| Popis: | This paper presents gain enhancement method of optical leaky wave antenna excited by parabolic reflector. This antenna uses Photonic Band Gap (PBG) as parabolic reflector to excite Grating Wave Guide (GWG). PBG reflector does not give the perfect reflection and causes the decrease of gain. We propose the gain enhancement by a new parabolic reflector combining PBG and glass layer. |
