77 GHz Radar Board

Automotive mmWave radar on Rogers RO3003. Move the slider — patch antennas and array pitch shrink with λ/2 as frequency climbs. FR-4 can't play here: 15× higher loss at mmWave.

Material comparison

Rogers RO3003 (automotive)✓

Er = 3.0 / tanδ = 0.0013 / Tg = 280 °C

Low-loss, thermally stable, proven on automotive 77 GHz lines.

FR-4 (commodity)✗

Er = 4.2 / tanδ = 0.02

15× more dielectric loss at mmWave. Not usable here.

ADAS → LiDAR → 77 GHz radar is the next frontier.

FQC supports the full Rogers stack (RO3003 / RO4350B) plus Megtron for autonomy-grade boards.
