Abstract

In this paper, a broadband flat sheet reflector antenna array with low-sidelobe is designed and analyzed. This antenna array is composed of 12 elements. By optimizing the configurations of the elements and the Power Dividers, a low-sidelobe is achieved in the band of 800~1350MHz. The measured results indicate that the VSWR of this antenna array is less 2, the gain is more than 15~17dBi, the sidelobe level is less than -20dB and the characteristic of patterns well in this band, and the comparative bandwidth is more than 51%. It is of great value in some special communication systems.
