What material is used in Radar/Antenna substrate?

Material selection for radar and antenna substrates is critical to system performance and reliability. Common radar/antenna substrate materials include polytetrafluoroethylene (PTFE), glass fiber reinforced epoxy resin (FR-4), and PTFE glass fiber, etc.

Polytetrafluoroethylene (PTFE) is an excellent radar/antenna substrate material with excellent high temperature resistance, chemical resistance and dielectric properties. Due to its low dielectric constant and dielectric loss, PTFE is widely used in high frequency and microwave applications and can provide excellent signal transmission performance. However, the cost of PTFE is relatively high, and performance and cost need to be balanced in the design.

Fiberglass reinforced epoxy (FR-4) is a common substrate material that has good mechanical strength and heat resistance and is suitable for general radar and antenna applications. FR-4 material is relatively cheap and easy to process, making it suitable for mass production, but its dielectric properties are relatively poor, which can cause signal loss and interference.

Another common material is PTFE fiberglass composite, which combines the advantages of PTFE and fiberglass. This material has excellent dielectric properties and mechanical strength, making it suitable for high-frequency and microwave applications. However, PTFE fiberglass materials are more expensive and are typically used in applications with higher performance requirements.
