Mi-Waves double ridged horn antenna design is one of the best in the world. Our double ridge horn antennas are manufactured with the highest quality engineering materials and procedures to ensure top notch design needs.
If you are investingating more design needs. The IEEE has a whitepaper with a classic design of 1-18 GHz DRHA with exponential ridges that is modeled with the antenna pattern deficiencies and detected at frequencies above 12 GHz. The antenna pattern is optimized by modification of the antenna structure.
The impedance matching is affected and the VSWR is increased at the frequencies below 2 GHz. Read more about this at the IEEE.
