This paper presents gain enhancement of leaky wave antenna by parabolic reflector of photonic crystal. A leaky wave antenna has been proposed as an antenna for optical wireless communication. This antenna is excited by a parabolic reflector made of photonic crystals. This excitation method is very compact, resulting in some insertion loss. To improve the drawback, we propose a new reflector combined by photonic crystals and glass layer.
