摘要

In this paper a Waveguide Slot Antenna working in X-Band (9.410-9.495 GHz) is presented. In the proposed configuration, a Taylor distribution in the slot excitation voltages and the insertion of a metallic shield allow to obtain a very low side lobe level and a significant reduction of radiating back lobe. The design has been developed using CST MICROWAVE STUDIO, a general purpose and specialist tool for the 3D electromagnetic simulation of microwave high frequency components.
