摘要：

In this paper a planar leaky-wave antenna in a superstrate-like configuration is used to generate a cosecant-squared radiation pattern. As a difference with previous designs based on such configurations, the superstrate here is truncated. In this way an asymmetric illumination of the radiating aperture is achieved, thereby generating the required pattern. The antenna is fed by a waveguide open in the ground plane of the structure. A dispersion analysis is adopted for designing the antenna. Full-wave numerical results validate the proposed approach and structure. The proposed antenna may find application in mobile communication and radar systems.
