中文摘要	In this letter, we propose a high gain rectangular waveguide board wall slot array antenna, which is integrated with one dimensional subwavelength periodic corrugated grooves and artificially soft surface structure. The corresponding far field radiation characteristics are investigated. The simulation results show that the gain of planar 2 × 8 slot array antenna with the introduction of corrugated grooves structure is increased to 26.1 dB, and half power beamwidth in the E plane is considerably reduced. Compared with the subwavelength periodic grooves slits array antenna proposed by Huang et al.[Appl. Phys. Lett. 91, 143512 (2007)], the side and back lobe level of this antenna are also significantly reduced by 6 dB and 10 dB, respectively. The physical mechanism for radiation-pattern improvement has been well explained by the modulation of surface wave, the reradiation of surface energy, and suppression of surplus surface wave at the grounded edge.
