Abstract

<B>ANTENA DE TRANSMISSãO POLARIZADA ORTOGONALMENTE E MéTODO DE TRANSMISSãO<D> Para resolver o problema de adicionar portadoras de RF suplementares a um sinal transmitido para atender o número crescente de assinantes, é utilizada uma configuração de antena com pares de antenas de transmissão polarizadas ortogonalmente. As antenas polarizadas ortogonalmente estão de preferência dispostas em uma relação substancialmente de +45°/ -45° e mantêm substancialmente centros co-faseados. Ao utilizar pares de componentes de antenas polarizadas ortogonalmente, o número de antenas necessárias para transmitir sinais de portadora pode ser reduzido à metade. Além disso, podem ser evitadas dimensões e limitações de espaço indesejadas sem uma substancial perda nos sinais de portadora de saída e sem substancial interferência de sinal.<B> ORTALLY POLARIZED POLARIZED TRANSMISSION ANTENNA AND TRANSMISSION METHOD <D> To solve the problem of adding additional RF carriers to a transmitted signal to meet the growing number of subscribers, an antenna configuration with polarized transmission antenna pairs is used orthogonally. The orthogonally polarized antennas are preferably arranged in a substantially + 45 ° / -45 ° ratio and substantially maintain co-phased centers. By using pairs of orthogonally polarized antenna components, the number of antennas required to transmit carrier signals can be halved. In addition, unwanted dimensions and space limitations can be avoided without substantial loss in outgoing carrier signals and without substantial signal interference.
