Abstract
A patch antenna is disclosed. The disclosed patch antenna may include: a first radiator configured to generate a circular polarized wave; a first dielectric substrate equipped under the first radiator; a second radiator, placed under the first radiator at a designated distance from the first radiator, and configured to generate a linear polarized wave; a second dielectric substrate equipped under the second radiator; and a reflecting plate equipped under the second radiator at a designated distance from the second radiator; where the first dielectric substrate, the second radiator, the second dielectric substrate, and the reflecting plate are connected through at least one via. A patch antenna according to the present invention has the advantages of being able to generate linear polarized waves and circular polarized waves simultaneously, and of having a small size while still having a high design frequency band.
