A novel dual‐polarization (DP) rectangular horn with equal elliptical beams for synthetic aperture radar application is proposed. The DP elliptical beams with same beam width are achieved by loading groove with coupling gap in the rectangular horn narrow side. The key parameters of the proposed horn are analyzed and a prototype operated at S band is fabricated and measured. Good agreements between simulated and measured results are obtained. What's more, an elliptical reflector antenna based on the proposed horn feed array is devised. Compared with the common rectangular horn, the reflector with the proposed horn owns better DP radiation performance.
