| Abstract(in English) | Low sidelobe slotted waveguide antenna is designed. In the design of low sidelobe slotted waveguide array antenna with traveling wave excitation, wide range of radiation control from slot is required since difference is large between assigned slot-couplings around the input port and at the end of the waveguide. We have already developed a slotted waveguide planar array antenna composed of post-loaded slots and feeding circuit of post-loaded T-junctions. In order to confirm the effect of these components, we design the antenna with sidelobe lower than -30dB as a target in this paper. As a result of the measurement, sidelobe levels were -21.1dB in the plane parallel to the radiating waveguide and -20.9dB in the plane parallel to the feeding waveguide. These levels are quite larger than the design. It is because the design was not perfect. However, as compared with the antennas of the conventional design, low sidelobe characteristics are confirmed as an effect of the proposed structures. Moreover, it was observed that the manufacturing error for width of feeding waveguide causes degradation of the radiation pattern. The relation between the radiation pattern and the manufacturing error were also evaluated quantitatively in this paper. |
