Traditional FR4 exhibits significant dielectric loss at frequencies above 24GHz, while PTFE, although reducing signal delay, suffers from processing deformation issues. In practice, modified PTFE laminates with glass fiber or ceramic fillers offer a balance of low loss and stability. However, not all high-frequency scenarios require PTFE&#x2014;for example, in automotive applications...</description></oembed>
