Definitions

  • the present invention relates to the field of communications devices, and, more particularly, to mobile wireless communications devices and related methods.
  • Cellular communications systems continue to grow in popularity and have become an integral part of both personal and business communications.
  • Cellular telephones allow users to place and receive voice calls most anywhere they travel.
  • cellular telephone technology has increased, so too has the functionality of cellular devices.
  • PDA personal digital assistant
  • multi-function devices may also allow users to wirelessly send and receive electronic mail (email) messages and access the Internet via a cellular network and/or a wireless local area network (WLAN), for example.
  • WLAN wireless local area network
  • Flip phones typically have an upper housing with a display and speaker, and a lower housing or flap which carries the microphone.
  • the keypad on such phones may be on either the upper housing or the lower housing, depending upon the particular model.
  • the lower flap is connected to the upper housing by a hinge so that when not in use the upper and lower housings can be folded together to be more compact.
  • the phone has two antennas, a first one of which is mounted on the lower flap and includes a ground plane and an active monopole fed by a coaxial feed from electronic circuitry inside the phone.
  • the flap is pivotally connected to the main or upper section of the housing, and is folded against the main section when not in use.
  • Another similar antenna is fitted in the main section, and both antennas are connected to transceiver circuitry in the phone.
  • the antennas are designed to introduce deliberate mismatch to provide an effective switching system between the antennas without the need for separate circuit elements.
  • the antenna configuration of a cellular telephone may also significantly effect the overall size or footprint of the phone.
  • Cellular telephones typically have antenna structures that support communications in multiple operating frequency bands.
  • Various types of antennas for mobile devices are used, such as helix, "inverted F", folded dipole, and retractable antenna structures, for example.
  • Helix and retractable antennas are typically deployed outside, i.e., on the exterior of, a mobile device, and inverted F and folded dipole antennas are typically within (i.e., on the interior of) a mobile device case or housing adjacent the top thereof.
  • internal antennas allow cell phones to have a smaller footprint than do external antennas. Moreover, they are also are preferred over external antennas for mechanical and ergonomic reasons. Internal antennas are also protected by the mobile device housing and therefore tend to be more durable than external antennas. External antennas may be cumbersome and make the mobile device difficult to use, particularly in limited-space environments.
  • RF energy radiation absorbed by the body will typically increase.
  • SAR specific absorption rate
  • U.S. Patent No. 6,741,215 to Grant et al .
  • This patent discloses various cellular phones with internal and external antenna configurations in which the antennas are positioned at the bottom of the phone to reduce radiation intensity experienced by a user, i.e., by moving the antenna farther away from the user's brain.
  • the housing of the phone forms an obtuse angle so that the bottom portion of the housing angles away from the user's face.
  • antenna configurations which allow for reduced radiation exposure
  • further advancements in antenna configurations, particularly internal antennas may be desirable to allow for further reductions in overall device size while still providing relatively low SAR values.
  • a mobile wireless communications device may include a housing and a multi-frequency band antenna carried within the housing. More particularly, the multi-frequency band antenna may include a main loop conductor having a gap therein defining first and second ends of the main loop conductor, a first branch conductor having a first end connected adjacent the first end of the main loop conductor and having a second end defining a first feed point, and a second branch conductor having a first end connected adjacent the second end of the main loop conductor and a second end defining a second feed point. Moreover, a third branch conductor has a first portion within the main loop conductor, and a second portion connected to the second feed point.
  • the antenna may further include a tuning branch conductor having a first end connected to the main loop conductor between the respective first ends of the first and second branches.
  • the multi-frequency band antenna may therefore be arranged to take up a relatively small footprint yet still provide desired performance.
  • the antenna configuration allows for convenient positioning at the bottom of a mobile device (e.g., cellular phone) printed circuit board (PCB), which aids in complying with applicable SAR requirements.
  • PCB printed circuit board
  • This configuration may also allow for less impact on antenna performance due to blockage by a user's hand. That is, users typically hold cellular phones toward the middle to upper portion of the phone housing, and are therefore more likely to put their hands over such an antenna than they are an antenna positioned adjacent the lower portion of the housing.
  • the first portion of the third branch conductor may comprise a loop and/or a patch.
  • the second portion of the third branch conductor may be connected to the second feed point via the second branch conductor.
  • the main loop conductor may have a generally rectangular shape with opposing first and second sides and opposing first and second ends, and the gap may be in the first side of the main loop conductor. Moreover, the respective first ends of the first branch conductor, the second branch conductor, and the tuning branch conductor may be connected to the first side of the main loop conductor.
  • the main loop conductor may include non-planar portions to provide further space savings, for example.
  • the main loop conductor may advantageously have at least one tuning feature therein.
  • tuning features may include meanders, zig-zags, loops, as well as other geometrical shapes.
  • the first, second, and/or tuning branch conductors may also include similar tuning features therein.
  • the mobile wireless communications device may further include a dielectric substrate supporting the multi-frequency band antenna, and the main loop conductor, first and second branch conductors, and tuning branch conductor may each comprise a respective conductive trace on the dielectric substrate.
  • the mobile wireless communications device may also include wireless transceiver circuitry carried by the dielectric substrate and connected to the multi-frequency band antenna.
  • a method aspect of the invention is for making a mobile wireless communications device and may include providing a housing, and positioning a multi-frequency band antenna within the housing, such as the one described briefly above.
  • FIG. 1 is a schematic block diagram of a mobile wireless communications device in accordance with the present invention illustrating certain internal components thereof.
  • FIG. 2 is a front elevational view of the mobile wireless communications device of FIG. 1.

  • the cellular device 20 illustratively includes a housing 21 having an upper portion 46 and a lower portion 47, and a main dielectric substrate 67, such as a printed circuit board (PCB) substrate, for example, carried by the housing.
  • the illustrated housing 21 is a static housing, for example, as opposed to a flip or sliding housing which are used in many cellular telephones. However, these and other housing configurations may also be used.
  • circuitry 48 is carried by the dielectric substrate 67, such as a microprocessor, memory, one or more wireless transceivers (e.g., cellular, WLAN, etc.), audio and power circuitry, etc., as will be appreciated by those skilled in the art, and as will be discussed further below.
  • a battery (not shown) is also preferably carried by the housing 21 for supplying power to the circuitry 48.
  • an audio output transducer 49 (e.g., a speaker) is carried by the upper portion 46 of the housing 21 and connected to the circuitry 48.
  • One or more user input interface devices such as a keypad 23, is also preferably carried by the housing 21 and connected to the circuitry 48.
  • Other examples of user input interface devices include a scroll wheel 37 and a back button 36.
  • other user input interface devices e.g., a stylus or touch screen interface
  • the cellular device 20 further illustratively includes an antenna 45 carried within the lower portion 47 of the housing 21 comprising a pattern of conductive traces on the dielectric substrate 67, as will be discussed further below.
  • an antenna 45 carried within the lower portion 47 of the housing 21 comprising a pattern of conductive traces on the dielectric substrate 67, as will be discussed further below.
  • a user will typically hold the upper portion of the housing 21 very close to his head so that the audio output transducer 49 is directly next to his ear.
  • the lower portion 47 of the housing 21 where an audio input transducer (i.e., microphone) is located need not be placed directly next to a user's mouth, and is typically held away from the user's mouth. That is, holding the audio input transducer close to the user's mouth may not only be uncomfortable for the user, but it may also distort the user's voice in some circumstances.
  • the placement of the antenna 45 adjacent the lower portion 47 of the housing 21 also advantageously spaces the antenna farther away from the user's brain.
  • Another important benefit of placing the antenna 45 adjacent the lower portion 47 of the housing 21 is that this may allow for less impact on antenna performance due to blockage by a user's hand. That is, users typically hold cellular phones toward the middle to upper portion of the phone housing, and are therefore more likely to put their hands over such an antenna than they are an antenna mounted adjacent the lower portion 47 of the housing 21. Accordingly, more reliable performance may be achieved from placing the antenna 45 adjacent the lower portion 47 of the housing 21.
  • Still another benefit of this configuration is that it provides more room for one or more auxiliary input/output (I/O) devices 50 to be carried at the upper portion 46 of the housing. Furthermore, by separating the antenna 45 from the auxiliary I/O device(s) 50, this may allow for reduced interference therebetween.
  • I/O input/output
  • auxiliary I/O devices 50 include a WLAN (e.g., Bluetooth, IEEE 802.11) antenna for providing WLAN communication capabilities, and/or a satellite positioning system (e.g., GPS, Galileo, etc.) antenna for providing position location capabilities, as will be appreciated by those skilled in the art.
  • auxiliary I/O devices 50 include a second audio output transducer (e.g., a speaker for speaker phone operation), and a camera lens for providing digital camera capabilities, an electrical device connector (e.g., USB, headphone, secure digital (SD) or memory card, etc.).
  • WLAN e.g., Bluetooth, IEEE 802.11

  • second audio output transducer e.g., a speaker for speaker phone operation
  • camera lens for providing digital camera capabilities
  • an electrical device connector e.g., USB, headphone, secure digital (SD) or memory card, etc.
  • auxiliary I/O device(s) 50 may have input and/or output capabilities, and they need not provide both in all embodiments. That is, devices such as camera lenses may only receive an optical input, for example, while a headphone jack may only provide an audio output.
  • the device 20 further illustratively includes a display 22 carried by the housing 21 and connected to the circuitry 48.
  • the back button 36 and scroll wheel 37 are also connected to the circuitry 48 for allowing a user to navigate menus, text, etc., as will be appreciated by those skilled in the art.
  • the scroll wheel 37 may also be referred to as a "thumb wheel” or a "track wheel” in some instances.
  • the keypad 23 illustratively includes a plurality of multi-symbol keys 24 each having indicia of a plurality of respective symbols thereon.
  • the keypad 23 also illustratively includes an alternate function key 25, a next key 26, a space key 27, a shift key 28, a return (or enter) key 29, and a backspace/delete key 30.

  • the space key 27, shift key 28 and backspace key 30 are used to enter a "0" and "#", respectively, upon first actuating the alternate function key 25.
  • the keypad 23 further illustratively includes a send key 31, an end key 32, and a convenience (i.e., menu) key 39 for use in placing cellular telephone calls, as will be appreciated by those skilled in the art.
  • the symbols on each key 24 are arranged in top and bottom rows. The symbols in the bottom rows are entered when a user presses a key 24 without first pressing the alternate function key 25, while the top row symbols are entered by first pressing the alternate function key.
  • the multi-symbol keys 24 are arranged in the first three rows on the keypad 23 below the send and end keys 31, 32.
  • the letter symbols on each of the keys 24 are arranged to define a QWERTY layout. That is, the letters on the keypad 23 are presented in a three-row format, with the letters of each row being in the same order and relative position as in a standard QWERTY keypad.

  • GPRS General Packet Radio Service
  • Network access requirements vary depending upon the type of communication system. For example, in the Mobitex and DataTAC networks, mobile devices are registered on the network using a unique personal identification number or PIN associated with each device. In GPRS networks, however, network access is associated with a subscriber or user of a device. A GPRS device therefore requires a subscriber identity module, commonly referred to as a SIM card, in order to operate on a GPRS network.
  • SIM card subscriber identity module
  • the mobile device 1000 may send and receive communications signals over the communication network 1401.
  • Signals received from the communications network 1401 by the antenna 1540 are routed to the receiver 1500, which provides for signal amplification, frequency down conversion, filtering, channel selection, etc., and may also provide analog to digital conversion. Analog-to-digital conversion of the received signal allows the DSP 1580 to perform more complex communications functions, such as demodulation and decoding.
  • signals to be transmitted to the network 1401 are processed (e.g. modulated and encoded) by the DSP 1580 and are then provided to the transmitter 1520 for digital to analog conversion, frequency up conversion, filtering, amplification and transmission to the communication network 1401 (or networks) via the antenna 1560.
  • the DSP 1580 provides for control of the receiver 1500 and the transmitter 1520. For example, gains applied to communications signals in the receiver 1500 and transmitter 1520 may be adaptively controlled through automatic gain control algorithms implemented in the DSP 1580.
  • a received signal such as a text message or web page download
  • the communications subsystem 1001 is input to the processing device 1800.
  • the received signal is then further processed by the processing device 1800 for an output to the display 1600, or alternatively to some other auxiliary I/O device 1060.
  • a device user may also compose data items, such as e-mail messages, using the keypad 1400 and/or some other auxiliary I/O device 1060, such as a touchpad, a rocker switch, a thumb-wheel, or some other type of input device.
  • the composed data items may then be transmitted over the communications network 1401 via the communications subsystem 1001.
  • a voice communications mode In a voice communications mode, overall operation of the device is substantially similar to the data communications mode, except that received signals are output to a speaker 1100, and signals for transmission are generated by a microphone 1120.
  • Alternative voice or audio I/O subsystems such as a voice message recording subsystem, may also be implemented on the device 1000.
  • the display 1600 may also be utilized in voice communications mode, for example to display the identity of a calling party, the duration of a voice call, or other voice call related information.
  • the short-range communications subsystem enables communication between the mobile device 1000 and other proximate systems or devices, which need not necessarily be similar devices.
  • the short-range communications subsystem may include an infrared device and associated circuits and components, or a BluetoothTM communications module to provide for communication with similarly-enabled systems and devices.
