Possible Prior Art

One possible prior art is the use of stacked patch antennas in communication systems to improve antenna performance and efficiency.

Unanswered Questions

1. How does the capacitive coupling between patch antenna elements affect the overall antenna performance? 2. Are there any limitations or drawbacks to using a stacked patch antenna device in certain applications?


Original Abstract Submitted

A stacked patch antenna device is provided which comprises: a ground layer and a stack of patch antenna elements being mounted over each other and over the ground layer. Each patch antenna element comprises: a metal sheet having a plurality of peripheral areas; at least one feeding pin configured to connect the patch antenna element to a feeding circuit for inductively feeding the patch antenna element. Each patch antenna element comprises 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. 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.
