New wideband horn antenna caters for EMC test applications from 200MHz to 2GHz

Link Microtek, a manufacturer of RF and microwave components and subsystems, has introduced a new open-sided, linearly polarised horn antenna that operates over the wide frequency range 200MHz to 2GHz.

Intended primarily 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 250V/m at 1m and a nominal impedance of 50 ohms. It also offers impressive gain uniformity, with gain only varying from 5 to 9dBi 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.

The AM0.2-2HA antenna is fabricated from aluminium to provide a rugged, corrosion-resistant construction. It measures 980 x 980 x 730mm, yet weighs only 12kg.
