Abstract

The characteristics of the omni-directional periodic circular dielectric rod leaky-wave antenna are analyzed by the improved perturbation method. The electromagnetic fields are described in terms of a radial transmission-line network

which brings considerable physical insight into the overall behavior of the periodic antenna. The analysis yields expression for the leakagd constant in a closed form

and the design procedure of the antenna is tremendously simplified. Comparisons between the approximate and [rigorous results

as well as the experimenal data

are made. It is found that the accuracy obtained from the perturbation analysis is adequate for practical design purposes.
