In this paper, we propose an ultra-miniaturized FSS element, which is composed of interwoven and convoluted dipoles printed on one side of a dielectric substrate. The design procedure is briefly presented. Simulations results show that the element size is reduced to 0.016λ₀ × 0.016λ₀, where λ₀ is the wavelength in vacuum at the resonant frequency. The thickness of FSS is only 0.0008λ₀. Due to the ultra-miniaturized size, the proposed FSS exhibits excellent angle-stability under both TE and TM polarizations. Furthermore, wide-band performance is also achieved, with a fractional bandwidth 73.5% under normal incidence. When the incidence angle reaches up to 75°, the central operating frequency is only shifted by 0.36%. Based on plasmon resonance, the induced currents on metallic pattern are analyzed to explain the miniaturization performance.
