What is The Rogers AD Series™ Antenna Laminates?
These AD250C™, AD255C™, AD300D™ and AD350A™ Series antenna materials from Rogers Corporation are high-performance, specialized materials meticulously engineered and manufactured to address the stringent demands of contemporary wireless antenna markets. Rogers provides materials that not only meet current design requirements but also anticipate future needs.
These AD250C™, AD255C™, AD300D™ and AD350A™ Series antenna products are glass-reinforced, PTFE-based composites that offer controlled dielectric constants, low-loss performance, and superior passive intermodulation (PIM) characteristics. The woven glass reinforcement ensures excellent processability during circuit fabrication, thereby enhancing yield rates in circuit board production.
Manufactured with a range of dielectric constant options, the AD Series antenna products cater to diverse antenna requirements. This versatility, combined with precise control over material properties, ensures consistent achievement of desired impedance specifications. All AD Series antenna products are available with standard electrodeposited (ED) or reverse-treated ED copper foil options. These choices are designed to effectively minimize both circuit losses and antenna passive intermodulation (PIM).
As PTFE-based composites, the AD Series antenna materials exhibit exceptionally low loss (typically less than 0.002 at 10 GHz), minimal moisture absorption (less than 0.1%), and high copper peel strength (exceeding 10 pli). These characteristics collectively render the AD Series laminates an optimal choice for antenna applications.

Features of The Rogers AD Series™ Antenna Laminates
Ultra-Low Loss Tangent (<0.002 at 10 GHz)
A low loss tangent ensures minimal signal loss at high frequencies, which is critical for maintaining signal integrity and achieving high-efficiency performance in antenna systems. Minimizes signal attenuation, making it ideal for high-frequency applications where efficiency is paramount.
Tight Dielectric Constant Control (±0.05)
Tight control over the dielectric constant is essential for predictable impedance and consistent performance across different batches, contributing to reliable antenna designs. Ensures consistent impedance matching and predictable performance across designs, reducing prototyping iterations.
Very Low PIM (-159 dBc at 30 mil, 1900 MHz)
With PIM levels as low as -159 dBc (30 mil, 1900 MHz), these laminates mitigate interference in multi-carrier systems, crucial for 5G and LTE networks. Excellent antenna performance and reduced yield loss due to PIM related issues. The extremely low passive intermodulation (PIM) levels help to prevent unwanted interference and maintain the purity of transmitted signals, which is particularly important in densely populated frequency environments.
Excellent Dimensional Stability
Dimensional stability ensures that the laminates maintain their physical dimensions under varying environmental conditions, thereby supporting long-term reliability and consistent performance in demanding applications.
