Definitions

  • the present invention is generally directed to a manner by which to transduce signal energy at a radio device, such as a portable mobile station. More particularly, the present invention relates to an antenna, and an associated methodology, for the radio device.
  • the antenna is of dimensions permitting its positioning within, or carriage together with, a hand-carriable mobile station while providing operability over a wide range of frequencies.
  • the antenna is formed of a wire antenna (monopole) and a set of patches that are configured together in a tri-dimensional arrangement. The spatial requirements of the antenna are reduced by folding one of the patches into folded portions.
  • the antenna is operable with a multi-mode radio device that operates at multiple, spaced frequency bands.
  • a cellular, or cellular-like communication system is an exemplary mobile radio communication system whose availability is widespread throughout significant portions of the populated areas of the world.
  • a cellular communication system is constructed generally to be in conformity with operational requirements set forth in an operating specification promulgated by a standards-setting body.
  • the operating specification defines a radio air interface extending between communication stations, i.e., the network infrastructure and a mobile station, operable in the communication system.
  • Regulatory bodies allocate portions of the electromagnetic spectrum. Different allocations are made for different types of systems, and different regulatory bodies regulate the use of the electromagnetic spectrum in different jurisdictions.
  • operating standards associated with different communication systems define operating parameters including parameters associated with the frequencies upon which the radio air interface is defined.
  • a mobile station While early implementations of mobile stations used to communicate in a cellular communication system were relatively bulky and heavy, advancements in integrated-circuit processing, and communication technologies have permitted the miniaturization of newer implementations of mobile stations. Mobile stations are now regularly of dimensions permitting their hand-carriage. And, increasingly, mobile stations are constructed to be operable in conformity with the operating requirements of more than one operating standard. Such a mobile station, referred to as a multi-mode mobile station, is capable of operation pursuant to a communication service by way of any communication system with which the multi-mode mobile station is operable.
  • Miniaturization of a mobile station provided as a result of the technological advancements noted-above has permitted the circuitry required for multi-mode mobile station to be housed in a housing of small dimension.
  • Multi-mode mobile stations are, for example, sometimes of configurations permitting their carriage in a shirt pocket of a user. Miniaturization is provided, not only by reducing the physical dimensions of the circuit paths of the receive and transmit chains of the circuitry of the mobile station, but also through sharing of circuit components between circuit paths used for communications pursuant to the different communication systems.
  • An antenna element is generally most effective in transducing signal energy when the transducer is of dimensions related to the wavelength of the signal energy that is to be transduced. For instance, antenna lengths corresponding to, or multiples of, one-quarter wavelengths of the signal energy that is to be transduced exhibit good antenna characteristics.
  • the mobile station forms a multi-mode mobile station that operates at different frequency bands, different sizes of antennas are needed to transduce the signal energy of the different frequencies and wavelengths.
  • a PIFA Planar Inverted-F Antenna
  • a PIFA is sometimes utilized to transduce signal energy at a mobile station.
  • a PIFA is of compact size and is of a low profile while providing for transducing of signal energy at more than one frequency band.
  • a problem typically exhibited with a PIFA is that a PIFA generally exhibits pass bands of narrow bandwidths.
  • a bandwidth of a PIFA is enhanced by configuring the PIFA together with a parasitic element. Such use of a parasitic element, however, increases the dimensions of the antenna.
  • the branches sometimes introduce EMC and EMI that interferes with antenna operation.
  • multiband monopole antennas are disclosed in US 2003/0001781 and US 2002/0101382 .
  • An improved antenna structure of small dimensions, and operable to transduce signal energy at multiple, disparate frequency bands is therefore needed.
  • a compact multiband monopole antenna has been realized by a configuration set out in apparatus claim 1 and method claim 13.
  • Figure 1 illustrates a functional block diagram of a radio communication system in which an embodiment of the present invention is operable.
  • Figure 2 illustrates a two-dimensional representation of the configuration of the antenna of an embodiment of the present invention.
  • Figures 3-5 illustrate various perspective representations of the antenna shown in Figure 2 , here in which the antenna is configured with folds formed of a wire (monopole) loaded with patches about a dielectric substrate.
  • Figure 6 illustrates a representation of an exemplary return loss, plotted as a function of frequency, of an exemplary antenna of an embodiment of the present invention.
  • Figures 7 and 8 represent exemplary radiation patterns exhibited by the antenna of an embodiment of the present invention at two separate frequencies, at 908 MHz and 1.84 GHz, respectively.

  • Signal energy generated at the mobile station circuitry is provided to the antenna at the feed point connection, and signal energy transduced into electrical form at the antenna is provided to the transceiver circuitry at the feed point connection.
  • a first patch of the antenna forms a first main matching element, and is, e.g., rectangular-shaped, forming a rectangular-shaped patch, extending from, and contiguous and integral with, the monopole.
  • the first patch improves matching to provide for antenna resonance at a first frequency band, depending upon the size of the patch and its location of connection to the monopole.
  • a second antenna patch forms a second matching element proximate to the feed point connection and extending from, and contiguous and integral with, said monopole.
