The study found that the dielectric constant variations due to glass fiber weaves in PCBs significantly impact the performance of millimeter-wave radar antennas, with antennas using RO4830 laminates showing superior performance compared to those with RO4835 laminates.
Millimeter wave radar performance is influenced by the design and structure of Read More »
FR4 PCBs experience significant changes in dielectric constant and signal delay due to temperature and frequency variations, impacting filtering performance, which can be managed by using capacitors with appropriate ESR values to address resonance issues.
