Abstract

The leakage characteristics of a new millimeter‐wave omnidirectional circular rod antenna with multi‐dielectric gratings are analyzed by an improved perturbation method. The analysis yields an expression for the leakage constant in a closed form so that the design procedure of the antenna becomes very convenient. It is found that under conditions of the same dimension of the antenna, the multi‐layer grating antenna has more radiation efficiency than that of the single one. Its accuracy has been verified with the exact solution based on the mode matching method. © 2002 Wiley Periodicals, Inc.
