Definitions

  • the present invention relates generally to an antenna construction for a mobile station, or other radio device, operable over multiple frequency bands. More particularly, the present invention relates to antenna apparatus, and an associated methodology, forming a hybrid strip antenna of a multi-mode mobile station, or other radio device, operable, e.g., at the 800/900/1800/1900 MHz frequency bands.
  • the antenna includes radiation elements comprising a loop strip including a meander line as a portion and an L-shaped strip, both disposed upon a substrate and configured to resonate at frequencies corresponding to the frequency bands at which the radio device is operable.
  • the antenna is of compact dimensions and exhibits stable frequency band characteristics and radiation patterns.
  • Radio communication systems For many, availability and use of mobile radio communication systems through which to communicate are necessary aspects of daily life.
  • Cellular, and cellularlike, communication systems are exemplary radio communication systems whose infrastructures have been widely deployed and regularly utilized.
  • Successive generations of cellular communication systems have been developed, the operating parameters and protocols of which are set forth in standards promulgated by standard-setting bodies. And, successive generations of network apparatus have been deployed, each operable in conformity with an associated operating standard.
  • multi-mode mobile stations have been developed that provide the mobile station with communication capability in more than one, i.e., multiple, communication systems.
  • such multi-mode mobile stations automatically select the manner by which the mobile station is to be operable, responsive to the detected network infrastructure in whose coverage area that the mobile station is positioned. If positioned in the coverage area of the network infrastructures of more than one type of communication system with which the mobile station is capable of communicating, selection is made pursuant to a preference scheme, or manually.
  • the mobile station contains circuitry and circuit elements permitting its operation to communicate pursuant to each of the communication systems.
  • a multi-mode mobile station is formed of separate circuitry, separately operable to communicate pursuant to the different operating standards.
  • parts of the separate circuit paths are constructed to be intertwined, or otherwise shared. By sharing circuit elements, the circuitry size and part count is reduced, resulting in cost and size savings.
  • antenna transducer element shares with the different circuit paths, however, presents unique challenges.
  • the required size of an antenna transducer element is, in part, dependent upon the frequencies of the signal energy that is to be transduced by the transducer element.
  • antenna transducer design becomes increasingly difficult, particularly in multi-mode mobile stations when the different modes operate at different frequencies.

  • Such antenna structures generally exhibit narrow bandwidths.
  • the structure of the PIFA is sometimes combined together with a parasitic element, or a multi-layered, three-dimensional structure.
  • Such additions however increase the volumetric dimensions of the antenna.
  • tuning the antenna becomes difficult due to the additional resonant branches. And, the branches sometimes introduce EMC and EMI that interfere with transduction of signal energy.
  • EP 1,739,788 A entitled “Mobile wireless communications device comprising multi-frequency band antenna and fabrication method” discloses a multi-frequency band antenna that includes a main loop conductor that has a gap and also includes a plurality of branch conductors extending outwardly of the main loop conductor. One branch conductor that extends through the gap into the area enclosed by the main loop conductor widens the antenna bandwidth at high frequencies.

  • the meander line is formed, for instance, along one of the peripheries of the substrate at which the loop is formed.
  • the meander line is of a length that is resonant at a second frequency band.
  • the second frequency band at which the meander line is resonant is determined by its length.
  • the meander line portion of the loop is caused to resonate at a frequency band corresponding to a frequency band of operation of the multi-mode mobile station.
  • the meander line is formed, e.g., by interdigitation of nonconductive segments, i.e., digits, into a rectangular swath of conductive material forming a portion of the loop formed about the periphery of the substrate.
  • the length of the meander line is increased by increasing the interdigitation of the nonconductive segments or digits.
  • An appropriate resonant frequency is made by use of a correspondingly appropriate amount of interdigitation.
  • the loop formed about the periphery of the substrate, and including a meander line as a portion thereof, thereby defines a set of resonant frequency bands, the first of which is defined by the entire length of the loop including the length of the meander line, and a second of which is defined by the length of the meander line.

  • the L-shaped strip resonates at a resonant frequency band.
  • the resonant frequency band at which the L-shaped strip is resonant is dependent upon the length of the strip. Through appropriate selection of the length of the strip, the resonant frequency band at which the strip resonates corresponds to a frequency band of operation of the mobile station to which the antenna is coupled.
  • the antenna is used in a multi-band, cellular mobile station operable in the 800/900/1800/1900 MHz frequency bands.

  • the length of the peripheral loop is determinative of a first resonant frequency at which the antenna resonates. Through appropriate selection of the length of the peripheral loop, the first resonant frequency is thereby formed.
  • the meander line 66 defines a meander-line length that is controlled by the number of, and dimensions of, non-conductive interdigitation fingers 68.
