Figure 1 shows that the structural representation (plane that X-axis and Y-axis consist of according to the Flat plane reconfigurable antenna of one embodiment of the invention, the plane that-X-axis and Y-axis consist of), Figure 2 shows that the perspective structure schematic diagram (the three-dimensional space figure of XYZ) of Flat plane reconfigurable antenna on vertical plane in order to key diagram 1.Please be simultaneously with reference to Fig. 1 and Fig. 2, Flat plane reconfigurable antenna 100 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 be Flat plane reconfigurable antenna 100 on three-dimensional space, the relative perspective diagram of each member on 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 auxiliary antenna 140 symmetrical members of 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 substrate 110.
In practical application, main antenna 130 can be for example dipole antenna (dipole antenna).The present embodiment is to enumerate main antenna 130 as an example of dipole antenna example, therefore the first actuator 131 of main antenna 130 and the shape of the second actuator 132 present respectively L shaped, and have separately both arms, for example: the first actuator 131 has one first arm 131a and one second arm 131b, and the second actuator 132 has one first arm 132a and one second arm 132b.
As shown in Figure 1, when the first actuator 131 and 132 of the second actuators were not taken apart, it was to be close to two identical members.Yet, on physical arrangements, the first actuator 131 and the second actuator 132 are configured in respectively the first surface 111 and second surface 112 of substrate 110, it should be noted that, in Fig. 1 the relative space relation of the first actuator 131 and first surface 111 be with-X-axis is expressed with Y-axis, and the relative space relation of the 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 the first actuator 131 and the second actuator 132 are overlapped on vertical plane, and the second arm 131b of the first actuator 131 and the second actuator 132 and 132b are symmetrical in a direction DR (Y-axis).In addition, be configured in the first actuator 131 of first surface 111, its first arm 131a is extended by metal level 120 to be grown.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 the second actuator 132 of the first actuator 131, to give off maximum energy.
On the other hand, for the words of auxiliary antenna 140 with switches set 150, in 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 part 141 with respect to the second arm 131b of the first actuator 131.In addition, the first switch 151 in 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 the first switch 151 points to variable first the annexation that part 141 and second points to part 142.
Relatively, the 3rd in 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 part 143 with respect to the second arm 132b of the second actuator 132.In addition, the second switch 152 in 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 variable the 3rd the annexation that part 143 and the 4th points to part 144.
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 auxiliary antenna 140, and then cause Flat plane reconfigurable antenna 100 to be created in wave beam on a certain specific direction.For instance, Figure 3 shows that the beam pattern switching schematic diagram according to the Flat plane reconfigurable antenna of one embodiment of the invention, please be simultaneously with reference to Fig. 2 and Fig. 3.When the first switch 151 and second switch 152 all not conductings (turn off), by the coupling effect between main antenna 130 and auxiliary antenna 140, Flat plane reconfigurable antenna 100 will produce a wave beam, and the direction of this beam position (also can regard the scanning direction as) is direction DR, namely as shown in Figure 3, this moment the wave beam that Flat plane reconfigurable antenna 100 produces deviation angle be 0 degree.
In addition, when the first switch 151 conductings (turn on) and second switch 152 not conductings (turn off), Flat plane reconfigurable antenna 100 also will produce a wave beam, and the direction of this beam position namely can be turned right and be departed from direction DR one predetermined angle, for example: shown in Figure 3, this moment the wave beam that produces of Flat plane reconfigurable antenna 100 deviation angle 45 degree approximately slightly.Relatively, when the first switch 151 not conductings and second switch 152 conducting, Flat plane reconfigurable antenna 100 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 deviation angle approximately slightly-45 of the wave beam that Flat plane reconfigurable antenna 100 produces was spent.Moreover when the first switch 151 and second switch 152 simultaneously all during conducting, the ceiling capacity direction that this moment, main antenna 130 gave 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 Flat plane reconfigurable antenna are controlled by the first switch 151 and second switch 152, with regard to the direction (or regarding the scanning direction as) of variable beam position.accordingly, when Flat plane reconfigurable antenna 100 is applied in portable electric device, 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 the first switch 151 and second switch 152, and then sensing scans the best/the strongest signal.And those skilled in the art, (bridger of Wireless Local Area Network~WLAN) is (on Accesspoint~AP) also this Flat plane reconfigurable antenna 100 can be applied in WLAN, perhaps on 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 all explain with portable electric device, but the category of protecting 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 quarter), if receive signal (field pattern of its antenna is as changeless form) take general traditional gps antenna, traditional gps antenna can be in response to the difference of the residing position of portable electric device, and cause the signal launched via satellite by arround complex environment affect, and then have influence on the performance of GPS, as the accuracy of location required time and location.Yet, the described Flat plane reconfigurable antenna 100 of the 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 weak, therefore remove to receive signal from another direction, the external environment influence degree can be dropped to minimumly, and then improve required time and the accuracy of GPS on the location.
Therefore in addition, have the framework of panelized due to Flat plane reconfigurable antenna 100, can be set directly on mechanism's part of portable electric device, such as mobile phone back of the body lid or battery back of the body lid etc., or directly be configured (layout) on the PCB substrate.Accordingly, portable electric device also can have because of the panelized of Flat plane reconfigurable antenna 100 microminiaturized advantage.On the other hand, due to 100 need of Flat plane reconfigurable antenna controlling by the first switch 151 and second switch 152, with regard to the direction of variable beam position, so Flat plane reconfigurable antenna 100 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 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 being electrically connected, 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, Flat plane reconfigurable antenna 100 also comprises one first guide hole 160, and the first guide hole 160 runs through substrate 110, the first sensing part 141 and the 3rd points to part 143, is electrical connected to cause the first sensing part 141 and second to point to part 143.On the other hand, the first sensing part 141 and the 3rd points to part 143 and can respectively by the first switch 151 and second switch 152, be electrically connected to separately second and point to part 142 and the 4th sensing part 144 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 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, the first spacing of pointing between 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 horizontal arrangement with respect to the arrangement of primary radiation arm.That is first to fourth point to part 141~144 and can arrange in the same horizontal line simultaneously.
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 the 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 the second actuator 132 and length, point to greater than first the length that part 141 or the 3rd points to part 143.
In order to strengthen the quality of radiofrequency signal in transmission, Flat plane reconfigurable antenna 100 also comprises 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, (for example: the second guide hole 231~234), and metal level 120 comprises a groove 240 to one second reflecting element 220 with a plurality of the second guide holes.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 the feed-in district of this Flat plane reconfigurable antenna 100 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 is electrically connected 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 the second actuator 132 and 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 the second actuator 132 and 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 namely change of the first switch 151 and the conducting state of second switch 152, and produce corresponding the variation.more clearly, the Antenna Design of the present embodiment can be according to the conducting state of above-mentioned switch room, dynamically adjust the path of signal transmission (from feed-in cabling 170, the first path cabling 181, the second path cabling 182, main antenna 130, auxiliary antenna 140), so as to keeping a specific frequency of operation, this frequency can be in a frequency band or certain set frequency, design based on the above-mentioned different switching overs of adjustable path collocation, can avoid descending because the frequency of operation drift causes performance for wireless communications, therefore can make the operation of portable electric device more stable.
For instance, when the first switch 151 and second switch 152 one of them conducting, namely 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 received signal of Flat plane reconfigurable antenna 100 can be sent to feed-in cabling 170 by the second shorter path cabling 182.
Relatively, when the first switch 151 and second switch 152 simultaneously during not conducting, namely 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 signal 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, the first reflecting element 210 and the 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 the second actuator 132, and in the present embodiment, the first reflecting element 210 and the second reflecting element 220 present strip type (strip).In addition, the first reflecting element 210 and the second reflecting element 220 upright projections are on the first surface 111 of substrate 110 time, the projection nucleus of these reflecting elements (the most close second arm 131 places) around the top margin of metal level 120.Moreover, the peripheral shape of metal level 120 is general and shape substrate 110 is similar, and become rectilinear polygon (for example rectangle), therefore, the first reflecting element 210 and the 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 Flat plane reconfigurable antenna have wider beam position angle, make the top margin of metal level 120 present the circular-arc of raised type, namely the top margin of metal level 120 is outwardly toward DR direction (namely+Y-direction), and the curve of evagination presents circular-arc, therefore the first reflecting element 210 and the second reflecting element 220 are also accordingly along the top margin of metal level 120 and present circular-arc.Whereby, the first reflecting element 210 and the second reflecting element 220 will help to produce better beam position degree.In addition, can increase because have circular-arc metal level 120, the first reflecting element 210 and the second reflecting element 220 angular dimension that wave beam that Flat plane reconfigurable antenna 100 produces departs from direction DR.
Certainly, the first reflecting element 210 and the second reflecting element 220 are not to be confined to strip type, these reflecting elements can present arbitrary polygonal (polygon pattern) on substrate 110, but should be noted, these reflecting elements can not touch feed-in cabling 170.And in Fig. 4 and Fig. 5, shown these reflecting elements have difform enforcement aspect typically.Wherein, these reflecting elements of Fig. 4 extend a larger distance toward opposite direction plane formula ground extension one small distance of DR direction in Fig. 5.Therefore, more can make this Flat plane reconfigurable antenna 100 have wider beam position angle.
