Material for radar circuit boards
Millimetre-wave radar systems place special demands on the PCB material: it is crucial to use ultra-low-loss substrates that both minimise circuit losses and maximise antenna efficiency. The material forms the technological basis - its quality has a decisive influence on the signal integrity and measurement accuracy of the entire radar system.
By choosing the right material (e.g. special high-frequency laminates), you ensure
- Optimised high-frequency performance in the 24-86 GHz range
- Long-term stable signal transmission without degradation
- Reproducible results in series production
In millimetre wave applications, even small dielectric losses lead to significant performance losses. Our material portfolio (Rogers, Taconic, Isola) for high-frequency printed circuit boards has been specially qualified for these critical requirements.

Why radar PCBs from Multi-CB
The complexity and variety of technical parameters for high-frequency circuit carriers is enormous. Every application requires customised solutions - whether through hybrid layer structures, thermal via concepts, impedance calculations or end surfaces. It is therefore best to consult with us at a very early stage of development and benefit from our decades of experience and technical expertise. We support you from the design phase through to series production of your PCB for radar systems.
Impedance Check
The impedance defined by the customer is tested by our CAM station engineers on manufacturability. Depending on the layer buildup, the PCB layout and the customer's requested impedances a calculation model is chosen. The result is any required modification of the layer builduo and the necessary adjustments to the relevant conductor geometries.
Please also refer to our pages for impedance control of printed circuit boards.
After the manufacture of high frequency circuit boards, the impedances are checked (with a precision of up to 5%), and the detailed results are recorded exactly in a test protocol.
