| Zusammenfassung: | The present invention provides a waveguide slot array antenna having an excitation slot arrangement radiating a signal corresponding to an operating frequency in a radiation plate. The waveguide slot array antenna comprises: a first auxiliary radiation plate installed on the main radiation plate and rotating a polarization plane of a signal radiated from the excitation slot arrangement of the main radiation plate; and a second auxiliary radiation plate installed on the first auxiliary radiation plate and distributing and radiating the signal, wherein the polarization plane of the signal has been rotated in the first auxiliary radiation plate. According to the present invention, a grating lobe is more effectively suppressed.
