A basic question about using dielectric material in PCB boards in relation to electric field
I was wondering what the PCB's dielectric material(such as FR-4) do to the electric field.
If I'm not wrong, the dielectric material influences how the electric field lines are distributed. And it ...

Effective dielectric constant in multilayer PCB design
Top => copper
PP1 => RO4350B
L2 => copper
PP2 => FR4
L3 => copper
PP3 => 185HR
L4 => copper
This is my PCB stackup.
In the top layer, I have a 50 Ω controlled RF trace. The ...

How to determine dielectric constant and loss tanget of a PCB board at a specific frequency?
I need to know dielectric constant (relative permittivity) and Tan loss of a FR4 board at 2.45 GHz.
The specification of the manufacturer is as it is below:
Dielectric Constant:
Test method (IPC-TM-...
