Radiated emission measurements are always performed in laboratories at Open Area Test Sites or in anechoic chambers at 10 or 3 m in accordance with the standard EN55022 or other similar standards. However, it is not always possible to use laboratories because of some limitations. If the Equipment Under Test has large dimensions or heavy, it is not possible to use laboratory facilities during tests. As a consequence, on‐site radiated emission tests are required in industry. However, radiated emission tests have many challenges in industry such as background noise, uncontrolled reflections and narrow testing environment, for that reason EMC testing is very challenging at 3/10 m and close distance testing at non‐standard distances becomes unavoidable in industry. In this research, we have experimentally investigated the relation between measurement results at close distance and standard distance for certain types of antennas. © 2016 Wiley Periodicals, Inc.
