Abstract

"antena carregada dieletricamente e aparelho de radiocomunicação" trata-se de uma antena carregada dieletricamente do tipo "backfire" para operação a uma frequência maior que 200 mhz, compreendendo: um núcleo dielétrico eletricamente isolante de um material sólido tendo uma constante dielétrica relativa maior do que 5 e tendouma superfície externa incluindo partes de superfície distal e proximal direcionadas opostamente estendendo-se transversalmente de um eixo geométrico da antena e uma parte de superfície lateral estendendo-se entre as partes de superfície estendendo-se transversalmente, a superfície externa do núcleo definindo um volume interno, grande parte do qual é ocupada pelo material sólido do núcleo; uma estrutura de elemento de antena tridimensional incluindo pelo menos um par de elementos de antena condutores alongados dispostos na parte de superfície lateral do núcleo, ou adjacente a ela, e estendendo-se a partir da parte de superfície distal do núcleo em direção à parte de superfície proximal do núcleo; uma estrutura de alimentação na forma de uma placa laminada alongada estendendo-se axialmente compreendendo ao menos uma seção de linha de transmissão atuando como uma linha de alimentação que se estende através de uma passagem no núcleo a partir da parte de superfície distal do núcleo até a parte de superfície proximal do núcleo, e uma seção de conexão de antena na forma de uma extensão proximal formada integralmente da seção de linha de transmissão cuja largura, no plano da placa laminada, é maior do que a largura da passagem, e; uma seção de correlação de impedância ac´plando os elementos de antena à linha de alimentação."Dielectrically charged antenna and radio communication device" means a dielectrically charged "backfire" antenna for operation at a frequency greater than 200 mhz, comprising: an electrically insulating dielectric core of a solid material having a relative dielectric constant greater than which is an outer surface including oppositely directed distal and proximal surface portions extending transversely of a geometrical axis of the antenna and a lateral surface portion extending between the transversely extending surface portions, the outer surface of the core defining an internal volume, much of which is occupied by the solid core material; a three-dimensional antenna element structure including at least one pair of elongate conductive antenna elements disposed on or adjacent to the lateral surface portion of the core and extending from the distal surface portion of the core toward the proximal surface of the nucleus; a feed structure in the form of an axially extending elongate laminated plate comprising at least one transmission line section acting as a feed line extending through a passage in the core from the distal surface portion of the core to the proximal surface portion of the core, and an antenna connection section in the form of a proximal extension formed integrally of the transmission line section whose width in the plane of the laminated plate is greater than the width of the passage, and; an impedance correlation section connecting the antenna elements to the power line.
