3 Layer Hybrid PCB Board Made On 13.3mil RO4350B and 31mil RT/Duroid 5880 for Multicoupler Antenna
(PCB's are custom-made products, the picture and parameters shown are just for reference)
The hybrid PCB can be a mixture of FR-4 and high frequency material, and a mixture of high frequency material with different dielectric constant (DK), for example RT/duroid 5880 and RO4350B etc.
Today we’ll talk about a type of mixed high frequency PCB made on 13.3mil (0.338mm) RO4350B and 31mil (0.787mm) RT/duroid 5880. It’s for the application of multi-coupler antenna.
