TX RX Technology New broadband EMC double-ridge

horn antenna Broadband antennas, due to the large frequency bands required by standards, are the work horse of electromagnetic compatibility testing. Traditionally the antenna parameter of interest to the EMC engineer was the antenna factor. The advent of higher frequency testing has brought the development of a new double-ridge guide horn design. By Vicente Rodriguez adiated immunity or susceptibility and radiated emissions areR the two main types of radiated EMC measurements. Antennas are used in radiated EMC testing to sense and generate fields. International and national standards have defined the test distance, the antenna to be used, and the location of the equipment [1]. For years the EMC engineer paid little attention to the pattern of the antenna being used. The engineer would have an idea of the direction of the main beam and would point the antenna to the equipment under test (EUT) so that this fell under the main beam
