Novel analysis scheme to analyze multilayer dielectric microstrip antennas

An efficient technique utilizing the advantages of the conformal mapping technique and the cavity model has been proposed in this paper to analyze easily and effectively, the multilayer stacked microstrip antenna structures. The proposed method is generalized to be suitable for analyzing such microstrip antennas of various geometries, namely, the rectangular, circular disc, annular ring and triangular patches. The closed form expressions for the resonant frequency, for any mode of operation, involve simple calculations yielding results which agree well with the experimental values. This unique method solves the long-standing problem of analyzing multilayer stacked microstrip antennas of various geometries with ease,.
