Abstract :
This paper presents a two-layered antenna with dual frequency for indoor micro cellular system. It consists of a upper loop and a bottom center feed patch antenna. FDTD analysis shows that this antenna has two resonant frequencies and the radiation patterns are similar to monopole antenna
