Embodiment
Figure 1 shows that according to can the reset structural representation (plane that X-axis and Y-axis constitute of formula antenna, the plane of one embodiment of the invention, the plane that-X-axis and Y-axis constitute), Figure 2 shows that in order to the plane of the key diagram 1 perspective structure schematic diagram (the three-dimensional space figure of XYZ) of formula antenna on vertical plane of can resetting.Please be simultaneously with reference to Fig. 1 and Fig. 2, the plane formula antenna 100 of can resetting comprises a substrate 110, a metal level 120, a main antenna 130, an auxiliary antenna 140 and a switches set 150.More clearly, Fig. 2 can reset formula antenna 100 on three-dimensional space for the plane, the relative perspective diagram of each member on the substrate 110 on vertical plane.
Please continue with reference to Fig. 1 and Fig. 2, substrate 110 comprises a first surface 111 and a second surface 112.Main antenna 130 comprises one first actuator (driving element), 131 and 1 second actuator 132.Auxiliary antenna 140 comprises that one first points to part (director) 141, one second sensing part 142, one the 3rd sensing part 143 and one the 4th sensing part 144.Switches set 150 comprises one first switch 151 and a second switch 152.Wherein, metal level 120 is arranged on the first surface 111 of substrate 110.Main antenna 130 and the symmetrical member of auxiliary antenna 140 each self-forming, and be distributed in the first surface 111 and second surface 112 of substrate 110.150 of switches set are arranged on the substrate 110.
In practical application, main antenna 130 can for example be dipole antenna (dipole antenna).Present embodiment is to be that example is enumerated main antenna 130 with the dipole antenna, so first actuator 131 of main antenna 130 and the shape of second actuator 132 present L shaped respectively, and have both arms separately, for example: first actuator 131 has a first arm 131a and one second arm 131b, and second actuator 132 has a first arm 132a and one second arm 132b.
As shown in Figure 1, when first actuator 131 and 132 of second actuators were not taken apart, it was to be close to two identical members.Yet, on physical arrangements, first actuator 131 and second actuator 132 are configured in the first surface 111 and second surface 112 of substrate 110 respectively, it should be noted that, among Fig. 1 the relative space relation of first actuator 131 and first surface 111 be with-X-axis is expressed with Y-axis, and the relative space relation of second actuator 132 and second surface 112 is to express with X-axis and Y-axis.In addition, as shown in Figure 2, the first arm 131a and the 132a of first actuator 131 and second actuator 132 are overlapped on vertical plane, and the second arm 131b of first actuator 131 and second actuator 132 and 132b are symmetrical in a direction DR (Y-axis).In addition, be configured in first actuator 131 of first surface 111, its first arm 131a is extended by metal level 120 to grow.Whereby, main antenna 130 can be towards direction DR, also just perpendicular to the direction of the second arm 131b or the second arm 132b of second actuator 132 of first actuator 131, to give off maximum energy.
On the other hand, at the words of auxiliary antenna 140 with switches set 150, in the auxiliary antenna 140 first points to part 141 and second and points to the first surface 111 that part 142 is arranged on substrate 110, and first points to the second arm 131b of part 141 with respect to first actuator 131.In addition, first switch 151 in the switches set 150 is arranged on the first surface 111 of substrate 110, and is electrically connected between the first sensing part 141 and the second sensing part 142.Whereby, whether the conducting of first switch 151 points to the annexation that part 141 and second points to part 142 with variable first.
Relatively, the 3rd in the auxiliary antenna 140 points to part 143 and the 4th and points to the second surface 112 that part 144 is arranged on substrate 110, and the 3rd points to the second arm 132b of part 143 with respect to second actuator 132.In addition, the second switch 152 in the switches set 150 is arranged on the second surface 112 of substrate 110, and is electrically connected between the 3rd sensing part 143 and the 4th sensing part 144.Therefore, whether the conducting of second switch 152 points to the annexation that part 143 and the 4th points to part 144 with the variable the 3rd.
It should be noted that, along with first to fourth change of pointing to the annexation of part 141～144, also will produce different coupling effects between main antenna 130 and the auxiliary antenna 140, and then cause the plane formula antenna 100 of can resetting to be created in wave beam on a certain specific direction.For instance, Figure 3 shows that according to can the reset beam pattern of formula antenna of the plane of one embodiment of the invention and switch schematic diagram, please be simultaneously with reference to Fig. 2 and Fig. 3.When first switch 151 and second switch 152 all not conductings (turn off), by the coupling effect between main antenna 130 and the auxiliary antenna 140, the plane formula antenna 100 of can resetting will produce a wave beam, and the direction of this beam position (also can regard the scanning direction as) is direction DR, just as shown in Figure 3, this moment, can the reset deviation angle of the wave beam that formula antenna 100 produced of plane was 0 degree.
In addition, when first switch, 151 conductings (turn on) and second switch 152 not conductings (turn off), the plane formula antenna 100 of can resetting also will produce a wave beam, and the direction of this beam position promptly can be turned right and be departed from direction DR one predetermined angle, for example: shown in Figure 3, this moment plane deviation angle 45 degree approximately slightly of the wave beam that formula antenna 100 produced of can resetting.Relatively, when 151 not conductings of first switch and second switch 152 conductings, the plane formula antenna 100 of can resetting also will produce a wave beam, and the direction of this beam position can be turned left and be departed from direction DR one predetermined angle, for example: shown in Figure 3, this moment the plane deviation angle degree approximately slightly-45 of the wave beam that formula antenna 100 produced of can resetting.Moreover when first switch 151 and second switch 152 simultaneously all during conducting, the ceiling capacity direction that this moment, main antenna 130 was given off will be towards the direction perpendicular to direction DR, and radiate along the both sides of main antenna 130.
In other words, 100 need of formula antenna can be reset by the controlling of first switch 151 and second switch 152, with regard to the direction (or regarding the scanning direction as) of variable beam position in the plane.In view of the above, when formula antenna 100 can be reset when being applied in portable electric device in the plane, for example: mobile phone, notebook computer (Notebook), global positioning system (Global Positioning System, GPS), super removable computer (Ultra MobilePC, UMPC), net book (Network Linkable Notebook, Netbook), intelligence this (Smartbook) etc., portable electric device can be according to the power of signal source (for example satellite send signal), dynamically (adaptively) adjusts the conducting state of first switch 151 and second switch 152, and then sensing scans the best/the strongest signal.And those skilled in the art, the formula antenna 100 of also can be able to being reset in this plane is applied in WLAN, and (bridger of Wireless Local Area Network～WLAN) is (on the Accesspoint～AP), on the perhaps intelligent base station (Smart Base-station), through suitable design, also can have the function of pointing to the signal that scans the best/the strongest.And embodiments of the invention are all done explanation with portable electric device, but the category of being protected is not subject to the limits.
For instance, in the time of under portable electric device is in a screen (for example: overpass or crowded residential area), if come received signal (field pattern of its antenna is changeless form) with general traditional gps antenna, traditional gps antenna can be in response to the difference of the residing position of portable electric device, and the signal that causes via satellite to be launched by arround complex environment influence, and then have influence on the performance of GPS, as the accuracy of location required time and location.Yet, formula antenna 100 can be reset in the described plane of present embodiment but can be by the mode in dynamic beam sweep signal source, point to (direction) and receive gps signal to best sense, in other words, when the signal of certain direction is more weak, therefore then go received signal, the external environment influence degree can be dropped to minimumly, and then improve required time and the accuracy of GPS on the location from another direction.
In addition, therefore the framework that formula antenna 100 has panelized owing to can reset in the plane can be set directly on mechanism's part of portable electric device, for example: mobile phone back of the body lid or battery back of the body lid etc., or directly on the PCB substrate, be configured (layout).In view of the above, portable electric device also can because of the plane can reset formula antenna 100 panelized and have microminiaturized advantage.On the other hand, 100 need of formula antenna controlling owing to can reset in the plane by first switch 151 and second switch 152, with regard to the direction of variable beam position, so the plane formula antenna 100 of can resetting also can reduce the complexity of portable electric device on system realizes.
Please continue with reference to Fig. 1 and Fig. 2, with the enforcement kenel of first to fourth sensing part 141～144 in practical application in the explanation auxiliary antenna 140.In the present embodiment, first points to part 141 and the 3rd points to part 143 be symmetrical in direction DR on vertical plane, and second points to part 142 and the 4th sensing part 144 is symmetrical in direction DR on vertical plane.
On electrically connecting, the first sensing part 141 and the 3rd 143 of parts of sensing also can be done by a guide hole and be electrical connected.For example, the plane formula antenna 100 of can resetting also comprises one first guide hole 160, and first guide hole 160 runs through substrate 110, first and point to part 141 and point to part 143 with the 3rd, points to part 141 and the second sensing part 143 is electrical connected to cause first.On the other hand, the first sensing part 141 and the 3rd points to part 143 and can be electrically connected to second separately and point to part 142 and the 4th sensing part 144 respectively by first switch 151 and second switch 152 again.Therefore, concerning auxiliary antenna 140, the first sensing part 141 and three points to parts 143 and just is equivalent to a primary radiation arm, and the second sensing part 142 and the 4th points to part 144 with regard to suitable one a left radiation arm and a right radiation arm.
On physical arrangements, left radiation arm and right radiation arm can present the staged arrangement with respect to the arrangement of primary radiation arm.For example: in the present embodiment, it is to present downward staged to arrange that the first sensing part 141 and second points to part 142.Yet this area has knows that usually the knowledgeable also can point to part 142 with the first sensing part 141 and second according to design and change to the staged arrangement that makes progress.In addition, when presenting the staged arrangement, first spacing of pointing between the part 141 and the second sensing part 142 can be between 1 to 15 millimeter.Moreover the left radiation arm of auxiliary antenna 140 and right radiation arm also can present the horizontal arrangement with respect to the arrangement of primary radiation arm.That is first to fourth point to part 141～144 and can be arranged on simultaneously on the same horizontal line.
On entity design, the primary radiation arm of auxiliary antenna 140, right radiation arm and the length of left radiation arm is rough equates.That is to say, first point to that part 141 points to part 143 additions with the 3rd and length, approximately be equal to second length of pointing to part 142 or the 4th sensing part 144.In addition, auxiliary antenna 140 with respect to the second arm 132b addition of the second arm 131b of main antenna 130, the first actuators 131 and second actuator 132 and length, point to the length that part 141 or the 3rd points to part 143 greater than first.
In order to strengthen the quality of radiofrequency signal in transmission, the plane formula antenna 100 of can resetting comprises that also (for example: second guide hole 231～234), and metal level 120 comprises a groove 240 with a plurality of second guide holes for a feed-in cabling 170, one first path cabling 181, one second path cabling 182, one the 3rd switch to the 6th switch 191～194, one first reflecting element 210, one second reflecting element 220.Wherein, the length of the first path cabling 181 is greater than the length of the second path cabling 182, wherein feed-in cabling 170 can be regarded can the reset feed-in district of formula antenna 100, this plane as, and feed-in cabling 170 is electrically connected to main antenna 130,120 of metal levels can be regarded the access area as, and metal level 120 electrically connects with the ground plane of system again.
At this, feed-in cabling 170, the first path cabling 181, the second path cabling 182 and the 3rd to the 6th switch 191～194 all are arranged on the second surface 112 of substrate 110.The first path cabling 181 can be electrically connected between second actuator 132 and the feed-in cabling 170 by the 3rd switch 191 and the 4th switch 192, and the second path cabling 182 can be electrically connected between second actuator 132 and the feed-in cabling 170 by the 5th switch 193 and the 6th switch 194.In addition, the conducting state of the 3rd to the 6th switch 191～194 can be along with first to fourth change of pointing to the annexation of part 141～144, the change of first switch 151 and the conducting state of second switch 152 just, and produce corresponding the variation.More clearly, the Antenna Design of present embodiment can be according to the conducting state of above-mentioned switch room, dynamically adjust the path (from feed-in cabling 170, the first path cabling 181, the second path cabling 182, main antenna 130, auxiliary antenna 140) that signal transmits, so as to keeping a specific frequency of operation, this frequency can be in the frequency band or certain set frequency, based on the design that different switches switch of arranging in pairs or groups of above-mentioned adjustable path, can avoid descending, so can make the operation of portable electric device more stable because of the frequency of operation drift causes performance for wireless communications.
For instance, when first switch 151 and second switch 152 one of them conducting, just when the primary radiation arm of auxiliary antenna 140 is electrically connected to its left radiation arm or right radiation arm, the 3rd switch 191 and the 4th switch 192 are all with not conducting, but the 5th switch 193 and the 6th switch 194 are all with conducting.At this moment, the plane received signals of formula antenna 100 of can resetting can be sent to feed-in cabling 170 by the second short path cabling 182.
Relatively, when first switch 151 and second switch 152 simultaneously during not conducting, just when the primary radiation arm of auxiliary antenna 140 is not electrically connected to its left radiation arm or right radiation arm, the 3rd switch 191 and the 4th switch 192 are all with conducting, but the 5th switch 193 and the 6th switch 194 are all with not conducting.At this moment, but the received signals of plane structure formula antenna 100 can be sent to feed-in cabling 170 by the first long path cabling 181.
Please continue with reference to Fig. 1 and Fig. 2, first reflecting element 210 and second reflecting element 220 are arranged on the second surface 112 of substrate 110, and be arranged in the both sides of the first arm 132a of second actuator 132, and in the present embodiment, first reflecting element 210 and second reflecting element 220 present strip formula (strip).In addition, first reflecting element 210 and second reflecting element, 220 upright projections are on the first surface 111 of substrate 110 time, and the projection nucleus of these reflecting elements is (the most close second arm 131 places) around the top margin of metal level 120.Moreover, the peripheral shape of metal level 120 shape general and substrate 110 is similar, and become rectilinear polygon (for example rectangle), therefore, first reflecting element 210 and second reflecting element 220 also can become linearity, when we in Fig. 1 from the angle of overlooking (top view, from+Z past-direction of Z), wherein above-mentioned so-called periphery comprises top margin, side and base.And in the present embodiment, in order to make this plane formula antenna of can resetting have wider beam position angle, make the top margin of metal level 120 present the circular-arc of raised type, just the top margin of metal level 120 is toward the outside protrusion of DR direction (promptly+Y direction), and the curve of evagination presents circular-arc, so first reflecting element 210 and second reflecting element 220 are also accordingly along the top margin of metal level 120 and present circular-arc.Whereby, first reflecting element 210 and second reflecting element 220 will help to produce preferable beam position degree.In addition, can increase can reset wave beam that formula antenna 100 produced of plane and depart from the angular dimension of direction DR because have circular-arc metal level 120, first reflecting element 210 and second reflecting element 220.
Certainly, first reflecting element 210 and second reflecting element 220 are not to be confined to the strip formula, and these reflecting elements can present arbitrary polygon shape (polygon pattern) on substrate 110, but are noted that these reflecting elements can not touch feed-in cabling 170.And in Fig. 4 and Fig. 5, then shown typically these reflecting elements have difform enforcement aspect.Wherein, these reflecting elements of Fig. 4 extend a small distance toward the opposite direction plane formula ground of DR direction, then extend a bigger distance among Fig. 5.Therefore, more can make this plane formula antenna 100 of can resetting have wider beam position angle.
Please in the lump with reference to Fig. 1 and Fig. 3, when top margin, first reflecting element 210 and second reflecting element 220 of metal level 120 all are in line shape, the plane can reset angle that wave beam that formula antenna 100 produced departs from direction DR be about each 30 °; If the top margin of metal level 120, when first reflecting element 210 all becomes circular-arc with second reflecting element 220, its deviation angle approximately slightly about respectively 45 °.Hence one can see that, and the formula antenna 100 of can resetting of the plane after the improvement has wider beam scanning angle.
Moreover, first reflecting element 210 and second reflecting element 220 be the energy in order to be given off by second actuator 132 on the reflection second surface 112 mainly, 120 of metal levels mainly are the energy that is given off by first actuator 131 in order on the reflection first surface 110, but because the radiation of energy from all directions and be not easy to be controlled, therefore, first reflecting element 210 and second reflecting element 220 also may reflex to the energy that is produced on the first surface 110, metal level 120 also may reflex to the energy that is produced on the second surface 112, so some energy is break-through to be crossed substrate and exhales toward opposite direction (Y direction) radiation of DR, and the signal that these lose also can exert an influence to the usefulness of antenna integral body to a certain extent.
In order to drop to above-mentioned influence minimum, it should be noted that, present embodiment can additionally dispose a plurality of guide holes again, as Fig. 1 and shown in Figure 2, second guide hole (via) 231～234 runs through metal level 120, the substrate 110 and first reflecting element 210, or run through metal level 120, the substrate 110 and second reflecting element 220, also can make the plane formula antenna 100 of can resetting have wider beam scanning angle and better beam position degree whereby, because these guide holes also have the same effect with these reflecting elements and metal level, the above-mentioned portion of energy that substrate is crossed in break-through can be reflected the transmitting-receiving effect of the integrated antenna that therefore is improved.Wherein, the quantity of guide hole is not limited only to 4, can adjust accordingly according to the demand of integrated antenna design, but also must consider the factor of cost, and its relative position also can be elaborately planned according to those skilled in the art.Therefore, on electrically connecting, first reflecting element 210 or second reflecting element 220 can be electrically connected to metal level 120 by second guide hole 231～234.On the other hand, the first arm 131a of first actuator 131 is arranged on the central authorities of groove 240, strengthens the matching degree of main antenna 130 whereby.
