Outline of Final Research Achievements

The objective of this study is to develop a novel planar array antenna with a microstrip antenna fed by a rectangular waveguide. A waveguide slot array on a broad wall for linear polarization parallel to the axis always faces a problem of grating lobes. In order to overcome this problem, a microstrip antenna array fed by transverse slots on the broad wall of the rectangular waveguide is proposed. It is revealed that radiation power ratio of the array element can be controlled sufficiently and that the proposed array exhibits an excellent performance with suppressed grating lobes. The validity of the proposed planar array antenna is fully demonstrated.
