Given consumer and corporate trends, products of all types are increasingly likely to incorporate electronics in the form of processors, memory chips, and various types of wireless communications. Any such product—whether a car, toaster oven, programmable logic controller, or cell phone—might generate RF interference, whether it intentionally transmits and receives RF signals as part of its functions or not. According to governments all over the world, that is a problem. Product designs incorporating electronics frequently fall subject to governmental regulations and so more companies must conduct compliance testing.
Companies in consumer electronics, industrial controls, embedded computers, and similar areas are typically experienced in such testing and know how to incorporate it into their R&D activities. However, companies that are new to compliance testing need to learn effective testing methods and acquire equipment, including antennas. There are many types of antennas, but for most companies, the first investment should be in a bilogical antenna for the following reasons.
