As described above, chokes boundary may be mounted on shield, therefore shield is for being attached at reflector for chokes boundary Upper (passing through shield) is highly useful, realizes the setting of chokes boundary in the suitable position of reflector (and relative in antenna Mandrel line) on.Fig. 2 B, 2C and 2D are the schematic diagrames of chokes region 10 (including crestal line).Chokes region, which is at least partly attached at, grips It flows on wall.In this embodiment, the chokes crestal line and chokes wall on the chokes boundary shown in Fig. 2A -3C, forms shroud encircling Multiple coaxial wire loops of central axis and side wall.For example, Fig. 2 B is chokes boundary from the outwardly extending schematic diagram of shield 8.Chokes Wall is laterally extended from shield side wall 8, and chokes boundary includes chokes wall and the chokes crestal line with the coincidence of shield side wall 8.Chokes wall Can be extended with any direction Yanzhong heart (longitudinal direction) axis of shield vis 8 (for example, inclined or parallel), but in some realities It applies in example, chokes wall approximately transversely extends relative to center (longitudinal direction) axis of shield side wall 8.Chokes shield can pass through one Or multiple connector attachments (or for being attached) are in the endpoint of reflector.Connector can be adhesive, banding material, spiral shell Bolt, glue, bolt, hinge, nut etc..Connector can be metal or nonmetallic, polymer, synthetic etc..Chokes shield It can be matched with the outside or inside of reflector.The outside or inside in reflector can be set in the chokes region of chokes shield, Can also be fixed in position by one or more above-mentioned connectors or tight fit (for example, interference fit) etc.,
Isolated choke boundary area may relate to the structure for being mounted on shield region or part, or be formed with shield side wall whole Body is overflowed for decaying or weakening the electromagnetism from antenna (for example, transmitting antenna, receiving antenna, transmit/receive antenna), from And reduce the unrelated signal for being sent to antenna.When isolated choke boundary installation (for example, passing through shield) is on reflector, antenna is sent out When sending or receiving ELECTROMAGNETIC RADIATION SIGNATURE, isolated choke boundary can decay or weaken the electromagnetic radiation being sent to or from antenna.Cause This in some embodiments, the choke for antenna system may include shield, which includes curved side wall, side wall Central axis is surrounded, side wall connects the first end and second end of shield side by side, which can allow electromagnetic radiation It passes through, the first end of shield is mountable in the forward opening of antenna reflector, and for assembling electromagnetic radiation to antenna, forward direction is opened Mouth end is for receiving electromagnetic radiation, and after installation, shield is set as distally extending from the forward opening end of reflector；Chokes boundary It is mounted on shield and is located at sidewall outer, when shield is mounted on reflector and antenna sends or receives electromagenetic wave radiation, The chokes boundary is sent to or the electromagenetic wave radiation from antenna for decaying.
Isolated choke boundary area is also possible to isolated gate described herein, isolation boundary, chokes, chokes boundary, isolation Chokes, chokes grid etc..Chokes boundary (for example, isolation chokes region) can have structure (including the ripple knot of multiple barriers Structure), such as crestal line, the cross-talk sent and received between parabola antenna disk can be weakened.These crestal lines have appropriate Height/depth and spacing can isolate the specific frequency range (for example, bandwidth) that the equipment uses.For example, grid structure is formed The depth or depth bounds of isolated choke boundary concentrate on used in bandwidth wavelength 1/4, this is retouched more detail below It states.Functionally, when antenna, which is located at adjacent paraboloid, to be sent between disk and paraboloid reception disk, chokes side is isolated Boundary can provide the isolation (for example, 10dB is isolated) greater than lowest level.
Isolated choke boundary (also referred to as chokes, chokes boundary or isolation chokes) may generally serve as two (or more) antenna Between barrier or baffle.For example, isolated choke boundary can be used as the barrier between transmitting antenna and receiving antenna.Chokes side Boundary can be used for inhibiting the propagation of wireless wave, and the frequency of the wireless wave is greater than or equal to 9GHz, and is less than or equal to 41GHz.This Multiple deformations of the wireless device of application can be used for bandwidth of the working frequency near 5GHz, so that chokes boundary may include It is a plurality of (for example, being greater than 3, to be greater than 5, be greater than 6, be greater than 7, be greater than 8, be greater than 9, be greater than 10, be greater than 11, be greater than 12, be greater than 13, greatly In 14, it is greater than 15, is greater than 16, be greater than 20, is greater than 25 etc.) the separated crestal line of spacing.These crestal lines can be parallel to the outer of shield Portion's frame.These crestal lines can also be parallel to one or more paraboloids for having chokes.Usually, chokes are isolated Along the plane perpendicular to shield endpoint (opening), (and perpendicular to parabola antenna, suitable position fills the crestal line that boundary includes Have shield) height extend.These crestal lines at least partly (can also whole) are along shroud encircling or second end or shield distal end Periphery extends.These crestal lines at least partly (can also be whole) prolong along the frame of shroud encircling or shield second end or shield distal end It stretches, in this way plane of these crestal lines perpendicular to shield distal end.The number of spacing, crestal line between the height of these crestal lines, adjacent crestal line The length of amount, the shape of crestal line and crestal line can be excellent based on used specific electromagnetism bandwidth (for example, wireless bandwidth) Change.For example, chokes boundary can with Optimization Work frequency 5GHz or so bandwidth, in this way, the device is in transmitting antenna and reception Signal isolation between antenna is greater than 70dB.Shown in choke elements can by improve 10dB isolation (for example, about 12dB every From etc.).
In some embodiments, isolated choke boundary area is formed by multiple layer metal (strip, sheet etc.) or other are approximate Material, setting (being combined together) adjacent each other, replaces some layers in the layer that these are combined, and is thus formed more A crestal line and channel.For example, in a way, chokes limiting bed can be combined by layering item, rib or other similar structure Formed together, then by the structural bending of the combination at desired curved surface (for example, in order to be mounted on parabola antenna and/or On the edge of shield).The material of these multilayers can be fixed together in any suitable manner, including splicing is (for example, pass through Resin or epoxy) and/or fixed by screw, be anchored, fasten, riveting or other similar mode.
When in use, when the second (for example, paraboloid) antenna is close to the first parabola antenna, and the first parabola antenna It is connected with chokes shield, when the second antenna is adjacent or close to first antenna and chokes shield, first antenna can be more effectively It is isolated with the second antenna.Usually, isolated choke boundary area can be set anti-in first antenna reflector and the second paraboloid Between the opening of emitter.Although described herein is the concrete condition using paraboloid, non-paraboloid can also With (substitution) use.
It may include: the first reflector for example, being used for the wireless transmitting system of wireless signal；For from the first reflector Send the radio-circuit of radiofrequency signal；The shield connected with the first reflector；And the isolated choke boundary connected with shield.Nothing Linear system system can also include the second reflector and isolated choke boundary, and the isolated choke boundary is for improving two paraboloids Overall signal isolation between reflector (between two parabola antennas).For example, the first paraboloid and the second parabolic The overall isolation of radiofrequency signal between the reflector of face, including the isolation provided by isolated choke boundary, overall signal isolation It can be greater than 10dB, 20dB, 30dB, 40dB, 50dB, 60dB (for example, greater than about 65dB, greater than about 70dB, greater than about 75dB, Greater than about 80dB etc.).For example, radiofrequency signal between the first paraboloid and the second paraboloid it is whole every From can be more than 70dB including the isolation provided by isolated choke boundary.
As described above, isolated choke boundary can also include crestal line.These crestal lines can be along the length of isolated choke boundary Direction (for example, direction of the external frame of reflector) extends.The height of these crestal lines can be the same or different.One In a little deformations, the height of these crestal lines can change.For example, crestal line adjacent in isolated choke boundary can be by channel point It opens；In some deformations, the depth of each channel can be greater than the width (distance) of adjacent crestal line.Depth between channel can With consistent or different；In some deformations, the depth in a channel is also that can change.
For example, isolated choke boundary can be set to prolong along the curved boundaries of two adjacent shields or paraboloid It stretches, and may include a plurality of crestal line adjacent to each other；The perimeter that these crestal lines can be open according to two of paraboloid Arrangement.Also chokes boundary can be set, so that a large amount of crestal line is arranged along sine curve, that is, the top of adjacent crestal line or The diameter that sine curve passes through isolated choke boundary is formed on bottom.Therefore, in some deformations, the ridge of these isolated choke boundary Line is arranged along sine curve.All isolated choke boundary described herein can have different section wheels on its horizontal section It is wide.Alternatively, in some deformations, isolated choke boundary has a high profile of asymmetric rib, thus it is symmetrical it is not necessary to.
Therefore, as described above, different height can be had by being at least partially isolated the crestal line on chokes boundary；Chokes side is isolated The adjacent crestal line in boundary can have different height and be separated by the channel of different depth.These are in isolated choke boundary neighbour The channel between crestal line connect can be separated from each other with the score of some wavelength lengths.These ridges adjacent in isolated choke boundary The depth of channel between line can be the 1/4 of the centre frequency of used device.Exist for example, device is suitable for sending frequency Signal between 5.4GHz and 6.2GHz, the depth of the channel in isolated choke boundary can about 13.9mm and 12.1mm it Between；It is the device between 4GHz or so and 8GHz or so for being suitable for frequency, the depth of the channel in chokes boundary can be Between about 18.8mm and 9.4mm.
In above-mentioned all embodiments, top view as shown in Figure 3A, choke may include only partially surrounding shield The chokes boundary part that cover side wall extends.Fig. 3 A shows another chokes part 34, can be used as one of chokes shield Divide and is mounted on antenna reflector.Still in this embodiment as other embodiments, chokes part 34 is chokes frontier district 34.Chokes frontier district can have any shape or direction, including shape described here or direction (for example, relative to other The position on chokes boundary).For example, chokes frontier district may include crestal line and channel.The height and depth of these crestal lines and channel It can be same or different.The a part of of chokes boundary can be overlapped with a part (beside portions) of shield, in this way, chokes side The another part on boundary may be located remotely from shield (as shown in Figure 2 B).
Fig. 4 A-4C is the chokes shield schematic diagram for including antenna house.In this embodiment, chokes guard apparatus can be installed On antenna reflector, and the chokes boundary including being surrounded or partially surrounded shield.Fig. 4 A is that have cylindrical shroud region (side Wall 8) chokes shield 4 schematic diagram, chokes shield can be attached at the proximal end of reflector.Fig. 4 B is shown in chokes shield Mandrel line 15.The chokes shield includes antenna house 60.In figs. 4 a-4 c, antenna house covers the outside of entire distal surface, packet Include the distal openings across chokes shield and chokes frontier district 55.Chokes frontier district 55 is mounted on shield region (for example, shield Cover side wall 8) on and around the shield region.Although shown in figure is right cylindrical, shield region may not be positive cylinder Shape.As described above, isolated choke boundary only can partially extend around the opening of shield or paraboloid.For example, Isolated choke boundary can partially extend around chokes shield (or chokes shield of reflector).
Isolated choke boundary area can extend along the edge (for example, shroud encircling or shroud encircling endpoint) of shield, or Reflector opening is extended around, so that the angle of shroud encircling, protective cover end or reflector opening is less than 180 degree, extremely at about 30 degree Between 180 degree (for example, being at least about 40 degree, 50 degree is at least about, is at least about 51 degree, 52 degree is at least about, is at least about 53 Degree, is at least about 54 degree, is at least about 55 degree etc.).In all these deformations, isolated choke boundary, which can dangle, is being protected On the outer edge of cover portion or parabolic reflector wall.For example, chokes boundary can dangle anti-due to shield relative narrower In emitter and shield.
Fig. 5 A-5C is the schematic diagram of chokes frontier district.In this embodiment, optical absorbing material (not shown) can To be arranged in shield side wall close to chokes boundary, but it can also replace setting and it is arranged in elsewhere or additionally He is local.For example, optical absorbing material can be set on the side or distal end of chokes frontier district, covering part or whole Shield region.Optical absorbing material can be on shield or in shield, or on the chokes boundary of part, such as chokes On wall.Optical absorbing material can be used for weakening from or be sent to antenna deviation or unrelated radiation, on the antenna It is attached with chokes shield.
As shown in figures 5a-5c, there be a large amount of (for example, more than 3, more than 4, more than 5, more than 6, be more than in chokes frontier district 7, be more than 8, be more than 10, etc.) crestal line；The maximum quantity of crestal line is determined by the space of receiving crestal line (for example, chokes shield Diameter can have much).Usually, chokes shield need to have about 3 to 40 crestal lines, that is, 5-40 crestal line, 10-40 crestal line, 10-30 crestal line, etc..Fig. 5 D is the side view of chokes frontier district, which can install (or being integrally formed) and exist On chokes region.As shown in Figure 5 D, the height of these crestal lines is about consistent with width, and concentrically arrangement adjacent to each other.Figure 5E is the cross-sectional view shown in the direction Fig. 5 D.
Fig. 6 is the chokes boundary schematic diagram of another embodiment, which may be mounted on shield.In the embodiment In, chokes frontier district is formed by the crestal line of a large amount of (for example, 7), these crestal lines distally (central axis relative to chokes shield Line) extend different distances.Therefore, the possible size difference of these crestal lines or adjoining dimensions, but it is arranged in song as shown in Figure 6 On (for example, sinusoidal) face.
In use, chokes shield can be used for decaying from/be sent to paraboloid off-axis line (for example, other Penetrate) radiofrequency signal.For example, Fig. 7 is the side view for being attached with the antenna of chokes shield.Chokes frontier district is cut off in the figure , it is divided into the first chokes boundary part 90a and the second chokes boundary part 90b.Antenna house 89 may be mounted at the distal end of shield In opening.Antenna house is highly useful for protection antenna system.Antenna house can make electromagnetic radiation (for example, wireless wave) wear It crosses, but other substances is arranged and are hindered.For example, mechanical barrier can be set to prevent other substances, such as air in antenna house (wind), animal, fragment, dust etc. enter antenna system (for example, into chokes shield and/or reflector or by reflector Determining inner space).Antenna house can protect antenna system from damage.Antenna house can be installed with fixed relationship (or to be set It is set to for installing) in shield.Antenna house can be installed or be provided for be mounted on any position of shield.For example, Antenna house may be mounted at the first end (proximal end) (for example, being provided for being mounted on the protective cover end of transmitter) of chokes shield, But more common situation is that may be mounted at the second end (distal end) of shield (for example, and being not configured to install with reflector 74 Protective cover end).As described above, shield can install (or being provided for installing) on reflector in a position-stable manner, thus day Irdome can install (for example, passing through shield) on reflector in a position-stable manner.Antenna house can be with covering part or whole antennas The opening of reflector or shield.O-ring can be used to ensure that safety of the antenna house on rear side of the edge of shield or reflector.It is O-shaped The extension of ring can close the rear side and antenna house of isolation chokes.In some deformations of chokes shield, shield first end is Opening, and second end includes the antenna house being mounted on chokes shield, and when chokes shield and antenna house are mounted on reflection When on device, for preventing substance into the inner space determined by reflector.Antenna house can be substantially over chokes shield Entire second end.Antenna element (for example, feed 77) in reflector can also be choked shield covering.In some deformations, Chokes shield extends along the opening towards distal end of reflector, overlays on feed so that antenna house can be put down.
As described above, usually, the scale in chokes region, such as the quantity of crestal line (and channel), height, width, Away from etc. can be optimized according to the decaying of the specific frequency (range) of antenna system.For example, the depth between crestal line may be about 1/4 of wavelength used in system.It is adjacent in the case where antenna system is used to send and receive the signal that frequency is 4GHz to 8GHz Crestal line between depth can be in 18.8mm to (for example, center be 13mm near) between 9.4mm；In antenna system for sending out In the case where sending and receiving the signal that frequency is 5.4GHz to 6.2GHz, depth between adjacent crestal line can 13.9mm extremely Between 12.1mm.By the arrangement of these crestal lines, edge diffraction can be made to minimize and weaken adjacent transmitting and receive day Communication energy between line disk.Isolated choke boundary area, which is arranged, can make the frequency range of isolation adjustable, hereafter will to this It specifically describes.For example, isolated choke boundary area can be adjusted and adjusting the height of its crestal line.
Isolation boundary region may be mounted at the outer edge on (or being at least partly more than) chokes boundary.In some deformations, Chokes frontier district can be suspended in the distal openings of shield region.For example, chokes shield region may include more than 12 vallates Line.These crestal lines can have the inclination less than 0.35 inch.These crestal lines can be arranged with the curvature of the opening of reflector. These crestal lines can be separated by channel.The segmentation (for example, width and/or depth of channel) of crestal line can be it is constant can also To be variation.In some deformations, the height of crestal line is different.For example, adjacent crestal line can have different height (from high to low or high/low alternating, etc.), extends the plane of the opening of reflector to "upper".
Those above embodiment describes the different arrangements of these crestal lines and channel.Usually, chokes frontier district can To be set as low Q structure, so as to which crestal lines more as far as possible is arranged, without being limited by the ability of the antenna connected.
As shown in figure 6 above, the arrangement of the crestal line of chokes frontier district can make these crestal lines in one plane, not abut Crestal line can be by curved surface (for example, sinusoidal) or cascade arrangement.For example, perspective view shown in fig. 6, from along surface to The upper surface for the chokes frontier district that the crestal line that side extends is formed is uneven.The apparent height of adjacent crestal line also not phase Together, main surface ("top" on chokes boundary) of some crestal lines along chokes boundary extends outwardly more.In side view shown in Fig. 7 It becomes apparent.The crestal line of the part across chokes center in figure, it is shown that these crestal lines are arranged with curved surface (for example, sinusoidal) formula The case where.The apparent height of these crestal lines is different from.In some deformations, gap and/or depth between crestal line can also be with Not identical (for example, in 9mm between 19mm).
As described above, chokes frontier district and the surface of shield region can be bent with antenna house.As shown in fig. 7, some In the deformation of chokes shield, chokes region be can be set on the edge of shield region, and in the son reflection of each reflecting system (prolong than sub- reflector and project farther) before device.In this embodiment, chokes frontier district has in high frequency salient point (carinate point) Low frequency wave attribute.When antenna reflector (antenna) and other adjacent or close antennas, antenna reflector (day is can be improved in this Line) isolation.
In some deformations, isolated choke boundary area and/or chokes region may include absorbing (for example, microwave absorption) material Expect a part as its structure.The energy relative to use device within the scope of certain frequency can be absorbed in the absorbing material. For example, when chokes boundary is arranged between two antenna disks, absorption band or uptake zone, such as microwave absorption band or microwave Uptake zone can extend between two antenna disks.A kind of microwave material includes being filled with the polymeric material of magnetic particle；This is slightly Grain can have high magnetic susceptibility (magnetic loss characteristic) and high permittivity (dielectric loss characteristics) simultaneously.Absorbing material can be solid Body (for example, magnetic) absorbs and/or foam absorbing.For example, foam absorbing, is also possible to Open cell shape, or to pass through Material (for example, carbon coating) dipping lossy to certain frequencies is made.Absorbing material can be in chokes shield (for example, edge Chokes shield long axis extend, be arranged among two reflection disks).Absorbing material can have any suitable thickness, Width and length, such as in about 0.5mm to the thickness and/or width, etc. between 5cm.Absorbing material can have shape (example Such as, may include salient point, crestal line etc.) and/or form the crestal lines of one or more chokes frontier districts.
Application also describes isolation boundary (isolated choke boundary) region, can with the adjusting of automatic or manual with adapt to every Off-frequency rate.For example, isolation chokes shield can by adjusting the crestal line extended between reflector height to adjust.According to expectation Transmission/reception frequency bandwidth, adjustable crestal line height is specific height or altitude range/distribution.Usually, according to Bandwidth, the height of crestal line can be the score of wavelength (for example, 1/4), and can be set to or be with the centre frequency of bandwidth Center.For example, the working frequency of bandwidth is 5470-5950MHz, centre frequency 5710MHz, then the crestal line in chokes region Highly (or centre-height) is about 13.25mm.Similar, the working frequency using bandwidth is 5725-6200MHz, centre frequency For 5962.5MHz, then the height (or centre-height) of the crestal line in chokes region is about 12.6mm.Therefore, if using adjustable The chokes region of section, then the height of these crestal lines can be adjusted to from about 13.25mm if the desired bandwidth to work changes 12.6mm。
The height of these crestal lines can be adjusted by mechanical adjustment crestal line, so that their extended or retracted chokes boundaries Pedestal.In some deformations, these crestal lines can mechanical (and/or electric power) extended or retracted pedestal to be adjusted to different height Degree.These can highly be manually adjusted, that is, use handle or other manipulation devices, the manipulation device including preset height, this is pre- If height corresponds to the desired bandwidth of work.All these devices can also automatically adjust, that is, control wireless circuit It can control and/or adjust the height of isolation barrier crestal line；If the bandwidth of operation of conversion equipment from bandwidth (for example, Another bandwidth (for example, 5725-6200MHz) 5470-5950MHz) is arrived, then it can be tuned automatically, or adjusts chokes area The height of the crestal line in domain.For example, the height of crestal line can be adjusted between about 4mm and about 20mm (for example, 8mm to 20mm, 10mm to 18mm, etc.).In some deformations, the spacing between crestal line is adjustable.
Usually, a large amount of crestal line in isolated choke boundary area can extend across shield area and/or paraboloid is anti- The external margin of emitter.Chokes boundary (" chokes ") may include any an appropriate number of crestal line.For example, chokes region can wrap Include at least 10 crestal lines or the crestal line of any other above-mentioned quantity.As described above, chokes frontier district may include a plurality of crestal line.? In some deformations, be isolated chokes region crestal line the first subset, can be bent with the external margin of the first protective cover end (every In principal plane from chokes boundary), the second subset of the crestal line in chokes region is isolated, it can be with the external edge of the second protective cover end Edge bending.
All isolated choke boundary areas described herein can have different cut open from the point of view of the cross section in chokes region Facial contour, but be typically all symmetrical relative to long axis plane.Optionally, in some deformations, chokes region has not The symmetrical high profile of rib, thus it is symmetrical it is not necessary to.
