Abstract

A kind of low sidelobe and high gain microstrip antenna array with 32×8 units operating in the X-band is designed, which achieves the gain of 28 dBi and the sidelobe level of-25 dB at 9.37 GHz. The Chebeshev distribution is used in designing the current distribution on the surface of this antenna, which achieves a width of main lobe of 5° in E-plane and a main lobe width of 10° in H-plane. The amplitude and phase of the feed current are extracted by using CST Microwave Studio®, the commercial simulation software, which indicate that the antenna achieves the Chebeshev current distribution. The sidelobe level calculated from this kind of current distribution is in good agreement with the simulation results, which proved the self-consistency of the simulation data.
