É proposta uma nova estrutura de antena planar de banda larga, combinando elementos monopolo com estruturas de bandgap eletromagnético (EBG). A antena possui uma estrutura simples de camada única e um padrão de feixe exclusivo. A antena é fabricada em uma superfície de um substrato dielétrico de camada única e a parte traseira do substrato é coberta com uma camada de metal. No centro do substrato, uma tira monopolo L invertida é fabricada e em ambos os lados deste monopolo, são colocadas células unitárias EBG. Ao ajustar o comprimento do monopolo e a frequência do bandgap EBG, o monopolo ressoa mesmo que exista uma camada de metal perto do radiador monopolo. Três tipos de EBG, unidimensional (1D), quadrado bidimensional (2D) e hexagonal 2D, são testados. Ao combinar a faixa monopolo com 2D-EBG hexagonal, a largura de banda da antena protótipo, cuja perda de retorno é inferior a 10 dB, é de 840 MHz na banda de 5 GHz. Para controlar os padrões de feixe da antena, elementos parasitas são colocados próximos ao radiador monopolo e aos EBGs. Esses elementos parasitas funcionam como diretores da antena quase Yagi-Uda e o ganho de radiação em ângulos de inclinação mais baixos é melhorado.

Abstract: New structure of broadband planar antenna, combining monopole elements with electromagnetic bandgap (EBG) structures, is proposed. The antenna has a simple single layer structure and unique beam pattern. Antenna is fabricated on a surface of a single layer dielectric substrate and back side of the substrate is covered with metal layer. At the center of the substrate, an inverted L monopole strip is fabricated and on both sides of this monopole, EBG unit cells are placed. By tuning monopole length and EBG bandgap frequency, the monopole resonates even if metal layer exists close to the monopole radiator. Three types of EBG, one dimensional (1D), square two dimensional (2D) and hexagonal 2D, are tested. By combining monopole strip with hexagonal 2D-EBG, the bandwidth of prototype antenna, whose return loss is less than 10 dB, is 840 MHz in 5 GHz band. To control beam patterns of antenna, parasitic elements are placed close to the monopole radiator and EBGs. These parasitic elements work as directors of quasi Yagi-Uda antenna and radiation gain at lower tilt angles is improved.
