Definitions
- the invention relates to a wrist-carried wireless instrument, and more particularly, to a wristwatch receiver having magnetic loop antennas embedded in the wristband.
- a loop antenna has to be understood as one single loop conductor lying substantially in the same plane, the frequency of operation of which is normally such as to give a substantially uniform current along the conductor.
- the loop antenna 101 can be formed in a unitary fashion inside the wristband 102, which is connected to the casing 103 of the wrist-carried wireless instrument 100 to form a continuous loop via a center fastening structure 104, for example a clasp, of the wristband when the band is fastened.
- the wristband 102 typically contains a wristband adjusting structure to adjust the length of the wristband to the thickness of the wearer's arm. This adjustment causes the antenna's loop length to vary from wearer to wearer, which causes variations in the receivable frequency band from one wearer to another.
- a solution consisting in providing the wireless instrument 100 with an additional apparatus for compensating changes in antenna gain and resonance frequency resulting from changes in the antenna's loop length is complex and bulky, which is not desirable in such wireless instruments.
- the wrist-carried wireless instrument 110 includes a casing 113, a center fastening-type wristband 112.
- the wristband 112 has upper 121 and lower 122 surfaces and a fastening structure 114 at its center and consists of a pair of wristband parts 112a and 112b, each of which is attached to an end of the casing 113.
- a receiving antenna 111 is mounted inside in at least one part 112a of the wristband to receive signals, the antenna 111 being connected via terminals to a reception circuit inside the casing 113.
- the loop antenna 111 extends between the upper 121 and lower 122 surfaces of the wristband 112 and does not go through the center fastening structure 114. It is to be noted that reception would be possible without having the wristband 112 attached and forming a loop, as it does when worn.
- the main object of the present invention is to realize a wrist-carried wireless instrument for receiving radio frequency signals having two loop antennas mounted inside the wristband, these antennas having improved antenna efficiency.
- reducing impact of the antenna losses can be achieved by connecting both loop antennas in parallel and, on the other hand, increasing the antenna radiation resistance can be achieved by connecting both loop antennas in series.
- the wireless instrument comprises a wristband having a first and a second band portions connected to opposite edges of a casing, each of said first and second band portions having upper and lower surfaces.
- a first and a second loop antennas are embedded respectively in said first and second band portions and extend between said corresponding upper and lower surfaces.
- Both loop antennas are connected through said opposite edges of said casing to a first and a second tuning circuits, wherein said first and second tuning circuits are connected to an antenna receiver arranged in said casing and together in a hybrid manner via an interconnection circuit, And wherein said interconnection circuit is a capacitor network comprising a first and a second capacitors connecting said first and second tuning circuits partially in parallel, and a third capacitor connecting said first and second tuning circuits partially in series.
- the present invention concerns wrist-carried wireless instrument for receiving radio frequency signals, in the frequency band from 30 to 300 MHz and preferably in the frequency band from 88 to 108 MHz using the radio data transmission system.
- the invention more particularly relates to an antenna structure having optimised antenna efficiency.
- Wireless instrument 1 comprises a wristband 2 having a first 2a and a second 2b band portions connected to opposite edges of a casing 3, each band portion having upper and lower surfaces.
- a first 4a and a second 4b loop antennas are embedded respectively in the first and second band portions 2a and 2b and extend between the corresponding upper and lower surfaces.
- Both loop antennas 4a and 4b are embedded respectively in the first and second band portions 2a and 2b and extend between the corresponding upper and lower surfaces.
- Both loop antennas 4a and 4b are connected through the opposite edges of casing 3 respectively to a first 5a and second 5b tuning circuits.
- Both tuning circuits are connected to an antenna receiver 6 arranged in said casing 3. Additionally both tuning circuits are connected together in a hybrid manner via an interconnection circuit 7 which will be more detailed with regards of Figure 2 .
- Figure 2 shows a schematic of the antenna circuits inside the casing of the wireless instrument according to a preferred embodiment of the invention.
- the numerical references have been kept unchanged for the common elements with Figure 1 .
- Both loop antennas 4a and 4b are connected to antenna receiver 6 via both tuning circuits 5a and 5b. Further, an interconnection circuit 7 is provided for interconnecting both tuning circuits 5a and 5b and then both loop antennas 4a and 4b.
- a goal of the present invention is to optimise antenna efficiency. To achieve this goal, it is important to reduce the ratio of the antenna losses over the radiation resistance, and therefore to reduce the antenna losses and to increase the radiation resistance. It has been shown in relation with the present invention that reduction of the ohmic and dielectric losses of the antennas can be achieved by connecting both loop antennas 4a et 4b in parallel. With such a parallel connection of both loop antennas, the losses are reduced by approximately 50%, while the radiation resistance is kept on a level of a single loop antenna. It has been also shown in relation with the present invention that increase of the radiation resistance can be achieved by connecting both loop antennas 4a and 4b in series. With such a series connection of both loop antennas, the radiation resistance is increased by a factor four, while the losses are only increased by a factor of about two or a little bit more, then reducing the ratio of antenna losses over radiation resistance by a factor of about two.
- interconnection circuit 7 is designed for interconnecting both tuning circuits 5a and 5b and then both loop antennas 4a and 4b in a hybrid manner between these two "extreme" connections, i.e. partially in parallel and partially in series.
- interconnection circuit 7 is a capacitor network comprising a first C P1 and a second C P2 capacitors connecting respectively both tuning circuits 5a and 5b partially in parallel, and a third capacitor C S connecting both tuning circuits 5a and 5b partially in series.
- each loop antenna is connected to the corresponding tuning circuit, respectively 5a and 5b, at two connecting points, respectively 8a, 9a and 8b, 9b.
- First capacitor C P1 is connected to connecting point 8a on one side and to connecting point 8b on the other side.
- Second capacitor C P2 is connected to connecting point 9a on one side and to connecting point 9b on the other side.
- Both tuning circuits 5a and 5b are then connected partially in parallel via both capacitors C P1 and C P2 .
- Third capacitor C S is connected to connecting point 8b on one side and to connecting point 9a on the other side. Both circuits are then connected partially in series via third capacitor C S .
- antenna receiver 6 is connected to connecting points 8a and 9b.
- both loop antennas are then connected partially in parallel and partially in series, which allow the ratio of antenna losses over radiation resistance to be greatly reduced and antenna efficiency greatly increased.
- tuning circuit components In order to further increase antenna efficiency, it is important to take care about the tuning circuit components. As a matter of fact, tuning of loop antennas is necessary because of the small bandwidth of this type of antenna. This tuning can be achieved by using varactors.
- each antenna tuning circuit is designed for introducing minimum conductive losses by connecting varactors in parallel.
- first tuning circuit 5a includes a capacitor 52a and a varactor 51 a connected in series and a resistor 53a connected between capacitor 52a and varactor 51a on one side and to a determined potential V A on the other side.
- Resistor 53a supplies varactor 51a with a constant tuning voltage during radio reception, the varactor capacitance being changed with this tuning voltage. Therefore, any particular reception frequency of the antenna requires a different varactor capacitance that is tuned by this tuning voltage.
- Voltage V A is determined by way of conventional means, for example with a binary search algorithm.
- Second tuning circuit 5b is of the same type as tuning circuit 5a. It includes a capacitor 52b and a varactor 51 b connected in series and a resistor 53b connected between capacitor 52b and varactor 51 b on one side and to a determined potential V B on the other side. Resistor 53b supplies varactor 51 b with a constant tuning voltage during radio reception, the varactor capacitance being changed with this tuning voltage. Therefore, any particular reception frequency of the antenna requires a different varactor capacitance that is tuned by this tuning voltage. Voltage V B is also determined by way of conventional means, for example with a binary search algorithm.
- each tuning circuit can include two varactors, instead of one varactor and one capacitor, connected in series but in opposite polarisation in order to optimise the behaviour of these tuning circuits.
- both varactors 51 a and 51 b are connected in an "anti" parallel way, being then in opposite polarisation. Even with asymmetry of both tuning circuits, it is nevertheless a preferred solution because it introduces fewer losses and requires fewer components than symmetrical tuning circuits that comprise each two varactors in series and in opposite polarisation.
- tuning circuits 5a and 5b are preferably provided with a capacitor C T for adjusting their tuning range, which is connected between capacitor 52a and varactor 51a of first tuning circuit 5a on the one side, and between varactor 51 b and capacitor 52b of second tuning circuit 5b on the other side.
- the loop antennas are preferably rectangular or so-called opened O-shaped.
- both loop antennas have the same shape in order to preserve symmetry.
- any other loop antenna shape can be used as long as it fits into wristband portions.
- Both antennas operate preferably in the frequency band from 88 to 108 MHz using the radio data transmission system.
- the wireless instrument is preferably a wristwatch.
