A communication device for a vehicle in which an RF device in the room mirror is connected electrically to a radiator included in a shade band is disclosed. The communication device for a vehicle includes an RF device in a room mirror and a radiator disposed in a shade band and connected electrically to the RF device.

Communication device for a vehicle, room mirror structure included in the same and shade band connected electrically to the room mirror structure

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.

Patch antenna

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.

Patch antenna synchronously generating linearly polarized wave and circularly polarized wave and generating method thereof

The present invention relates to a technology for forming a patch antenna generating both linearly and circularly polarized waves at the same time, so as to reduce a propagation loss during transmission/receiving operations between a circularly polarized antenna and a linearly polarized antenna.
