Abstract

The radiation characteristics of the double dielectric grating leaky-wave antenna are analyzed by the improved perturbation method. The results indicate that under the condition of the same radiation intensity, the double dielectric grating antenna has relatively smaller dimensions than that of the single one. It is undoubtly of great importance in the case that the limitation of the weight and volume of system is strictly required. The results obtained from this paper are compared with the exact solution based on the mode matching method. It is justified that the present perturbation procedure yields as highly results as the rigorous approach with extremely simplicity of the analysis and calculations.
