Horn Antenna

Besides using magnetic loop antennas for compliance tests in strict accordance with standards, they can be used for engineering design and pre-compliance work.

This article presents the results of experiments to measure the effectiveness of lossy material in reducing RF emissions from perforated air vents such as those commonly used on computer enclosures. The results show good performance compared to those with conventional metal vents.

With so many different antenna options on the market, it is not always easy to understand what will work best for your application.

Antennas used for EMC testing possess several characteristics which make them ideal for use in a fast-paced, production-like EMC test environment. This article will briefly describe what these characteristics are, starting with the most important parameter – antenna factor.

In its current form, IEEE Std 149 “IEEE Standard Test Procedures for Antennas” is a marginally useful document. While the standard is a good source for interesting and pertinent information, the document has not undergone a significant update since 1979. The changes to the new version of the IEEE Std 149 will make the document an essential reference in any laboratory that conducts antenna measurements.
