Low Compression Conductive Foam

A new EMI shielding material from Leader Tech significantly improves the quality and performance of die-cut enclosure gaskets. The Company’s low compression CFS Conductive Foam Shielding material is manufactured in sheets that have a low-resistance polyester fabric surface and a resilient Nickel-Copper polyurethane foam center.

These characteristics make CFS the ideal choice for intricate die-cut finishing operations found in many I/O panel, backplane and access panel applications. A standard conductive, pressure sensitive adhesive facilitates fast and easy installation.

Leader Tech’s CFS gaskets offer a typical Shielding Effectiveness of 60dB between 10MHz-3GHz. In addition, the conductive foam exhibits a compression load of 2.1 psi at 30% compression and has an operational temperature range from -40°F to +156°F.

Near and Far Field Measurements with a Vector Network Analyzer

For optimal performance in over-the-air RF systems, antennas must meet specific requirements. Performance parameters like size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Methods of measuring the transmission (or reception) pattern that determines antenna gain with a VNA will be examined in this article.
