In a particular configuration, the output interface display can be configured as a touch-sensitive display (by touch-sensitive overlay or otherwise) to additionally provide an input interface for the user to operate the device via the display. This type of device will also often include a physical connector interface for transmitting power and (as appropriate) data signals to and from the device and/or as appropriate, and (as appropriate) ) to allow the use of bee gas L and other numbers and data networks (eg, Bluetooth,

This type of PND also includes a GPS antenna that is available to receive satellite broadcast signals including location related data and then process it to determine the current location of the device. The PND may also include an electronic gyroscope and an accelerometer that generates a velocity and relative displacement that can be processed to determine the current angular acceleration and linear acceleration and that is derived from the position information derived from the GPS signal and thus determine that the device is mounted. The signal of the speed and relative displacement of the vehicle. Typically, these features are most commonly provided in the in-vehicle navigation system, but may also be provided in the PND (if this is convenient). The utility of such PNDs is primarily manifested in their ability to determine the route between the first location (usually the origin or current location) and the second location (usually the destination). Such locations may be entered by the user of the device by any of a variety of different methods, such as by postal code, street name and house number, previously stored "well known" destinations (such as famous locations) , 144456.doc 201032391 Municipal location (such as stadium or swimming pool) or other places of interest) and destinations that are particularly fond of or recently visited. Typically, the PND is enabled by software for calculating the "best" 3go "best" route between the starting address location and the destination address location based on the map data. The "best" and "best" routes are based on predetermined criteria and are not necessarily required to be the most (four) shortest route.

Such a 5L PND can be worn on the dashboard or windshield of a vehicle, but can also be formed as part of a computer on a car-radio machine or actually formed as part of the vehicle's own control system. The navigation device can also be part of a handheld system, such as a PDA (portable digital assistant) 'media player* to subscribe to a telephone or the like, and under these conditions, the functionality of the handheld system is The software is mounted on the device to perform route calculations and to expand along the navigation of the calculated route.

The route calculation pattern of _ forms a major function, and the navigation along this route is another-main function. J44456.doc 201032391 During navigation along a calculated route, it is common for these PNDs to provide visual and/or audible instructions to guide the user along the selected route to the end of the route (ie, the desired destination) ). It is also common for the PNd to display map information on the screen during navigation, which information is periodically updated on the screen such that the displayed map information represents the current location of the device and thus represents the current location of the user or user's vehicle. (If the device is being used for in-vehicle navigation). The icon displayed on the screen usually indicates the current device location and is centered, which also displays map information and other map features for the current and surrounding roads near the current device location. In addition, depending on the situation, the navigation information may be displayed in a status column above, below or to one side of the displayed map information. An example of the navigation information includes the current road to the next bias required by the user. The distance of the voyage, the nature of the yaw, may be represented by another icon indicating a particular type of yaw (eg, left or right). The navigation function also determines the content, duration, and timing of the audible instructions that can be used to guide the user along the route. It can be understood that simple instructions such as "1 turn left and turn left" require a lot of processing and analysis. #Previously, user interaction with device 2 may be by touch screen, or alternatively or by a joystick mounted remote control, by voice activation or by any other suitable method. Although it is known that the route recalculation is performed when the user deviates from the previously calculated route (occasionally or intentionally) during navigation, the other important function provided by the device is to specify an alternative route in the immediate traffic condition.

The road and traffic bar # can be continuously monitored at the square φ H # and the route to be provided for the remainder of the journey is changed or selected due to the changed conditions associated with the initial 敎 route.

統内（例如，無線電資料系統（RDS)_交通訊息頻道（TMC)服 務）。 亦已知的係允許藉由使用者界定之準則來計算路線，例 如，使用者可能希望避開交通堵塞係报可能、被預期或當 刖占優之任何道路。器件軟體將接著使用指示特定道路上 之占優交通條件的經儲存資訊來計算各種路線，且按照很 可能的堵塞或因此之延遲的級別而對經計算路線排序。其 他基於交通資訊之路線計算及導航準則亦係可能的。 因此’可看出，交通相關資訊在計算路線且將使用者引 導至一位置時具有特定用途。在此方面，且如以上所提 到’已知的係使用由一些廣播裝置所支援之RDS-TMC設 施來廣播交通相關資訊。舉例而言，在英國，使用經分配 至被稱為「經典fm」（Classic fm)之電台的頻率來廣播一已 知交通相關資訊服務。當然，熟習此項技術者應暸解，不 同交通相關資訊服務提供者使用不同頻率。 具備用於接收RDS資料廣播之RDS-TMC接收器的PND可 解碼RDS資料廣播且擷取RDS資料廣播中所包括之TMC資 144456.doc 201032391 料。此等調頻（FM)接收器需要係敏感的。對於當前所出售 之許多PND而言，提供包含RDS-TMC調諧器之附件， RDS-TMC調諧器係在其一末端處耦合至天線且在其另一 末端處耦合至連接器以用於將RDS-TMC接收器耦合至PND 之輸入端。 使用上述天線的以上所描述之類型之器件（例如，由 TomTom International B.V.戶斤製造及供應之920 GO模型）支 援使使用者能夠自一位置導航至另一位置（特別係使用交 通相關資訊）之過程。當使用者不熟悉至此等器件正導航 至之目的地的路線時，此等器件具有極大效用。 然而，此等器件之有效性可有時視所使用之天線結構而 定。在此方面，在天線設計領域中，已知許多天線結構具 有關於RDS-TMC資料之接收的變化程度之合適性。一天 線結構為所謂的偶極天線結構，偶極天線結構具有其眾多 變體，例如，對稱偶極天線結構及不對稱偶極天線結構。 對稱偶極天線結構及不對稱偶極天線結構之有線變體包含 構成第一極及第二極之一對導線，例如，可撓性導線。對 稱天線結構最初經設計以用於對稱射頻（RF)輸入電路，對 稱天線結構僅包含連接至RF接收器之對稱雙絞電纜。將 RF變壓器提供於RF接收器中，以便將對稱天線信號轉換 成可藉由RF接收器中之合適RF放大器電路放大之不對稱 天線信號。隨著時間的過去，隨著此技術的發展，將所謂 的「饋電線」（feedline)引入至天線之設計内以用於高頻率 及/或弱信號應用，以便使天線極與天線結構待耦合至之 J44456.doc -10- 201032391 雜。Η*」（noisy)電路隔開。所使用的一類型之镇電線係以 一段同轴電纜的形式。然而，同轴電纜為具有相對於地面 電位的不相等阻抗之導體之傳輸線且因此被認為「不平 衡」。為了使極導線之對稱阻抗（平衡）匹配於饋電線之不對 稱阻抗，已知的係在極導線與饋電線之間線内置放所謂的 「平衡-不平衡轉換器」（balun)，藉此使極導線之阻抗匹 配於饋電線之阻抗，且因此減少非吾人所樂見之共模電流 以免在饋電線中流動，該流動可導致極導線輻WRF能量。 不幸地，儘管由同軸饋電線所提供之極隔開，但包含上 述類型之極導線及同軸饋電線的天線結構仍易受到來自相 鄰電器件及/或電子器件（例如，PND及/或電力供應器或變 壓器，例如，點煙器轉接器（CLA))之電磁干擾（EMI)。在 此方面，不同於經整合至車輛（例如，汽車）内之電子系 統’ PND在射頻下相對於地面「漂浮」，且因此，經接收 信號不係對車輛之「EMI清潔」主體進行參考，而是對 PND之「雜訊」地面參考進行參考。此外，自pND之製造 商之觀點而言，不需要要求pND之使用者將天線連接至車 輛之主體以便獲得所要「清潔」地面參考。 即使考慮由同轴饋電線所提供之距離，然而，天線極仍 經定位成非常靠近EMI「雜訊」PND。此外，由於來自 PND及/或CLA之EMI發射，同軸饋電線亦易受到誘發性共 模電流。誘發性共模電流在同軸饋電線中流動朝向天線之 極，藉此藉由增加在由天線所產生之RF信號中雜訊之位準 而使天線之效能降級。 144456.doc -11 - 201032391 因此，在一些情況下，天線效能可不充分，從而導致 PND不接收任何資料或僅接收部分資料。自pND之使用者 之觀點而言，使用者僅察覺到無或不完全交通資訊係可用 的，且可錯誤地推斷出PND及/或TMC附件發生故障。 用以減少RF信號之外部干擾源之影響的其他解決方案係 已知的。舉例而言，可在特定頻率範圍方面屏蔽能夠發射 電磁輻射之外部源。然而，此等解決方案係昂貴的，且可 導致關於（例如）熱耗散之其他問題。另外，當電路設計改 變時’針料磁屏蔽所進行之提供可亦需要修改。因此， 設計成本及實施成本以及電磁輻射屏蔽解決方案之可再使 用性之缺乏使電磁輻射之外部源（例如，pND)之電磁屏蔽 不良。 歸因於上述非吾人所樂見之EMI的存I，在叩接收器之 輸入端處接收到所要之RF.號與非吾人所樂見之emi信號 的組合。雖然有可能增加汉？接收器之敏感度，但增加之敏 感度未用以增加RF接收器之信雜比（SNR)，且因此，未輔 助區別吾人所樂見之信號與非吾人所樂見之信號的過程。 【發明内容】 根據本發明之第一態樣，提供一種天線配置裝置，其包 含：偶極接收天線，其具有第—極部分及帛二㈣分；— 段同轴電纜’其構成饋電線；第一共模濾波器及第二共模

It is also known to allow the route to be calculated by criteria defined by the user, for example, the user may wish to avoid any roads that may be expected, expected or prevailed by the traffic jam. The device software will then use the stored information indicating the dominant traffic conditions on a particular road to calculate the various routes and rank the calculated routes according to the level of likely blockage or hence delay. Other route calculation and navigation guidelines based on traffic information are also possible. Therefore, it can be seen that traffic-related information has a specific purpose when calculating routes and directing users 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 broadcasters. For example, in the United Kingdom, a known traffic related information service is broadcast using a frequency assigned to a station called "Classic fm". Of course, those skilled in the art should be aware that different traffic-related information service providers use different frequencies. A PND with an RDS-TMC receiver for receiving RDS data broadcasts can decode the RDS data broadcast and extract the TMC 144456.doc 201032391 included in the RDS data broadcast. These frequency modulated (FM) receivers need to be sensitive. For many PNDs currently sold, an accessory is provided that includes an RDS-TMC tuner that is coupled to the antenna at one end and to the connector at the other end for RDS The TMC receiver is coupled to the input of the PND. Devices of the type described above using the above antennas (eg, the 920 GO model manufactured and supplied by TomTom International BV) support enabling users to navigate from one location to another (especially using traffic related information) process. These devices are extremely useful when the user is unfamiliar with the route to which the device is navigating to the destination. However, the effectiveness of such devices may sometimes depend on the antenna structure used. In this regard, in the field of antenna design, many antenna structures are known to have a suitability for varying degrees of reception of RDS-TMC data. The one-day line structure is a so-called dipole antenna structure, and the dipole antenna structure has many variations thereof, such as a symmetric dipole antenna structure and an asymmetric dipole antenna structure. The wired dimorph of the symmetric dipole antenna structure and the asymmetric dipole antenna structure includes a pair of conductors constituting one of the first pole and the second pole, for example, a flexible conductor. The symmetrical antenna structure was originally designed for use in a symmetric radio frequency (RF) input circuit, and the symmetrical antenna structure only included a symmetrical twisted pair cable connected to the RF receiver. An RF transformer is provided in the RF receiver to convert the symmetrical antenna signal into an asymmetrical antenna signal that can be amplified by a suitable RF amplifier circuit in the RF receiver. Over time, as this technology evolves, so-called "feedlines" are introduced into the design of the antenna for high frequency and/or weak signal applications in order to couple the antenna pole to the antenna structure. To J44456.doc -10- 201032391 mixed. Η*” (noisy) circuits are separated. One type of town electrical wire used is in the form of a length of coaxial cable. However, a coaxial cable is a transmission line of a conductor having unequal impedance with respect to ground potential and is therefore considered "unbalanced". In order to match the symmetrical impedance (balance) of the pole conductor to the asymmetrical impedance of the feeder, it is known to have a so-called "balun" built into the line between the pole conductor and the feeder. Matching the impedance of the pole wire to the impedance of the feeder, and thus reducing the common mode current that is not desired by the person to avoid flow in the feeder, which flow can cause the pole wire to radiate WRF energy. Unfortunately, antenna structures comprising pole wires and coaxial feeds of the type described above are still susceptible to from adjacent electrical devices and/or electronic devices (eg, PND and/or power, despite the extreme separation provided by the coaxial feed lines). Electromagnetic interference (EMI) from a supplier or transformer, such as a cigarette lighter adapter (CLA). In this respect, unlike an electronic system 'PND integrated into a vehicle (eg, a car) that "floats" relative to the ground at radio frequencies, and therefore, the received signal is not referenced to the "EMI Clean" body of the vehicle, Instead, reference the PND's "noise" ground reference. In addition, from the point of view of the manufacturer of the pND, there is no need for the user of the pND to connect the antenna to the body of the vehicle in order to obtain the desired "clean" ground reference. Even considering the distance provided by the coaxial feed, the antenna pole is still positioned very close to the EMI "noise" PND. In addition, coaxial feeders are also susceptible to induced common mode currents due to EMI emissions from PNDs and/or CLAs. The induced common mode current flows in the coaxial feed line towards the pole of the antenna, thereby degrading the performance of the antenna by increasing the level of noise in the RF signal generated by the antenna. 144456.doc -11 - 201032391 Therefore, in some cases, the antenna performance may be insufficient, resulting in the PND not receiving any data or receiving only part of the data. From the point of view of the user of the pND, the user only perceives that no or incomplete traffic information is available, and can erroneously conclude that the PND and/or TMC accessory has failed. Other solutions for reducing the effects of external sources of RF signals are known. For example, an external source capable of emitting electromagnetic radiation can be shielded in a particular frequency range. However, such solutions are expensive and can lead to other problems with, for example, heat dissipation. In addition, the provision of the magnetic shield of the needle material may also need to be modified when the circuit design changes. Therefore, design and implementation costs, as well as the lack of reusability of electromagnetic radiation shielding solutions, make electromagnetic shielding of external sources of electromagnetic radiation (e.g., pND) poor. Due to the above-mentioned EMI stored by the non-self, the combination of the desired RF. number and the emi signal that is not seen by the person is received at the input of the 叩 receiver. Although it is possible to increase Han? The sensitivity of the receiver, but the increased sensitivity is not used to increase the signal-to-noise ratio (SNR) of the RF receiver, and therefore, does not aid in the process of distinguishing between signals that are preferred by us and signals that are not readily available to us. SUMMARY OF THE INVENTION According to a first aspect of the present invention, an antenna configuration apparatus includes: a dipole receiving antenna having a first pole portion and a second (four) minute; a segment coaxial cable constituting a feeder; The first coaxial cable of the first common mode filter and the second common mode filter 4 has a proximal end with respect to the first pole portion and the second pole portion, and is opposite to the first pole portion and the second pole portion The distal end of the coaxial end (176) is coupled to the first pole portion and the second pole portion via a second common 144456.doc 201032391 filter, and the coaxial cable (176) The distal end is coupled to the first common mode filter. The length of the first pole portion may correspond to between about one third of a predetermined wavelength of a radio frequency (RF) signal to be received in use and about one quarter of a predetermined wavelength. The length of the second pole portion may correspond to between about one third of a predetermined wavelength of a radio frequency (RF) signal to be received in use and about one quarter of a predetermined wavelength. The apparatus can further include a first length of single axis electrical conductor that acts as a first pole portion. The apparatus can further include a second length of single-axis electrical conductor that acts as a second pole portion. The first pole portion and the second pole portion can be configured to form a symmetric dipole receiving antenna. The first pole portion can be between about 50 cm and about 75 cm in length. The first pole portion can be between about 50 cm and about 75 cm in length. The first common mode filter can have a common mode impedance between about 1 〇〇〇 Ω and about 4000 Ω. The first common mode filter can have a common mode impedance of about 2200 Ω. The second common mode filter can have a common mode impedance between about 1 〇〇〇 Ω and about 4000 Ω. The second common mode filter can have a common mode impedance of about 22 〇〇 Ω. The apparatus can further include an amplifier coupled in-line between the proximal end of the length of the coaxial cable and the first pole portion and the second pole portion. An amplifier can be coupled between the proximal end of the length of the coaxial cable and the second common mode filter. The amplifier can be coupled between the second common mode filter and the first pole portion and the second pole 144456.doc -13- 201032391 portion. For example, the second aspect of the invention provides a receiving device comprising: an antenna configuration device according to the first aspect of the present invention; and a tuner's wire-to-co-mode chopper. The tuner can be a frequency modulation (FM) tuner. The tuner can be a radio data system R tuner.呪 S S) The parent communication channel (TMC) device can include a coupling power for communicating the data decoded by the tuner to the device. The device can be a device capable of processing the data decoded by the tuner, such as a navigation device, a communication device, or any other suitable electronic device such as a 'music or other type of media player. According to a third aspect of the present invention, there is provided a portable navigation device comprising an antenna configuration device or receiving device as set forth above in relation to the first aspect of the invention or the second aspect of the invention, respectively. According to a fourth aspect of the present invention, there is provided a method of reducing a common mode signal in an antenna configuration apparatus, the method comprising: providing a dipole antenna having a first pole portion and a first pole portion; providing a relative polar portion relative to the first pole portion And a proximal end of the second pole portion and a length of coaxial cable relative to the distal ends of the first pole portion and the second pole portion; and engaging the distal end of the coaxial cable to the first common mode filter And coupling the proximal end of the length of the coaxial cable to the first pole portion and the second pole portion via the second common mode filter. This section of coaxial cable can constitute a feeder. Additional advantages and features of each of these embodiments are set forth in the accompanying claims. Therefore, it is possible to provide a device and method that is less susceptible to common mode signals. Therefore, the structure of the improved receiving antenna configuration device which is possible by the improved signal receiving system, thereby causing information (e.g., traffic related information such as RDS_TMC data), is also simple and economical to manufacture. The use of the common mode filter isolates the dipole of the antenna from the common mode signal induced in the (four) feed line at the tuner and antenna poles. The pole of the antenna can be achieved with other common mode signals (e.g., common mode signals caused by the parasitic capacitance of the device to which the device can be coupled) or improved isolation from the power supply. Furthermore, the current connection between the antenna and the chassis of the vehicle is not necessary. Also, the shield of the coaxial cable of the feeder is not part of the antenna and is therefore not sensitive to EMI. Therefore, the feeder increases the distance between the EMI source and the antenna structure. Thus, improved flexibility in mounting the device is provided, including the ability to wrap the coaxial feed (if necessary). In addition, the apparatus and method are not necessarily application specific, φ and thus provide a flexible solution for different receiving applications. The improved performance provided by the apparatus and method also reduces instances of user annoyance and erroneous inquiry by the manufacturer, distributor, and/or retailer regarding allegations of faulty equipment.

In this example, the first filter 3〇2 and the second filter 17 have respective common mode impedances of about 2.2 kQ. This significantly exceeds the inherent common mode impedance of a cable of length. The differential mode impedance of the first filter 302 and/or the second filter 17〇 may be between about 1 Ω and about 50 Ω, for example between about i Ω and about 2 〇Ω, such as at about 5 ω Between approximately 1 5 Ω. In this example, filter 170 has a differential mode impedance of about 1 〇 Ω. The common mode impedance and the differential mode impedance of the first filter 3〇2 and the second filter 170 need not be the same. The antenna configuration device 162 also includes a second common mode filter i 7 〇 and a dipole receiving antenna 172. The dipole antenna 172 includes a first pole portion 174 formed of a conductor of a first length (e.g., a uniaxial conductor) and a second pole portion 175 formed of a conductor of a second length (e.g., another uniaxial conductor). The second terminal 190 of the second filter 170 is coupled to one end of the first pole portion 174, and the fourth terminal 192 of the second filter 170 is coupled to one end of the second pole portion 175. In use, the poles of the dipole antenna 172 are configured by the user to expand substantially or substantially away from one another to ensure proper operation of the antenna configuration device 162. The first length of the first pole 174 corresponds to a quarter (λ Μ) of the wavelength of the signal that needs to be received (e.g., a wide 144456.doc • 22· 201032391 broadcast signal, such as an FM signal containing RDS-TMC data). Thus, in this example, the length of the first pole portion 174 is about 75 cm. Similarly, the second length of the second pole ι 75 corresponds to a quarter (λ/4) of the wavelength of the signal that needs to be received. Thus, in this example, the dipole antenna 1 72 is symmetrical and the second pole portion 175 is also about 75 cm in length. In the above examples, the lengths of the 'pole portions are substantially equal. In another embodiment, the dipole antenna 172 is asymmetrical. The first length of the first pole portion 174 also corresponds to one-quarter (λ/4) of the wavelength of the signal (e.g., broadcast signal 'such as 'FM signal containing RDS-TMC data) to be received. Thus, in this example, the length of the first pole portion 174 is again about 75 cm. However, the second length of the second pole portion 175 corresponds to one-third (λ/3) of the wavelength of the signal that needs to be received. Thus, in this example, the second pole portion 175 has a length of about 5 〇 cm. The length of the first pole 174 and the second pole 175 may correspond to between about one-third of the wavelength of the signal that needs to be received and about one-quarter of the wavelength, and therefore, those skilled in the art should understand that Other dipole configurations not described in this document. In any of the above embodiments, an amplifier or amplifier circuit can be provided in-line between the proximal end 1 83 of the length of coaxial cable 1 76 and the first pole portion 174 and the second pole portion 175. Therefore, the antenna configuration device 162 is "active". In an embodiment (Fig. 6), an amplifier can be coupled between the common mode filter 170 and the first pole portion ι 74 and the second pole portion ι 75. In this aspect, the third terminal 19 of the second common mode filter 170 is coupled to the output terminal 2 of the RF amplifier circuit 202. The input terminal 2〇4 of the RF amplifier 2〇2 is coupled to the first pole portion 174. . The ground terminal 206 of the RF amplifier 202 is coupled to a fourth terminal 192 and a second pole portion 175 of the common mode filter 170 of 144456.doc -23-201032391. In another embodiment (Fig. 7), amplifier 202 is coupled between second common mode filter 170 and proximal end ι 83 of the length of coaxial cable ι76. In this regard, the second terminal 182 of the core 180 of the length of the coaxial cable 176 is coupled to the wheel terminal 2 of the RF amplifier 202, and the input terminal 2〇4 of the RF amplifier 202 is coupled to the second common mode filter Π0. The first terminal 186 and thus is coupled to the first pole portion 174 via the first ferrite 170. The ground terminal 206 of the rF amplifier 2〇2 is coupled to the shield 178 of the coaxial cable 176 and the second terminal i8s of the second common mode waveguide 170 and is thus coupled to the second via the second filter 17〇 Pole part 175. Of course, it should be understood that in the examples set forth above, the RF amplifier circuit 202 can be any suitable RF amplifier, such as a low noise amplifier (LNA), such as an RF transistor (eg, a part available from Infineon Technologies AG). No.: BFR 93) or Νχρ semiconductor. Where RF amplifier 202 is used, the length of first pole portion 174 and/or second pole portion can be shortened to, for example, less than about 5 〇cm, for example, less than 2 〇 cm, such as at about 15 cm. Between about 20 cm. Referring to FIG. 8, in order to compensate for the capacitive effect caused by the use of the shorter pole portion, the third terminal I90 of the second filter 170 and the fourth terminal 192 and the second terminal of the first pole portion 174 or the filter 17A may be A compensation inductance is provided within the line between portions 175, such as coil 310, such as! The coil of μΗ. Depending on the length of the field portions 174, 175, the inductance of the compensation inductance can be between about 250 η Η and about i. 25 μ 。. Referring back to FIG. 4, in operation, the first common mode interference current component flows from the CLA 150 to the docking station 14 and thus to the navigation device 144456.doc -24 - 201032391 100, the first common mode interference current component icm CLA system Produced by CLA 150. Due to the parasitic capacitance existing between the ground 153 and the navigation device 1 ,, the second common mode interference current component iem pnd flows into the surface power buffer 160. In effect, the second common mode interference current component icm PND flows into the coupled electron microscope 160 regardless of whether the CLA 150 is coupled to the cigarette lighter of the vehicle and/or is present. Further, the third common mode current component icm EM is induced in the pole portions 174., 175 of the dipole antenna 172 by electromagnetic light emitted from the navigation device 1. The presence of the first filter, waver 1 70 is used to isolate the dipole receiving antenna 172 from the above common mode current component, and thus the performance of the 'dipole receiving antenna 172 is significantly improved, for example, by about 20 dB. In the absence of the second filter 170, the coupling cable 161 is a so-called "hot circuit" or "EMC hot" and exhibits a radiating antenna-like behavior. Due to the conducted interference and interference surface, the second ferrite 170 is provided to reduce the common mode current from flowing in the feed line 176. However, there is a residual EM field coupled from the electromagnetic radiation emission (eg, from the navigation device ') but the residual current flowing in the feed line 170 due to the emission from the navigation device ι is also filtered by the second The device is reduced by 17 turns. Again, due to the distance of the dipole receiving antenna 172 from the electromagnetic radiation source (ie, the navigation device 100) and the attenuation of the electromagnetic radiation power as a function of the distance from the navigation device 1 ,, the dipole receiving antenna 丨 72 flows. The amount of induced common mode current is significantly minimized. The differential mode current signal generated in the receive antenna 172 is thus received by the receiver 164 along with the reduced common mode current component and before being communicated to the navigation device 1 via the input port 125 of the navigation device 100. The solution 144456.doc -25- 201032391 Modulation and Decoding is used for use by the traffic data processing module 136 of the application software 134. The differential mode current is hardly affected by the presence of the first common mode filter 3〇2 and the second common mode filter 170. In another embodiment (Fig. 8), any of the above embodiments may be modified such that the receiver is disposed within the outer casing of the docking station 140. In this embodiment, the first filter 3〇2 is contained within the outer casing of the docking station 14〇. In yet another embodiment, the feeder 76, the LNA circuit, the second filter 170, any optional inductance, and the _ pole portion 174 and the second pole portion 175 are also disposed within the housing of the docking station 140. In another embodiment, the first filter 3〇2 and the second filter 170 may be used in conjunction with a pole extension portion coupled to the second pole 175 at one of the ends of the second pole portion 175, for example.
