Pyramidal Absorber Foam – Key Features and Applications

What is a Pyramidal RF Absorber?

Pyramidal Absorber Foam is a high-performance RF and microwave absorbing material specifically designed to minimize unwanted electromagnetic reflections in test environments. It is widely used in anechoic chambers, antenna test labs, and EMC compliance testing facilities. Thanks to its unique pyramid-shaped geometry and lossy material composition, it offers excellent absorption across a broad frequency range, ensuring more accurate and repeatable measurements.

By reducing unwanted reflections, this absorber enhances measurement accuracy and ensures optimal performance in RF testing environments.

Types of Pyramidal RF Absorbers

Pyramidal RF absorbers come in different shapes and materials. For instance, Each type has distinct advantages, making them suitable for specific purposes. The most common types include:

• Pyramidal Absorber Foam: High-performance absorption, commonly used in antenna test chambers.
• Honeycomb Absorbers: Lightweight and efficient for specialized RF applications.
• Flat Sheet Absorbers: Used for EMI shielding and general-purpose absorption.
