The Importance of Antenna Beamwidth in RF Testing

Antenna beamwidth determines the expected signal strength given the direction and radiation distance of an antenna. The beamwidth will vary given a number of different factors such as the antenna type, design, orientation, and radio frequency. Understanding beamwidth and how it influences a test environment is critical to accurate and repeatable tests.

Questions to Ask When Looking for an EMC Immunity Antenna

Antennas come in many different types, and it can sometimes be overwhelming to decide which one fits the need the best. In the case of immunity antennas, the correct selection may be the difference of reaching field and not. The antenna is the most important part of the system. Given that the amplifiers can be the costliest part of the system, one needs to take the time to research and find the correct antenna to make the best use of the available power.

Requirements of Antennas for EMC Testing

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.

Dipole-Type Antennas in EMC Testing

This two-article series is devoted to a dipole family of antennas used in EMC testing: half-wave dipole, quarter-wave monopole, log-periodic, and biconical antenna. Part I presents the antenna models and the construction details.

Let’s Talk About… Baluns

What is an antenna Balun? The term balun is a portmanteau (a blending of two words) of balanced/unbalanced – BAL-UN.
