ENGINEERING ANSWER
At 24 GHz, trace geometry, launches, antenna structure and fabrication tolerances deserve close attention. A material’s broad RF use does not replace a frequency-specific loss and tolerance assessment.
What to decide before release
Evaluate the exact foil and stackup with EM simulation and representative coupons. Include the radome or enclosure when assessing antennas. Coordinate the RF drawing with fabrication capability before committing to fine features.
Checks to put in your design brief
- Validate the dielectric model at the band
- Include the antenna environment
- Measure representative hardware
Important distinction
Do not extrapolate a low-frequency impedance check into a guarantee of radar performance.
