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.
