1. A stacked patch antenna device, comprising:
a ground layer; and
a stack of patch antenna elements being mounted over each other and over the ground layer, each patch antenna element of the stack comprising:
a metal sheet having a plurality of peripheral areas;
at least one feeding pin configured to connect a patch antenna element to a feeding circuit for inductively feeding the patch antenna element; and
a plurality of capacitive pads for capacitively coupling the patch antenna element with another patch antenna element underneath the patch antenna element or with the ground layer, wherein each capacitive pad is mounted below a respective peripheral area of the metal sheet and attached to the respective peripheral area of the metal sheet by a metal connector.
