Abstract
In this paper, we propose the new bow-tie antenna design method, which realizes the wideband and high gain antenna element for the shared aperture antenna on airborne radar. In order to improve the common bow-tie antenna characteristics, we propose four improvement approaches. The details of improvement approaches are presented. We built the prototype array antenna composed of 64 elements designed, and demonstrated that it had significant improvement on the antenna element gain over 6 to 18 GHz.
