Previous issue date: 2013-07-26 / The planar circuits are structures that increasingly attracting the attention of researchers, due the good performance and capacity to integrate with other devices, in the prototyping of systems for transmitting and receiving signals in the microwave range. In this context, the study and development of new techniques for analysis of these devices have significantly contributed in the design of structures with excellent performance and high reliability. In this work, the full-wave method based on the concept of electromagnetic waves and the principle of reflection and transmission of waves at an interface, Wave Concept Iterative Procedure (WCIP), or iterative method of waves is described as a tool with high precision study microwave planar circuits. The proposed method is applied to the characterization of planar filters, microstrip antennas and frequency selective surfaces. Prototype devices were built and the experimental results confirmed the proposed mathematical model. The results were also compared with simulated results by Ansoft HFSS, observing a good agreement between them. / Os circuitos planares s?o estruturas que atraem cada vez mais a aten??o dos pesquisadores, pelo bom desempenho e pela capacidade de integra??o com outros dispositivos, na prototipagem de sistemas de transmiss?o e recep??o de sinais na faixa de micro-ondas. Neste contexto, o estudo e o desenvolvimento de novas t?cnicas de an?lise desses dispositivos t?m contribu?do de forma significativa na concep??o de estruturas com desempenhos excelentes e alto grau de confiabilidade. Neste trabalho, o m?todo de onda completa baseado no conceito de ondas eletromagn?ticas e no princ?pio da reflex?o e transmiss?o de ondas em uma interface, Wave Concept Iterative Procedure (WCIP), ou m?todo iterativo das ondas ? descrito como uma ferramenta com alto grau de precis?o no estudo de circuitos planares de micro-ondas. O m?todo proposto ? aplicado na caracteriza??o de filtros planares, antenas de microfita e superf?cies seletivas de frequ?ncia. Prot?tipos dos dispositivos foram constru?dos e os resultados experimentais comprovaram o modelo matem?tico proposto. Os resultados obtidos tamb?m foram comparados com os resultados simulados pelo Ansoft HFSS, tendo sido observada uma boa concord?ncia entre eles
