摘要：

An X-band, broadband substrate-integrated waveguide slot antenna is presented in this article. It consists of a substrate layer and two metal layers. The ellipses lot on the top metal layer radiates an electromagnetic wave. The coplanar waveguide structure with a butterfly-shaped slot on the bottom metal layer is used to feed to the substrate-integrated waveguide. The butterfly-shaped slot, the coplanar feed line, and the ellipse slot produce three resonant frequencies that can be combined by adjusting parameters; the bandwidth can then be broadened. The experiment results show that the center frequency of the realized antennais 9.81GHz, the absolute bandwidth is 880 MHz, and the relative bandwidth is 8.9%. Compared with the results for normal substrate-integrated waveguide slot antennas, the relative bandwidth is improved about 5%
