Wideband horn antenna for EMC tests spans 200 MHz to 2 GHz

October 18, 2016 // By Graham Prophet
Link Microtek, manufacturer of RF and microwave components and subsystems, has introduced an open-sided, linearly polarised horn antenna that operates over the wide frequency range 200 MHz to 2 GHz.

Primarily intended for EMC test applications, the AM0.2-2HA antenna can be used as either transmitter or receiver for measurements of products’ immunity or emissions in accordance with international EMC standards laid down by organisations such as IEC, ISO and CISPR.


The antenna can handle up to 200W of microwave power and features a low average VSWR of 1.6:1, a field strength capability of 250 V/m at 1m and a nominal impedance of 50 Ohms. It also offers excellent gain uniformity, with gain only varying from 5 to 9 dBi over the entire operating frequency range.


The horn antenna is equipped with a precision N-type female connector and a mounting bracket that enables the user to switch between vertical and horizontal polarisations. A standard camera thread allows easy mounting on a wide variety of tripods. Designed and manufactured at Link’s premises in Basingstoke, UK, the AM0.2-2HA antenna is fabricated from aluminium to provide a rugged, corrosion-resistant construction. It measures 980 x 980 x 730 mm, and weighs 12kg.
