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.
