Abstract
Slotted waveguide array antenna with no grating lobes is designed and performance is evaluated by simulation. Grating lobes are suppressed by shortening the slot spacing or the effective guided wavelength in the waveguide by using metamaterial technique. Effect to suppress the grating lobe is confirmed by simulation of radiation pattern.
