Abstract
Una disposición de antenas comprende una pluralidad de unidades de antenas construidas y operadas independientemente, sobre la cual está montada unapluralidad de pares de antenas de transmisión y recepción. Esto proporciona un elemento para que ladisposición de antenas esté dispuesta para proveercobertura radial substancialmente hemisférica. Ajustando la fase de cada versión de una senal de radio a ser transmitida o recibida, la senal puede serformada dentro de un haz, de acuerdo a unatécnica conocida de formación de haces direccionales, proporcionando ganancia direccional a la disposición deantenas. Asimismo, utilizando una pluralidad de pares de antenas de transmisión y recepción se reduce la energía transmitida por cada antena de transmisiónsola a un nivel que permite que un acoplador de línea derivada sea suficiente para polarizar ortogonalmente las senales de radio transmitidas y recibidas,haciendo innecesario el requerimiento de un filtro duplexor para operacióndúplex.
