<p>Electromagnetic radiating structures suitable for use as antennas or in electromagnetic field test facilities. An electromagnetic field test facility is a test enclosure used for observing the behaviour of equipment in the presence of strong electromagnetic fields and for detecting radiation from the equipment. A broadband Gigahertz field electromagnetic test facility is also disclosed in which an array of horn antennas is used to illuminate a relatively large test area at high power densities, or to measure radiation from tested equipment in a frequency range extending from DC to hundreds of Gigahertz.</p> |
