Munich, March 04, 2008 — The R&S HF907 double-ridged waveguide horn antenna from Rohde & Schwarz improves accuracy in EMI and EMS measurements. The unique, modified design of its housing ensures high and flat gain from 5 dBi to 14 dBi without any gain losses.

The R&S HF907 covers a wide frequency range from 800 MHz to 18 GHz. As a transmit and receive antenna, it can both generate disturbance and detect radiated emissions of devices under test (DUTs). During these measurements, the antenna's flat gain permits even illumination of the DUT. In EMC tests, manufacturers and operators of electronic equipment benefit from distortion free radiation patterns and obtain exact results. In the past, conventional double-ridged waveguide horn antennas exhibited gain losses at one or more points in the frequency range, which was reflected in the radiation pattern.

The R&S HF907 is compact and weighs only 1.9 kg, which makes it ideal for use in EMC labs and test chambers – especially in connection with EMC test equipment and test systems from Rohde & Schwarz.

The R&S HF907 double-ridged waveguide horn antenna is now available from Rohde & Schwarz at a price of EUR 3,750.
