Via fence
Figure 2. Diagram of a microstrip via fence A via fence consists of a row of via holes, that is, holes that pass through the substrate and are metallised on the inside to connect to pads on the top and bottom of the substrate. In a stripline format both the top and bottom of the dielectric sheet are covered with a metal ground plane so any via holes are automatically grounded at both ends. In ...
Such details provide a deeper understanding and appreciation for Microstrip Ground Plane With Via.
The most common transition is the differential via where the signal pair must transition from an upper stripline layer or top microstrip to a lower stripline layer or bottom microstrip . The following figure shows a Ground -Signal-Signal- Ground (GSSG) type differential via . Ground vias are connected to each ground plane ...
A clean microstrip -to-stripline via transition requires: (1) a signal via with diameter matching the trace width, (2) adjacent ground vias within λ/20 of the signal via forming a coaxial-like structure, (3) anti-pad (clearance hole) in non-connected ground planes sized for 50 Ω impedance, and (4) back-drill or blind via to eliminate the stub below the stripline layer. Without ground vias ...
As we can see from the illustration, Microstrip Ground Plane With Via has many fascinating aspects to explore.
