An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. The AF varies with frequency at the same presented field strength, but at a different frequency, the produced voltage at the connector is not constant. This white paper explains the process of creating AF data and how to use it.

The increasing availability of COTS RF modules and subsystem components has made it convenient to design and assemble a custom high-performance RF communications system from off-the-shelf parts. However, while availability and selection has increased, top-of-the-line performance is still expensive. Being familiar with each category of RF subsystem modules and the various roles these modules play is critical to understanding how they can be used to optimize a system’s performance.
