Abstract：In order to realize the application of patch antenna in missile?borne terminal guidance,a new di-rectivity patch antenna based on the phase gradient is designed.This paper utilizes phase gradient meta?surface for changing the characteristics of electromagnetic wave propagation in direction,and designs a new patch antenna whose main lobes are deviated from normal of patch antenna at large angle.The antenna consists of seven H?shaped patches,and a desired phase gradient is obtained by optimizing the structure parameters.The results show that with the introduction of phase gradient,the main lobes of the antenna deviated from normal are about 45°in maximum gain direction while operating frequency is 9.6 GHz.
