The method and apparatus of various exemplary embodiments comprises at least two antennas and a shield according to the present invention.This shield can reduce the near-field interference between the fully close antenna; Reduce the coupling between the fully close antenna; The noise that shielding is produced by system electronics is to the interference of antenna, and the interference of other system, radio and/or external noise source; And the overlay area of each antenna carried out figuration.Near-field interference and off resonance phenomenon can reduce by the position of antenna on shield, type, the directionality of antenna, antenna characteristics, the selected material type of shield and the antenna dividing plate of antenna.The near-field interference source comprises the near field that produced by another fully close antenna etc.The shape of shield and antenna dividing plate can influence the shape of overlay area of each antenna and the overlapping degree of individual antenna overlay area.The virtual sector of overlapping covered formation that different antennae forms.The overlay area of restriction antenna coverage areas and other another antennas overlapping can reduce interference.
Especially, with reference to figure 1-3, Anneta module 10 comprises 14,16 and 18 and shields 12 of three omnidirectional antennas according to an embodiment of the invention.From vertical view Fig. 1, the shape of shield 12 is triangle body basically.Each antenna 14,16 and 18 is arranged on in the triangle summit one basically.Distance between the size of shield 12 and the fixed therefrom antenna can be arranged to reduce the near-field interference between antenna 14,16 and 18.The shape of shield and each antenna can be respectively antenna 14,16 and 18 with respect to the skew of shield and form overlay areas 20,22 and 24, so as arbitrarily the overlay area of antenna basically not with other antenna interference arbitrarily.
Antenna can be any kind and/or formation.The term antenna is not limited to the individual antenna unit, on the contrary, can be set and/or the array that is designed to the antenna element of the mode work that matches.Aerial array can adopt can be to the electronic circuit of handling from the signal of each antenna element, to form a signal that is similar to the signal that antenna is formed that only has an antenna element.The present invention can adopt various types of array antennas, and for example adaptive array, MIMO and other have the antenna of a plurality of antenna elements.For example, in one embodiment, with reference to figure 4, antenna 16 can be the antenna with at least two antenna elements, for example array antenna.The antenna element of antenna 16 can carry out with single radio alternately.In another embodiment, with reference to figure 4, each antenna 14,16 and 18 can have the individual antenna unit, but they each can carry out alternately with single radio, and can collective work as a MIMO antenna.In another embodiment, with reference to figure 2, antenna 16 is one and comprises three independently MIMO antennas of antenna element.Each antenna element of MIMO antenna 16 can be set on the forward face on same triangle summit.Each antenna element can be along the summit face, with suitable distance setting, so that each antenna is with suitable manner work.In another embodiment, with reference to figure 4, the antenna element of MMO antenna 16 can be along the edge setting of triangle body shield 12.Opposite with antenna with individual antenna unit, adopt antenna unit array will need larger sized shield so that hold these antenna unit in feasible mode.As described below, shield can be used for figuration is carried out in the overlay area of antenna, and no matter antenna only has the individual antenna unit still has a plurality of antenna elements.Antenna with a plurality of antenna elements can provide the additional control of the antenna coverage areas except shield.For example, wave beam formation aerial array can combine use with shield.
In addition, on each position of shield, different antenna types can be set.For example, with reference to figure 6, antenna 14 is one and has individual antenna unit omnidirectional antenna, and antenna 16 is adaptive arraies that are made of a plurality of antenna elements, and antenna 18 is the directional antennas with individual antenna unit.The combination of any antenna type can combine use with shield.In addition, each antenna can be operated on the frequency different with the employed frequency of other antennas.In addition, the communication protocol of each antenna use and/or passage can be different.In one embodiment, with reference to figure 6, each antenna 14,16 and 18 all uses identical communication protocol, but the different passages that are to use this agreement to provide.
Related with each antenna is the overlay area.The overlay area is such zone: in this zone, thereby antenna can receive and sends signal or send an enough strong signal that can be received by another equipment.Do not having under the situation about disturbing, the shape of overlay area depends on the type of antenna.For example, the overlay area of omnidirectional antenna is spherical basically.The overlay area of directional antenna is a spherical part basically.Shield can change the shape of overlay area.In one embodiment, with reference to figure 3, antenna 14 is omnidirectional antennas.Do not having under the situation about disturbing, and be set near before the shield 12 at antenna 14, it is circular that the overlay area of antenna 14 is essentially on two dimension.Be provided with antenna 14 near shield 12, antenna 14 overlay areas be reduced to from circle basically cover about 270 degree, shown in figure overlay area 20.In three-dimensional, overlay area 20 shows as the sphere of having removed a wedge.Shield can also limit the overlay area of directional antenna.In another embodiment, with reference to figure 8-10, antenna 14,16 and 18 is directional antennas that the overlay area is approximately 240 degree.Antenna 14,16 and 18 is arranged in the paraboloidal shield 40, the overlay area of antenna is constrained to about 180 degree with secondary lobe, as shown in figure 10.
The stack of two overlay areas of different antennae forms virtual sectors.With reference to figure 3,5,7,10,13,23 and 30, overlay area 20 and 22 stack have formed virtual sectors 26, and overlay area 22 and 24 stack have formed virtual sectors 28, and the stack of overlay area 24 and 20 has formed virtual sectors 30.Virtual sectors is not limited to the overlapping portion of two adjacent basically overlay areas.In one embodiment, with reference to figure 28-30, except that antenna 14,16 and 18, antenna dividing plate 82 and antenna 80 are set at the top of shield 40.In this embodiment, antenna 80 is omnidirectional antennas, and its overlay area shows as a circle 84 in two dimension. Virtual sectors 26,28 and 30 still exists; Yet, overlapping size and the overlay area 20,22 and the 24 identical in fact virtual sectors of also having formed of overlay area 84 and overlay area 20,22 and 24.Client in the overlay area 20 can be served by antenna 14 and/or antenna 80, or the like.In addition, the client in the virtual sectors 26 can be by antenna 14,16 and/or 18 services.Antenna 80 provides any desired purpose or carries out the communication task of any kind.In one embodiment, antenna 80 provides service for the client.In another embodiment, antenna 80 and, other Anneta modules for example, extremely close radio-cell, and the radio-cell that forms the wireless network network communicates.In another embodiment, antenna 80 does not send signal, and only is used for detecting possible noise source or other interference sources.
Virtual sectors can be represented the zone that high interference zone or wireless device are served by an above antenna.For example, with reference to figure 1-3, suppose Anneta module 10 support I.E.E.E 802.11a/b/g wireless communication protocols.On the one hand, will be attached to antenna 14 and be arranged to be operated in identical passage, and may cause the height in the virtual sectors 26 to disturb with 16 radio.The transmission of antenna 14 can potato masher antenna 16 work, vice versa.On the other hand, to be attached to antenna 14 and be arranged to be operated in passage different, that jamming margin is minimum, and can communicate by letter with antenna 14 and/or communicate by letter with antenna 16 at a passage so that be arranged in virtual sectors 26 wireless clients at another passage with 16 radio.In one exemplary embodiment, with reference to figure 1-3, antenna 14,16 and 18 each be operated in the passage different, that jamming margin is minimum.
When antenna 14,16 and 18 is worked simultaneously, Fig. 4,6,8 and 11 shield 12,36,40 and 44 reduce the near-field interference between antenna coupling and/or the antenna respectively, thereby allow antenna to be provided with more closely when not adopting shield each other.The shield that antenna is set like that 12 shown in the image pattern 1 possibility effect aspect the near-field interference that reduces between antenna coupling and/or antenna 14,16 and 18 is relatively poor, because the isolation that shield provides between antenna seldom.
Antenna and/or Anneta module can also be arranged on below the protective cover.With reference to Figure 18, radome 54 can be made by any material that basically work of antenna is not had to disturb, for example foam, plastics, cloth, glass and other any suitable materials.Radome 54 can use with any kind antenna and/or Anneta module.Radome 54 can provide additional function, for example makes antenna and/or Anneta module be easy to install.Radome 54 can be fixed on the mounting base 56, to form an Anneta module that can be applied in the various environment.Except radome 54, mounting base 56 can be used to fix up an aerial wire and/or Anneta module.
As for the many antenna elements that form MIMO (multiple-input and multiple-output) antenna, the MIMO antenna comprises at least two antenna elements usually, and these antenna unit and same radio are mutual, and work in the mode that matches.As mentioned above, with reference to figure 4, each antenna 14,16 and 18 can have the individual antenna unit, but they can be alternately together, and works in the mode that matches, to form a MIMO antenna.The individual antenna that comprises a MIMO antenna can be the antenna of any kind, for example omnidirectional, orientation, paster, whiplike, spiral and Yagi spark gap.Comprise the antenna of MIMO antenna can be only as transmitting antenna, only as reception antenna or as send/receive antenna.Only as send, only as receiving and all can being used for forming a MIMO antenna as any combination of send/receive antenna.In one exemplary embodiment, with reference to figure 4, antenna 14 and 18 sends and receives, and antenna 16 only receives.In another embodiment, with reference to Figure 25, antenna 70 and 76 sends and receives, and antenna 72 only receives.The signal that antenna 14,16 and 18 receives and sends can be any type of, and independent or combining form is so that reception and/or transmission in the raising overlay area.
Shield can be supported any amount of MIMO antenna.For example, with reference to Figure 25, in a kind of situation, antenna 70,72 and 76 each all only have an antenna element, any two antennas can form a MIMO antenna.In one exemplary embodiment, antenna 70,72 form one with the mutual MIMO antenna of first radio, and the antenna 76 and second radio are mutual.In another embodiment, antenna 72 and 76 form one with the mutual MIMO antenna of first radio, and the antenna 70 and second radio are mutual.In the 3rd embodiment, antenna 70,72 and 76 forms a MIMO antenna, and mutual with same radio.The quantity that increases the individual unit antenna related with shield can increase the quantity that may make up that forms the MIMO antenna.For example, with reference to Figure 24, any two antennas of selecting from antenna sets 68,70,72,74,76 and 78 can be used as a MIMO antenna, and carry out alternately with radio.In one embodiment, antenna 68 and 76 is worked as a MIMO antenna, and mutual with first radio.Antenna also can be used as the MIMO antenna to 70,78 and 72,74, and each is to mutual with second, third radio respectively.Among this embodiment, antenna is to being provided with mutual vertically.
In another embodiment, with reference to figure 26-27, any two antennas can be used for forming a MIMO antenna.In one embodiment, with reference to Figure 24, antenna to 68 and 70,72 and 74,76 and 78 each to forming the MIMO antenna, and mutual with first, second, third radio respectively.In another embodiment, antenna forms the MIMO antenna to 68 and 74,70 and 76,72 and 78.Plural antenna can be operated in together, forms the MIMO antenna.In one exemplary embodiment, with reference to Figure 24, antenna 68,72 and 76 is as a MIMO antenna job, and antenna 70,72 and 74 is as another MIMO antenna work.In this embodiment, each antenna in each MIMO combination is mutually orthogonal.Antenna shown in Figure 26-27 can also per three be divided into one group, forms isolated M IMO antenna.In one embodiment, antenna 68,72 and 76 forms a MIMO antenna, and antenna 70,74 and 78 forms another MIMO antenna.Three above antennas can form a MIMO antenna.Each antenna that is used to form the MIMO antenna can have at least a in the mode of operation that sends and receive, only sends and only receive.
Refer again to Figure 25, in a kind of situation, each antenna has can be as at least two antenna elements of MIMO antenna work, and each antenna 70,72 and 76 can be worked as a MIMO antenna separately, and mutual with radio separately.
As for shield, as mentioned above, shield can reduce coupling and/or the near-field interference between the fully close antenna, and the noise that the shielding harness electronic equipment produces is to the interference of antenna, and figuration is carried out in the overlay area of each antenna.With reference to figure 4, when the distance between the antenna 64 during less than about twice of the wavelength of operating frequency of antenna, antenna can be considered to be provided with fully closely each other.Utilize shield to reduce interference between antennas, improved the performance of antenna, and reduce needed distance between antenna, to reach other performance of level of an expectation.The shape of some shield near-field interference and/or coupling best and that reduce between the fully close antenna adapt.For example, with reference to figure 1, antenna 14,16 and 18 is arranged linearly, does not almost have shield to isolate between them.When combining with aerial position, the shape of shield may not stop the near-field interference between the antenna.Apex configuration the shape of shield 12 of antenna be very suitable for figuration is carried out in the overlay area, but be unsuitable for reducing near-field interference and/or coupling between the antenna.
With reference to figure 1, near-field interference between the antenna of Anneta module 10 and/or coupling can be by making antenna farther minimizing the in interval each other, yet, a distance that needs between the antenna is so that the substantial of near-field interference and/or coupling reduces, and this distance may make that the antenna of Anneta module each other can not be fully close.Shield 12 is used to reduce near-field interference and/or coupling between the antenna by changing aerial position with respect to antenna.With reference to figure 4, the side that antenna 12,14 and 16 is arranged on shield 12 is present between the antenna a real part of shield.Shield between the antenna can stop and/or reduce near-field interference and/or the coupling between the antenna, thereby reduces fully close interference between antennas.Shield 36,40,44,48 and 52 among Fig. 6,8,11,14 and 16 has reduced near-field interference and/or the coupling between the abundant close antenna respectively, because shield is for providing isolation standard between the antenna.
As mentioned above, the shape of shield can change the shape of antenna coverage areas.Shield can have any material that can reduce near-field interference between the antenna and/or coupling to constitute.In addition, the thickness of shield, height and shape can change so that further reduce near-field interference and/or coupling between the antenna.Shield can have any material composition, and for example shield can be solid, hollow or have the solid basically of hole.Radio and/or system electronics can be placed on and/or be fixed in shield hollow and/or in the hole.Shield can be by being suitable for any material of this application or being combined to form of material.
Can also negatively influence the performance of antenna by making the antenna off resonance.Usually, antenna has a centre frequency and the scope round this centre frequency, moves effectively at this scope internal antenna.When its centre frequency and round the scope of this centre frequency during to higher or lower frequency shift (FS) and/or centre frequency remain unchanged and when descending the antenna off resonance that becomes around the bandwidth of this centre frequency.When antenna is placed very near can make the material of this antenna off resonance the time, the antenna off resonance that may become.For example, an omnidirectional antenna is placed near the metal material, can makes this antenna off resonance.A mobile phone antenna is placed near the human body, can makes the antenna off resonance.Can by for example design need antenna near shield become tuning, with not making the material shield of this antenna off resonance and/or utilizing the antenna dividing plate to separate antenna and shield, reduce the off resonance influence of shield to antenna.In one embodiment, the antenna operating characteristic can be selected to: when antenna used near shield very much, antenna was operated in the centre frequency of expectation, has expected bandwidth; But, when antenna when using away from shield, the antenna off resonance that becomes.In one exemplary embodiment, with reference to figure 8, antenna 14,16 and 18 utilizes antenna dividing plate 62 and shield to separate.The size of antenna dividing plate 62 and the amount that separates can be chosen to the amount of off resonance is reduced to the degree of expectation.
As mentioned above, shield can also change the shape of the overlay area of antenna.Shield can become to be suitable for any form of this environment or application with the alteration of form of the overlay area of antenna.For example, in one exemplary embodiment, with reference to figure 1-3, Anneta module 10 comprises 14,16 and 18 and one on three antennas shield 12 of triangle body basically.Each antenna is set at a summit of shield 12. Antenna 14,16 and 18 can be directly connected to shield 12 and/or antenna dividing plate.When antenna 14,16 and 18 was omnidirectional antenna, shield 12 was reduced to each overlay area 20,22 and 24 of antenna 14,16 and 18 less than spherical in fact zone respectively.With reference to figure 3, overlay area 20,22 and 24 can be expressed as the shape of final overlay area two-dimensionally.The overlay area can be overlapping to form virtual sectors 26,28 and 30.

In another embodiment, with reference to figure 8-10, Anneta module 38 comprises antenna 14,16 and 18 and shield 40.The shape of shield 40 is essentially the parabola on the negative camber.Antenna 14,16 and 18 is set on the parabola of shield 40. Antenna 14,16 and 18 can be installed on the shield 40 by antenna dividing plate 62, and/or directly is installed on the shield 40.When antenna 14,16 and 18 was omnidirectional antenna, shield 40 was reduced to each overlay area 20,22 and 24 of antenna 14,16 and 18 less than spherical basically zone respectively.With reference to Figure 10, overlay area 20,22 and 24 can be expressed as the shape of final overlay area two-dimensionally.Whether the shape of the parabolical negative camber of shield 40 and the skew of antenna dividing plate can determine overlay area 20,22 and 24 overlapping to form virtual sectors.In one embodiment, the parabolic surface of shield 40 is enough steep, to reduce overlapping between the overlay area significantly.In another embodiment, the parabolic surface of shield 40 is enough mild so that overlay area 20,22 and 24 is overlapping, and forms virtual sectors.The shape of overlay area can also change by the size of adjusting the antenna dividing plate.
