An approach to synthesizing wideband ultraminiaturised-element frequency selective surface (UMEFSS) based on interlocked 2.5-dimensional (2.5D) structures is proposed. Ultraminiaturisation and wide stopband response can be realized due to compactly staggered arrangement of 2.5D elements. The element size of the proposed UMEFSS is reduced to 0.033λ0×0.033λ0, and fractional bandwidth attains 99.8%. Stable response is achieved under oblique incidence at different polarisations. The results show a satisfactory consistency between full-wave simulations and experiments.
