Este artigo consiste nas duas novas tecnologias EMC que desenvolvemos em nosso laboratório. A primeira é a tecnologia de medição do campo magnético próximo de RF (Radiofrequência) e estimativa da corrente de RF na placa de circuito impresso (PCB) usando a pequena antena de loop com estrutura de PCB multicamadas desenvolvida por nosso laboratório. Apresento a aplicação de nossa pequena antena loop com sua estrutura física e a análise da distribuição do campo magnético próximo da placa de circuito impresso aplicando a análise Wavelet discreta. Podemos compreender detalhadamente o comportamento do circuito digital e também podemos tomar medidas para atender às especificações sobre a radiação eletromagnética do circuito digital de ordem mais alta de prioridade usando essas tecnologias. A segunda é a nossa proposta de nova tecnologia para reduzir a radiação eletromagnética do equipamento digital, observando a melhoria do desacoplamento no PCB. Confirmamos o efeito notável desta tecnologia ao redesenhar a placa-mãe do computador de pequeno porte.

Abstract: This paper is consisting of the two novel EMC technologies that we have been developed in our laboratory. The first is the technology for measuring the RF (Radio Frequency) nearby magnetic field and estimation of the RF current in the printed circuit board (PCB) by using the small loop antenna with multi-layer PCB structure developed by our laboratory. I introduce the application of our small loop antenna with its physical structure and the analysis of the nearby magnetic field distribution of the printed circuit board applying the discrete Wavelet analysis. We can understand the behavior of the digital circuit in detail, and we can also take measures to meet the specification about the electromagnetic radiation from the digital circuit from the higher order of priority by using these technologies. The second is our proposing novel technology for reducing the electromagnetic radiation from the digital equipment by taking notice of the improvement of the de-coupling in the PCB. We confirmed the remarkable effect of this technology by redesigning the motherboard of the small-sized computer.
