In this paper, a novel miniaturized periodic element for constructing a bandpass frequency selective surface (FSS) is proposed, which has better miniaturization performance with the dimension of a unit cell only 0.061 λ × 0.61, where λ represents the wavelength of the resonant frequency.Abstract:
In this letter, a novel miniaturized periodic element for constructing a bandpass frequency selective surface (FSS) is proposed. Compared to previous miniaturized structures, the FSS proposed has better miniaturization performance with the dimension of a unit cell only 0.061 λ × 0.061 λ , where λ represents the wavelength of the resonant frequency. Moreover, the miniaturization characteristic is stable with respect to different polarizations and incident angles of the waves illuminating. Both simulation and measurement are taken, and the results obtained demonstrate the claimed performance.read more
