AD Series™ Antenna Materials AD250C™, AD255C™, AD300D™and AD350A™ Laminate Materials Data Sheet
The AD Series antenna products are glass-reinforced, PTFE based materials that provide controlled dielectric constant, low loss performance, and very good passive intermodulation (PIM) performance. The woven glass reinforcement affords good circuit processability and enables high yield circuit board fabrication.
The AD Series antenna products are manufactured to meet the wide variety of dielectric constant options that are needed for today’s antenna requirements. Dielectric constant options are available at 2.50, 2.55, 2.60, 3.00, 3.20, and 3.50 with a typical tolerance of ±0.05. The variety of options and tight control help to enable the circuit to meet the desired impedance every time.
All AD Series antenna products are manufactured with standard electrodeposited (ED) and reverse treated ED copper foil options. This provides choices that are sufficient to help reduce both circuit losses and antenna PIM. Typical PIM values using reverse treated ED copper foil are -159 dBc at 30 mil thickness and -163 dBc at 60 mil thickness. These are typical values obtained using the extensive PIM testing capability at Rogers at 1900 MHz using a two tone, reflected method on a 50Ω microstrip test vehicle.
Additionally, the AD Series antenna products are produced in a wide variety of thicknesses. Some products such as the AD250™ laminate are available from 10 mils through 250 mils. Others are more selective and offer fewer options. Please consult with your sales engineer or customer service representative for assistance in selecting the material options that are suitable for your application.
Lastly, as PTFE based composites, the AD Series antenna materials have very low loss (typically less than 0.002 at 10 GHz), very low moisture absorption (less than 0.1%), and very high copper peel strength (greater than 10 pli).These features combined together make the AD Series laminates an ideal choice for antenna applications.
