A meander-line polarizer covering the fullE-band (60-90 GHz)

Oblique Incidence Design of Meander-Line Polarizers for Dielectric Lens Antennas

“…Multilayered planar polarizers are convenient devices to transform the fields of a linearly polarized antenna into a circularly polarized wave at millimeter-wave frequencies [8]. A typical polarizer can be made of several stacked printed-meander-line sheets (the "grating" layer) separated by dielectric spacers.…”

Optimization Method of Wideband Multilayer Meander-Line Polarizer using Semi-Analytical approach and Application to 6-18GHz Polarizer including test with Horn Antenna

“…The principle of operation is to convert an incident wave into two equal and perpendicular components at ±45 degrees as summarized in [3]. The ML polarizer's layer is placed in the xyplane in such a way that the meander axes are all oriented at an angle Ψ = 45 degrees with respect to the incident electric field along the y-axis ( Figure 2).…”

“…A well-designed polarizer permits to change the antenna polarization and to propagate a different polarization without any significant variations in the pattern performance [2]. The Meander-Line (ML) polarizer is the most popular device used to change the Linear Polarized (LP) waves into the Circular Polarized (CP) ones [3]. It is a multilayer structure made of several printed ML sheets spaced by about onequarter wavelength apart.…”

Meta-Chirality: Fundamentals, Construction and Applications

“…The periodical unit cells give rise to giant interaction between the electromagnetic wave and the artificial structures. Besides, the interaction can be artificially controlled by tuning the type and size of the unit cells to achieve extraordinary electromagnetic functions, such as high-efficiency absorption [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ], broadband polarization conversion [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ], and optical imaging breaking through the diffraction limit [ 28 , 29 , 30 , 31 , 32 ]. Furthermore, the thickness and size of the fabricated devices would be greatly decreased, which provides an opportunity to manipulate the electromagnetic radiation in the sub-wavelength scale, and could be beneficial for highly integrated microwave or optical systems [ 33 ].…”
