Este artigo apresenta a melhoria das características de isolamento porta a porta de uma antena microstrip multi-ring de banda dupla e banda larga linearmente polarizada (MR-MSA) alimentada por duas sondas L. O MR-MSA de banda dupla e banda larga linearmente polarizado consiste em dois remendos de anel circulares e duas sondas L dispostas em um substrato dielétrico de múltiplas camadas. Usando um substrato espesso para a sonda L e organizando dois remendos de anel como elementos de radiação, a antena proposta opera características de banda larga e banda dupla. Além disso, ao organizar duas sondas L nas posições ortogonais, a antena proposta pode irradiar polarizações lineares duplas. Neste artigo, para melhorar as características de isolamento porta a porta do MR-MSA de banda dupla e banda larga linearmente polarizado, alimentado por duas sondas L, uma via conectada ao plano de terra no centro dos elementos de radiação é disposta . As larguras de banda fracionárias abaixo de -10dB de reflexão obtidas pela simulação do MR-MSA com a via foram 17.0% e 14.4%. Além disso, as características de isolamento simuladas foram superiores a 21.0dB e 17.0dB nas duas bandas. A melhoria das características de isolamento entre duas portas, bem como o desempenho de banda dupla e banda larga do MR-MSA proposto com a via foram confirmados pela simulação e pela medição.

Abstract: This paper presents improvement of port-to-port isolation characteristics of a linearly dual-polarized dual-band and wideband multi-ring microstrip antenna (MR-MSA) fed by two L-probes. The linearly dual-polarized dual-band and wideband MR-MSA consists of two circular ring patches and two L-probes arranged in a multi-layered dielectric substrate. By using a thick substrate for the L-probe and arranging two ring patches as radiation elements, the proposed antenna operates wideband and dual-band characteristics. Furthermore, by arranging two L-probes at the orthogonal positions, the proposed antenna can radiate dual linear polarizations. In this paper, for improving port-to-port isolation characteristics of the linearly dual-polarized dual-band and wideband MR-MSA fed by two L-probes, a via connected to the ground plane at the center of the radiation elements is arranged. The fractional bandwidths below -10dB reflection obtained by the simulation of the MR-MSA with the via were 17.0% and 14.4%. Furthermore, the simulated isolation characteristics were more than 21.0dB and 17.0dB in the two bands. Improvement of the isolation characteristics between two ports as well as the dual-band and wideband performance of the proposed MR-MSA with the via were confirmed by the simulation and the measurement.
