PCB Design

Warum hat meine HF-Leiterplatte kleine Löcher im Erdungspolygon??

The space between copper planes can act as waveguides for RF frequencies. It makes trace impedance changes and signal losses.

To cut such waveguide effect, put vias, which is essentially a copper cylinder.

When the distances between vias are small enough compared to the wavelength, the board is like continuous copper material, instead of waveguide.
