Abstract
A patch antenna synchronously generating a circularly polarized wave and a linearly polarized wave comprises 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, and a second substrate provided at a part or the whole of the rear surface of the second radiator.

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.
A method for synchronously generating a linearly polarized wave and a circularly polarized wave by a patch antenna, comprising:
- radiating a circularly polarized wave with respect to an antenna signal by a first radiator provided at a part or the whole of the front surface of a first substrate;
- radiating a linearly polarized wave with respect to the antenna signal by a second radiator provided at a part or the whole of the front surface of a second substrate;
- generating a linearly polarized wave by an auxiliary radiator provided at a part or the whole of the front surface of the first substrate.
