In this paper, a novel band-pass miniaturized FSS is proposed, in which a unit cell consists of four spiral etched slot lines arranged central-symmetrically on a dielectric substrate, and the spiral elements are placed interlaced so that each element is connected to an adjacent one in another unit cell. Simulation results show the FSS has the dimension of a unit cell only 0.060λ×0.060λ, where λ represents...
Unlike the traditional two-dimensional periodic arrays, a novel cubic frequency selective surface is proposed. For each unit, metal strips of a novel pattern are placed on dielectric substrates, and together form the six faces of a FSS cube, which is put in the middle of dielectric cubes. Simulation is conducted to analyze the characteristic of the FSS, and results are compared with traditional single-layer...
A novel multi-band frequency selective surfaces (FSS) based on fractal triangle elements is proposed. The structure consists of three regular triangles placed into a larger one and many nesting triangles of different lengths and apex angles inside in front of a dielectric slab. Simulation by CST MICROWAVE STUDIO® is conducted to analyze the characteristics of the structure. The results show that the...
A series of novel miniaturized frequency selective surfaces (FSS) are proposed. The unit cells of the structures consist of four rectangle spiral-shaped frequency selective surfaces arranging differently on the interface of a dielectric slab. Simulation by CST Microwave Studio is conducted to analyze the characteristics of the structure and performances are compared to that of the meander line. The...
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...
