A broadband cylindrical‐rectangular microstrip antenna using two parasitic patches gap coupled to its radiating edges is studied by using a full‐wave analysis and a Galerkin's moment‐method calculation. Results indicate that, with parasitic patches, an antenna bandwidth greater than two times that of a single cylindrical‐rectangular patch antenna can be obtained. Details of the numerical results for different curvature radii and gap spacings are presented. © 1994 John Wiley & Sons, Inc.
