Analysis of Circular Slots Leaky-Wave Antenna in Cylindrical Waveguide by Wave Concept Iterative Procedure

摘要

This paper presents the analysis of circular slots leaky-wave antenna by using an iterative method based on the wave concept. The classic method has been reformulated in cylindrical coordinates in order to be adequate for the analysis of the leaky-wave antenna with fast convergence. The proposed leaky-wave antenna can be used to replace a micro-strip patch array. Numerical results are presented to illustrate the advantages of the proposed structure. A good agreement between the new wave concept iterative procedure (WCIP) method results and published data is obtained.
