N2 - In this paper, a method using genetic algorithm to suppress the grating lobe of a wideband planar array is presented. With the alteration of operating frequency point, the electrical size of distance between two adjacent elements will change thereupon. This approach achieves the suppression of grating lobe at high operating frequency point, whose highest sidelobe level is around -10 dB, with little influence to array's radiation characteristic of lower frequency point. For this approach's practicability, simple dipole antenna is adopted as the array's element to check out whether the approach keeps validity by simulation.
