Definitions
- the present invention relates to the field of antennas.
- the present invention relates to the field antennas intended for the broadcasting of broadband services, particularly in the field of UWB (Ultra Wide Band or Ultra Large Band), but also for wireless networks, such as WLAN (Wireless Lan) and WIFI (registered trademark) (Wireless Fidelity), as well as in the field multiband cellular telecommunications.
- UWB Ultra Wide Band or Ultra Large Band
- wireless networks such as WLAN (Wireless Lan) and WIFI (registered trademark) (Wireless Fidelity), as well as in the field multiband cellular telecommunications.
- UWB A new system, called UWB, that allows you to reuse frequency bands already allocated for other applications the subject of developments for telecommunications applications civil.
- the UWB transmits at very low level (of the order of noise) a coherent but spread signal over a very wide band of frequencies (hence the name "Ultra Wide Band "). Consistency is ensured by pulse coding Gaussian and it is essential that every element of the chain of transmission, including the antenna, has the most transfer function possible neutral over the entire width of the strip (typically 3 to 10 GHz) so that the receiving system is able to recover the useful signal in the middle of the noise.
- the antenna behaves like a bandpass filter that conditions the performance of the complete system.
- the main object of the present invention is to remedy this situation by proposing a new antenna to answer these specifications, that is to say an antenna able to transform the energy incident energy radiated on a very wide band of frequency (Fmax / Fmin> 5).
- Another auxiliary object of the present invention is to propose an antenna whose geometry remains small vis-à-vis of the wavelength.
- Yet another auxiliary object of the present invention is to propose an antenna that can easily be integrated on a map type PCMCIA or PCB (ie Printed Circuit or Printed Circuit) Circuit Board "in English), for example in the form of a structure coplanar engraved on one side of an electronic substrate, thus facilitating the subsequent integration of active elements.
- a map type PCMCIA or PCB ie Printed Circuit or Printed Circuit
- the inventors have indeed determined that it is essential in the of the present invention that the border of the directed ground plane towards the monopoly is not straight to reach a broad band bandwidth.
- FIG. 3 shows an antenna according to the present invention. invention comprising a support 10 of dielectric material which carries a monopoly 100 and a ground plane 200.
- the support 10 can be made of any suitable material and can have all appropriate geometry and dimensions.
- It is preferably of rectangular or square contour.
- the monopoly 100 and the ground plane 200 are coplanar. They are made in printed technology and engraving on one side of support 10.
- the support 10 has dimensions of the order of 57.5 mm x 47 mm and a thickness of the order 1.5mm.
- monopoly 100 and the ground plane 200 have symmetry by report to an O-O plan.
- This O-O plane passes through the central axis of a line excitation 110.
- the excitation line 110 is formed of a straight ribbon 112 of constant width, delimited by two lateral edges 114, 115 parallel between them and parallel to the plane O-O.
- the excitation line 110 extends so, from the middle of one of the edges of the wafer, perpendicular to this edge, towards the center of the support 10.
- Monopoly 100 is connected to the inner end of the line 110. It has a general shape flared away from the plane 200.
- the contour of monopoly 100 directed towards the ground plane 200 may have a continuous curvature. However preferably this outline is delimited by a series of successive rectilinear sections of which the inclination with respect to the plane O-O increases away from the plane of 200.
- monopoly 100 can thus be be delimited by three successive sections 120, 122 and 124 having respective inclinations of the order of 10 °, 30 ° and 45 ° and lengths respective of the order of 17 mm, 7 mm and 20 mm.
- Monopoly 100 is otherwise limited, opposite the excitation line 110, by an edge rectilinear 130, transverse to the plane O-O, for example a length of the order of 37 mm.
- Monopoly 100 thus formed has the general form of a plane cone with multiple slopes.
- the 200 ground plan includes two blocks 210, 220 respectively located on either side of the line 110, being separated therefrom.
- the ground plane 200 has a border 230 directed to monopoly 100 which is not completely straight.
- the curvature of this border 230 may be continuous.
- this border 230 is delimited by a series of successive rectilinear sections. More precisely according to the embodiment shown in FIG. each block 210, 220 is delimited, starting from the edge of the support 10 on which opens the supply line 110, by an internal section rectilinear 240, parallel to the plane O-O, of the same length as the line 110, and a rectilinear outer portion 242, also parallel to the O-O plane, of a length greater than section 240, typically of the order of twice the latter, for example of the order 23.5mm.
- the two sections 240, 242 are connected by a plurality of sections 244, 246, 247, 248, which in combination define a shape convex, for each pavement, towards the monopoly 100. More precisely according to the particular embodiment and not limiting illustrated in FIG. 3, the section 244 extends the section 242 and converges towards the O-O plane towards the monopoly 100.
- the three sections 246, 247 and 248 succeed one another from the internal section 240. They diverge, with gradually increasing angles, compared on the O-O plane, in connection with the monopoly 100.
- the sections 244 and 248 come together at a point 249 which is the point of the plan of mass 200 farthest from the edge of the support 10 on which opens the power line 110.
- the overall width of the ground plane 200 is substantially identical to the most wide monopoly 100, at the edge 130.
- tip 249 of the ground plane 200 is located substantially next to the outer quarter of the width of the development of the monopoly 100.
- the dielectric support 10 Between the monopoly 100 and the ground plane 200, the dielectric support 10.
- the geometry of the plane of mass 200 and that of the monopoly 100 are preferably adapted so that the monopoly defines a impedance at least substantially constant along its profile.
- Monopoly 100, power line 110 and ground plane 200 are advantageously made in printed circuit technology.
- the geometry of the plane of mass 200 and that of monopoly 100 are adapted to minimize the sizes and to optimize the shapes of the ground plane 200 as well as that of the coplanar monopoly 100, so as to guarantee excitation by a line 110 coplanar characteristic impedance typical of telecommunications applications (in the range 50 ⁇ - 70 ⁇ ) on the widest possible bandwidth.
- FIG. 4 shows a variant embodiment according to which monopoly 100, of polygonal shape, is asymmetrical by relative to the plane O-O, while the plane of mass 200 remains symmetrical relative to this plane O-O.
- Monopoly 100 is delimited, starting from feed line 110, by two rectilinear sections 140, 142 which diverge from the O-O plane away from the ground plane 200, at different angles, two sections 144, 146 parallel between them and parallel to the O-O plane which extend respectively the two sections 140, 142, and the aforementioned end edge 130.
- Each block 210, 220 of the ground plane 200 is itself delimited by a internal generator 240, an external generator 242, parallel between they are parallel to the plane O-O, (the internal generator 240 having a length substantially identical to the feed line 110), a extreme stretch 250 rectilinear and perpendicular to the plane O-O, connected to the internal generator 240 and two successive rectilinear sections 252 and 254, which connect the end portion 250 and the external generator 242, which sections 252 and 254 diverge from the monopoly 100 in away from the O-O plane
- the outer sections 242 are shorter than the sections 240.
- the sections 250, 252 and 254 define in combination a convex form towards the monopoly 100.
- the overall width of the ground plane 200, considered perpendicular to the plane O-O is greater than the width of monopoly 100.
- FIG. 5 represents an antenna variant according to the present invention which differs from that illustrated in Figure 4 by the fact that according to Figure 5, each inclined section 140, 142 of the monopoly 100, is itself divided into two sections 1400, 1402 and 1420, 1422.
- FIG. 6 shows another variant of antenna according to the present invention, which is different from that illustrated on FIG. 5 in that according to FIG. 6, the directed edge of the plane of mass directed towards the monopoly defines a concave border, and not convex, in the direction of monopoly 100.
- This concave edge is defined by a section 250 perpendicular to the plane O-O, connected to the section 240 and extended by two auxiliary sections 256, 258 to the external section 242.
- the first section 256 diverges with respect to O-O plane towards the monopoly 100.
- the second section 258 is perpendicular to the plane O-O and joins the outer section 242.
- FIGS. 7 and 8 show two variants of FIG. and 6, which are distinguished from these by the fact that the ground plane 200 has grooves or "corrugations" 260.

According to FIGS. 7 and 8, the grooves 260 are equidistant two to two. Their length decreases in approximation of the monopoly 100.
- Such grooves 260 make it possible to lower the frequency minimum operating cost of the structure, which increases compactness for a given frequency band. They also allow to stop the electric currents that would tend to "run away" to the back of the ground plane 200 causing radiation interference or parasitic coupling with the power supply.
- FIG. 9 shows a variant of embodiment distinguishes from Figure 5 by the fact that monopoly 100 includes grooves 160. More precisely according to the particular embodiment and non-limiting example shown in Figure 9, the monopoly 100 is provided with three rectilinear grooves 162, 163 and 164, parallel to each other and perpendicular to the O-O plane, which lead to the outer sections 144, 146. According to Figure 9 the grooves 160 are equidistant two to two. Their length increases closer to the ground plane 200.
- Such grooves 160 also make it possible to lower the minimum frequency of operation of the structure.
- FIG. 10 shows another variant embodiment which differs from FIG. 4 in that a short circuit 170 connects the monopoly 100 and the ground plane 200.
- the short circuit 170 is here formed of a rectilinear ribbon parallel to the plane O-O, which connects the section 142 and section 250.
- FIG. 11 illustrates another variant of embodiment is distinguished from Figure 6 by the presence of slotted lines 174, 178 in monopoly 100 and slot lines 274, 278 in the plane of mass 200.
- the slotted lines 174, 178 open onto the sections 144.
- the slotted line 174 comprises a rectilinear section 175 perpendicular to the plane O-O, which leads to a section 144, a rectilinear section 176 parallel to the plane O-O and a rectilinear section 177 perpendicular to the plane O-O, of length less than section 175.
- the three sections 175, 176 and 177 globally define a configuration in U.
- the slit line 178 comprises a rectilinear section 179 perpendicular to the plane O-O, which leads to the second section 144, and a rectilinear section 180 parallel to the plane O-O, directed towards the section 130.
- the two sections 179 and 180 globally define a configuration in L.
- the slot lines 274, 278 provided in the 200 ground plane have a geometry similar to that of the lines with slots 174, 178 provided in monopoly 100.
- the slot line 274 comprises a straight section 275 perpendicular to the plane O-O, which leads to a section 242, a rectilinear section 276 parallel to the plane O-O and a rectilinear section 277 perpendicular to the plane O-O, of length less than section 275.
- the three sections 275, 276 and 277 globally define a configuration in U.
- the slit line 278 comprises a straight section 279 perpendicular to the plane O-O, which leads to the second section 242, and a rectilinear section 280 parallel to the plane O-O, directed towards the monopoly 100.
- the two sections 279 and 280 globally define a configuration in L.
- the second sections 176, 276 are directed to the opposite of section 130 away from the section 175, 275 which leads respectively to the outside of the monopoly 100 at the level of the section 144 and at the outside of the ground plane 200 at level of section 242.
- FIG. 12 also illustrates another variant which differs from FIG. 3 in that slots, rings or holes are inserted in the monopoly 100 or in the mass plane 200. Such slots, rings or holes allow to advantageously introduce secondary modes of resonance in the structure.
- FIG. 13 shows the adaptation curve of the antenna shown in FIG. 3, more precisely the ratio of standing waves (ROS) as a function of frequency.
- ROS standing waves
- Such an antenna of compact dimensions since they are of the order of 47mmx37mmx1,5mm ensures operation ultra wide bands from 1.5 to more than 11GHz, a ratio of maximum frequency and the minimum frequency greater than 7.
