Neste artigo, um arranjo linear de 4 antenas de fenda tipo gravata borboleta em forma de folha é proposto para uso em bandas de ondas quase milimétricas. O conjunto de antenas de slot foi projetado para operar na banda de frequência de 28 GHz. A antena tipo gravata borboleta em forma de folha é um tipo de antena autocomplementar de baixo perfil e baixo custo de fabricação. A estrutura da antena proposta oferece melhorias no padrão de radiação, ganho e largura de banda de impedância de -10dB. Através deste papel, o padrão de radiação, o ganho real e a largura de banda de impedância de -10dB são avaliados pela simulação de domínio de tempo diferente finito (FDTD). As características da antena são analisadas na faixa de frequência de 27 GHz a 29 GHz. Para melhorar as características da antena, como ganho real e largura de banda de impedância de -10dB, uma camada de superstrato dielétrico com permissividade relativa de 10.2 é colocada no topo do plano de terra do conjunto de antenas de slot. Três estruturas de antena são apresentadas e comparadas. Com duas camadas de superstrato dielétrico no topo do plano de terra da antena, os resultados da análise mostram que a largura de banda de impedância de -10dB ocupa a faixa de frequência de 27.17 GHz a 28.39 GHz. Portanto, a largura de banda da impedância operacional é 1.22 GHz. O ganho real máximo do conjunto de antenas de slot com duas camadas de superstrato dielétrico é de 20.49dBi e a largura de banda de ganho de -3dB ocupa a faixa de frequência de 27.02 GHz a 28.57 GHz. Para validar os resultados da análise, é fabricado um protótipo do conjunto de antenas slot projetado. As características do conjunto de antenas de slot são medidas e comparadas com os resultados da análise.

Abstract: In this paper, a linear array of 4 leaf-shaped bowtie slot antennas is proposed for use in quasi-millimeter wave band. The slot antennas array is designed to operate at 28GHz frequency band. The leaf-shaped bowtie slot antenna is a type of self-complementary antenna with low profile and low cost of fabrication. The proposed antenna structure offers improvement in radiation pattern, gain, and -10dB impedance bandwidth. Through out of this paper radiation pattern, actual gain, and -10dB impedance bandwidth are evaluated by Finite Different Time Domain (FDTD) simulation. Antenna characteristics are analyzed in the frequency range of 27GHz to 29GHz. To improve antenna characteristics such as actual gain and -10dB impedance bandwidth, a dielectric superstrate layer with relative permittivity of 10.2 is placed on top of ground plane of the slot antennas array. Three antenna structures are introduced and compared. With two layers of dielectric superstrate on top of the antennas ground plane, analysis results show that -10dB impedance bandwidth occupies the frequency range of 27.17GHz to 28.39GHz. Therefore, the operational impedance bandwidth is 1.22GHz. Maximum actual gain of the slot antennas array with two dielectric superstrate layers is 20.49dBi and -3dB gain bandwidth occupies the frequency range of 27.02GHz to 28.57GHz. To validate the analysis results, prototype of the designed slot antennas array is fabricated. Characteristics of the slot antennas array are measured and compared with the analysis results.
