Abstract

"MéTODO E SISTEMA PARA PRODUZIR ESTADOS DE POLARIZAçãO DUAL COM LARGURAS DE FEIXE DE RF CONTROLADAS". Um sistema de antena pode gerar campos de radiação de RF tendo estados de polarização simultânea dual e tendo padrões de radiação substancialmente rotacionalmente simétricos. O sistema de antena gera padrões de radiação RF em que as larguras de feixe dos respectivos campos de RF para os respectivos elementos de radiação são substancialmente iguais e são relativamente grandes apesar do tamanho físico compacto do sistema de antena. O sistema de antena pode incluir um ou mais radiadores de reparo (patch) e um reparo não ressonante separado dos outros por um dielétrico de ar e por elementos espaçadores relativamente pequenos. Os radiadores de reparo e o reparo não ressonante podem ter formados pré-definidos para aumentar a discriminação de polarização. Os radiadores de reparo inferiores podem ser montados em uma placa de circuito impresso que pode incluir uma rede de alimentação RF e um plano terra que define uma pluralidade de sulcos simetricamente formatados. Os sulcos dentro do plano terra da placa de circuito impresso podem ser excitados por troncos que são parte da rede de alimentação da placa de circuito impresso. Os sulcos, por sua vez, podem estabelecer um modo magnético transversal de radiação RF em uma cavidade que é disposta adjacente ao plano terra da placa de circuito impresso e um plano terra do sistema de antena. A rede de alimentação da placa de circuito impressa pode ser alinhada com partes da cavidade tal que as partes da cavidade funcional como uma banheira de calor para absorver ou receber a energia térmica produzida pela rede de alimentação."METHOD AND SYSTEM FOR PRODUCING DUAL POLARIZATION STATES WITH CONTROLLED RF Beam WIDTHS". An antenna system can generate RF radiation fields having dual simultaneous polarization states and having substantially rotationally symmetrical radiation patterns. The antenna system generates RF radiation patterns where the beam widths of the respective RF fields for the respective radiation elements are substantially equal and are relatively large despite the compact physical size of the antenna system. The antenna system may include one or more patch radiators and a non-resonant repair separated from the others by an air dielectric and relatively small spacer elements. Repair radiators and non-resonant repair may be pre-formed to increase polarization discrimination. Lower repair radiators may be mounted on a printed circuit board which may include an RF power supply network and a ground plane defining a plurality of symmetrically shaped grooves. Grooves within the ground plane of the printed circuit board may be excited by trunks that are part of the printed circuit board power network. The grooves, in turn, can establish a transverse magnetic mode of RF radiation in a cavity that is disposed adjacent the ground plane of the printed circuit board and an earth plane of the antenna system. The printed circuit board power supply may be aligned with cavity parts such that the functional cavity parts such as a heat bath to absorb or receive the thermal energy produced by the power supply network.
