Millimeter-wave communications on a multifunction platform

A method of millimeter-wave (MMW) communications, comprising:

• generating a first data modulated MMW signal from a first baseband signal generator and a first MMW source operating at a first MMW frequency;
• generating a second data modulated MMW signal from a second baseband signal generator and a second MMW source operating at a second MMW frequency;
• coupling, via a first switch, the first data modulated MMW signal to a first antenna coupling point of an antenna array structure operating within a MMW band;
• coupling, via a second switch, the second data modulated MMW signal to a second antenna coupling point of the antenna array structure;
• generating, responsive to actuating the first switch, a first MMW radio signal corresponding to the first data modulated MMW signal, the first MMW radio signal transmitted at a first propagation direction by the antenna array structure at the first MMW frequency;
• and
• generating, responsive to actuating the second switch, a second MMW radio signal corresponding to the second data modulated MMW signal, the second MMW radio signal transmitted at a second propagation direction by the antenna array structure at the second MMW frequency, wherein the first propagation direction and the second propagation direction are located within a plane that is perpendicular to the coplanar surface.
