Definitions
- This invention relates to an antenna system and, more specifically, to an antenna system primarily for use in conjunction with base station in mobile communications systems.
- Mobile communication systems generally include a base station for receiving and transmitting electromagnetic radiations with the mobile terminal disposed within the coverage area of the base station for transmitting electromagnetic radiations to and receiving such radiations from the base station and where several such base stations are generally linked together through base station controllers (BSCs) and master station controllers (MSCs) to provide a seamless communication link between a mobile terminal and its calling party.
- BSCs base station controllers
- MSCs master station controllers
- the radiating element is fed by a ground based high power amplifier through a long cable, typically between 50 and 200 feet.
- a ground based high power amplifier typically between 50 and 200 feet.
- the placement of the power amplifiers within the base station also requires increased power from the amplifiers to overcome the insertion loss from the feed cable as well as the combiner.
- the combiner output is fed to a filter/low noise amplifier (LNA) combination through either a short transmission line (as in PCS systems for mast mounted LNAs) or through a long cable (as in cellular systems for base station integrated LNAs.
- LNA filter/low noise amplifier
- Dual redundant amplifiers are typically provided when mast mounted electronics are used to improve reliability at the expense of complexity.
- the effective noise increase contributed by the ohmic losses in the array combiner and feed cable are amplified by the low noise amplifier and thus contribute to the increase in the system noise figure.
- the distributed nature of the amplifiers also improves reliability since the system can be designed to be fully compliant even after failure of one or more of the receive or transmit amplifiers. Even when sufficient failures occur to reduce overall system performance, the performance degradation is graceful rather than catastrophic.
- Another advantage of distributed power amplifiers is that the amplifiers operate in a reduced thermal density environment, yielding enhanced reliability.
- the reduced thermal density results from the fact that the heat is distributed across the full area occupied by the antenna elements in the array rather than in a concentrated small area as in the case of unitary high power amplifiers used in the existing PCN base stations.
- FIGURE 3 is a diagram of an active antenna system architecture in accordance with a second embodiment of the present invention.
- FIGURE 1 there is shown a system utilizing the prior art PCN base station antenna architecture.
- FIGURE 1 is typical of the existing state of the art for PCS antenna systems. However, the discussion that follows applies to existing cellular systems as well.
- the system includes a transmit antenna system 1 and a receive antenna system 7.
- the transmit antenna system 1 includes a support 3 having thereon a plurality of radiating antenna elements 5 disposed in a straight line, the distance from the topmost element to the bottommost element being a few meters.

Abstract
Cette invention se rapporte à un système d'antenne actif qui possède plusieurs éléments d'antenne disposés en colonne, chacun de ces éléments ou chaque sous-ensemble d'éléments étant intégré à un amplificateur et à d'autres composants formant faisceau. Un amplificateur et un filtre séparés sont disposés à proximité immédiate et connectés à chacun des éléments d'antenne ou à un sous-ensemble d'éléments d'antenne et un combineur/diviseur séparé est connecté à chacun des amplificateurs. Les éléments d'antenne, l'amplificateur et le filtre sont disposés sur un support commun. Une station de base est connectée par les câbles d'alimentation, à distance de chacun des amplificateurs. Un premier groupe de ces éléments d'antenne ayant des amplificateurs basse puissance forme un système d'antenne émetteur et/ou un second groupe de ces éléments d'antenne actifs ayant des amplificateurs à faible bruit forme un système d'antenne récepteur. Un atténuateur variable et un circuit de déphasage variable peuvent être intégrés à chaque amplificateur et peuvent être utilisés pour la mise en forme du faisceau et le pointage électronique du faisceau. Pour la combinaison de diversité, on utilise des antennes actives séparées dans l'espace ou à diversité de polarisation. Pour une réalisation avec des antennes actives en diversité de polarisation, on utilise une colonne partagée ou deux colonnes à polarisation orthogonale adjacentes.
