1. A patch antenna synchronously generating a linearly polarized wave and a circularly polarized wave, comprising:

  • a first radiator radiating a circularly polarized wave with respect to an antenna signal;

    a first substrate provided at a part or the whole of the rear surface of the first radiator;

    a second radiator provided at a part or the whole of the rear surface of the first substrate and radiating a linearly polarized wave with respect to the antenna signal;

    a second substrate provided at a part or the whole of the rear surface of the second radiator; and

    an auxillary radiator which is provided on a front surface of the first substrate is spaced apart from the first radiator by a predetermined distance.
