PREPERM™ is the right solution for 5G applications

Are you ready for the future? We are.

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. The 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.

We are involved in the Nokia Bell Labs driven LuxTurrim5G project developing and demonstrating fast 5G network based on smart light poles with integrated antennas, base stations, sensors, screens and other devices.

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).

PREPERM™ benefits

  • 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! 

PREPERM™ benefits

  • 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.

PREPERM benefits

  • 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?

Energy consumption

5G requires a high density small cell base stations network, which requires cost effectiveness and low operation power.​ In this, material homogenity and dielectric losses are of essential importance.

Fast and reliable Gigabit wireless

Low losses are mandatory in WiGig since the in-room WiGig products will operate in 60 GHz frequencies.  Low loss PREPERM™ materials enable the most reliable link between mobile device and computer.

High resolution and reliability

The extreme reliability and high resolution are necessities for traffic safety and security applications. mmWaves provide perfect solution as long as the material losses have been minimized.

Antenna gain in mmWave backhaul
Narrow directive antenna beam reduces interference and allows the reuse of the frequencies on different nearby regions while minimizing reductions in communications speeds.

Isotropic material with stable dielectric properties and ultra low loss enables best antenna performance.
