Description of the Invention: Field of the Invention The present invention relates to antenna configuration devices of the type, for example, for receiving radio frequency signals of electronic devices (e.g., navigation crying or overnight devices). The present invention is also directed to a receiver device of the type, for example, for receiving radio frequency signals from an electronic device (e.g., a navigation device or a communication device). The present invention is directed to a method of reducing common mode interference signals, for example, to receive a type of radio frequency signal in the presence of a common mode interference current generated by an external source. [Prior Art] Including GPS ( Global Positioning System (GPS) signals receiving and processing functional portable computing devices (such as 'portable navigation devices (PND)) are well known and widely used as in-vehicle or other vehicle navigation systems. In general, modern PNDs include a processor, a memory, and map data stored in the memory. The processor cooperates with the memory to provide an execution environment in which the software operating system can be established, and in addition, a common one or more additional software programs are provided to enable Ability to control the functionality of the PND and provide a variety of other functions. Typically, such devices further include: one or more input interfaces that allow a user to interact with the device and control the device; and one or more output interfaces, Information may be relayed to the user by the one or more output interfaces. Illustrative examples of the output interface include: a visual display And a speaker for audible output. Illustrative examples of the input interface include: one or more physical buttons to control the on/off operation of the device or other features (if 141717.doc 201104953 the device is built to In the case of the device, the buttons may not be on the device itself, but may be on the steering wheel and the microphone for detecting the user's voice. In a specific configuration, the output interface display may be additionally configured as a touch. A sensitive display (either by touch sensitive or otherwise) provides an input interface through which a user can operate the device via the display. Devices of this type will also often include: one or more entities a connector interface through which power and (as appropriate) data signals can be transmitted to and received from the device and (as appropriate) data integrity; and (as appropriate One or more wireless transmitters/receivers that are allowed to pass through cellular telecommunications and other signal and data networks (eg, Bluetooth, Wi_Fi, Wi-Max 'GSM) The UMTS and the like also communicate. This type of PND also includes a GPS antenna by which the satellite broadcast signal including the location data can be received and then processed to determine the current location of the device. An electronic gyroscope and an accelerometer that generate signals that can be processed to determine current angular acceleration and linear acceleration, and that combine with position information derived from GPS signals to determine the speed and relative displacement of the device and thus determine the hang The speed and relative displacement of the carrier carrying the device. Typically, these features are most commonly provided in the navigation system within the vehicle, but may also be provided in the PND (if this is advantageous). The utility is mainly manifested in its ability to determine the route between the first position (usually the starting point or current position) and the second position (usually the destination) 141717.doc f S] 201104953. Such locations may be entered by the user of the device by any of a number of different methods, such as by postal code, street name and house number, previously stored "well known" destinations (such as famous locations, municipal locations ( Such as a sports field or swimming pool) or other points of interest, and a favorite or visiting destination. Usually, it is based on predetermined criteria for calculating the "best" or "best" route between the starting point address body = ground: the location of the "best" or "best" route based on the map data. And the decision must be the fastest or shortest route. The choice of route that guides the driver can be very complex, and the selection of the existing and predicted ground and/or wirelessly received traffic and road information, and the historical poor news about the road speed. And the driver's own factors for determining the choice of road = (for example, 'The driver can specify the route should not include the expressway or the toll road. This type: PND can usually be mounted on the instrument panel or the windshield can also be formed as Vehicle-on-board computer: formed as part of the vehicle's own control system. Navigation device = I: part of the palm-type system, and under these conditions, palm: type = normal functional system By installing the software on the device to perform both route 5 and navigation along the calculated route. In the case of PND, a device interacts with # ― has three different routes, the user is With the navigation month, the calculated road condition from the proposed route list selection can be avoided by the user. For example, by specifying the material journey 141717.doc 201104953 Specific routes, roads, locations or guidelines should be avoided or Mandatory intervention or guidance of the route «Selection process. The PND route calculation form forms a major function, and the navigation along the route is another - main function. During the navigation along the calculated route, the common system makes The PNDs provide visual and/or audible commands to guide the user to the end of the route along the selected route, ie, the desired destination. It is also common to (4) cause the PND to display map information on the screen during navigation. The information is periodically updated on the screen so that the displayed map information indicates the current location of the device and thus the current location of the user or user's vehicle (if the device is being used for navigation within the vehicle). The icon on the screen usually indicates the current device location and is centered. The map information of the current and weekly roads near the current device location and its map features are also displayed. In addition, depending on the situation, the map can be displayed. The navigation information is displayed in the status bar above, below or on one side of the poor news. Examples of the navigation information include the distance from the current road to the next yaw that the user needs to take. , He nature of the yaw yaw perhaps by certain types indicate ⑽ e.g., left or right) of another icon represents. The navigation function also determines the content, duration, and timing of the audible commands. By these instructions, the user can be guided along the route. It should be understood that such as "1〇〇m and then left turn 2 = ί 里 processing and analysis. As mentioned before, with the use of the device can be fine (four) control (four), outside or by the column to hang the remote control, by The sound is activated or borrowed by the other party #1; In addition, the device can continuously monitor the road and traffic conditions, and provide or choose to change the route due to the changing conditions, on which the tour will be carried out 141717.doc 201104953 The remainder of the process 4 of various technologies (eg, mobile phone data exchange, fixed camera, GPS fleet tracking) is used to identify traffic delays and feed information to notification systems (eg, Radio Data System (RDS)). - Traffic Message Channel (Ding MC) Service. Although known to cause the device to perform route recalculation while the user deviates from the previously calculated route (unexpectedly or intentionally) during navigation, by the device Another important function provided is the automatic route recalculation in the case where an alternative traffic route would be more advantageous in the case of immediate traffic conditions. Appropriately enable the device to self Identifying such conditions, or whether the user actively causes the device to perform route recalculation for any reason. Also known is to allow routing to be calculated by, for example, user defined criteria: the user may wish to avoid Open traffic jams for any road that is likely, expected or currently dominant. The device software will then use the stored information indicating the prevailing traffic conditions on a particular road to calculate the various routes, and possibly block or The calculated route is sorted by the rank of the delay. Other route calculation and navigation criteria based on traffic information are also possible. Therefore, it can be seen that the traffic-related information is specific when calculating the route and guiding the user to a location. In this regard, and as mentioned above, it is known to broadcast traffic related information using RDS-TMC facilities supported by some broadcast stations. For example, in the United Kingdom, the use is assigned to be called "classic" The frequency of the Classic fm station broadcasts a known traffic related information service. Of course, those skilled in the art should understand that different frequencies are used by different traffic-related information service providers. It is also known to provide a PND having an RDS-TMC receiver for receiving RDS data broadcasts, decoding RDS data broadcasts, and extracting TMC data included in RDS data broadcasts. These frequency modulated (FM) receivers need to be sensitive. For many PNDs currently sold, an accessory is provided that includes an RDS-TMC tuner coupled to an antenna at one end and a RDS-TMC tuner coupled to the PND at the other end thereof An input connector. In order to manufacture an antenna in an economical manner while complying with national or regional compliance rules (e.g., rules associated with the so-called "CE marking"), it is known to form an antenna from a straight wire. However, straight wire type antennas are susceptible to EMC interference from adjacent electrical devices and/or electronic devices (e.g., PNDs and/or power supplies (e.g., firearm adapters (CLA)). In this respect, unlike an electronic system integrated into a vehicle (eg, a car), the PND is "floating" relative to the ground under radio frequency, and therefore, the received signal does not involve the "EMI cleaning" machine of the vehicle. Body, but instead involves the PND's "noise" ground reference. Furthermore, according to the manufacturer of the PND, the poor system requires the user of the PND to connect the antenna to the body of the vehicle in order to obtain the desired "clean" ground reference. The antenna is therefore positioned very close to the EMI "noise" PND. Therefore, in some cases, the antenna performance may be insufficient, resulting in the PND not receiving any data or only receiving part of the data. According to the user of the PND, the user only perceives that the traffic information is not available or that incomplete traffic information is available, and that the PND and/or TMC accessory is erroneously inferred to be malfunctioning. European Patent Publication No. EP 1 672 787 relates to a broadcast reception 141717.doc 201104953 having an antenna socket coupled to a common mode input filter of a radio tuner via a feeder line. However, the input filter requires the ground provided by the radio tuner. Unfortunately, in the case of RDS_TMC tuners and antennas, no interference-free analogs similar to the ground are available. Other solutions for reducing the effects of external sources of interference from radio frequency (RF) signals are known. For example, an external source capable of emitting electromagnetic radiation can be shielded with respect to a particular frequency range. However, such solutions are expensive and can cause other problems associated with, for example, heat dissipation. In addition, the regulations for electromagnetic shielding may also need to be modified when the circuit is changed. Therefore, the design and implementation cost of electromagnetic radiation shielding solutions and the lack of reusability make electromagnetic shielding of external sources of electromagnetic radiation poor. It should also be mentioned that although the route calculation and navigation functions are important for the overall utility of the PND, it is possible to use the device purely for information display or "free-driving", which only shows the location of the current device. Map and traffic information, and the route has not been calculated and the device is currently not performing navigation. This mode of operation is often applicable when the user has been informed of the route along which the travel is to be carried out and does not require navigation assistance. Devices of the type described above (eg, 92〇G〇 models manufactured and supplied by TomTom International BV) are provided to enable a user to navigate from one location to another (especially using traffic related information). Reliable way. These devices are extremely useful when the user is unfamiliar with the route to the destination they are navigating to.

The application software (1) provides an operating environment that includes a GUI that supports the core functions of the navigation device (e.g., 'map view, route plan, navigation function, and any other functions associated therewith). In this example, one portion of the application software 134 includes a parent-to-bee processing module 136 that receives and processes traffic-related data, and 2 users provide traffic information integrated with the map information. Since this functionality is not solely the core of the embodiments described herein, other details of the traffic data processing module 136 will not be described herein for the sake of brevity and clarity of the description. Referring to Fig. 3, in this example, navigation device 100 can be coupled to arm 14'' which can be fastened to, for example, a carrier instrument panel or a 14I717.doc 201104953 window using suction cup 142. The arm 140 is an example of a docking station to which the navigation device 1 can be coupled. For example, the navigation device 100 can be coupled to the docking station 14A or otherwise coupled to the docking station 14 by snapping the navigation device 100 to the arm 14A. The navigation device 100 can also be rotatable on the arm 14A. In order to release the connection between the navigation device 100 and the docking station 14A, a button on the navigation device 1A is provided and the button can be pressed. Alternatively, other equally suitable configurations for coupling the navigation device 100 to the docking station and decoupling the navigation device 100 from the docking station may be provided. Turning to FIG. 4, in this example, the navigation device 100 is located in a carrier (eg, a car) and is coupled to the docking station 140. The docking station 14 is coupled to a firearm adapter (CLA) 150 which is inserted into a so-called sparker (not shown) of the carrier. After proper conversion of the 12 V direct current (DC) supply provided by battery 152, the coupling of CLA 150 to the firearm of the carrier allows the battery 152 of the carrier to be used in this example via the docking station 14 The navigation device 1 is powered. Both battery 152 and CLA 150 are coupled to the ground 153' provided by the carrier, typically the chassis or body of the vehicle. The docking station 140 includes an input port 154 that is coupled to the input port 125 of the navigation device 1 when the navigation device 1 is coupled. The receiving device i 56 is coupled to the docking station 140. In this regard, the receiving device 156 includes a coupling connector (not shown) (eg, a plug) for coupling to the input port 154 that is coupled to the housing 158 via a coupling cable 160 The tuner (not shown in Figure 4). Of course, if the docking station 140 is not used, the coupling connector can be directly connected to the input port 125 of the navigation device 1 . In this example, the tuner within the housing 158 is a frequency modulated (FM) receiver, 141717.doc • 19· ί 5; 1 201104953 specifically for the RDS-TMC tuner. The appropriate receiver is available from GNS GmbH, Germany, by way of example. The splicer device 156 also includes a tuner and antenna configuration device 162' to the spectrometer to the antenna configuration device 162. Referring to Figure 5, antenna configuration device 62 includes a first length of coaxial cable 170, a filter 188, and a receive antenna 2〇4. The distal end 1 72 of the first length of coaxial cable 170 is compatible for coupling to the tuner 164. The tuner 164 is thus coupled to the first terminal 166 of the first core 168 of the first length of coaxial cable 170 at the distal end ι 72 of the first length of coaxial cable ι7〇, and the coaxial cable ι7〇 at the first length The distal end ι 72 is coupled to the first terminal ι 74 of the first shield 176. When the antenna configuration device 162 is in the deployed state, the distal end 1 72 of the first length of coaxial cable 17 is relative to the receiving antenna 204. In this example, the first length of coaxial electrical retardation 170 constitutes a split cable. The second terminal 178 of the first core 168 and the second terminal 182 of the first shield 176 at the proximal end of the split cable i 7〇 are respectively coupled to the filter at the proximal end 18〇 of the split cable 17〇 The first terminal 184 and the second terminal 186 of the device 188. When the antenna configuration device 162 is in the unfolded state, the proximal end 18 of the first length of coaxial cable 170 is tethered relative to the receiving antenna 204. Filter 188 is a common mode filter, such as a common mode transformer (such as a coil) or a toroidal inductor or a common mode current sink (e.g., a two-wire anti-々 IL device). The filter 188 is located in the second housing 1 90 and has a common mode impedance and a differential mode impedance. The common mode impedance of the filter can be at least about i. The common mode impedance can be between 1 ΙζΩ and about 4 Ω, for example between about 1 5 and about 2.5 (such as between about 2 kn and about 2.3 kfi). In this example, filter 8 8 has a common mode impedance of about 2 · 2 1 <; Ω. This significantly exceeds the inherent common mode impedance of a length of 141717.doc 201104953 cable. The differential mode impedance of filter 188 can be between about 1 Ω and about 50 Ω, for example, between about 1 ω and about 20 Ω (such as between about 5 Ω and about 15 Ω). In this example, filter 188 has a differential mode impedance of about 10 Ω. A second length of coaxial cable 196' is provided having a first end 197 and a second end 198. The third terminal 192 of the filter 188 is coupled to the second core 194 of the coaxial cable 196 of the second length at the second end 198 of the coaxial cable 196 of the second length, and the fourth terminal 200 of the filter 188 is A second shield 202 of the second length of coaxial cable 196 is coupled to the second end 198 of the second length of coaxial cable 196. A second length of coaxial cable 196 is used as the feed line portion of the dipole receiving antenna 204. The dipole antenna 2〇4 also includes a first pole portion 2〇6 formed of a conductor of a first length (eg, a uniaxial conductor), and a conductor formed by a conductor of a length of the second length (eg, another uniaxial conductor) Dipole portion 208. At a first end 197 of the second length of coaxial cable 196, the second core 194 of the feed line portion 196 is coupled to one end of the first pole portion 206 via a balun 205, and The second shield 202 of the feed line portion 196 is coupled to one end of the second pole portion 208 via a balun 205. The separation cable 170 and the feed line portion 196 together form an antenna feed line. In use, the poles of the dipole antennas 2〇4 are configured by the user to extend generally or approximately away from one another to ensure proper operation of the antenna configuration device 162. The first length of the first pole 206 corresponds to one quarter (λ/4) of the wavelength of the signal that needs to be received (e.g., a broadcast signal (such as an FM signal containing RDS-TMC data)). Thus, in this example, the length of the first pole portion 206 is 141717.doc Γ • 21 · 201104953 approximately 75 cm. Similarly, the second length of the second pole 2 〇 8 corresponds to a quarter (λ/4) β of the wavelength of the signal to be received. Thus, in this example, the dipole antenna 204 is symmetrical, the second pole The length of portion 208 is also about the length. In another embodiment, the dipole antenna 204 is asymmetrical, and the first length of the first pole portion 206 and the second length of the second pole portion 2G8 are different ratios of the wavelength (λ). In light of the above examples, it should be appreciated that any suitable receiving antenna can be used, and other embodiments of other types of antennas coupled to the split cable 17 via filter 188 are contemplated. For example, in another embodiment, the feed line portion 196 is not required to be used, and the first pole portion 2 〇 6 and the second pole portion 2 〇 8 may not need to place the feed line portion therebetween. In the case of between, lightly connect to i wave ^§ 1 8 8. In another embodiment (Fig. 6), the resonant feed line dipole antenna 21 is coupled to the split cable 17A via a filter 188. In this regard, the modulating device 64 is coupled to the split cable 170 and the split cable 17A is coupled to the filter 188 in the same manner as described above with respect to the prior embodiments. Again, filter 188 has a configuration similar to that described above with respect to the previous embodiment. Therefore, for the sake of simplicity and conciseness of the description, the connection between the tuner 164, the separation cable 17A and the filter 18 8 and the nature of the filter j 8 8 will not be described in detail again with respect to this example. . The dipole antenna 210 includes a first pole portion 212' formed of a length of conductor (e.g., a uniaxial conductor) and a coaxial shaft having a second length of the second shield 202. In this example, the second length of coaxial electrical cover 196 is used as the feed line portion 141717.doc -22. 201104953 in a manner similar to that described above with respect to the previous examples, but also constitutes the receiving antenna 210 Bipolar part. Also, as in the case of the previous example, the feed line portion 196 together with the separation cable 170 constitutes an antenna feed line. The second core 194 of the second length of coaxial cable 196 is used as a single axis electrical conductor forming the first pole portion 212. However, those skilled in the art will appreciate that a separate unshielded conductor can be used and coupled, for example, to the second core 194 of the second length of coaxial cable 196 by soldering. It can be seen from Figure 6 that the resonant feed line dipole receiving antenna 210 is fed through the end. In this aspect, the second core 194 of the second length of the coaxial cable 196 is coupled to the third terminal 192 of the ferropole 188, and the second shield 2 〇 2 of the coaxial cable 196 of the second length is lightly coupled to the filter 1 88. The fourth terminal 200. Turning to Figure 7, the first length of the first pole 212 corresponds to a quarter (λ/4) of the wavelength of the signal that needs to be received (e.g., a broadcast signal (such as an FM signal containing RDS-TMC data)). Thus, in this example, the length of the first pole portion 212 is about 75 cm. Similarly, the second length of the second pole 196 corresponds to a quarter (λ/4) of the wavelength of the signal that needs to be received. Thus, in this example, the second pole portion 196 is also about 75 cm in length. In another embodiment (Fig. 8), the first length of the first finger pole portion 212 is also

The first core 168 of the split cable 170 is lightly coupled to the first bridge contact 250. The first bridge contact 250 is coupled to the first terminal 184 of the filter 188. The first shield 176 of the split cable 170 is coupled to the first shield contact 252 and the second bridge contact 254, and the second bridge contact 254 is consuming to the second terminal 186 of the filter 188. The second core 194 of the feed line 196 is coupled to the third bridge contact 256 ′ and the third bridge contact 256 is coupled to the third terminal 192 of the filter 188. The second shield 202 of the feed line 196 is coupled to the second shield contact 2 58 and the fourth bridge contact 2 6 0 '. The fourth bridge contact 2 6 0 is connected to the fourth terminal 200 of the ferrier 1 88. As mentioned above, the filter 1 88 is placed within the housing 190, and the second end 18 of the split cable 170 and the side end 198 of the feed line 196 extend into the housing. The outer casing includes a pull-relief member 262 disposed therein to prevent separation of electricity by pulling, "see 170 and/or feed line 96". Damage to the connection between the filter 188 and the feed line 196 and the filter 188. In order to reduce the antenna configuration device 162 from being susceptible to electromagnetic interference due to the split cable 17 being coupled to the feed line 196 via the filter 188, the loop area 264 of the bridge contact is minimized and in this example is about 5 mm2 . However, the loop area 264 can be less than about 5 mm2, for example, less than about 3 _2. The bridge contacts can be provided by a printed circuit board (PCB) and the filter 188 is surface bonded to the PCB in this example. In this embodiment +, the second outer casing 19 is formed of a substantially rectangular shaped plastic case that is closed by ultrasonic waves. However, in another embodiment, the outer casing can be an encapsulant. Referring back to FIG. 4, in operation, the first common mode interference current component 141717.doc 24-201104953 flows from the CLA 150 to the docking station 140 and thus to the navigation device 1 , the first common mode interference current component icm cla Produced by CLA 150. The second common mode interference current component icm PND flows into the coupling cable 160 due to the parasitic capacitance existing between the ground 153 and the navigation device 1 。. In effect, the second common mode interference current component iemPND flows into the coupling cable 丨6〇 regardless of whether the Cla 150 is coupled to the igniter of the carrier and/or is present. In addition, the third common mode interference current component icm EM is induced in the coupling cable 160 by electromagnetic radiation emitted from the navigation device i 00 . The presence of filter 188 is used to isolate resonant feed line receive antennas 204, 2 10 from the above common mode interference current component, and thus, the performance of receive antenna 204' 210 is significantly improved up to, for example, about 20 dB. In addition, the split cable 17 is used to move the receive antennas 2, 4, 21A away from the electromagnetic interference emitted by the navigation device 100, thereby mitigating the third common mode interference current component iEM EM induced by the adjacent navigation device 100. In effect, the strength of the interfering signal received by the antenna is gradually attenuated as the length of the split cable 1 70 increases. In addition, the attenuation of the interfering signals provided by the split electrical and filter 188 is additive. At a frequency of 105.9 MHz and ignoring the benefits provided by filter 188, the attenuation of the common mode interference signal provided by the split cable ι7 配置 of the configuration of Figure 6 is shown in Table I below: 141717 .doc -25· 201104953 ~~---- Length of separation cable 170 (cm) Interference attenuation (dB) 0 0 5 2.9 10 3.6 14 5.3 18 7.4 _ 30 11.8 Table i In the case of ..., filter 188, The coupling cable 160 and the separation cable 170 are opened to the "thermal circuit" or "EMC hot" and exhibit antenna-like behavior. By providing a filter, the waveguide 180, the conductor, for example, carries the distance from the navigation device 100 when the common mode interference current induced by the electromagnetic radiation is emitted, that is, the conductors of the receiving antennas 2, 4, 210 are The only conductors of the receiving device 1 56 are that the common mode interference current can be induced into the conductors by the electromagnetic radiation emitted by the navigation device 1 . Due to the distance of the receiving antennas 204, 210 from the source of electromagnetic radiation (ie, the navigation device 1 ,), and the power of the electromagnetic light ray is attenuated by the distance from the navigation device 1 在 at the receiving antennas 204, 210 The amount of induced common mode interference current flowing in is significantly minimized. The differential mode current signal generated in the receive antennas 204, 210 is thus received by the receiver 164 with reduced common mode interference current components and input via the navigation device 1 before being communicated to the navigation device 100. The demodulation and decoding 'is used by the traffic data processing module 136 of the application software 134. The differential mode current is hardly affected by the presence of the common mode filter 188. 141717.doc -26- 201104953 It should be understood that although various aspects and embodiments of the present invention have been described so far, the present invention is not limited to the specific configuration set forth herein, but instead is expanded to cover additional applications. All configurations of the scope of the patent, as well as modifications and changes thereto. For example, although the above embodiments have been described with respect to the reception of signals, particularly RDS_TMC signals, those skilled in the art will appreciate that the above embodiments may be related to other applications (eg, digital audio broadcasting (DAB). Received (such as the Transport Agreement Professional Group (TpEG) data stream)) is used. In general, those skilled in the art will appreciate that the antenna configuration device i 62 can be used to receive signals carrying audio information, such as FM audio signals. Thus, the antenna configuration device can be used in conjunction with an FM radio application (e.g., for a satellite radio application such as that used by other electronic devices such as a device). A suitable example is to include an integrated FM receiver or to be coupled to fm. Mobile phone handset with receiver module. By other examples 'should be understood', although the above embodiments have been described in the context of navigation devices, the techniques described herein are applicable not only to navigation devices, but also to the ability to receive RF signals for this purpose (eg, FM) Any other electronic device or accessory to the RDS or RDBS data signal on the channel). Examples of suitable devices include mobile phones or media players, such as music players, which are especially (but not exclusively) MP3 players or accessories for this purpose. While the embodiments described in the above detailed description refer to GPS, it should be noted that the navigation device can utilize any kind of position sensing technology as an alternative to Gps (or indeed 'other than GPS'). For example, the navigator 141717.doc •27- 201104953 can utilize other global navigation satellite systems, such as the European Galileo system. Equally, it is not limited to satellite-based, but can function easily using a ground-based beacon or any other type of system that enables the device to determine its geographic location. It should also be well understood by those skilled in the art that while the preferred embodiment implements a particular functionality by software, the functionality is equally hardware-only (eg, by one or more ASICs (special applications) The integrated circuit)) is implemented in a fine or continuous manner by a mixture of a hard body and a soft body. Thus, the scope of the present invention should not be construed as being limited to being implemented in software.
