Este artigo propõe uma nova antena monopolo ramificada de banda quádrupla com filtro. A antena proposta possui uma configuração simples na qual elementos ramificados são adicionados a uma configuração básica composta por um mastro e fios dielétricos. A antena é caracterizada por desempenhos como correspondência de impedância de banda larga, estabilização de ganho e aprimoramento de ganho. As características de impedância de banda larga que satisfazem a relação de tensão inferior a 2 são obtidas excitando uma ressonância paralela na banda mais baixa e multirressonância nas bandas altas. O filtro que suprime os modos de ordem superior é usado para estabilização de ganho, de modo que ganhos médios acima de 5dBi sejam obtidos na quad-band. A antena tem um alto ganho de 11.1dBi porque os elementos ramificados funcionam como um conjunto de antenas end-fire na banda mais alta. Além disso, é esclarecido que uma frequência de operação é comutada usando um filtro passa-banda variável na banda mais baixa. Por último, um modelo em escala da antena é fabricado e medido, e então a eficácia da antena proposta é demonstrada.

Abstract: This paper proposes a novel quad-band branched monopole antenna with a filter. The proposed antenna has a simple configuration in which branch-elements are added to a basic configuration consisting of a mast and dielectric wires. The antenna is characterized by performances such as wideband impedance matching, gain stabilization, and gain enhancement. Wideband impedance characteristics satisfying the voltage standing ratio of less than 2 are obtained by exciting a parallel resonance at the lowest band and multi-resonance at high bands. The filter suppressing higher order modes is used for gain stabilization, so that averaged gains above 5dBi are obtained at the quad-band. The antenna has a high gain of 11.1dBi because the branch-elements work as an end-fire array antenna at the highest band. Furthermore, it is clarified that an operating frequency is switched by using a variable bandpass filter at the lowest band. Last, a scale model of the antenna is fabricated and measured, then the effectiveness of the proposed antenna is demonstrated.
