Leaky-wave antenna

Abstract

A leaky-wave antenna includes a sheet arrangement having first, second and third metalized sheets that are arranged on top of and in parallel with one another and are separated by two di-electric layers, the first metalized sheet having a first two-dimensionally periodic metalization structure, the second metalized sheet having a second two-dimensionally periodic metalization structure, and the third metalized sheet having a continuous metalization area, and an excitation structure above the first metalized sheet for exciting a leaky-wave mode in the sheet arrangement at a working frequency f0 of the leaky-wave antenna, wherein the sheet arrangement exhibits a shape of a regular n-gon with N≧8 (N ∈ Z) or a circular shape as the edge boundary.
