Abstract

A new leaky-wave antenna taking advantage of substrate integrated waveguide technology has been introduced. This antenna has a butterfly-like configuration consisting of eight wings, i.e., eight parts. By this configuration, better gain and side-lobe level for lower elevation angles (12 °-45 °) are obtained while in the uniform design, these angles were scanned with poor radiation performances. Besides, an effective matching part for good impedance matching has been employed. The simulated data have been compared with measurement results and showed good consistency.
