The next generation mobile networks are already on our doorsteps
After years of talk and preparation, this year we will finally see the roll-out of 5G. With its download speed of up to 10 gigabits per second, 5G is able to meet the future requirements for data speed and low latency.
The list of 5G usage scenarios starts naturally with mobile usage and the improved broadband. In traffic, there is an increasing need for V2V (vehicle-to-vehicle) communication. In addition, 5G makes cities smarter and opens up new possibilities in remote health care and IoT. The increased demand for data capacity and low latency and the growing volume of connected devices require more base stations and higher frequencies. The antennas need to be unnoticeable, steerable and precise, not to mention energy-efficient with ultra-low losses.
All of this puts pressure on the materials - dielectric properties and low losses are more important than ever. Premix’s PREPERM® portfolio offers a wide variety of dielectric constants and is the right solution for high-class 5G applications.
The dielectric measurement data up to 220 GHz indicates that the dielectric properties of PREPERM® are stable and not dependent on the frequency. PREPERM® solutions enable faster, safer and more reliable connections - in antennas, lenses, screws or other RF parts.
Excellent RF performance combined with moldability
PREPERM® radome grades are designed to have excellent RF performance combined with high impact strength and moldability. They are available in black (RB) and sand (RS) colors, with different special properties such as high impact strength (HI) and flame retardancy (FR).
- Low dielectric constant and losses
- Isotropic material - no glass fibres
- Made for injection molding
Lenses and radiating antenna elements (DRAs)
Better gain, smaller design
PREPERM® grades have stable and well controlled dielectric constants from 2.6 up to 23. With higher permittivity you can achieve improved isolation and better gain while reducing the size!
- Stable and controlled dielectric constant - from 2.6 to 23
- Very low losses even at mmWaves
- Can be injection molded or machined
Screws and fasteners
Lower losses, water absorption and price
Plastic screws are needed in many applications in the telecom industry – in RF filters, RF combiners and antennas. PREPERM® screws are used for example as a transparent fastener in filters, printed circuit boards or radar elements and as tuning elements.
- Very low losses
- Low water absorption
- Competitive price
mmWaves build safe and ultra-connected societies
Safe and ultra-connected societies are not born by themselves - and certainly not without any challenges. How do we overcome the challenges with the right material choice?
