Hi,
using the Antenna Toolbox I want to generate a PCB Antenna using PCBstack with a custom pattern top metal layer, a dielectric (FR4) in the middle and an infinite groundplane as bottom layer. You provide a similar example, using patchMicrostrip():
https://nl.mathworks.com/help/antenna/ug/model-infinite-ground-plane-for-unbalanced-antennas.html?searchHighlight=Model%20Infinite%20Ground%20Plane%20for%20unBalanced%20Antennas&s_tid=srchtitle_Model%2520Infinite%2520Ground%2520Plane%2520for%2520unBalanced%2520Antennas_1
How can i use an Infinite groundlayer in this case? I cannot make it work for a custom PCBstack-Antenna because it is not able to set one end of the feed onto the infinte ground (it does not accept it as a layer for the PCBstack).
Thank you very much

Hi apex,
As per my understanding, you want to set ground plane length to be infinite for a custom PCB Stack antenna. Currently PCB Stack doesn’t support ground plane length to be infinite. For a custom PCB Stack Antenna, the layers are antenna shapes whose dimensions must be finite that is the reason it doesn’t support infinite length.
