1. An apparatus for use with a portable, hand-held telephone (T) for communicating directly with a satellite in Earth orbit comprising:

  • an antenna body (10A) consisting essentially ofa generally truncated cone, also for transmitting radio beams to said satellite in Earth orbit;

    said generally truncated cone, for receiving radio beams from said satellite in Earth orbit;

    said generally truncated antenna (10A) cone havinga first antenna surface (12); and

    a second antenna surface (14);

    a plurality of phased array antenna elements (18);

    said plurality of phased array antenna elements being located on said first and second antenna surfaces (12 and

         14);

    a first plurality of beam steering components for steering said radio beams in an azimuth dimension;

    said first plurality of beam steering components being coupled to said plurality of phased array antenna elements (18) located on said first antenna surface (12); and

    a second plurality of beam steering components for steering said radio beams in an elevation dimension;

    said second plurality of beam steering components being coupled to said plurality of phased array antenna elements (18) located on said second antenna surface (14).
