Description

PHASE SHIFTER IN WHICH A RORATION MEMBER IS COMBINED WITH A GUIDE MEMBER}

The present invention relates to a phase shifter, and more particularly, to a phase shifter that combines a rotation member and a guide member through a force transmission member arranged on an upper portion of a reflecting plate to reduce a loss due to friction.

The phase shifter is a device for distributing the power provided to the radiation element, that is, an element for varying the phase of the RF signal transmitted to the radiation element, and generally has a structure as shown in FIG. 1 below.

1 is a top view illustrating a conventional phase shifter, and FIG. 2 is a view schematically illustrating a bottom surface of the phase shifter of FIG. 1.

Referring to FIG. 1, a conventional phase shifter includes a dielectric substrate 100, a first line 102, a second line 104, an input line 106, an output line 108, a rotation shaft 110, and an arm part. Arm section 112 and guide member 114.

The dielectric substrate 100 is made of a dielectric material having a predetermined dielectric constant, and a ground plate is formed below the dielectric substrate 100.

The first line 102 is formed over the dielectric substrate 100 as a conductor, the ends of which are electrically connected to the first and second radiation elements.

The second line 104 is formed over the dielectric substrate 100 as a conductor, the ends of which are electrically connected to the third and fourth radiation elements.

Input line 106 receives the RF signal as a conductor. The received RF signal is output to the fifth radiation element through the first dielectric substrate region located below the output line 108 of the dielectric substrate 100 or is coupled to the rotary shaft 110 and then coupled to the dielectric substrate. Proceeding to the second dielectric substrate region located below the arm portion 112 of the 100. Here, a third line (not shown) that is a conductor is formed on the lower surface of the arm part 112. The RF signal propagated to the second dielectric substrate region is then coupled between the termination of the third line and the first and second lines 102 and 104 and then transmitted to the corresponding radiating elements.

The output line 108 outputs the RF signal itself to the first radiation element without changing the phase of the RF signal for the beam characteristic of the array antenna composed of the radiation elements as a conductor.

The rotating shaft 110 is coupled to the gear wheel 200 as shown in FIG. 2, and is connected to the arm 112 and the guide member 114 as shown in FIG. 1. Here, the gear wheel 200 rotates in response to the rotation of the gear worm 202, and as a result, the rotational force according to the rotation is transmitted to the arm 112 through the guide member 114. That is, the conventional phase shifter rotates the arm 112 by rotating the gear worm 202 a desired number of times in the forward or reverse direction to change the phase of the signals transmitted to the radiation elements.

Hereinafter, the coupling relationship of the phase shifter will be described in detail.

3 is a cross-sectional view illustrating the phase shifter of FIG. 1.

Referring to FIG. 3, the rotation shaft 110 is coupled to the gear wheel 200 and connected to the arm 112 and the guide member 114 while penetrating through the dielectric substrate 100.

The guide member 114 is connected to the rotation shaft 110 and rotates in response to the rotation of the rotation shaft 110, and includes a guide base member 114A, a side portion 114B, a support portion 114C, and a protrusion 114D.

Guide base member 114A is located on the upper surface of arm portion 112.

The support part 114C extends in the direction of the rotation axis 110 from the side part 114B, is located below the dielectric substrate 100, and is supported by the dielectric substrate 100.

The protrusion 114D protrudes from the guide base member 114A and is inserted into a portion of the arm 112 as shown in FIG. 3. As a result, the arm 112 is fixed to the guide member 114, and thus rotates together with the guide member 114 when the rotation shaft 110 rotates.

In short, the conventional phase shifter rotates the guide member 114 and the arm 112 by the desired length using the gear worm 202 and the gear wheel 200 to control the phase shift, and consequently the arm 112 ) Is rotated by the desired phase difference. However, when the gear worm 202 is rotated in the forward direction and then rotated in the reverse direction again in the phase shifter, the gear worm 202 may be damaged due to friction between the gear worm 202 and the gear wheel 200 and loss of force in the transmission process. There was a problem that a loss of two or more turns occurs until the rotational force is transmitted to the arm 112.

It is a first object of the present invention to provide a phase shifter for connecting the rotating member and the guide member through a force transmission member arranged on the upper portion of the reflecting plate so that the loss of force transmitted to the arm portion is reduced.

It is a second object of the present invention to provide a phase shifter for stably fixing a rotating member during phase change by using the fixing member.

In order to achieve the above object, the phase shifter arranged on the reflecting plate according to an embodiment of the present invention comprises a first rotation axis arranged through the reflecting plate;

A first guide member coupled to the first axis of rotation on a first surface of the reflector and extending in an outward direction from the first axis of rotation; A rotating member coupled to the first rotational shaft and having a body portion arranged to penetrate the reflecting plate and a rotation portion extending outwardly from the body portion on a second surface opposite to the first surface of the surfaces of the reflecting plate; And a force transmission member connecting the first guide member with at least one of the body portion and the first rotation shaft on the first surface of the reflector.

According to another embodiment of the present invention, a phase shifter arranged on a reflector includes: a rotation shaft arranged through the reflector; A guide member coupled to the rotating shaft on the first surface of the reflecting plate and extending in an outward direction from the rotating shaft; A rotating member engaged with the rotation shaft at a second surface of the reflecting plate opposite to the first surface; And a force transmission member connecting the rotation shaft and the guide member on the first surface of the reflection plate.

Since the phase shifter according to an embodiment of the present invention connects the guide member and the rotating member through the force transmission member, the loss of the force due to friction is reduced when the driving member is rotated in the forward direction and then rotated in the reverse direction again. There is an advantage that the rotational force according to the rotation of the rotating member is well transmitted to the arm portion. Here, the force transmission member is located on the surface where the guide member is located among the surfaces of the reflective plate, that is, the cutting plate is not cut in order to join the force transmission member and the guide member. As a result, the characteristics of the antenna do not change due to the coupling of the force transmission member and the guide member.

Since the phase shifter according to another embodiment of the present invention includes a fixing member for fixing the rotating member, there is an advantage that the rotating member can be stably fixed during operation when the phase shifter is operated.

In addition, the phase shifter according to another embodiment of the present invention can be easily coupled and separated by a plurality of sub-phase shifters by implementing the rotation axis in a separate type. Therefore, there is an advantage that the utilization of the phase shifter is increased and the convenience in use can be improved when the phase shifter is used.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 is a top view schematically illustrating a phase shifter according to a first embodiment of the present invention, and FIG. 5 is a cross-sectional view schematically illustrating the phase shifter of FIG. 4. 6 is a side view of the phase shifter of FIG. 4 in accordance with an embodiment of the present invention.

4 to 6, the phase shifter according to the present embodiment is a device connected to radiation elements (not shown) to vary the phase of signals transmitted to the radiation elements. , The first line 402, the second line 404, the input line 406, the output line 408, the rotation shaft 410, the arm section 412, the guide member 414, the rotation member 502. ) And force transmission member 504.

The dielectric substrate 400 is formed of a dielectric material having a predetermined dielectric constant on a first surface, for example, an upper surface, of the surfaces of the reflective plate 500. According to an embodiment of the present invention, a ground plate (not shown) may be formed on the bottom surface or the inside of the dielectric substrate 400.

In FIG. 5, the reflector 500 is illustrated in a planar shape, but may have a shape bent in a specific direction. Hereinafter, the first surface of the reflective plate 500 will be referred to as an upper surface, and the second surface opposite to the first surface of the surfaces of the reflective plate 500 will be referred to as a lower surface.

The first line 402 is formed on the dielectric substrate 400 as a conductor, for example, in a curved shape. Here, terminations of the first line 402 are electrically connected to some of the radiation elements (eg, first and second radiation elements), although not shown.

The second line 404 is formed on the dielectric substrate 400 as a conductor, for example, with a curved shape, the ends of which are electrically connected to some of the radiation elements (eg, third and fourth radiation elements). Connected.

According to one embodiment of the present invention, the second line 404 has an arc length that is less than the arc length of the first line 402, so that the second line 404 has a smaller phase change than the first line 402. Causes For example, while the phase of the signal propagated through the dielectric substrate region positioned below the first line 402 changes by 2θ, the signal propagates through the dielectric substrate region positioned below the second line 404. The phase may change by θ.

Although these lines 402 and 404 are not shown as having a specific shape in FIG. 4, the arc portion may have a comb pattern for a larger phase change. However, this pattern is not particularly limited.

Input line 406 receives the RF signal as a conductor. The received RF signal is output to the corresponding radiation element through the first dielectric substrate region located below the output line 408 of the dielectric substrate 400 or coupled at the rotation axis 410 and then coupled to the dielectric substrate 400. In operation 400, the second dielectric substrate is positioned under the third line (not shown) formed under the arm 412.

The output line 408 outputs the RF signal input as the conductor to the corresponding radiation element without changing the phase.

That is, the RF signal is output to the first radiating element of the radiating elements through the output line 408 without changing the phase. In addition, the RF signal travels through the second dielectric substrate region positioned below the third line after being coupled at the rotation shaft 410. Here, the signal propagated in the direction of the first line 402 of the signals coupled from the rotary shaft 410 is coupled between one end of the arm portion 412, that is, one end of the third line and the first line 402. Then, it is output to the second radiation element and the third radiation element of the radiation elements through the dielectric substrate region located below the first line 402. In addition, the signal propagated in the direction of the second line 404 of the signal coupled from the rotation axis 410 is coupled between the other end of the arm 412, that is, the other end of the third line and the second line 404, Then, it is output to the fourth radiation element and the fifth radiation element of the radiation elements through the dielectric substrate region positioned below the second line 404. As a result, the array antenna of the radiating elements has a predetermined beam pattern, and the beam pattern is changed in response to the phase change of the phase shifter.

The rotating shaft 410 is coupled to the rotating member 502 on the lower surface of the reflecting plate 500, and coupled to the arm 412 and the guide member 414 on the upper surface of the reflecting plate 500. Therefore, when the user rotates the rotating member 502 by the number of rotations corresponding to the specific value in order to change the phase by a specific value, the rotating shaft 410 is rotated in response to the rotation of the rotating member 502, Thereafter, the arm 412 and the guide member 414 rotate in response to the rotation of the rotation shaft 410.

A third line, which is a conductor, is formed on the lower surface of the arm portion 412.

The guide member 414 fixes the arm 412 while being connected to the rotation shaft 410. Accordingly, the rotational force of the rotation shaft 410 is transmitted to the arm portion 412 through the guide member 414, and as a result, the arm portion 412 rotates together with the guide member 414 by the transmitted rotational force.

This guide member 414 includes a guide base member 414A, a side portion 414B, a support 414C, a guide protrusion 414D, and a side support 414E, as shown in FIG.

Guide base member 414A is coupled to arm portion 412 at the upper surface of arm portion 412, and side portion 414B is positioned to the side of arm portion 412.

The support part 414C extends in the direction of the rotation axis 410 from the side part 414B and is positioned below the dielectric substrate 400 to be supported by the dielectric substrate 400. As a result, since the dielectric substrate 400 supports the guide member 414, the guide member 414 can maintain its current state without shaking.

The side protrusion 441E is positioned at the side of the arm 412 to fix the arm 412, and transmits a force provided through the rotation shaft 410 to the arm 412 to rotate the arm 412.

The guide protrusion 414D extends in the direction of the force transmission member 504 from the support portion 414C as shown in FIG. 5, and is inserted into the insertion portion of the force transmission member 504 and Combined. Of course, as long as the guide member 414 and the force transmission member 504 are coupled, it will be apparent to those skilled in the art that the method of coupling the guide protrusion 414D and the force transmission member 504 may be variously modified in addition to the above method. would.

When the guide member 414 and the force transmission member 504 are combined as described above, the rotational force generated by the rotation of the rotation member 502 is transmitted to the arm part 412 through the rotation shaft 410 and the guide member 414. It is also transmitted to the arm portion 412 through the force transmission member 504 and the guide member 414. Here, the force transmission member 504 is connected to the rotating member 502 and the guide member 414 on the upper surface of the reflecting plate 500 as shown in FIG.

According to another embodiment of the present invention, the rotation member 502 and the force transmission member 504 may be integrally implemented. In addition, although the force transmission member 504 is illustrated as being coupled to the rotation member 502 in FIG. 5, the force transmission member 504 may be coupled to the rotation shaft 410 instead of the rotation member 502.

In the above, the force transmission member 504 is coupled to the guide member 414 on the upper surface of the reflecting plate 500, but may be coupled to the guide member 414 on the lower surface of the reflecting plate 500. In this case, a specific portion of the reflecting plate 500 is cut, a specific hole is formed, the guide protrusion 414D of the guide member 414 extends to the lower surface of the reflecting plate 500 through the hole, and the reflecting plate ( The force transmission member positioned on the lower surface of the 500 is coupled to the guide protrusion 414D on the lower surface of the reflector plate 500. However, the formation of a hole in a portion of the reflector 500 may affect the characteristics of the antenna. Thus, the force transmission member 504 and the guide member 414 may be formed to prevent the hole from being formed. It is preferable to bond on the upper surface.

The rotating member 502 is an element for rotating the rotating shaft 410, for example, a gear wheel. In this case, the rotary member 502 rotates in response to the rotation of the gear worm in engagement with a drive member, for example a gear worm, as described below. That is, when a user rotates the gear worm in a specific direction using a motor or the like from the outside, the rotating member 502 rotates in response to the rotation of the gear worm, and rotates the rotation force according to the rotation shaft 410 and The guide member 414 and the arm 412 are transmitted through the force transmission member 504 to rotate the guide member 414 and the arm 412. Of course, the structure of the rotating member 502 and the drive member is not particularly limited as long as the rotating member 502 can provide a rotational force to the rotating shaft 410.

According to one embodiment of the present invention, the rotation member 502 may be fixed by a fixing member located on the bottom surface of the reflecting plate 500, although not shown in FIG. Detailed description thereof will be described later.

Hereinafter, the coupling relationship of each component in the phase shifter will be described in more detail with reference to FIG. 5.

As shown in FIG. 5, the rotating shaft 410 is connected to the rotating member 502 and is connected to the guide member 414 through the dielectric substrate 400.

The guide member 414 is a fitting base 414F and a tensioning part for fixing the arm 412 in addition to the guide base member 414A, the side portion 414B, the support portion 414C and the guide protrusion 414D, and the side protrusion 414E. (Tension section, 414G) further.

Since the fitting portion 414F fixes the arm portion 412 as shown in FIG. 5, the rotational force provided through the rotation shaft 410 can be better transmitted to the arm portion 412.

The support 414C is supported by the bottom surface of the dielectric substrate 400, and the guide protrusion 414D extends from the support 414C and engages with the force transmission member 504 as mentioned above.

The tension unit 414G assists a predetermined gap between the arm unit 412 and the dielectric substrate 400 to help the phase shifter achieve a desired phase value.

The rotation shaft 410 and the guide member 414 transmit the rotational force of the rotation member 502 to the arm portion 412.

Hereinafter, the phase shifter of the present invention is compared with the conventional phase shifter.

The conventional phase shifter rotates a gear wheel by controlling a gear worm, and transmits the rotational force according to the rotation of the gear wheel to the arm part through the rotation shaft and the guide member. Here, when the gear worm rotates in the forward direction and then rotates again in the reverse direction, the rotational force is greatly lost until the gear worm is transferred to the arm due to friction between the gear worm and the gear wheel and a loss in the force transmission process. As a result, the rotational force generated by the rotation of the gear worm was not sufficiently transmitted to the arm portion. As a result, the user tried to change the phase of the phase shifter by a certain angle by applying a specific rotational force, but could not change the phase by the desired angle due to the large loss of the rotational force.

On the other hand, the phase shifter of the present embodiment not only transmits the rotational force according to the rotation of the rotation member 502 to the arm portion 412 through the rotation shaft 410 and the guide member 414, but also the force transmission member 504 and the guide member ( It also passes to the arm portion 412 through 414. Of course, in the phase shifter of the present embodiment, when the rotating member 502 is rotated using the driving member, the arm member 412 may be moved to the arm part 412 due to friction between the driving member and the rotating member 502 and a loss in the transfer process. Loss of transmitted force occurs. However, the phase shifter of the present embodiment also transmits the rotational force to the arm portion 412 through the force transmission member 504 and the guide member 414, thereby reducing the loss of force than in the conventional phase shifter. For example, when the gear worm is rotated in the forward direction and then rotated in the reverse direction again, a loss of force of two or more rotations occurs in the conventional phase shifter, but a loss of force of one rotation or less occurs in the phase shifter of the present embodiment. That is, the phase shifter of the present embodiment has a reduced power loss than the conventional phase shifter, and thus can control the phase change more precisely. In addition, since the force transmitting member 504 connects the rotating member 502 and the guide member 414 on the upper surface of the reflecting plate 500, it is not necessary to cut the reflecting plate 500 so that the characteristics of the antenna can be kept constant. Can be.

Although the phase shifter of the present embodiment has been described as outputting five signals to corresponding radiating elements, the number of output signals may vary according to the characteristics of the antenna element to be implemented. In this case, the number and arrangement of the lines will change according to the output signal.

In the above, the guide protrusion 414D is formed in the support 414C of the guide member 414 and the guide protrusion 414D is inserted into the insertion portion of the force transmission member 504. However, according to another embodiment of the present invention, the guide protrusion may not be formed in the guide member, and the force transmission member may be formed in a 'b' shape. In this case, one end of the force transmission member is connected to the rotation member (or rotation shaft), the other end is inserted into the recess formed on the lower surface of the support of the guide member may be coupled to the force transmission member and the guide member. have. That is, the method of connecting the rotating member (or the rotating shaft) and the guide member may be variously modified as long as the force transmitting member connects the rotating member (or the rotating shaft) and the guide member.

7 is a view schematically illustrating a rotating member positioned below the reflector of FIG. 4 according to an embodiment of the present invention, and FIGS. 8 and 9 illustrate a method of fixing the rotating member according to an embodiment of the present invention. Figures shown.

Referring to FIG. 7, the rotating member 502 includes a first sub rotating part 502A, a second sub rotating part 502B, and a body part 502C positioned under the reflecting plate 500. Here, the rotating shaft 410 is coupled to the rotating member 502 in a state of being inserted into the rotating member 502 as shown in FIG.

The first sub-rotation portion 502A extends outwardly from the body portion 502C and has a circular shape, for example. Here, the outer line of the first sub rotating part 502A has a smooth curve as shown in FIG. 7. Of course, the outer line of the first sub-rotation part 502A may have a sawtooth shape like the second sub-rotation part 502B.

The second sub-rotation portion 502B extends in the outward direction from the body portion 502C and has a circular shape. In addition, the outer line of the second sub-rotation part 502B has a sawtooth shape.

The driving member 700 is engaged with the rotating member 502 of this structure. In detail, the drive member 700 meshes with the second sub-rotation part 502B, as shown in FIG. 8 (B). As a result, when the user rotates the drive member 700 using the remote control device from the outside, the second sub-rotator 502B is driven by the drive member 700 and the second sub-rotator 502B. Rotate in response to the rotation of 700). Here, considering only the generation of the rotational force of the rotation member 502, the rotation member 502 may be made of only the second sub-rotation portion 502B. However, the two sub-rotation parts 502A and 502B are formed in the rotation member 502 in order to stably fix the rotation member 502 to the fixing member 800 as described later. That is, in the phase shifter of the present invention, the rotation member 502 is formed with at least one sub-rotation part.

Hereinafter, the coupling form of the driving member 700 and the rotation member 502 will be described with reference to FIGS. 8 and 9.

As shown in FIGS. 8 and 9, the rotating member 502 is fixed by the fixing member 800 at the bottom of the reflecting plate 500.

The driving member 700 is inserted into and fixed to the driving member inserting portion 800C formed in the fixing member 800. However, the driving member insert 800C is formed in the fixing member 800 at a position that allows the driving member 700 to engage with the second sub-rotating portion 502B of the rotating member 502. As a result, the rotating member 502 rotates in response to the rotation of the drive member 700. In addition, since the rotating member 502 is fixed by the fixing member 800 as shown in FIG. 8, when the phase shifter changes phase, the rotating member 502 may be stably fixed to rotate by a desired phase angle. .

Hereinafter, the coupling process of the driving member 700, the rotation member 502, and the fixing member 800 will be described in detail.

Referring again to FIG. 9, the fixing member 800 includes a body portion 800A, a close contact portion 800B, and a driving member inserting portion 800C.

The body portion 800A is divided into two regions as shown in FIG. 9, and as a result, a specific space 900 is formed in the body portion 800A.

In this case, the rotating member 502 proceeds in the direction of the arrow and is fixed to the fixing member 800. Specifically, the rotating member 502 is positioned such that the body portion 800A is positioned between the sub-rotating portions 502A or 502B as shown in FIG. 8B (cut along the line I-I '). It is coupled to the fixing member 800. As a result, the rotating member 502 is supported by the fixing member 800 which is stably fixed to the reflecting plate 500, that is, the rotating member 502 is primarily fixed to the fixing member 800.

In addition, when the rotating member 502 is fixed to the fixing member 800, the second rotating member 502B of the rotating member 502 is in close contact with the contact portion 800B as shown in Fig. 8A. . Therefore, after the rotation member 502 is fixed by the fixing member 800, it is not pushed out by the contact part 800B.

Next, the driving member 700 is inserted into the driving member insertion portion 800C of the fixing member 800, and as a result, the driving member 700 is fixed by the fixing member 800 in the rotating member 502 Can be rotated.

In short, in the phase shifter of the present invention, since the driving member 700 and the rotating member 502 are stably fixed by the fixing member 800, the rotational force of the driving member 700 can be accurately transmitted to the rotating member 502. Can be. Therefore, the phase change at the time of phase shift of the phase shifter can be precisely controlled.

10 is a perspective view illustrating a phase shifter according to a second exemplary embodiment of the present invention, and FIG. 11 is a cross-sectional view illustrating the phase shifter of FIG. 10 according to an exemplary embodiment of the present invention.

Referring to FIG. 10, the phase shifter of the present embodiment may include a first dielectric substrate 1000, a second dielectric substrate 1002, a rotation shaft 1004, a first arm portion 1006, a first guide member 1008, and a second An arm portion 1010 and a second guide member 1012. That is, the phase shifter of the present embodiment implements two sub phase shifters as one. Here, the sub phase shifters operate as one phase shifter, respectively.

The first dielectric substrate 1000 has a first dielectric constant, and predetermined lines are formed on an upper surface thereof.

The second dielectric substrate 1002 has a second dielectric constant, and predetermined lines are formed on an upper surface thereof. Preferably, the second dielectric constant is substantially the same as the first dielectric constant.

The rotating shaft 1004 penetrates through the first dielectric substrate 1000 and the second dielectric substrate 1002 as shown in FIG. 10, and guides 1008 and 1012 a rotational force according to the rotation of the rotating member (not shown). To pass). The rotating shaft 1004 may be formed as one member, or may be formed as a separate type by combining sub-rotating shafts.

The first arm portion 1006 is connected to the rotating shaft 1004 and rotates in response to the rotation of the rotating shaft 1004. Here, a specific line which is a conductor is formed below the first arm portion 1006.

The second arm 1010 is connected to the rotation shaft 1004 and rotates in response to the rotation of the rotation shaft 1004. Here, a specific line that is a conductor is formed below the second arm 1010.

The first guide member 1008 fixes the first arm portion 1006 and transmits the rotational force provided through the rotation shaft 1004 to the first arm portion 1006.
