“…Special attention was paid to concept of a fixed antenna in which small parts are moved. Many such concepts have been presented in [3][4][5][6], as candidates for millimeter wave scanning antennas and in [7][8][9] for satellite communications. The Eagle Scanner of World War II was possibly the first electromechanically beam scanning antenna and included displacement of the narrow wall of a rectangular waveguide [10] in order to introduce phase shifting in a series-fed linear array.…”

The design, simulation and measurement of a beam steerable slotted waveguide antenna operating in X band are presented. The proposed beam steerable antenna consists of a standard rectangular waveguide (RWG) section with longitudinal slots in the broad wall. The beam steering in this configuration is achieved by rotating two dielectric slabs inside the waveguide and consequently changing the phase of the slots excitations. In order to confirm the usefulness of this concept, a non-resonant 20-slot waveguide array antenna with an element spacing of d = 0.58λ0 has been designed, built and measured. A 14º beam scanning from near broadside (θ = 4º) toward end-fire (θ = 18º) direction is observed. The gain varies from 18.33 dB to 19.11 dB which corresponds to the radiation efficiencies between 95% and 79%. The side-lobe level is -14 dB at the design frequency of 9.35 GHz. The simulated co-polarized realized gain closely matches the fabricated prototype patterns.

“…But the scanning speed is slow and continuous scanning is possible. The feed of the Ku‐band CTS array antenna is a waveguide slot array antenna with a narrow matching bandwidth, and continuous beam scanning is performed by rotating the slot array of the waveguide. The CTS array antenna feed designed in this letter is a H‐plane horn antenna based on SIW technology.…”

“…Mauro Ettorre et al designed the Ka‐band wide‐band all‐metal CTS array antenna, achieving the performance of high gain, wide band, low sidelobe, and H‐plane beam scanning through a translational horn feed, but the fabrication process is complicated. Xianlong Lu et al designed the Ku‐band CTS array antenna, high gain, and H‐plane beam scanning performance is accomplished through the rotary feed (low sidelobe waveguide slot array). However, the relative bandwidth of the antenna array is only 3.5%.…”

A hybrid structure continuous transverse stub (CTS) array antenna for Ka‐band is demonstrated in this article. The array comprises 16 radiating slots, the H‐plane horn antenna based on the substrate integrated waveguide (SIW) and is fed by a corporate‐feed network in parallel plate waveguide (PPW) technology. The scanning angle of the main beam of the antenna reaches ±40° through switching the horn feed. Measurement shows that the CTS antenna has an relative bandwidth of 17.2% from 26.5 to 31.5 GHz for the standards of |S11| < −10 dB. At the center frequency of 29 GHz, the antenna gain of 28 dBi is obtained, the H‐plane sidelobe level (SLL) is −28.5 dB, and the radiation efficiency reaches 90%. The measurements are in very good agreement with full‐wave simulation results. The proposed design is suitable for Satcom Ka‐band terminals in moving platforms, for example, ships and planes.

“…Therefore, the operating bandwidth is relatively narrow. The operating bandwidth of this array is narrower than the designs of series-fed nonresonant CTS traveling wave array [9], [12] and corporate-fed CTS array [8], [10]. However, the proposed array has a similar bandwidth to the design of series-fed CTS standing wave array in [19].…”

“…By using the substrate-integrated waveguide (SIW) technology, a flat frequency-scanned antenna with the scanning range of −16.8°-55.2°was designed in [9]. In [10], a CTS array fed by the ridged waveguide slot array had the scanning range of ±30°by rotating the whole feed structure. However, all aforementioned arrays operated on the linear polarization and could only achieve 1-D beam scanning.…”
