Introduction
Rogers’ AD250C antenna laminates are high-performance, specialty materials designed specifically to meet the needs of today's wireless antenna markets.
These laminates are made from glass-reinforced, PTFE-based materials that offer a controlled dielectric constant, low loss performance, and excellent passive intermodulation (PIM) characteristics. The woven glass reinforcement enhances circuit processability, enabling efficient circuit board production with high yields.
AD250C antenna materials come with options for standard electrodeposited (ED) or reverse treated ED copper foil, allowing for choices that help minimize circuit losses and improve antenna PIM.
Features
AD250C antenna materials offer several notable features:
These materials have an impressively low loss tangent of 0.0013 at 10 GHz and base station frequencies, ensuring minimal signal degradation.
They provide a dielectric constant (Dk) of 2.50, with a tolerance of +/- 0.04, enabling precise control over signal propagation characteristics.
The use of low-profile copper helps to reduce conductive losses, enhancing overall antenna efficiency.
AD250C exhibits very low moisture absorption of 0.04%, ensuring consistent performance and integrity across diverse environmental conditions.
A very high copper peel strength of 14.8 lbs/in ensures reliable adhesion between the copper and the substrate, enhancing the antenna’s durability and performance in challenging applications.
