A nitidez da resposta roll-off dos filtros passa-banda é uma grande preocupação para os sistemas de comunicação sem fio. Filtros passa-banda com pólos de atenuação proporcionam um roll-off nítido. Este artigo investiga o desempenho de um filtro de linha comb de cerâmica com ressonadores de pólo de atenuação (APRs) e estuda os efeitos dos ressonadores de pólo de atenuação na resposta do filtro. As APRs apresentadas são versões melhoradas das anteriores e são aqui modeladas. Os resultados obtidos mostram que o comprimento dos APRs pode ser miniaturizado através da capacitância de carga. O volume resultante é de cerca de 400 mm3, que é muito pequeno em comparação com filtros do tipo coaxial com a mesma taxa de atenuação na banda de parada. Com a adição de ressonadores de pólo de atenuação, a atenuação da saia é bastante melhorada. Filtros passa-banda de largura de banda estreita com pólos de atenuação na banda de parada são projetados e testados. Dois exemplos projetados demonstram a flexibilidade do ressonador de pólo de atenuação na configuração do filtro. Os experimentos mostram boa concordância com os resultados da simulação.

Abstract: The sharpness of the roll-off response of bandpass filters is a major concern for wireless communication systems. Bandpass filters with attenuation poles provide sharp roll-off. This paper investigates the performance of a ceramic comb-line filter with attenuation pole resonators (APRs), and studies the effects of the attenuation pole resonators on the filter response. The presented APRs are improved versions of previous ones and they are modeled here. The obtained results show that the length of APRs can be miniaturized via the loading capacitance. The resultant volume is about 400 mm3, which is very small comparing to coaxial type filters with the same attenuation rate in the stopband. With attenuation pole resonators added, skirt attenuation is greatly improved. Narrow bandwidth bandpass filters with attenuation poles in the stopband are designed and tested. Two designed examples demonstrate the flexibility of the attenuation pole resonator in the filter configuration. Experiments show good agreement with simulation results.
