- W1575366231 abstract "In this paper, two transmitarrays are designed, analyzed, and simulated for satellite applications. The first transmitarray is designed for dual linear polarization at a center frequency of 12 GHz. The second transmitarray is designed for two frequency bands: 17.15 GHz to 17.9 GHz for vertical polarization and 11.5 GHz to 12.4 GHz for horizontal polarization. The dual polarization is obtained by an independent adjustment of the dimensions of two orthogonal slots in the transmitarray unit cel. The design is carried out independently for each polarization. The transmitarray unit cell uses two dielectric substrate layers arranged to be one on each side of a conducting plane. On each substrate, one face has metallization containing the patches, and the other face has metallization containing the ground plane. The two patches are coupled by two cross slots of lengths L <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>v and L<sub>H</sub> in the ground plane and each patch is loaded with two cross slots of lengths Lv/2 and L<sub>H</sub>/2. The unit cell achieves 360° of phase agility with less than 3.8 dB of variation in the transmission magnitude in the tuning range. The transmitarray consisted of 17x17 elements with the unit cell size were set at 13 mm. A circular feed horn is located on the central normal to the transmitarray and the configuration looks like a lens antenna. Two separate feeding pins are used to excite the horn antenna for horizontal and vertical polarizations. The results are worked out using two basically different numerical techniques, the finite element method, FEM, and the finite integration technique, FIT. Good agreement was obtained.</sup>" @default.
