| description | In this paper, we designed a sliding waveguide array antenna that can be beam-steered via mechanical manipulation. This reduces the vulnerability of electronic beam-steering radars mounted on ships or aircraft to electromagnetic pulse (EMP) attacks. The design frequency was 9.375 GHz. First, the proposed antenna was designed to adjust the phase difference between the arrayed waveguide antennas by changing the length of the rectangular waveguide using a slide. Subsequently, a ridge structure with optimized curvature was attached to the aperture of the rectangular waveguide to obtain stable reflection coefficient characteristics. Finally, eight rectangular waveguide antennas and two dummy antennas were E-plane arrayed at intervals of 0.8λ (25.6 mm) to obtain a beam width of nearly 8°. A beam width of 8° was then obtained by adjusting the length of each waveguide. It was possible to orient the beam of the antenna in intervals of 8° using the phase difference of each antenna. The proposed mechanical beam steering technique can replace electronic beam steering for radar antennas, rendering the structures less vulnerable to EMP attacks. |
