A single metal layer, multifunctional frequency selective surface with a very simple pattern of the unit cell, containing a U-shaped metal resonator on FR4 substrate, and working in the low GHz frequency range is proposed. The structure realizes dual linear polarization filtering at frequencies of 1.83 and 4.14 GHz with fractional bandwidths of 34.15% and 22.51% respectively, and linear-to-circular polarization conversion at 2.68 GHz, with 3.2 dB insertion loss (IL), 30-45 • angular stability depending on the direction of arrival of the incident wave, and 22.01% axial ratio bandwidth. The dimension of the unit cell corresponds to 0.09, 0.13 and 0.21 fractions of wavelength at the three operational frequencies. The functionality of the proposed structure is assessed by simulation, circuital model, and experiment in anechoic chamber. Scalability is demonstrated by designs that work at different frequencies, tested by simulation.

“…10,11 Circularly polarized waves can be obtained in two ways, one is CP source antennas, and the other is converted by linearly polarized (LP) waves. 12 For the first way, multiband CP waves generation needs multi-feed or shared aperture antennas, which are considerably difficult to handle. Therefore, multiband CP waves can be achieved by conversion phenomenon in which LP waves generated by an antenna are converted to multiband CP waves using multiband linear polarization to CP (LP-to-CP) converter.…”

In this article, a triple-band linear-to-circular transmissive polarization converter based on metasurface is proposed, which can transform a linearly polarized incident wave into right-hand circularly polarized wave and left-hand circularly polarized wave in three nonadjacent frequency bands. Since the proposed polarization converter has a novel structure with only one metallic layer, the proposed converter is ultrathin. After simulating, the results demonstrate that the axial ratio of the proposed transmissive circularly converter is below 3-dB in 7. GHz. Additionally, the physical mechanism of multiple resonances is discussed based on equivalent circuit model. Moreover, a prototype is fabricated and measured; the experimental and simulation results are in good agreement. This polarization converter can be employed to manipulate the polarization state of signals in microwave communication.

“…In the reference [4], a Jerusalem cross structure was designed to realize the conversion of linearly polarized waves into circularly polarized waves, which achieved an axial ratio bandwidth performance of 4.3%. Then, variations of its multi-layer structure were proposed in [5][6][7][8] for performance improvement. References [9] and [10] exploited metal spirals and metal through-holes to design 3-D circular polarizers.…”

This paper proposes a broad-band linear-to-circular polarization converter based on a multilayer stripline metasurface. The structure is constructed of three stripline metallic layers stacked with two dielectric plates, and it has different electromagnetic response characteristics in two orthogonal directions. Based on this, the amplitude of the two orthogonal components of the transmitted wave is equal, and the phase difference is 90°. To better understand the working principle of the proposed converter, a detailed equivalent circuit model is presented. The simulation results indicate that the converter can convert linearly polarized incident waves into circularly polarized transmitted waves in the frequency range of 4.96-12.44 GHz. For an increased incident angle of 50°, the device can still maintain an axial ratio bandwidth of 53.7% in the x-z and y-z planes. Because of its broadband, small size, and wide-angle, the proposed converter can be integrated into a linearly polarized antenna system to generate circularly polarized waves without significantly affecting antenna performance.
