Definitions

  • the present invention refers to a multifunction antenna. More particularly, the present invention refers to a multifunction antenna which is generally suited to be installed on the roof panel of cars.
  • the realizations of the first type are the more reliable ones, but they are more easily installed only on luxury cars, where problems connected to the spaces required to place the systems and the production cost containment requirements are marginal.
  • the antennas and their electronic circuits tend to be comprised in a unique container which can be applied on the roof panel of cars.
  • ITN Information-Telematic Nodes
  • the most common and required realizations of multifunction systems are the ones comprising a reception antenna of the amplitude modulation (AM) and the frequency modulation (FM) radio signals together with its relevant feeding; a reception/transmission antenna of Dual Band telephony signals; a reception antenna of the GPS signals for navigation and a corresponding power supply.
  • AM amplitude modulation
  • FM frequency modulation
  • the reception function of the AM and FM radio signals and the reception/transmission function of the Dual Band telephony signals are obtained by the same rod; while the reception of GPS navigation signals is obtained by a miniaturized patch antenna.
  • the feedings reach the amplification and matching circuits both for the AM/FM reception part and for the one receiving the GPS signals through the central wire of the respective output coaxial cables.
  • the research is substantially aimed at finding economical solutions being able to face the business competition aggressiveness. All the above mentioned solutions are conceived in order to reduce the number of applied cables, their extension and the related connections, simplify the coupling means of connections, reduce the costs of the single components and times related to application, installation and maintenance interventions, the labour and the costs in general considering the technological requirements of the systems which are due to correctly operate without interference problems among the various functions.
  • the reception/transmission of Dual Band telephony signals associated to the AM and FM radio signal reception antenna rod comprises a unique coaxial cable for the connection to the ITN system which also conveys the power supply to the relevant electronic circuits, while for the reception signals of the GPS navigation systems where the risk of interferences towards other functions is very high, the connection among the antenna, the ITN system itself and the relevant feeding requires a separate coaxial cable.
  • the invention as it is, characterised by the claims, solves the problem through a multifunction roof panel antenna for cars which is comprised in a unique container including: the radio reception function in AM and FM bands, the reception/transmission function of the GSM (Global System for Mobile Communications) Dual Band (900 an 1800 MHz bands) telephone signals, the reception function of the GPS (Global Positioning System) signal and a signal mixer of these functions; the latter interfacing with an ITN (Info-Telematic Node) equipped with a suitable demixer by a unique screened coaxial cable through which the signals of all the above mentioned functions and the required feedings are properly measured, transmitted and/or received .
  • GSM Global System for Mobile Communications
  • Dual Band 900 an 1800 MHz bands
  • GPS Global Positioning System
  • ITN Info-Telematic Node
  • the container which can be applied to the roof panel of cars includes all the antennas with the relevant feeding, reception, reception/transmission electronic circuits which associate to a unique mixing circuit of the signals of the various functions.
  • Said mixer depends on a unique quick coupling output connector for a unique coaxial cable to be connected to an ITN unit placed in the dashboard; the ITN unit is equipped with one entry connector for a demixer fit for the separation of the signals of the various functions.
  • a first horizontal board 3 is placed on which, from printed circuit, a coaxial connector 4 getting into constraint and contact relation with a fixing hub 5 is integral.
  • the low noise amplification (LNA) electronic circuit for GPS signals together with a narrow band band-pass filter 7 is obtained.
  • the "patch antenna” 9 related to the same electronic circuit 6 of the GPS function is placed.
  • the electronic circuit 10 of the AM/FM radio receiving functions with the low-pass filter 11 and the connection to a vertical board 12 on which the impedance matching circuit 13 with the matching high-pass filter 14 for the Dual Band (GSM/DCS) telephony reception/transmission function and the contact with the cap 16 of the antenna rod 17 which is common for both functions is placed.
  • FIG 5 represents the whole block diagram of the above-mentioned circuits wherein the power supply point for the electronic circuit 10 of AM/FM radio reception is marked with the "a" symbol. Said reception is obtained by the block inductance "c" directly from the central wire of the unique output coaxial cable and it is connected to the GPS navigation electronic circuit 6 (in order to reduce the feeding voltage from 10-16 V to the required 3 or 5 V) through the voltage regulator 8.
  • the multifunction rod 17 is connected to the impedance matching circuit 13 and subsequently to the high - pass filter 14 through the node 16.
  • the multifunction rod itself is also connected to the two separate stages for the AM signal conditioning and the matching and/or the amplification of the FM signals. At their turn, the signals of the two stages sum up and pass through the low - pass filter 11.
  • the receiving element for the signals of the GPS 9 (which is generally a patch antenna with a circular polarization) is connected to the low noise amplification electronic circuit 6 which, in its turn, is connected to the band - pass filter 7.
  • the signals going out from the three filters 14, 11 and 7 gather together in 4 and, through the connector 18, they go to the unique coaxial cable 19 and to the signal demixing electronic circuit 21.
  • the A (870 ⁇ 960 MHz); B (1710 ⁇ 1880 MHz) GSM7DCS Dual Band telephony; C (1575 ⁇ 5 MHz) GPS navigation system; D (0-110 MHz) AM/FM radio reception and the required feedings filtered antenna signals are conveyed and mixed on the unique coaxial connector 4 which is associated to the fixing hub 5 which, through its lower threaded part 30 coupled to a nut 31 with a grip elastic element 32 and a gasket 33, acts as a constraint element of the multifunction antenna to the roof panel 2, while with its hollow central part 34 it constitutes the guiding and contact element for the same connector 4.
  • a complementary plug applied to one end of a short cable with pigtail connector to which a further coaxial cable connects can be engaged to the connector 4; a plug 18 for a unique specific coaxial cable 19 can be also engaged to the connector 4 for each type of car on which the multifunction antenna is applied.
  • Such unique specific coaxial cable 19 develops for a sufficient and right length allowing the connection with the unique connector 20 of a signal demixing electronic circuit 21 placed at the entry of the Info-Telematic Node (ITN) which is housed in the dashboard.
  • the demixer task is to separate the signals and prevent that interferences among them take place. It particularly prevents that the DCS signal at 1800 MHz go out with about 1 Watt of power from getting into the entry of the GPS receiver blocking it.
  • the main features of the signal demixer 21 essentially consist in the fact that: the insulation between DCS and GPS at 1700 MHz is comprised between 60 and 70 dB and is obtained by a filter on the GPS path of at least 50 dB and by a notch filter which is placed on the phone side producing an attenuation of at least 10 dB.
  • signals A and/or B pass through a high-pass filter 22 and a stop filter 23 at 1575 MHz with an attenuation of at least 10 dB in order to reach the Dual Band telephony transceiver set included in the ITN.
  • Signals C pass through a band-pass filter 24 at 1575 MHz with A (attenuation) > 50 dB at 1700 MHz in order to be picked up by the radio receiving set included in the ITN.
  • XX and YY represent the interface points of the electronic circuit 10 of the AM/FM radio reception which is placed on the rear part of the horizontal board 3 and of the impedance matching circuit 13 of the Dual Band telephone transmission/reception which is placed on the vertical board 12 which are associated to the same antenna 17.
  • the power supply point (of 10-16 V) of the electronic circuit 10 of the AM/FM radio reception is represented with "a”
  • "a” represents the power supply point equipped with the relevant voltage regulator 8 of the low noise amplification electronic circuit 6 of GPS signals which is placed on the front part of the horizontal board 3 and it is associated to the "patch antenna" 9.
  • "b" represents the interface point of the electronic circuits 6 and 10 towards the unique coaxial connector 4.
