The RO3003G2™ from Rogers Corporation are Ceramic-Filled PTFE Laminates for mm-wave automotive radar applications. The combination of optimized resin and filler content along with the introduction of very low-profile ED copper translates to a Dk of 3.00 @ 10 GHz (clamped stripline method) & 3.07 @ 77 GHz (microstrip differential phase length method). These laminates have an insertion loss of 1.3 dB/inch for 5 mil laminates as measured by the microstrip differential phase length method. The laminates can be fabricated into printed circuit boards using standard PTFE circuit board processing techniques with minor modifications. They are suitable for use in adaptive cruise control, forward collision warning, active brake assist, lane change assist, traffic jam pilot, parking pilot and blind spot detection applications.
