Convoluted dipole array elements

A single layer ultra-miniaturized FSS operating in VHF

“…To reduce the element size, a class of convoluted FSS structures was extensively investigated [11]- [17]. In [11], several convoluted dipole array elements were introduced to produce low-frequency resonances in a small periodicity surface.…”

“…In [11], several convoluted dipole array elements were introduced to produce low-frequency resonances in a small periodicity surface. In addition, the convoluted FSS elements improve the angle stability, keeping the operating bands far away from the grating region determined by the periodicity of the array.…”

“…The rotated linear dipoles arrays are one of the simplest configurations for designing frequency selective surfaces [25]. The initial purpose of using rotated linear dipoles was to keep the operating bands away from the grating region determined by the periodicity of the array [11]. For a given periodicity, the length of the dipole is about λ/2, where λ is operating wavelength.…”

Minimal size of operation of fractal FSS

“…4,5]. Convoluted frequency selective surfaces are a class of complex array elements which exhibit long wavelength resonances in a surface with electrically small periodicity [6]. The use of convoluted elements improved the angular stability of the frequency responses of the surface, moving the operating bands away from the grating region which is determined by the periodicity of the array.…”

“…The use of convoluted elements improved the angular stability of the frequency responses of the surface, moving the operating bands away from the grating region which is determined by the periodicity of the array. The concept was introduced in [6] and developed further in [7], where the element configurations included sequences of fractal Hilbert space filling curves and also in [8] which introduced a scheme for convolving crossed dipoles.…”
