“…According to the table, our proposed design has poorer performance compared to multilayer cases, especially in the insertion loss performance. However, our design shows comparable performance in insertion loss with those single-layer polarizers in [11], [13]- [15], but with much wider 3-dB AR bandwidth.…”

“…The measured insertion loss is between 2.5 and 3 dB in the band 18-29 GHz. Table I shows the comparison between our proposed design and a number of published single-layer polarizers in [11], [13]- [15] and multilayer polarizers in [5], [11], [12], and [17] in terms of 3-dB AR bandwidth and maximum insertion loss in the operating band. According to the table, our proposed design has poorer performance compared to multilayer cases, especially in the insertion loss performance.…”

VII. CONCLUSIONReflective diffractive gratings have numerous applications in optics and in electromagnetism, but their thickness can be a problem for applications at VHF frequencies or lower. We present a solution to this problem in the form of a thin diffractive panel that comprises resonant elements. A particular implementation was designed and tested for applications to prevent building perturbations to aircraft ILS. The screen measured only 1/34th of a wavelength in depth (1/15th of a wavelength with its protective weather screen). Measurements for an angle of incidence from 50 • to 55.5 • with respect to the plate normal displayed a 91% reduction in scattered field in dry conditions and a 90% reduction in simulated extreme weather conditions.The technology was developed with a particular application in mind; therefore, the main driver was whether it could be implemented simply and cheaply for applications in the VHF band. We did not pursue designs with thicknesses less than 1/34th of a wavelength as these were found to have a reduced bandwidth due to the reduced inductance. The tradeoff between thickness and bandwidth should be studied on a case-by-case basis for other applications. A video of the field trials is available on the Airbus website [12].Abstract-A new single-layer linear-to-circular polarizer is presented in this communication. A novel hybrid meander line and loop configuration is employed to transform linearly polarized field to circularly polarized field over a wide frequency band. Numerical simulations indicate that the proposed polarizer is robust under oblique and deflected illuminations. A prototype of the proposed polarizer is designed and fabricated. Measured results show that the band of axial ratio less than 3 dB ranges from 18 to 29 GHz with about 3-dB insertion loss.

“…High gain CP antennas can be obtained either by increasing the gain of a CP antenna with the help of reflectors and superstrates [2][3][4][5] or by using a polarizer to convert LP radiations from an antenna to CP radiations [6][7][8][9]. High gain of the printed CP antenna can also be achieved by using array structure, but it requires a complex feeding network [10,11].…”

“…Some polarization converters were designed and presented in [1]- [15], where some converters were designed using frequency-selective surface (FSS) [1]- [11] and the others were designed based on metasurfaces [13], [14]. In [15], the rotating frequency-selective surface was designed based on the substrate integrated waveguide (SIW) technology.…”

“…The bandwidth of AR less than 3 dB up to 21% was achieved with the one layer perforated screen design. An insertion loss of 1.1 dB can be achieved for the split circular ring double-layer periodic array [11]. The other potential methods, except the common ones, using anisotropic impedance surfaces to design the polarizer were also described in [12]- [14].…”

| In this paper, a novel polarization-reconfigurable converter (PRC) is proposed based on a multilayer frequencyselective surface (MFSS). First, the MFSS is designed using the square patches and the grid lines array to determine the operational frequency and bandwidth, and then the corners of the square patches are truncated to produce the phase difference of 90 between the two orthogonal linear components for circular polarization performance. To analyze and synthesize the PRC array, the operational mechanism is described in detail.The relation of the polarization states as a function of the rotating angle of the PRC array is summarized from the principle of operation. Therefore, the results show that the linear polarization (LP) from an incident wave can be reconfigured to LP, right-and left-hand circular polarizations by rotating the free-standing converter screen. The cell periods along x-and y-directions are the same, and their total height is 6 mm. The fractional bandwidth of axial ratio (AR) less than 3 dB is more than 15% with respect to the center operating frequency of 10 GHz at normal incidence. Simultaneously, the AR characteristics of different incidence angles for oblique incidence with TE and TM polarizations show that the proposed PRC has good polarization and angle stabilities. Moreover, the general design procedure and method is presented. Finally, a circularly shaped PRC array using the proposed PRC element based on the MFSS design is fabricated and measured. The agreement between the simulated and measured results is excellent.
