Innovative polymer solutions for high-frequency waveguides
&w=3840&q=75)
The POLYWISE project is developing new materials and manufacturing concepts for the next generation of high-frequency sensor and communication systems.
Rapid advancements in sensor and communication technology are placing new demands on materials and systems. Increasing frequencies up to several hundred gigahertz enable higher data rates and more precise measurement systems—but also present technical challenges. In the POLYWISE project, we are working on new polymer solutions and manufacturing strategies to efficiently and sustainably realize the next generation of waveguide systems.
Challenge
As frequencies increase, conventional transmission systems such as cables quickly reach their limits. Signal loss, material limitations, and rising costs make their use in modern applications difficult.
Particularly critical factors here are:
precisely adjustable permittivity
temperature stability of the materials
reliable signal transmission at high frequencies
Especially in the automotive sector, systems must also reliably operate across extreme temperature ranges from –40 °C to +105 °C.
Solution
Dielectric waveguides (DWG) offer an innovative alternative to traditional cabling systems. They are made of polymer-based materials and contain no metallic components.
This results in significant advantages:
reduced material costs
lower weight
improved recyclability
new design and integration possibilities
Innovation
POLYWISE focuses on the development of new polymer compositions with precisely tunable properties. These are combined with innovative manufacturing and processing concepts.
The goal is to create an optimized waveguide that:
transmits high-frequency signals with low loss
offers stable electrical properties
is scalable for industrial applications
Usage
