摘要：

In this paper, a broadband wide-angle leakywave antenna (LWA) with low sidelobe levels (SLL) is proposed. The antenna is composed of two parts: and electromagnetic bandgap (EBG) structures tiled on both sides of the antenna array. By controlling the coupling distances between the circular radiation patches and SSPP feeding line, the attenuation constant along the radiation aperture is specially designed in a tapered way to achieve low SLL. EBG structures are adopted to reduce the back-lobe levels. Measured results show that in radar detection and microwave imaging.
