The Dual-Ridged Horn Antenna

摘要

The dual-ridged horn antenna (DRHA) is a workhorse in EMC and antenna pattern measurement laboratories. Its broad band allows the user to test over a large range of frequencies without changing antennas. However, these antennas came under scrutiny when Burns, Leuchtmann, and Vahldieck showed the pattern problems of these antennas at the upper end of the band. Their work illustrated that these types of horns have problems with the integrity of the main lobe of the pattern.
