Abstract
A single layer tri-band frequency selective surface (FSS) is proposed in this paper. It is composed of two transmission poles and one stop band filter, thus behaving as good isolation between two transmission bands .i.e. C and X-band. The design consists of two square slots with a center square patch and two cross dipole patch diagonally arranged in a two-dimensional unit cell. Two band pass filter is at 6.04 GHz and 9.60 GHz resonant frequency with a band width of 0.89 GHz and 0.87 GHz respectively. One stop band filter at 7.6 GHz resonant frequency in between these C-band and X-band play an important role for the good isolation for wireless communication. The size of unit cell FSS is 0.40λ<inf>0</inf>×0.40λ<inf>0</inf> and thickness of 0.016λ<inf>0</inf>, where λ<inf>0</inf> is the first lower resonant frequency. Both pass band resonant frequencies are spaced with a good shielding providing the frequency ratio of 1.57.
