An Ultra Wide Band Quad Horn Antenna with Different Ridges Profiles

In this article, an ultra-wideband quad ridge horn antenna, covering two full successive bands, specifically K and Ka bands is introduced. The proposed antenna can carry vertical and horizontal signals simultaneously with a deep matching level over the entire band. The introduced antenna shape is proposed based on a mathematical formulation that minimizes the discontinuity between the feeding structure and the horn. The presented work has a stable gain characteristic to facilitate the utilization as a reflector feeding.
