“…Actually, stable frequency filter of FSS radome can be obtained by improving the stability of resonant frequency and bandwidth, simultaneously. The resonant frequency stability can be obtained by miniaturised FSSs [5,6,7,8,9,10,11] and the bandwidth stability can be improved by bounding outer compensation layers with a lower permittivity [1]. However, when fabricating the bandwidth compensation layers, mechanical suitable materials with such a lower permittivity may be not available in engineering.…”

In this paper, a feasible compensation technique has been proposed to improve the bandwidth angular stability of FSS radome. Stacked structure composed of different mechanical suitable materials has been adopted to construct the bandwidth compensation layer in the proposed technique. Hence, the problem that mechanical suitable materials with lower permittivity are not available in the classic bandwidth compensation technique has been solved. The validity of the proposed technique is verified by designing an FSS radome composed of modified second-order miniaturised FSS (MFSS) and bandwidth compensation layers. Simulation results show that the proposed technique has equal performance in stabilizing the bandwidth of FSS radome under oblique incidence with the classic one.

“…A novel miniaturized FSS is achieved by bending the edge of square loop aperture into the inner space is proposed in [5]. A convoluted ring slot is adopted to construct miniaturized FSS in [6], miniaturized FSSs based on metallic meander lines are proposed in [7][8][9][10], and compact miniaturized FSS based on Y-type element is proposed in [11]. Also, substrate integrated waveguide (SIW) technology [12], lumped reactive components [13] and complementary structures [14] are applied to realize the miniaturization of FSS.…”

Abstract-A compact miniaturized frequency selective surface (FSS) with stable resonant frequency is proposed in this letter. The proposed FSS is composed of four spiral triangles connected in the middle of the unit cell, symmetrically. Simulated results show that the dimension of the element is only 0.0558λ 0 × 0.0558λ 0 , and reduction in FSS size is up to 97.7% with respect to conventional cross-dipole FSS operating at the same frequency of 2.7 GHz. Also, the proposed FSS has great angular stability, and the resonant frequency deviation keeps below 0.4% for both TM and TE polarizations of 60 • incident angle.

“…Adding meander-slots to the circular ring structure can make FSS array element dimensions much smaller than the wavelength [12]. A miniature FSS by printing micro wire on a dielectric has been demonstrated in [13]. Printing four symmetrical spiral patterns of metallic meander lines can increase the electrical length of array element and enhance the value of resonant components [14].…”

A novel approach to design a miniaturized frequency selective surface (FSS) is proposed. The miniaturization is achieved by enhancing the inductance of the proposed stepped-impedance array element. This enhancement is done by using a micro-wire and controlling the path of the current which passes through the metallic surface of the element. As a result, the dimensions of the miniaturized element are much smaller than the wavelength at the resonant frequency. The proposed FSS consists of a single metal layer on a dielectric substrate with a simple configuration. Through an example with a pass-band at 3GHz, it is demonstrated that a stable resonant frequency response under various incident of angle (up to 88 o ) can be achieved, which is the most attractive feature of this design. Also the proposed design has the same response for the Transverse Magnetic (TM) and Transverse Electric (TE) modes. In addition, a single polarized FSS with simple configuration is exhibited. The miniaturized element is much smaller than the wavelength (up to 0.055 λ ). It displays insensitive frequency response of different angle of incident wave.
