Broadband low-profile antenna array with mechanoelectric scanning based on continuous transverse STUBS

The work is devoted to the development and study of a broadband low-profile antenna array with wide-angle mechanoelectric scanning based on continuous transverse stubs (CTS). In the proposed design, the antenna array is excited by a source of a plane quasi-TEM wave formed in a power divider based on binary dividers implemented on a U-shaped waveguide. Scanning is achieved by rotating the plane wave source relative to the CTS-array. The aperture efficiency of the antenna array was more than 60% when scanning in a sector of angles of $\pm$ 30$^\circ$ in a frequency band of more than 45% with VSWR of no more than 1.2. The proposed antenna does not have frequency scanning.
