Abstract

Patente de Invenção: "ANTENA DE SUBSTRATO". Uma antena de substrato (400) que inclui uma ou mais trilhas condutoras (402) suportadas sobre um substrato dielétrico (404) possuindo uma espessura predeterminada. Dimensões apropriadas são selecionadas para os comprimentos e larguras das trilhas com base no comprimento de onda de interesse, elementos de conexão e espaço alocado. O substrato de suporte (404) é montado deslocado e de um modo geral perpendicular ao plano de terra (502) associado com o dispositivo com o qual a antena está sendo usada. A trilha está eletricamente conectada a uma base condutora (408) em uma extremidade. Uma alimentação de sinal (410) para a antena está acoplada à base condutora (408). A antena de substrato emprega uma estrutura muito delgada e compacta que propicia largura de banda apropriada. O pequeno tamanho da antena e uma grande variedade de formatos úteis permitem que a antena de substrato seja usada de forma muito eficiente como uma antena interna para dispositivos sem fio.Invention Patent: "SUBSTRATE ANTENNA". A substrate antenna (400) which includes one or more conductive tracks (402) supported on a dielectric substrate (404) having a predetermined thickness. Appropriate dimensions are selected for the lengths and widths of the tracks based on the wavelength of interest, connection elements and allocated space. The support substrate (404) is mounted offset and generally perpendicular to the ground plane (502) associated with the device with which the antenna is being used. The track is electrically connected to a conductive base (408) at one end. A signal supply (410) for the antenna is coupled to the conductive base (408). The substrate antenna employs a very thin and compact structure that provides appropriate bandwidth. The small size of the antenna and a wide variety of useful formats allow the substrate antenna to be used very efficiently as an internal antenna for wireless devices.
