Abstract


Electromagnetic Band-Gap (EBG) structures are a popular and efficient technique for microwave applications. EBG may be combined with microstrip antenna to increase the diversity gain, the radiation efficiency and/or to suppress surface waves, to reduce the side lobes of the radiation pattern and to increase the bandwidth. In this paper, two different structures will be presented and discussed, which involve: (1) EBG structure fed by circular patch antenna, and (2) circular patch antenna surrounded by one row of EBG structure. The influence of the EBG structure on the radiation patterns is investigated. The effect of the surface waves is also considered. Finally, the reduction of the side lobes of the radiation pattern to increase the bandwidth is presented.
