. FR-4 laminates tend to have the highest dielectric loss and least flat Dk vs. frequency response, making them suitable for low GHz applications such as mobile phones, computers, telecommunications, and internet infrastructure

. Rogers materials perform best in these environments, as they have low dielectric loss and an expansive frequency range. A full list of materials, along with their dielectric constants and frequency ranges can be found here

‐loss, stable operation from the relatively low frequencies through the higher frequencies in the microwave regions. These transmission‐line cables should not be confused with low‐frequency cables with conductive sheaths (usually
