Abstract
In this paper, miniaturization technique using modified lens with curved surfaces is introduced to avoid enlargement of COBRA (coaxial beam rotating antenna) horn for high power electromagnetic applications. By using this technique, the length of horn antenna of 2700 mm can be reduced as 600 mm without reduction of gain. The designed antenna applied this technique has gain of 27.80 dBi and circular polarization at boresight.
