Definitions
- Radio-mobile antenna for a small receiver.
- the invention relates to the reception and transmission of radio signals.
- the invention applies to any terminal equipped with a radio type transmission / reception module requiring an antenna.
- terminals are miniaturized more and more; for example, smartphones, or small terminals for TVs to download and decode audiovisual programs on an Internet network, which are in the form of small housings or electronic keys to connect to the TV.
- the limited space on the terminal does not allow to have an antenna of sufficient size for good quality reception.
- antennas of reduced size for example consisting of a wire arranged on a small printed circuit.
- These antennas have a certain number of drawbacks: first of all, such an antenna exhibits a reception quality lower than that of larger antennas. If the quality of reception is insufficient, the rate necessary for the correct reproduction of the audiovisual content may not be reached, which results in a number of troublesome problems in the rendering on the television (image not received, degraded, frozen, deformed, etc.); moreover, the arrangement of the antenna is not modifiable, while it is well known that a change of orientation of such an antenna can often greatly increase the quality of reception; moreover, in the case where two antennas are desirable, in particular to improve the reception, it is necessary to respect between them a certain spacing, which is not possible with this type of antenna since the support (the terminal) imposes size constraints. It should be noted in addition that some terminals of this type, such as electronic keys, are placed behind the televisions, which reduces the sensitivity and therefore the effectiveness of their antenna.
- the subject of the invention is a system comprising a terminal and at least one cable,
- the terminal comprising:
- a data transmission / reception module to be restored on a rendering device, said data being received or transmitted by at least one antenna
- a module for connection to a power supply device via a power supply support able to carry a power supply
- the cable comprising:
- the cable further comprises said antenna and that the antenna is electrically independent of the connector.
- module may correspond to both a software component and a hardware component or a set of hardware and software components, a software component itself corresponding to one or more computer programs or subprograms or more generally any element of a program capable of implementing a function or a set of functions as described for the modules concerned.
- a hardware component corresponds to any element of a hardware set (or hardware) able to implement a function or a set of functions for the module concerned (integrated circuit, smart card, memory card, etc. .).
- antenna is here conventionally meant one or more devices for radiating (transmitter) or capture (receiver), electromagnetic waves.
- the antenna converts existing electrical quantities in a conductor or a transmission line (voltage and current) in electromagnetic quantities in space (electric field and magnetic field), this in transmission and conversely in reception.
- the shape and dimensions of an antenna are extremely variable.
- a television signal receiving antenna may take the form of a metal rake or a coaxial cable, for example.
- cable is meant here a bundle of son protected by an insulating envelope, or sheath.
- the cable may itself consist of several cables, or set of wires, each making a particular function (communication, power supply, etc.), connecting the two ends of the cable and able to support a standardized protocol (HDMI for "High Definition Media Interface ", MHL for” Mobile High Definition Link “, USB for” Universal Serial Bus “, etc.)
- power support is meant a cable carrying at least one supply means for the terminal.
- Any cable that supports a power supply can be used: USB-type serial cable, power cable, telephone cable, Ethernet cable, MHL audio-visual data cable, etc.
- communication medium means a means of communication for the terminal.
- Any cable or connector offering a data exchange can be used: cable or serial connector type USB, telephone, Ethernet, audiovisual data transmission type HDMI or MHL, etc.
- connector a device adapted to ensure the connection of electrical cables subjected to currents of greater or lesser intensity at the end of the cable.
- computer connectors also called “input-output connectors”
- input-output connectors are interfaces for connecting equipment using cables. They usually consist of a male plug, with pins (English pin) protruding, to fit into socket (sockets), made of sockets home.
- the pins and sockets of the connectors are usually connected to electrical wires constituting the cable.
- the association of the pins with each wire of the cable is called pin layout.
- Each numbered pin usually corresponds to a wire of the cable, but sometimes one of the pins, as well as the corresponding wire, if present, is not used.
- the WIFI antenna of a small transceiver terminal such as an electronic key is generally located in the terminal (printed circuit comprising for example a wire).
- the invention by introducing the antenna into the communication or power supply cable, offers the advantage of moving it in a cable which is already used to transport the terminal power supply or data to be restored, and which is therefore necessary in the system.
- the antenna does not modify the electrical characteristics of the cable connector, that is to say that it does not use the active wires of the cable (those which are used for example for the transport of the data or for the power supply) to transmit radio signals.
- the antenna coexists with the cable but does not use its son.
- the invention advantageously mutualises the cable, which is necessary for the terminal, and therefore always present, and the antenna.
- the invention makes it possible, by extracting the antenna of the terminal, to reduce the size thereof. It also makes it possible to offer an antenna of better quality, since it is less limited in size, the only limit being the length of the cable.
- the antenna can be moved (with the cable that supports it) to improve the reception or rebroadcast of the broadcast signal according to the location and orientation of the antenna of the terminal.
- the antenna is less fragile, since protected by the cable sheath and outside the terminal.
- the invention can thus be used for radio terminals (radio sets with an antenna integrated in the power cable), television (HDMI key for rendering a digital television content on the television to which it is connected), retransmission of Wifi radio waves (so-called "Wifi modem”), etc.
- a system as described above is characterized in that the antenna is a coaxial cable.
- a coaxial cable is an asymmetrical transmission line or link, used at high frequencies, consisting of a two-conductor cable.
- the central core which may be single-stranded or multi-stranded (copper or copper-plated steel), is surrounded by a dielectric material (insulator).
- the dielectric is surrounded by a conductive braid (or rolled aluminum foil), then an insulating and protective sheath. It can be shielded.
- the antenna according to this embodiment of the invention is advantageously constituted by a simple cable whose metal core plays the role of transceiver.
- the antenna furthermore does not disturb the communication or power supply cable.
- the particular shape of the coaxial cable makes it possible not to produce (and not to capture) disturbances on the neighboring signals.
- the shielding of electrical wires reduces the emission of electric fields along the entire length of the circuits.
- a system as described above is characterized in that the length of the antenna is adapted to the type of signal carried.
- the length of the antenna is limited according to the invention only by the length of the cable that carries it.
- the optimal length of an antenna depends on the wavelength (and therefore the frequency) used for the chosen radio technology.
- a Bluetooth antenna does not have the same ideal length as a Wi-Fi antenna. It also depends on the mechanical characteristics (the nature of the conductor and its dimensions, the diameters of the sheath and the central conductor, the nature of the dielectric) and electrical (its characteristic impedance, its attenuation constant, etc.)
- Each antenna can thus, according to the invention, be sized to its ideal length by a simple calculation within the reach of the skilled person.
- this length can be of the order of fifteen centimeters.
- a system as described above is characterized in that the connector comprises at least one unused pin and in that said at least one antenna leaves the connector via this pin before being connected to the data transmission / reception module.
- this embodiment makes it possible to benefit from the electrical connector of the cable without modifying its mechanical or electrical behavior.
- a free pin of the cable is used to pass the antenna cable. This is output from the terminal side and can be easily connected to the antenna signal receiving circuit.
- An example will be given later in the context of the HDMI standard.
- a pin specified by the standard, but which is not used in the context of the invention, may be used for the antenna.
- the data wires can be used for the antenna, in which case the antenna is advantageously connected to the wire. unused, or alternatively this wire is removed to make room for that of the antenna.
- USB type cable comprises the support of food.
- this embodiment allows pooling the power cable, which is necessary for the terminal, and therefore always present, and the antenna.
- This embodiment is particularly useful if only the power supply part of a USB type cable is used, in order to provide the power supply that is not present in the data cable, for example of the HDMI type.
- a system as described above is characterized in that the HDMI type cable comprises the communication medium .
- this embodiment makes it possible to pool a cable for transporting audiovisual data of known type with the receiving antenna.
- the HDMI (High Definition Multimedia Interface) standard specifies a set of standards for the transport of audiovisual data. It defines in particular an electrical and logical interface allowing a transfer of uncompressed multimedia digital data in high definition. It is now widely used for the transportation of digital audiovisual data.
- the HDMI cable can for example be supplied with the small terminal in the form of an extension cord.
- the user then advantageously benefits from an extension that allows him to connect comfortably to the HDMI port of his TV while including the receiving antenna.
- a system as described above is characterized in that the cable comprises the feed support and the communication medium, and in that it is of the MHL type.
- this embodiment makes it possible to pool a cable for transporting and supplying audiovisual data of known type with the receiving antenna in a cable of the MHL type.
- the interface MHL Mobile High-Definition Link or, in French, "high-definition mobile interface” allows in particular to connect mobile terminals to televisions and high-definition monitors.
- This interface was created by the consortium of the same name in 2010.
- the MHL interface provides several simultaneous functions, including the transfer of the image in very high quality and sound in the form of uncompressed audio tracks, but also of reloading. terminal. It corresponds to an evolution of HDMI but also allows to get rid of another power source; it is therefore gradually replaced by current HDMI cables.
- the cable MHL can be supplied with the terminal, for example the electronic key, in the form of an extension.
- the user then advantageously benefits from an extension that allows him to connect comfortably at the MHL port of its TV and which includes the receiving antenna.
- a system as described above is characterized in that the cable comprises at least one antenna type Wi -Fi.
- the Wi-Fi standard is now widely used in the field of receiving audiovisual signals, particularly streaming (in French, progressive download).
- WIFI radio technology defined by the IEEE 802.1 Recommendation
- the purely receptive part of the antenna is often reduced to a simple metal rod. It is preferable, for reasons of reception performance, to replace this metal rod with a coaxial type transmission cable and to use the metallic core of the cable as a receiving antenna.
- a system as described above is characterized in that the cable comprises at least two Wi-Fi antennas of different types.
- Wi-Fi covers indeed a set of standards of the IEEE 802.11 specification. A suffix in the form of a letter makes it possible to distinguish the norms between them.
- 802.11a 5 Ghz
- b 2.5Ghz
- g 2.5Ghz
- n 2.4 or 5Ghz
- ac 5Ghz

- it can be used for specific functions that are of interest in the case of an audiovisual equipment / terminal: remote control signals, etc.
- a system as described above is characterized in that the communication medium and the power support are respectively included in two different cables, and in that each of the two cables comprises at least one antenna.
- this embodiment of the invention makes it possible to have two antennas in two separate cables, a first in the power cable, for example of the USB type, and a second in the communication cable, for example of the HDMI type. , which can be used if the reception quality is not sufficient.
- two correctly designed and positioned antennas are able to provide a better signal (and therefore, for broadcast multimedia content, a better rate) than one.
- the two antennas can be positioned independently, since they are in two different cables.
- a system as described above is characterized in that the terminal further comprises an antenna internal to said terminal .
- this embodiment of the invention makes it possible to have at least two antennas, on the one hand the native antenna of the terminal of small size, and secondly the antenna (or antennas) that is (are) in the power cable and / or in the communication cable.
- the two combined antennas are, as previously mentioned, capable of cooperatively providing an improved signal, and therefore a better bit rate than if only one antenna were used. It is thus possible to retain the advantages of the existing small terminal (with its integrated antenna) while considerably improving the reception quality in contexts where a higher reception quality is desired.
- a system as described above is characterized in that it further comprises a selection module of 'antenna.
- the antenna selection module is adapted to select, depending on the case, one or the other, or both, or more, antennas. This feature is particularly interesting in the case where the reception requires the active presence of several antennas (internal and / or external), or when a problem occurs on the external antenna (offering in this case the possibility of activating the antenna internal, even if it offers a degraded reception of the signal, while waiting for the resolution of the problem on the external antenna).
- the invention also relates to a cable comprising:
- a power supply able to carry a power supply to a terminal and / or a communication medium able to exchange data with a reproduction device
- the cable being characterized in that it further comprises said antenna and in that the antenna is electrically independent of the connector. All the advantages mentioned previously for the system can be transposed to the cable.
- this type of cable can be provided as an extension (HDMI, MHL, etc.) with the small module. It can measure a few centimeters, typically fifteen, to provide a good reception quality while facilitating the connection of the key to the back of the TV.
