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.
