle. A wing extension, such as an angled winglet or a wing-tip pod, is joined to a distal end of each of the wings. A top-surface antenna lies in each of the top surfaces, and a bottom-surface antenna lies in each of the bottom surfaces. The antennas are preferably flat-panel antennas such as phased-array antennas.
