Comparison to Conventional PTFE Antenna Technologies
Rogers RO4535 is a high-frequency laminate material that is often used in antenna applications due to its excellent electrical properties and low loss characteristics. When comparing it to conventional PTFE (polytetrafluoroethylene) antenna technologies, there are several factors to consider:
1. Electrical Performance: RO4535 offers excellent electrical performance, including low dielectric loss and high frequency stability. It has a low dissipation factor, which means that it exhibits low signal loss and high signal integrity. This can result in improved antenna efficiency and better overall performance compared to conventional PTFE materials.
2. Frequency Range: RO4535 is designed for high-frequency applications, typically ranging from a few gigahertz (GHz) up to tens of GHz.
