In this paper, a new design of band-reject frequency selective surfaces is proposed. Compared to previous compact structure, the FSS proposed has a better firm performance with the dimension of a unit cell only 0.126λ × 0.126λ, where λ represents the wavelength of the resonant frequency. Above design is aimed at rejection of WLAN band (5.15–5.725) GHz. Moreover, the proposed design has a stable response...
In this letter, a new design of compact band-reject frequency selective surfaces is proposed. Compared to previous compact structures, the FSS proposed has a better compact performance with the dimension of a unit cell only 0.082λ ×0.082λ, where λ represents the wavelength of the resonant frequency. Above design rejects Wimax band (3.3-3.8) GHz. Moreover,...
A compact and microstrip-fed ultra-wideband antenna with band rejection characteristics is proposed. Band stop property is realized using a balanced slot. The range of stop band can be adjusted using length and width of inserted slot. The simulated impedance bandwidth of proposed antenna is from 3.2 GHz to 10.65 GHz for VSWR < 2 while having the band rejection characteristics in the frequency range...
