1. , a kind of device that uses in transmitting set comprises:

  • First antenna (12);

    Second antenna (18);

    AndPower amplifier (34), have and be used to receive input and the output signal that transmits, described output signal offers described first antenna and described second antenna so that send described output signal diversity to radio receiver, and described device is characterised in that;

    Phase shifter (38) is used for before by described second antenna transmission phase deviation first of described output signal being measured, and makes to have relative phase shift in the output signal that transmits from described first antenna and between the output signal of described second antenna transmission.
