Abstract: This letter presents a continuous transverse stub (CTS) array antenna with high aperture efficiency, low sidelobes, and cross-polarization characteristics over an E -band. The antenna consists of a full-corporate-feed 32-slot CTS array and a 45° linear polarizer. A multiple-aperture excited parallel-plate waveguide structure works as a linear source generator to generate the quasi-TEM wave with a uniform amplitude distribution over the whole operating band from 71 to 86 GHz. The 45° linear polarizer contains two layers of slots, shifting the linear polarization from the principal E -plane ( φ = 90°) to the intended E -plane ( φ = 135°). The array antenna achieves the low cross polarization and sidelobe level (SLL) while maintaining high aperture efficiency. Measurement results show that the antenna has an aperture efficiency of over 74% with the peak gains of better than 37.9 dBi over the whole E -band, while the far-field SLLs in the intended E - and H -planes approach the ETSI class IV envelope standard.

TL;DR: In this article, a dual-polarized aperture-coupled filtering antenna with embedded filtering circuits is presented, which is excited by two orthogonal microstrip feedlines to achieve dual polarizations.

TL;DR: A series of Al-C-N thin films with different Al contents were deposited on Si (100) substrates by closed field unbalanced reactive magnetron sputtering in the mixture of argon and nitrogen gases as discussed by the authors.

TL;DR: In this paper, air-filled patch antennas for millimeter-wave (mm-wave) applications are demonstrated using silicon-based micromachining techniques, which are fed by rectangular coaxial lines and made of five gold plated layers bonded together.

TL;DR: In this paper, a Ka-band 4×4 Butler matrix feeding a 4-element linear antenna array has been presented, which is based on a rectangular coaxial structure, constructed using five layers of gold coated micromachined silicon slices.
