Multi-layer patch antenna device and vehicle

A multi-layer patch antenna device, comprising:

• a lower antenna layer,
• a middle antenna layer, and
• an upper antenna layer,
• wherein the antenna layers are arranged in a predetermined installation position in a manner stacked on top of each other from bottom to top,
• the respective antenna layers comprise a respective dielectric substrate layer,
• wherein an underside of the respective dielectric substrate layer is coated with a lower metal layer, and a top side of the respective dielectric substrate layer is coated with an upper metal layer,
• the upper metal layer of the middle antenna layer is contacted by two feed pins which are guided through the lower and middle antenna layers,
• the metal layers of the lower antenna layer are connected to each other via a first hollow pin which is guided through the lower dielectric substrate layer,
• the metal layers of the middle antenna layer are connected via a second hollow pin which is guided through the middle dielectric substrate layer,
• the metal layers of the upper antenna layer are connected via shorting pins which are guided through the dielectric substrate layer of the upper antenna layer, and
• the upper metal layer of the upper antenna layer is contacted by a further feed pin which is guided through the antenna layers and is coaxially sheathed by the first hollow pin and the second hollow pin.
