Foi relatado que adicionando dois elementos dobrados, a antena gravata borboleta pode ser miniaturizada, mas a antena tem problema de degradação do VSWR. Neste artigo, os detalhes da degradação do VSWR são investigados e o mecanismo físico da degradação é esclarecido. A melhor posição para o elemento dobrado também é mostrada. Além disso, a antena de gravata borboleta é dobrada ao meio para obter maior redução de tamanho. Quando os dois elementos dobrados são adicionados à antena tipo gravata borboleta meio dobrada, a frequência de operação mais baixa diminui e a antena proposta pode ser mais reduzida do que a antena proposta anterior. O ganho é ligeiramente inferior ao do modelo anterior, no entanto, a área da antena é reduzida de 31%, que é a proporção da área da antena proposta anteriormente e da antena convencional, para 19%. A largura de banda de 92% é obtida para VSWR≤2.

Abstract: It has been reported that by adding two folded elements, bow-tie antenna can be miniaturized, but the antenna has VSWR degradation problem. In this paper, the details of the VSWR degradation are investigated and the physical mechanism of the degradation is clarified. The best position for folded element is also shown. Moreover, the bow-tie antenna is bent in half in order to realize more size reduction. When the two folded elements are added to the half bent bow-tie antenna, the lowest operation frequency goes down and the proposed antenna can be more downsized than the previous proposed antenna. The gain is slightly lower than that of the previous model, however, the antenna area is reduced from 31%, which is the antenna area ratio of privious proposed antenna and conventional bow-tie antenna, to 19%. The bandwidth of 92% is obtained for VSWR≤2.
