Definitions

  • Various aspects of the present disclosure relate to base station antennas, and, more particularly, to mechanical devices for controlling semi-independent tilt of diplexed antennas.
  • Mechanical tilt may be provided by angling the diplexed antenna physically downward, whereas electrical tilt may be provided by controlling phases of radiating signals of each radiating element so the main beam is moved downward. Mechanical and electrical tilt may be adjusted either individually, or in combination, utilizing remote control capabilities.
  • Network performance may be optimized if the tilt (e.g., electrical tilt) associated with each frequency band supported by an antenna is completely independently controlled.
  • this independence may require a large number of diplexers and other components, adding significant cost and complexity to the creation of a diplexed antenna.
  • Patent Document US 7 173 572 B1 is considered to be the closest prior art and relates to a dual band, dual pole, variable downtilt, 90 degree azimuth beamwidth antenna.
  • the antenna includes dipole elements forming both a PCS band and a cellular band antenna.
  • the PCS band antenna has two sections disposed each side of the cellular band antenna, the elements of each being positioned 90° with respect to the other.
  • a microstrip feed network formed upon a common PC board feeds the respective dipole elements, and has serpentine portions with a corresponding dielectric member slideable thereover to establish the phase of the associated dipole antennas and achieve a linear downtilt of the respective antenna array.
  • a slide rod adjustment assembly provides unitary movement of the dielectric members between two different slide rods. These dielectric members are secured with adhesive to the respective slide rods to achieve good dielectric control and no use of hardware.
  • the radiating dipole elements are capacitively coupled to each microstrip, and are also capacitively associated reflector element. One arm of the reflector element is offset at least 45 degrees with respect to the other arm to improve cross polarization.
  • a tilt adapter configured to facilitate a desired tilt of a first radio frequency (RF) band and a second RF band of an antenna.
  • the antenna supports two or more frequency bands, in which the vertical tilt of each of the supported frequency bands is separately controlled by a coarse level of phase shifting, but commonly controlled by a fine level of phase shifting.
  • the tilt adapter may comprise a first rod coupled to at least one first coarse phase shifter, a second rod coupled to at least one second coarse phase shifter; a cross linkage member operatively engaged to both the first and second rods; a first rack coupled to the cross linkage member; and a second rack coupled to the first rack, at least one first fine phase shifter, and at least one second fine phase shifter. Lateral movement of the first rod or the second rod causes lateral movement of the second rack.
  • FIG. 1 is a schematic diagram of an example of a diplexed antenna 100.
  • the diplexed antenna 100 includes first and second first level phase shifters 101, 103 coupled to inputs of respective diplexers 105, 107.
  • Each output of the respective diplexers 105, 107 may be coupled to sub-arrays of radiating elements 109, 111 resulting in a fixed tilt within the sub-arrays of the radiating elements 109, 111.
  • the diplexed antenna 100 exhibits simplicity and may be relatively inexpensive to implement. Unfortunately, the quality of radiation patterns produced by the diplexed antenna 100 may suffer due to some of the phase offsets being fixed.
  • each radiating element 201, 203, 205, 207 is coupled to a respective diplexer 209, 211, 213, 215, each of which is, in turn, coupled to outputs of each of phase shifters 217, 219.
  • the number of diplexers may double when employing dual polarization functionality.
  • Such diplexed antennas may increase in complexity and cost with greater lengths. For example, diplexed antennas having respective lengths of 1.4, 2.0, and 2.7 meters may require 10, 16, and 20 diplexers respectively, to produce high quality radiation patterns for each of the supported frequency bands.
  • diplexed antennas may be desirable for diplexed antennas to have an individually controllable tilt for each supported band. While completely individual controllable tilt may be desirable, there may be a significant correlation between (or among) the respective vertical tilt range of each supported band of the diplexed antenna, at least partly due to a frequency band tilt range's dependence on a mount height of the antenna supporting the frequency bands. More specifically, the higher above ground the antenna is mounted, the greater the tilt that may be required for acceptable operation.
  • aspects of the present disclosure may take advantage of the above discussed tilt correlation by being directed to a diplexed antenna for processing two or more frequency bands, where the vertical tilt of each of the supported frequency bands may be independently controlled by a coarse level of phase shifting, but commonly controlled by a fine level of phase shifting.
  • aspects of the present disclosure may achieve elevation patterns of a quality similar to that of the diplexed antenna 200 of FIG. 2 above, but at a low cost, light weight, and simplicity similar to that of the diplexed antenna 100 of FIG. 1 above.

  • input As used herein, "input”, “output”, and some other terms or phrases refer to the transmit signal path. However, because the structures described herein may be passive components, the networks and components also perform reciprocal operations in the receive signal path. Therefore, the use of "input”, “output”, and some other terms is for clarity only, and is not meant to imply that the diplexed antennas do not operate concurrently in both receive and transmit directions.
