A closed form expression of the effective radius for the used structure is proposed. The obtained numerical results are compared with published measurements and good agreement is noticedenMicrostrip patch antennasParasitic stratified directorResonance frequenciesInput impedanceTransmission linesFinite coupled linesApplication of the FCEL method to a microstrip disk antenna with a parasitic directorArticle
