| Abstract(in English) | Microstrip comb line array antennas which possess low sidelobe and low feeding line loss are developed in the millimeter-wave band. Extremely low radiation elements and high accuracy of its radiation control are required in the design of Taylor distribution for low sidelobe such as lower than -30 dB. Radiation from the array elements has been controlled only by modification of the element width in the conventional comb line array antennas. However, it is difficult to realize small radiation from the element in the millimeter-wave band since the width of the element is limited more than 0.1 mm in etching process. We propose the way to extend the design freedom of radiation control of the array element in this paper. Radiation from the element depends on the ratio between the widths of transmission line and radiating element. Radiation from the element is reduced by using wide feeding line as well as narrow element. The linear array antenna with 27 radiating elements is developed and low sidelobe of -23.6 dB is observed in the experiments at the design frequency of 76.5 GHz. |
