A novel application of frequency selective surface in dual-band WLAN antenna

In this paper, combined elements method is introduced to achieve dual stop-band frequency selective surface (FSS). Later, a dual-band WLAN antenna is designed and the centre frequency is at 2.4GHz and 5.4GHz which accord with the FSS in this paper. We use FSS as dual-band WLAN antenna's reflection plan to improve the performance of antenna. The analysis and results of antenna and FSS are given. The results show that antenna's gain can be improved after the FSS is placed as the reflection plane. This is a new research area which have great prospect in the design of antenna combined with FSS.
