Stitching vias are more than just periodic via arrays, they provide groups of net connections across layers that are needed in power, RF, high-speed, and more.
The simple answer is “no,” all antennas will have a ground plane somewhere, even if it is not on the PCB.
Essential tips for high-speed PCB designs, and when you need to start being concerned about how and where you route your traces.
How to assign layer types in a PCB? Expert Phil Salmony shares with us some of his favorite multilayer stackups, complete with guidelines.
Microstrip patch antennas are simple structures to design and fabricate, and they are very useful up to very high frequencies.
A patch antenna is simple to design in a PCB. These components are placed above a ground plane and require impedance matching.
PCB designers don’t just build boards and assemblies. Today, they are mainstays in the electronics product design process.
