Abstract

A portable wireless communications device such as a telephone handset having a vertically corrected antenna module pivotally secured to the handset for rotation about a first pivot axis. The antenna module can be rotated into a predetermined orientation, independent of handset orientation. An antenna mounted on the module is oriented vertically when the module is in the predetermined orientation. When the antenna module is rotated for use, a mechanism incorporated in the module support structure automatically rotates the antenna module about a second pivot axis which is substantially perpendicular to the first. This second rotation places the antenna at an angle that compensates for tilting of the handset during use about an axis parallel to the second axis, or along the first. That is, the antenna is shifted by a preselected angle in vertical orientation, typically around 10-15 degrees, in a direction perpendicular to the first direction of rotation to compensate for positioning a

Description

The multi-axis vertically corrected antenna of handheld wireless communications devices

The background of invention I. FIELD OF THE INVENTION

The present invention relates generally to satellite communication, more specifically relates to a kind of portability or cell-phone of using do wireless telecommunications by communications satellite.This invention further relate to a kind of revise antenna with respect to the upright position of multiaxis line more effectively to transmit the method and apparatus that signal is used.II. the description of relevant prior art

In the wireless or honeycomb mobile telephone system, all communication signals are to use all fixing base stations to receive between all system users and transmit at continental rise, and this base station is also referred to as the unit platform, and each such unit platform has covered a specific geographic area.In Satellite Communication System, between the gateway of all system users and all use satellites, transmit same signal.Satellite is often used in the large-scale communication system providing service in sizable geographic area, and this large-scale communication system is provided at the user fixing or that move of extensive distribution or the communication between the user's set.Such system is 4 as being described in the patent No., 901,307, announcing United States Patent (USP) and the application number that day, are called " the scattered band multichannel communication system that uses satellite or land transponder " February 13 nineteen ninety is 08/368,570, name is called in the U.S. Patent application of " using the method and apparatus of gamut transmitting power at a scattered band communication system that is used for following the tracks of single receiver phase time and energy ", these two inventions have all transferred assignee of the present invention, and are cited in this paper.

In such system, use the user's set of telephone-type mobile phone to have all wireless sets that are used for receiving, handling and pass through exterior antenna transmission communication signal usually.These radio transmitters are connected in microphone, loud speaker, visible display device and antenna suitably in the mode of the prior art known.Antenna is according to operating frequency and antenna pattern specialization, and the orientation of antenna is crucial for correctly transmitting signal with satellite.

Be used in all antennas on the user's set in the Satellite Communication System and have separately antenna pattern, basically from self place horizontal plane or horizon upwards effectively energy is coupled to satellite or from the satellite received energy.It is vertical that the orientation that is kept as a mobile phone is not in antenna, or in use be transferred to a non-perpendicular orientation, and then antenna pattern (local ground level) also is located in this ground level is had angle.In this position, some satellite positions are lost or the heavy damage communication owing to this antenna pattern no longer covers, or owing to a low-yield part is made the transmission that has reduced energy in alignment with other parts.Along with the difference of the angle of phone, even also can lose in the communication of quite high height above sea level place and satellite.

In order to remedy this influence, can its antenna pattern can be extended to below the horizon at its place Antenna Design.That is to say that regulate antenna pattern to such an extent that this antenna is reached below the horizon, like this, the non-perpendicular location of some of this phone still can be positioned at required antenna pattern with all satellites.Unfortunately, even perpendicular alignmnet and reach best location with respect to all satellite positions, this Antenna Design can not transmit signal energy effectively.Meanwhile, after this phone fully rotated, the result still will destroy its work, unless its antenna pattern extends to such an extent that be significantly less than the horizon.

Can revise some mechanisms that the vertical orientation of an antenna is used in using automatically by being provided at phone, propose these problem in all patent applications that disclose and quote in the above.These mechanisms use gravity to force an antenna supporting component to rotate and an antenna are remained on a vertical orientation.But although these technology have compensating action to phone around the rotation of an axis, actual phone uses the rotation that includes around two above axis.That is to say that many telephone bandsets have quite flat front and do not accord with the shape of user's facial features or operating habit.Although this is to be convenient to make, deposit and transport, make a telephone bandset such situation occur, be make a loud speaker in alignment with a user ear and make a microphone place user's mouth near, need this mobile phone is departed from vertical line one angle.Usually, this deviation angle is big is 10 ° from vertical line extremely.Departing from like this means: as mentioned above, still have influence on the transmission of signal.

So, need a kind of new antenna direction controlling organization, this kind mechanism can compensate in use that mobile phone moves or depart from around the angle of two above axis, keeping a vertical orientation, but can not bring undue complexity or from telephone subscriber's interference.

Brief summary of the invention

A purpose of the present invention provides a kind of the portable of a vertically corrected antenna or handheld wireless phone mobile phone of having.

Another object of the present invention provides a kind of vertical orientation adjusting device with respect to two axial lines.

An advantage of the present invention is, makes this antenna more effectively energy is coupled in the satellite communication circuit, makes user's interference effect minimum.

Reflect these and other purposes, advantage and purpose in the wireless telecommunications system as a portable phone, this portable phone has with a microphonic mobile phone and the loud speaker installed along a wall of a mobile phone shell.One antenna module is to be fixed in the part of this shell around a pivotally supported mode, so that around one first pivoted.Such rotation allows this antenna module in use to be placed in a predetermined orientation around first axle, and irrelevant with the orientation of mobile phone.When antenna module was in predetermined orientation, an antenna that is installed on this antenna module extended along a vertical direction from this assembly.This mobile phone is pressed its version moving or automatic vertically corrected antenna position of armrest when needed.Other provides a kind of device or mechanism, is used for also locating or rotate this antenna module around one perpendicular to second pivot of first pivot, promptly provides vertical orientation around second axis to reach along first axle.

In one embodiment, being used for respect to the second pivotally supported device is by realizing on the supporting walls that this antenna module is installed in the expansion of one on the mobile phone.This supporting walls can form the inwall in an indent district.Usually a kind of with in several known pivots realizes this installation as bearing or rotating dog, and this mechanism is installed on the center on the mobile phone wall.It is one substantially parallel and be connected in the inwall of the expansion of shell wall that antenna module has, and have one to place the passage that this pivot is used.

Mobile phone and antenna module inwall are parallel to each other, but are positioned at a public preselected angle with respect to an axis that limits in advance of mobile phone.Operating or during the curling position, the position of this antenna makes the one central axis with respect to the internal antenna component walls one preselected angle be arranged one.Antenna angle usually and this two wall with respect to the deflecting angle of handpiece axis.So although antenna can depart from some angles from the handpiece axis that preliminary election limits, this antenna is generally shelved when its curling position and is parallel to the handpiece axis that limits in advance.The one typical handpiece axis that limits in advance extends between the microphone and a loud speaker that is used respectively separately during the mobile phone operation, and represents an axis, and this axis tilts during mobile phone operation with align loud speaker and microphone for use.Meanwhile, first pivot is same as or is parallel to an axis, and in use mobile phone is around this rotational.

When this antenna module during around first pivoted, the part addition each other of the deflecting angle of two walls makes the two sides of antenna module produce a deflecting angle with respect to the handpiece axis that limits in advance.When antenna module rotated about 180 ° from a curling position, the angle between the handpiece axis of the central axis of antenna and qualification in advance was the deflecting angle sum of antenna axis and two walls.

In a most preferred embodiment, the deflecting angle between mobile phone and the antenna module wall is in 5 ° of-8 ° of scopes, center of antenna axis runout or be set in angle from the such size of antenna module inwall.Make that so the total deflecting angle scope when antenna module rotates 180 ° from the curling position is 10 °-16 °, and the total deflecting angle scope when antenna module rotates 90 ° is 5 °-8 °.So when antenna module rotates the back with Antenna Positioning and when using, antenna just departs from automatically by this angle in advance or does vertically correction.The inclination of the axis that this angle payment of selecting according to each device purposes limits in advance.

In another embodiment, being used for respect to the second pivotally supported device is to realize that by this antenna module being installed on the supporting bracket of launching this supporting bracket is installed on the mobile phone with a Pivot joint again.This antenna module as described in the past, is to be installed on this supporting bracket with a kind of of several known pivot on the center that is arranged on this plate.It is one substantially parallel and be adjacent to the inwall of the expansion of this plate that this antenna module has, and have one to place the passage that this pivot is used.

This plate and antenna module inwall are parallel to each other basically, still, this plate can be set in the place of the angle of one or more preliminary election with respect to an axis that limits in advance of this mobile phone.This is by using one this plate is installed in this plate on this mobile phone at the Pivot joint that rotates between two extreme positions realize.A position normally makes the upper surface of plate be parallel to the axis that limits in advance, and the another location is to make that surface press from both sides a required angle with respect to this axis that limits in advance.This antenna normally is parallel to the central axis location of antenna module inwall with one.

So, although antenna can depart from some number of degrees of handpiece axis that limit in advance, when drawing (initial) position in, total antenna is to be parallel to this axis to be placed.The one typical handpiece axis that limits in advance extends between the microphone and a loud speaker that uses during the mobile phone operation, and represents an axis, and this axis tilts during mobile phone operation with align loud speaker and microphone for use.Meanwhile, first pivotal line is same as or is parallel to an axis, and in use this mobile phone is around this rotational.

In the further situation of this embodiment, this supporting bracket is to use the pivotal arm on the relative both sides of two peripheries that are positioned at this plate to be installed in a recess on this mobile phone.Each pivotal arm is surrounded and supports this torsion spring by a torsion spring, this torsion spring is matched with this plate and is matched with a wall of this recess at its other end at the one end.All springs apply a revolving force with respect to an axis that is limited by all pivotal arms to this plate.Perhaps, can coil spring or sheet spring be installed between this plate and this mobile phone, so that a lateral deviation of this plate places this mobile phone.When antenna does not use, have a bolt lock mechanism that this plate is fixed together and begin or non-deviation position, and plate is released and moved by spring force in the time will using antenna.

Each mobile phone preferably includes a total rectangular shell, and this shell has an antetheca and back, the upper and lower and isolated sidewall that microphone and loud speaker be housed thereon.Antetheca also can have a keyboard and a visual display unit.Antenna module preferably is pivoted on the rear wall of shell, one recess can be set with the assembly that fixes up an aerial wire rear wall with upper end shell adjoiner.The shaped design of antenna module preferably accomplishes, is adjacent to or when being positioned at position not operation, that store of total outline of mobile phone when antenna changes one over to, in this recess of packing into and make all outer surfaces flush all neighbouring surfaces in this shell basically.Also a recess can be set, be used for when storage location, placing this antenna.In further situation of the present invention, can use a relieving mechanism in this recess, to discharge this antenna from storage location.

Wireless device can only be specified be used for satellite communication, perhaps also can be used for as aspect other radio purposes of traditional cellular communication system, and additional, a built-in honeycomb fashion communication antenna can be arranged.

The pivot device of antenna guarantees that antenna can be vertically oriented and irrelevant with the orientation of the mobile phone of reality, has reduced the risk that causes the loss of signal owing to incorrect antenna direction.The cellie needn't be an antenna direction with respect to second pivot, but antenna module changes a correct vertical orientation along first axle and around second axis under the influence of biasing installation surface or spring-loaded support platform.So, antenna remains on a vertical orientation of optimizing so that satisfied reception and the emission of antenna.Meanwhile,, the antenna pattern of antenna is optimized to have a more vertical antenna pattern, makes the transmission of signal energy or coupling more effective, thereby improved communication owing to make the antenna of installation can guarantee to have a suitable vertical orientation according to the present invention.

The description of most preferred embodiment

The present invention be a kind of when using a portable radio communication equipment antenna vertical orientation on it to improve the technology that signal energy is transmitted by all satellite repeaters and gateway type base station.The present invention can also make improvements the antenna pattern of antenna, the further like this performance of improving antenna system.

By an antenna or antenna mechanism are fixed on the antenna module that rotates on the rear wall that is installed on communication apparatus, make the present invention obtain these functions.In this equipment used, this assembly can forward on the many positions that make the antenna vertical orientation around one first pivot.When this antenna module in use rotates, be arranged in the assembly supporting mechanism a mechanism automatically with this antenna module around second pivoted that is substantially perpendicular to first pivot.This second rotation places an angle with this antenna, this angle compensation in use this mobile phone around a rotation that is parallel to the axis of second pivotal line.That is to say that this antenna moves about 10 °-15 ° along a direction perpendicular to first rotation direction in its vertical orientation, with compensation to a loud speaker and microphonic location and for use.

Fig. 1 and Fig. 2 at first express a kind of telecommunication equipment that has adopted by the portable or cell-phone form of principle formation of the present invention and operation.In Fig. 1 and Fig. 2, the portable phone or the telephone bandset 10 that illustrate have a housing, this housing have front and

back walls

12 and 14 and down, soil and

sidewall

16,18,20 and 22.Being installed in rotation on a antenna 24 on the rear wall 14 of this phone draws the NOR operation position in one and is collected in one along in the long recess of rear wall 14 and the intersection of sidewall 20.

This antenna 24 is to be used in the many kinds of antennas of various Satellite Communication Systems any, such as quadruple screw shape antenna or eight line helical aerials, but is not limited to these two kinds.The antenna that is used in these systems usually will be with two frequency work.Preferably in this phone 10, adopt a little or compact antenna structure design, preferably adopt cramped construction as eight line helical aerials.In two U.S. Patent applications that be respectively 08/513317 and 08/532921 at application number, title are respectively " the quadruple screw shape antenna and the network of feeding " and " biobelt eight line helical aerials " such antenna has been discussed also, this this paper has been added quoted.But those are familiar with those of ordinary skill in the art and also recognize, resemble the occasion that will use stacked antenna for some, can use a kind of telescopic antenna or radome.Illustrated antenna 24 has a telescopic upper body of inserting a lower house.

Telephone bandset 10 comprises that one is roughly shell rectangle, that make with known lighter material such as light plastics.The cover that is used to make antenna 24 usually with similarly gently plastics make.In general, as can be known, can on many surfaces of this mobile phone and wall, adopt with what shape and surface voids were represented one or morely to meet ergonomics and stylish design feature from prior art.

For example, the part of front wall surfaces outwards can be extended towards a use thing that a microphone 26 is installed, improving picking up of sound, and, can use a surperficial extension or recess to keep a loud speaker 28 on the top of the antetheca of this mobile phone.Fig. 1 has represented some such characteristics, is respectively applied for the input of information in addition and shows traditional keypad and a Zhu Jian 30 and a visual display 32.One loud speaker 28 is installed on antetheca, in use this loud speaker generally be positioned at the user ear positive or near.But when phone being put into surperficial going up after user's ear is removed, function of the present invention is similarly good.

Represented to have installed on rear surface 14 antenna 24 in the rearview shown in Fig. 2 and 3, further details table is shown in the Figure 4 and 5.In Fig. 2 and 3, antenna 24 is installed on the antenna module 34, and this antenna module is installed in rotation on a Pivot joint 38 on the recess 36 on the rear wall 14 of this telephone bandset.This Pivot joint 38 limits a pivot 40, and this pivot is approximately perpendicular to rear wall 14 or and extends through loud speaker and microphonic predetermined handpiece axis, will also will discuss in the back this.This shell has a long recess 44 that extends along a side of rear wall 14 or edge, placing antenna 24, or a cover that is used to hold all antenna elements is when not in use arranged.Other places a releasable snap-fastener or locking devicen so that this antenna is remained in the recess 44 releasedly.For example, a snap lock rationed marketing or lock bolt 45 are arranged in the lower end of recess 44.But, one ball-nest type locking mechanism or other mechanisms known in prior art also can be set.

The shape and size of recess 36 can be matched with the shape and size of antenna module 34 basically, and like this, as Fig. 1, during the inoperative position that draws in one shown in 2 and 8, assembly 34 flushes with all adjacently situated surfaces of mobile phone basically.In an illustrated embodiment, total rounded of recess 36 also has the lower wall 48 of a flat inwall 46 (Fig. 4) and a bending, but do not use sidewall or the upper wall that flushes with

wall

18,20 and 22.But when needed, these other wall can be used in combination with the wall 46 in the recessed more rear wall 14.In this embodiment, wall 48 is rounded, and its height that is adjacent to other positions of aspect ratio of

sidewall

20 and 22 hangs down.The upper wall 18 of this mobile phone has with the lower wall 48 of this recess similarly circular.

As mentioned above, antenna module 34 and recess 36 have the shape and size that match basically each other.Can select arbitrary shape, antenna module 34 is freely rotated around pivot 40.But, when selecting the shape of antenna module, preferably all neighbouring surfaces of its shape and shell are matched from aesthstic angle.In this example, antenna module 34 is roughly circular, and its upper and lower

circular side wall

50 and 52 the approximate curve shape with upper wall 18 or recessed wall 48 of curved shape match, and its

sidewall

54,56 then aligns with sidewall 20 and 22.In addition, described below all purposes aspect, the profile of antenna module 34 must approach as common Adjusting Shape with outer wall 58 as far as possible, and edge especially outwardly like this, extends seldom it above the molded lines of the rear surface 14 of mobile phone.Select and use the fine understanding of total energy for the designer of communication technique field of the criterion of given shape or technology during one phone in design.

All walls of antenna module are made by being similar to manufacturing mobile phone lighter material 12 usefulness, known usually.In this embodiment, as shown in Figure 2, many radiating fins parallel to each other 59 are arranged on the outer wall 58 of this assembly 14.These fins 59 are the suitable materials that have improved heat dissipation characteristics with a kind of, make as the material of aluminium and so on, and the plastic material that maybe can adopt some to be generally used for making the remainder of antenna module is made.Antenna 16 can use stickiness compound, limit screw, locating ring or thread surface, adopts as the prior art of interference fit (but being not limited to interference fit) to be fixed on the lower wall 52 of antenna module.

As clearly expression in Fig. 2 and 4, antenna supporting component 34 can be installed on the bottom of the planomural 46 on surface of recess 36 or recess 36 with a Pivot joint 38.This Pivot joint 38 comprises pivot member, pin or the parts of bearings of an almost fixed in the center of wall 46.Some structures like this are familiar in prior art, select to adopt which kind of structure according to making requirement, expense, load and some other factor of knowing.For illustrated this purposes, Pivot joint 38 shown in Figure 4 has adopted a kind of Bearing assembly 60 with an inside race 62, outer race 64 and bearing 66.

Antenna module 34 has a flat inwall 70, and this inwall and all

walls

50,52,54 link to each other with 56, or form the part of these walls.It is adjacent with wall 46 that inwall 70 is positioned at, and one centre bore 72 is engaged in the top of Pivot joint or parts of bearings 60 rotationally.Parts of bearings 60 is prior arts of utilizing as interference fit (but being not limited to interference fit), or a flange and screw component are installed on the flat inwall 46.Interior cylindrical supporting walls or seat ring 62 extend outwardly from inwall 46, and are fixed in antenna module 14 with a flange 68.To this, for example use all Screws to pass flange 68 and be screwed into wall 70 to be achieved.Perhaps, as being significantly, available other flanges and bolt structure, multiple adhesive, contain the potting compound of intermixture, or locating ring, clip and lock pin are fixed in antenna module on the seat ring 62 to being familiar with those of ordinary skill in the art.If required, also availablely use to do damping just like an outside damping piece that is affixed on the fiber mat (not shown) of two seat rings.

One internal channel of Bearing assembly 60 or hole 74 are provided with a path between the body of the inboard of antenna module 34 and mobile phone, at this many multiple traditional or known electronic components that are used to make a portable phone are arranged.Preferably, some electronic components that are used on the mobile phone are installed within the antenna module 34, rather than in mobile phone.In illustrated embodiment, the radio-frequency (RF) component 76 and 78 that consists of the part of all known circuits is installed in one and is positioned on the circuit board 80 of antenna module 34.Antenna 24 is connected in these elements by a coaxial line cable 82, and with a coaxial cable 84 that passes hole 74 all radio-frequency (RF) component is connected in other elements in mobile phone.

Between the wall 46 of antenna module 34 and recess 36, be provided with air ring, ring or packing ring 86 that certain material is made.This kind material comprises multiple known low surface friction or in the self-lubricating material any, and this kind material not only can make antenna module 34 but also the frictional force when rotating is less.Meanwhile, selected this material can help the buffering that moves to antenna module 34.In addition, between

wall

46 and 70, can adopt one to set up the antenna locator used of allocation really, also will discuss this below.

Adopted the mounting means of the above-mentioned type, antenna module 34 just can freely rotate with provide a kind of can be around the ability of a pivot 40 corrections or adjusting antenna vertical orientation.That is to say that in order to use, a mobile phone user can forward antenna to one required upright position, to improve communication.The rearview that Fig. 3 represents has been represented the many positions with respect to the antenna 24 of mobile phone 12.In general, antenna 24 needn't change more fartherly than the position shown in the right side of Fig. 3, and for this reason, an available stop mechanism (not shown) is to prevent further clockwise rotating of antenna.Available all lock pins to be discussed below or locator are set different positions.

When using, can provide this vertical correction automatically in conjunction with other elements such as counterweight or magnetic force actuator and driving mechanism.But, aspect many purposes, also wish to carry out the vertical correction of aerial position around one second axis.In the present invention, the mounting structure that is used for antenna module 34 provides such correction.

Antenna module 34 is installed to such an extent that make also can be around second rotational perpendicular to first axle 40, so that vertical antenna is aimed at respect to two axial lines in recess 36.This is to realize by the shape of revising the interface between antenna module 34 and the wall 46.When this antenna module forwarded a curling position to, all matching surfaces that use in this interfacial structure were parallel to each other but will be with respect to proficiency arbor lines that limits in advance, or with respect to all outer walls, the common angles of a preliminary election are arranged.In other all aerial positions, all skewed surfaces interact to produce departing from respect to second axis.Fig. 4-6 has represented this situation in detail.

Now see Fig. 4, wall 46 also is not parallel to antetheca 12, but tilt, like this, antetheca 12 is more approached than near the position the recess 48 near the position the roof 18.So just between

wall

46 and 12, form a bias angle theta.What Fig. 4 represented is at wall 12 and perpendicular to the angle between the axis 40 of wall 46.In Fig. 4, antetheca 12 is only as illustrating, wall 46 can be set to and be parallel to antetheca 12, but with respect to any other surface or predetermined axis runout one angle by mobile phone 10, especially when antetheca 12 itself has one to be the shape of angle or variation (as shown in Figure 1).The major function of this oblique angle or drift angle is when the rotation or the inclination of a loud speaker and microphone being put in place compensation mobile phone when using.So shown in Fig. 7-9, the axis by these two assemblies has generally been represented an axis, has departed from an angle from this axis wall 46.Meanwhile, antenna module 34 is parallel to wall 46, and with the identical relative angle deflection between upper and

lower component walls

50 and 52, and a side 50 relative with antenna 24 that makes assembly seems thicker.

Relation shown in the actual size of antenna module 34 and sidewall 50 and 52 relative angles with respect to inwall 70 are not restricted to, but can obtain relative position and size.These angles are to determine according to such requirement, all walls of antenna module are flushed with all walls of mobile phone, and a profile that does not exceed rear wall 14 is provided, but this is not requirement of the present invention.Using when of the present invention, an important just central axis 88 of antenna 24 departs from an angle with respect to wall 70, this bias usually with the axis of wall 46 and first surface or qualification in advance between bias.But, this situation is when drawing in Antenna Positioning to be taken place in recess 44 and when parallel with mobile phone for convenience's sake, but as recess 44 also along the back of mobile phone with an angle location, antenna 24 can suppose one with respect to the different angle of angle wall 70, that use with the position of setting up wall 46 then.That is to say that when this antenna module forwarded a curling position to, it was partly determined by the required placement angle of antenna 24 being used for giving the angle of central axis 88 location of antenna 24 with respect to wall 70, this day line parallel or be not parallel to wall 14.For the purpose of discussing, the inclination between wall 70 and the central axis 88 or drift angle is treated and identical to wall 46 and 12.

As shown in Figure 4, because

wall

46 and 70 is parallel to each other basically, so for the antenna 24 in the curling position that is arranged in recess 44, any drift angle between the vertical axis (or loud speaker/microphone axis) of a preliminary election of these walls and mobile phone is cancelled.That is to say, although the angle of wall 46 will be departed from antenna 24 from the rear wall of mobile phone 10, the cooperation angle compensation on the wall 70 and in recess 44, be aligned in the central axis 88 of the antenna 24 parallel with rear wall 14.But when antenna module 34 rotated, wall 70 no longer had the opposite effect to departing from of being given by wall 46.On the contrary, all angles of this two wall during turning begin each other mutually in addition to antenna axis 88 generation one even bigger departing from.

All as discussed above as can be seen from Figure 5 drift angles or inclination angle are to the influence of wall 40 and 70.Rotate a curling position when being 0 ° at antenna module, as can finding out from Fig. 4 and 6 (a), wall 46 and the 70 relative drift angles with respect to a predetermined handpiece axis (top discussed) is θ, and the relative drift angle of the central axis 88 of antenna 24 is 0 °.When about 180 ° of antenna module 34 rotations, after antenna 24 was positioned directly on the wall 18, the relative drift angle of the central axis 88 of this antenna 24 was 2 θ, was two wall deviation value sums.For any position between these two values, the relative drift angle that obtains is 2 θ and the angle of rotation product to 180 ° ratio.Those are familiar with those of ordinary skill in the art and are readily appreciated that how this extension to be turned over 180 °.The substrate of antenna 24 that like this, just causes being counted as antenna module 34 is around an operation and be parallel to second pivot, 90 rotations at

wall

46 and 70 interface between sidewall 20 and 22.This second pivot is substantially perpendicular to first pivot 40, to having given discussion above this.
