In 5G communication systems, antenna performance directly impacts signal coverage, efficiency, and data throughput. Selecting the right PCB material is critical, especially for sub-6 GHz and high-speed RF antenna designs. RO4003 PCB for 5G antenna applications is widely adopted due to its low loss, stable dielectric properties, and excellent manufacturability.
Compared with conventional FR-4 materials, RO4003 PCB delivers more predictable RF performance, making it an ideal choice for professional 5G antenna designs.
Overview of RO4003 PCB Material
RO4003 PCB is based on Rogers RO4003C laminate, a hydrocarbon ceramic composite designed for RF and microwave circuits. Key electrical characteristics include:
-
Dielectric constant (Dk) around 3.55
-
Low dissipation factor (Df ≈ 0.0027 @ 10 GHz)
-
Excellent thermal stability and low moisture absorption
-
Consistent performance across temperature and frequency
These properties make RO4003 PCB for 5G antenna designs highly reliable and repeatable.
