| Abstract: |
| The principle of microstrip reflectarray antenna is introduced.The patch size,the distance between the elements,phase-delay line,the thickness of dielectric substrate,the error analysis and simulation are discussed respectively.According to analysis,a design method for low sidelobe microstrip reflectarray antenna is proposed.The test result shows that the reflectarray antenna is easily folded and portable,and its performace is close to that of paraboloid antenna. |
| Key words: microstrip antenna,reflectarray,phase-delay line,low sidelobe |
