| Abstract(in English) | A longitudinal linear slot array arranged at a spacing of one guided wavelength on a narrow wall of the rectangular waveguide has a problem of radiation of grating lobes. This paper presents a novel microstrip antenna array fed by longitudinal slots on a narrow wall of the rectangular waveguide with polarization perpendicular to the axis. A dual-ring microstrip antenna with a circumference of 5 wavelengths excited by the longitudinal slot on the narrow wall of the waveguide with a dielectric substrate is used as an element of the proposed array. In order to validate the proposed array configuration, an eight-element array with travelling wave excitation is designed at 11.2 GHz and good radiation patterns with suppressed grating lobes are confirmed by experiment. |
