  Then, in a state where the large-diameter portion 93pw of the vertical pin and the large-diameter portion 93pw of the horizontal pin completely pass through the vertical pin hole and the horizontal pin hole, respectively (hereinafter, also referred to as a passing state), the small diameter portion 93pn. The base 22b, that is, the polarization processor 161 is rotated about the z-axis as a rotation axis until the... Contacts the opposite end of the elongated hole 22s from the pin hole 22p.

  For example, the elongated hole 22s defines the positional relationship between the processing-side connectors 42v and 42h and the communication device 131 in the circumferential direction of the hole 22h included in the bayonet structure in the first fixed portion 21 as a positioning portion.

  More specifically, the positions of the processing-side connectors 42v and 42h with respect to the elongated holes 22s are determined by the processing-side connectors 42v and 42h in a state after the polarization processor 161 is rotated (hereinafter, also referred to as a post-rotation state). It is a position facing the communication device side connectors 43v and 43h, respectively. Specifically, for example, in a configuration in which the processing-side connectors 42v and 42h, the communication-device-side connectors 43v and 43h, and the vertical pins and the horizontal pins are arranged in the horizontal direction, the processing-side connectors 42v and 42h, The communication side connectors 43v and 43h, the vertical pin, the horizontal pin, and the two elongated holes 22s are located on the same plane.

  Then, by bringing the bayonet male terminal 93 and the bayonet female terminal 22 close to each other without changing the positional relationship between the base portion 22b and the communication device 131 in the circumferential direction of the hole 22h (hereinafter, also referred to as circumferential positional relationship), the claw portion is formed. 93m (see FIG. 5) and the protruding portion 22m (see FIG. 9) pass through the non-projecting space 22n and the non-claw space 93n, respectively.

  When the first end surface 93ba of the bayonet male terminal 93 is in contact with the second end surface 22bb of the base portion 22b (hereinafter, also referred to as a contact state), the operation of rotating the handle portion 22rk in the fixing direction Dr1 is performed. The claw portion 93m is inserted into the groove 22g, and the claw portion 93m is press-fitted between the second end surface 22bb and the protruding portion 22m and fixed. As a result, the polarization processor 161 and the communication device 131 are firmly connected without play.

  The fixing direction Dr1 is not limited to the clockwise direction toward the second end surface 22bb, but may be a counterclockwise direction toward the second end surface 22bb. However, it is preferable that the fixing direction Dr1 coincides with the direction in which the base portion 22b, that is, the polarization processor 161 is rotated such that the small-diameter portion 93pn fits into the elongated hole 22s for the following reason (see FIGS. 5 and 9). .

  That is, when the direction in which the handle portion 22rk is rotated during fixing and the direction in which the polarization processor 161 is rotated so that the small-diameter portion 93pn fits into the elongated hole 22s match, when the handle portion 22rk is rotated, the small-diameter portion is rotated. This is because it is possible to prevent the polarization processor 161 from being erroneously rotated in a direction in which 93 pn exits from the elongated hole 22s.

  The processing-side connectors 42v and 42h respectively pass two types of polarized waves when the first fixed unit 21 is connected to the communication device 131.

  Specifically, in the contact state, for example, the first end of the processing-side connector 42v and the first end of the processing-side connector 42h are connected to the communication device-side connectors 43v and 43h by being fitted respectively.

  More specifically, the protrusion 42p of the processing-side connector 42v is fitted with the recess 43m of the communication-side connector 43v. In addition, the protrusion 42p of the processing-side connector 42h is fitted with the recess 43m of the communication-side connector 43h.

  Thus, the processing-side connectors 42v and 42h are electrically connected to the communication-side connectors 43v and 43h, respectively.

  For example, in the post-rotation state, the first end of the processing-side connector 42 and the communication-device-side connector 43 may face each other at a closed position.

  Even in such a case, the processing-side connector 42 can be moved in a direction orthogonal to the connection direction of the bayonet female terminal 22, so that the first end of the processing-side connector 42 and the communication device-side connector 43 By moving the processing-side connector 42 so as to face each other at an appropriate position, the convex portion 42p and the concave portion 43m can be fitted well.

  Further, the configuration in which the tapered inner surface 43mj is formed in the concave portion 43m of the communication device side connector 43 increases the allowable error of the position where the first end of the processing side connector 42 and the communication device side connector 43 are fitted well. can do.

[Length of small diameter part 93 pn]
The length of the small-diameter portion 93pn is, for example, such that the processing-side connectors 42v and 42h and the communication-device-side connectors 43v and 43h do not contact each other in the passing state.

  This makes it possible to transition from the passing state to the post-rotation state while preventing the processing-side connector 42 and the communication device-side connector 43 from contacting each other.

[Retaining function]
For example, even when the polarization processor 161 is connected to the communication device 131, the handle 22rk rotates, and the claw 93m and the protruding portion 22m can pass through the non-protruding space 22n and the non-claw space 93n, respectively. In some cases.

  Even in such a state, for example, the long hole 22s, as a retaining portion, restricts movement that separates the first fixed portion 21 and the communication device 131 without changing the circumferential positional relationship.

  Specifically, even if the bayonet male terminal 93 and the bayonet female terminal 22 are separated without changing the circumferential positional relationship, the claw 93m and the protrusion 22m pass through the non-projection space 22n and the non-claw space 93n, respectively. The large diameter portion 93pw cannot pass through the long hole 22s.

  With such a configuration, even in the above state, the polarization processor 161 can be prevented from falling off from the communication device 131 unless the circumferential positional relationship is changed.

[Fixing of the reflector 1]
Referring to FIGS. 3, 14 and 16, reflecting portion 1 is fixed to polarization processor 161 by coupling bayonet female terminal 2 and bayonet male terminal 53 in second fixing portion 51.

  More specifically, by inserting the first waveguide 61 from the first end 61Ea side into the hole 1h (see FIG. 3) in the reflecting portion 1 and the hole 2h (see FIG. 14) in the bayonet female terminal 2 (see FIG. 14). In this state, the bayonet female terminal 2 and the bayonet male terminal 53 face each other.

  In this state, the claw 53m (see FIG. 16) and the protrusion 2m (see FIG. 14) pass through the non-projection space 2n and the non-claw space 53n, respectively, and the pin 53p of the bayonet male terminal 53 is connected to the bayonet female terminal 2. The bayonet male terminal 53 and the bayonet female terminal 2 are brought close to each other so as to be inserted into the pin hole 2p.

  When the first end surface 53ba of the bayonet male terminal 53 comes into contact with the second end surface 2bb of the base portion 2b, the base portion 2b, that is, the reflector main body 1b is rotated about the z-axis as a rotation so that the small-diameter portion 53pn of the pin 53p is elongated. Insert

  Then, by performing an operation of rotating the handle portion 2rk in the fixing direction Dr2 (see FIG. 14), the claw portion 53m is inserted into the groove 2g, and the claw portion 53m is press-fitted between the second end surface 2bb and the protruding portion 2m. Is fixed. Here, the fixing direction Dr2 is, for example, a clockwise direction toward the second end face 2bb. As a result, the reflection unit 1 is connected to the second fixing unit 51 without looseness. At this time, as shown in FIG. 1, the first waveguide 61 penetrates the reflecting section 1.

  The fixing direction Dr2 is not limited to the clockwise direction toward the second end surface 2bb, but may be a counterclockwise direction toward the second end surface 2bb. However, for the same reason as the fixing direction Dr1, the fixing direction Dr2 preferably coincides with the direction in which the base portion 2b, that is, the reflecting mirror main body 1b is rotated so that the small diameter portion 53pn fits into the elongated hole 2s (FIG. 14). To FIG. 16).

The first protection member 62 partitions, for example, the internal space of the first waveguide 61 into two internal spaces.

  The second waveguide 31 includes, for example, a second protection member 32. More specifically, the second protection member 32 is made of, for example, a dielectric, and contacts the inner wall 33 of the second waveguide 31 along the circumferential direction. The second protection member 32 partitions, for example, the internal space of the second waveguide 31 into two internal spaces.

  Specifically, the first protection member 62 and the second protection member 32 are formed in a solid cylindrical shape using, for example, PTFE (polytetrafluoroethylene).

  Note that the first protection member 62 and the second protection member 32 are not limited to solid, and may have a mesh structure capable of preventing intrusion of foreign matter having a size to be excluded. Further, the shapes of the first protection member 62 and the second protection member 32 are not limited to the columnar shapes, but may be other shapes as long as they are in contact with the corresponding inner walls along the circumferential direction. Further, the material of the first protection member 62 and the second protection member 32 is not limited to PTFE, but may be another material as long as it is a dielectric.

  Referring to FIG. 18, second waveguide 31 includes an inner part 31A and an outer part 31B. The outer portion 31B has an opening 34c at an end opposite to the primary radiator 101, that is, at a second end 31Ea. The inside portion 31A and the outside portion 31B are cylindrical members made of metal.

  In the outer portion 31B, on the opening 34c side, for example, a socket portion 34 for connecting to the first waveguide 61 is provided. The socket section 34 is described in, for example, Non-Patent Document 2 (Yoshida Machinery Co., Ltd., “TS Series for Medium / Low Pressure, General-purpose, Both Ways Open”, [online], [Search April 11, 2016], Internet < URL: http://www.yosida-mfg.co.jp/contents/TS-J.pdf>).

  The inner part 31A forms a part of the second waveguide 31. The outer portion 31B contacts, for example, all of the outer surface of the inner portion 31A to form another tube of the second waveguide 31.

  On the inner surface of the outer portion 31B, there are provided reduced diameter portions 36a, 36b, and 36c that reduce the diameter in three stages from the opening portion 34c toward the primary radiator 101. The reduced diameter portions 36b and 36c have annular surfaces along a direction perpendicular to the extension axis of the second waveguide 31.

  On the inner surface of the outer portion 31B, on the side opposite to the opening 34c with respect to the reduced diameter portion 36c, a cylindrical constant diameter portion 37 is provided.

  The inner portion 31A is provided between the reduced diameter portion 36c and the opening 34c. The inner portion 31A has substantially the same inner diameter as the inner diameter of the equal diameter portion 37, and is screwed and connected to the inner surface of the outer portion 31B at the outer periphery. The inner portion 31A has a side surface 31Ab facing the reduced diameter portion 36c with the second protection member 32 interposed therebetween, and a side surface 31Aa facing the first waveguide 61.

  The second protection member 32 is sandwiched, for example, between the inner portion 31A and the outer portion 31B.

  More specifically, the inner portion 31A and the outer portion 31B are screwed together, and the inner portion 31A is tightened with respect to the outer portion 31B, so that the second protection member 32 has a reduced diameter portion 36c and a side surface 31Ab. It is held in contact.

  The outer diameter of the second protection member 32 is, for example, smaller than the outer diameter of the inner portion 31A and larger than the inner diameter of the inner portion 31A.

  That is, it is preferable that the second protection member 32 is in contact with the entire circumference of the inner wall 33 of the second waveguide 31.

  The first waveguide 61 includes an inner part 61A and an outer part 61B. The outer portion 61B has an opening 64c at an end opposite to the communication device 131, that is, at a first end 61Ea. The inner portion 61A and the outer portion 61B are cylindrical members made of metal.

  In the outer portion 61B, a plug portion 64 for connecting to, for example, the second waveguide 31 is provided on the opening 64c side. More specifically, the plug portion 64 has, for example, a coupling structure according to the description of Non-Patent Document 2, and is detachably connected to the socket portion 34. The plug portion 64 can be inserted into the inside of the socket portion 34 from the opening portion 34c of the socket portion 34, for example.

  The inner portion 61A forms a part of the first waveguide 61. The outer portion 61B contacts all of the outer surface of the inner portion 61A to form another tube of the first waveguide 61.

  On the inner surface of the outer portion 61B, there is provided a reduced diameter portion 66a that reduces the diameter by one step from the opening 64c toward the communication device 131. The reduced diameter portion 66a has an annular surface along a direction perpendicular to the extension axis of the first waveguide 61.

  On the inner surface of the outer portion 61B, on the side opposite to the opening 64c with respect to the reduced diameter portion 66a, a cylindrical equal diameter portion 67 having an inner diameter substantially equal to the inner diameter of the equal diameter portion 37 is provided.

  The inner portion 61A is provided between the reduced diameter portion 66a and the opening 64c. The inner portion 61A has substantially the same inner diameter as the inner diameter of the equal diameter portion 67, and is screwed and connected to the inner surface of the outer portion 61B at the outer periphery.

  The inner portion 61A has a side surface 61Ab facing the reduced diameter portion 66a with the first protection member 62 interposed therebetween, and a side surface 61Aa facing the second waveguide 31. The thickness of the inner portion 61A, that is, the distance between the side surfaces is, for example, the same as the thickness of the inner portion 31A.

  The first protection member 62 is sandwiched, for example, between the inner portion 61A and the outer portion 61B.

  More specifically, the inner portion 61A and the outer portion 61B are screwed together, and the inner portion 61A is tightened with respect to the outer portion 61B, so that the first protection member 62 has a reduced diameter portion 66a and a side surface 61Ab. It is held in contact.

  The outer diameter of the first protection member 62 is, for example, smaller than the outer diameter of the inner portion 61A and larger than the inner diameter of the inner portion 61A.

  That is, it is preferable that the first protection member 62 is in contact with the entire circumference of the inner wall 63 of the first waveguide 61.

  Referring to FIGS. 18 and 19, plug portion 64 is inserted into opening 34c of second waveguide 31 into socket portion 34, and first waveguide 61 and second waveguide 31 are inserted. Can be connected. More specifically, in the connected state, the side surface 31Aa of the inner portion 31A of the second waveguide 31 and the side surface 61Aa of the inner portion 61A of the first waveguide 61 are in contact with each other.

  The second protection member 32 and the first protection member 62 are provided at intervals based on the wavelength of a radio wave to be transmitted, for example, in a connected state.

  Specifically, the distance d1 between the second protection member 32 and the first protection member 62 is substantially equal to the guide wavelength λg of the radio wave to be transmitted in the second waveguide 31 and the first waveguide 61. The distance is 1/4 times. Here, the value of the in-tube wavelength λg is calculated by, for example, Equation 3 · in page 74 of Non-patent Document 3 (Gensaburo Kuraishi, “Example / Exercise Microwave Circuit”, Tokyo Denki University Press, March 30, 1983). 42.

  The distance d1 is not limited to a distance obtained by substantially multiplying the guide wavelength λg by １ ／, but may be a distance obtained by multiplying the guide wavelength λg by approximately (１ ／ + n). Here, n is an integer greater than or equal to zero. More specifically, the distance d1 is, for example, λg × (１ ／ + n) ± λg / 8, and preferably λg × (１ ／ + n) ± λg / 16.

  Also, unlike the case shown in FIG. 19, when the inner diameter of the waveguide is not constant between the second protection member 32 and the first protection member 62, the distance d1 is equal to the distance between the second protection member 32 and the first protection member 62. The distance may be approximately 1/4 times the net tube wavelength between the protective member 62 and the protective member 62.

  Specifically, when the inner diameter of the inner part 61A and the inner diameter of the inner part 31A are different, the thickness of the inner part 61A and the thickness of the inner part 31A are, for example, approximately １ ／ times the guide wavelength in the inner part 61A. The length is set to be approximately 1/8 times the guide wavelength in the inner portion 31A.

  With such a configuration, the interference between the radio wave reflected by the second protection member 32 and the radio wave reflected by the first protection member 62 can be approximated to destructive interference, so that protection against degradation of the VSWR and the like can be achieved. Disturbance of the propagation characteristic of the radio wave by the member can be suppressed.

  Although the first waveguide 61 and the second waveguide 31 according to the first embodiment of the present invention have a cylindrical shape, the present invention is not limited to this. At least one of the first waveguide 61 and the second waveguide 31 may be a waveguide having a cross-sectional shape other than a circle such as a rectangular waveguide as long as it is hollow.

  The processing-side connector 42 according to the first embodiment of the present invention is a plug having a convex portion 42p that fits into the concave portion 43m of the communication device-side connector 43, but is not limited to this. Absent. The processing-side connector 42 may be a receptacle having a recess 43m.

  Further, in the polarization processor according to the first embodiment of the present invention, the first fixing portion 21 has the configuration having the bayonet female terminal 22, but is not limited thereto. The first fixing portion 21 may have a configuration having a bayonet male terminal.

  Further, in the polarization processor according to the first embodiment of the present invention, the second fixing portion 51 has the configuration having the bayonet male terminal 53, but the present invention is not limited to this. The second fixing portion 51 may have a configuration having a bayonet female terminal.

  In addition, the first protection member 62 according to the first embodiment of the present invention is configured to partition the internal space of the first waveguide 61 into two internal spaces. It is not limited to. The first protection member 62 is provided as a lid at the first end 61Ea of the first waveguide 61 without dividing the internal space of the first waveguide 61 into two internal spaces. Is also good.

  Further, the second protection member 32 according to the first embodiment of the present invention is configured to be provided so as to partition the internal space of the second waveguide 31 into two internal spaces. It is not limited to. The second protection member 32 is provided as a lid at the second end 31Ea of the second waveguide 31 without dividing the internal space of the second waveguide 31 into two internal spaces. Is also good.

  Further, the communication device according to the first embodiment of the present invention is configured to transmit and receive radio waves, but is not limited to this. The communication device 131 may be dedicated to transmission or reception of radio waves. When the communication device 131 is dedicated to transmission, the separation / combination unit 60 combines two types of polarized waves. On the other hand, when the communication device 131 is dedicated to reception, the separation / combination unit 60 separates two types of polarization.

  By the way, in the waveguides for coaxial antennas described in Patent Documents 1 and 2, it is difficult to transmit a multi-polarized radio wave. Conceivable. When using double polarization, for example, two connectors are provided in the communication device.

  For example, when the antenna and the communication device are separately fixed, the size of the entire antenna device is increased, so that the installability of the antenna device is deteriorated. Further, the cable connecting each connector and the waveguide in the communication device may be long. In such a case, the attenuation of the radio wave in the cable increases, which is not preferable. That is, there is a need for a technique for reducing the size of an entire antenna device using a waveguide.

  On the other hand, in the polarization processor according to the first embodiment of the present invention, the separation / combination unit 60 includes the first waveguide 61 connectable to the second waveguide 31, It is possible to separate and / or combine the types of polarization. The first fixed unit 21 has a bayonet structure including a hole 22h through which two types of polarized waves transmitted between the separation / combination unit 60 and the communication device 131 pass, and is detachably connected to the communication device 131. The processing-side connectors 42h and 42v allow the first fixed unit 21 to pass the two types of polarized waves while the first fixed unit 21 is connected to the communication device 131, and the first fixed units to pass the polarized waves in parallel to each other. 21 and is electrically connected to the separation / combination unit 60. The second fixing portion 51 has a bayonet structure including a hole 53h through which the first waveguide 61 included in the separation / combination portion 60 penetrates. It is detachably connected to a reflector 1 for reflecting polarized waves.

  As described above, the configuration in which the reflection unit 1, the second waveguide 31, and the communication device 131 are detachably connected to the polarization processor 161 is compared with a case where the antenna unit 151 and the communication device 131 are separately fixed. Since each part can be integrated, the entire antenna device 301 can be made compact. Thereby, the installation property of the antenna device 301 can be improved. In addition, due to the configuration in which two types of polarized waves pass through the hole 22h included in the bayonet structure of the first fixed portion 21, for example, the processing-side connectors 42v connected to the communication-side connectors 43v and 43h of the communication device 131, respectively. , 42h and the separation / combination unit 60, the length of the coaxial cables 44v, 44h can be reduced, so that the attenuation of radio waves in the coaxial cables 44v, 44h can be further suppressed. In addition, since the reflector 1 and the second waveguide 31 are directly fixed to the polarization processor 161, it is possible to prevent the positional relationship between the reflector 1 and the second waveguide 31 from becoming abnormal. As a result, deterioration of antenna performance can be prevented.

  In the polarization processor according to the first embodiment of the present invention, the communication device 131 includes communication device connectors 43v and 43h provided side by side. The processing-side connectors 42v and 42h protrude toward the communication device 131 and are provided side by side. The processing-side connectors 42v and 42h are of a push-on type which are detachably connected to the communication device-side connectors 43v and 43h by mutual pushing and pulling-out operations.

  As described above, the configuration using the push-on type processing-side connector 42 that facilitates the electrical connection and disconnection between the processing-side connectors 42v and 42h and the communication device-side connectors 43v and 43h has a bayonet structure. Mechanically good attachment / detachment of the first fixed part 21 and the communication device 131 and good electrical connection between the processing-side connector 42 and the communication-device-side connector 43 can be achieved.

  Further, in the polarization processor according to the first embodiment of the present invention, the processing-side connector 42 has a convex portion 42p that fits into the concave portion 43m of the communication-device-side connector 43.

  As described above, for example, the configuration using the processing-side connector 42 that is fitted with the communication-side connector 43 provided with the concave portion 43m generally used in the communication device 131 makes it possible to electrically connect with the standard communication device 131. Can be connected well.

  Further, in the polarization processor according to the first embodiment of the present invention, the recess 43m has an inner surface 43mj whose inner diameter decreases as the distance from the opening surface 43mc increases.

  With such a configuration, when making electrical connection between the processing-side connector 42 and the communication-device-side connector 43, the projection 42p and the recess 43m can be easily fitted.

  In the polarization processor according to the first embodiment of the present invention, the processing-side connector 42 is movable along a direction orthogonal to the connection direction of the bayonet structure in the first fixed part 21. .

  With such a configuration, for example, the attachment position of the processing-side connector 42 varies, so that the processing-side connector 42 and the communication device-side connector 43 are displaced when the first fixed portion 21 and the third fixed portion 91 are connected. Even if they face each other, the processing-side connector 42 can be easily moved so that the processing-side connector 42 and the communication device-side connector 43 face each other at an appropriate position.

  In the polarization processing device according to the first embodiment of the present invention, the elongated hole 22s serves as a positioning portion, and the processing-side connector 42v in the circumferential direction of the hole 22h included in the bayonet structure in the first fixed portion 21. , 42h and the communication device 131 are defined.

  With such a configuration, the processing-side connectors 42v and 42h can be positioned at the correct positions in the circumferential direction with respect to the communication device 131, so that, for example, the processing-side connector 42 and the communication device-side connector 43 can be easily positioned at appropriate positions. Can be opposed.

  Further, in the polarization processor according to the first embodiment of the present invention, the elongated hole 22s serves as a retaining portion, and the first hole 22h in the circumferential direction of the hole 22h included in the bayonet structure in the first fixed portion 21. Movement that separates the first fixed part 21 and the second waveguide 31 without changing the positional relationship between the fixed part 21 and the communication device 131 is limited.

  With such a configuration, it is possible to prevent the polarization processor 161 from easily falling off the communication device 131.

  Further, in the polarization processor according to the first embodiment of the present invention, the first fixing part 21 has a female bayonet structure.

  With such a configuration, the bayonet structure at the connection destination of the first fixing portion 21 can be, for example, generally a small male type, so that it is possible to prevent the workability at the time of connection from being deteriorated.

  Further, in the antenna device according to the first embodiment of the present invention, the separation / combination unit 60 includes the first waveguide 61 and performs at least one of separation and combination of two types of polarized waves. Is possible. The first fixed unit 21 has a bayonet structure including a hole 22h through which two types of polarized waves transmitted between the separation / combination unit 60 and the communication device 131 pass, and is detachably connected to the communication device 131. The processing-side connectors 42v and 42h allow the first fixed unit 21 to pass the two types of polarized waves when the first fixed unit 21 is connected to the communication device 131, and to allow the first fixed unit 21 to pass in parallel with each other. 21 and is electrically connected to the separation / combination unit 60. The reflector 1 reflects two types of polarized waves. The second fixing portion 51 has a bayonet structure including a hole 53h through which the first waveguide 61 penetrates, and is detachably connected to the reflecting portion 1 on the opposite side of the first fixing portion 21. The second waveguide 31 has a first end 31 </ b> Eb connected to the primary radiator 101 and a first waveguide on the side opposite to the first fixed part 21 with respect to the second fixed part 51. 61 and a second end 31Ea that can be connected.

  As described above, the configuration in which the reflection unit 1, the second waveguide 31, and the communication device 131 are detachably connected to the polarization processor 161 is compared with a case where the antenna unit 151 and the communication device 131 are separately fixed. Since each part can be integrated, the entire antenna device 301 can be made compact. Thereby, the installation property of the antenna device 301 can be improved. In addition, due to the configuration in which two types of polarized waves pass through the hole 22h included in the bayonet structure of the first fixed portion 21, for example, the processing-side connectors 42v connected to the communication-side connectors 43v and 43h of the communication device 131, respectively. , 42h and the separation / combination unit 60, the length of the coaxial cables 44v, 44h can be reduced, so that the attenuation of radio waves in the coaxial cables 44v, 44h can be further suppressed. In addition, since the reflector 1 and the second waveguide 31 are directly fixed to the polarization processor 161, it is possible to prevent the positional relationship between the reflector 1 and the second waveguide 31 from becoming abnormal. As a result, deterioration of antenna performance can be prevented.

  Further, the antenna device according to the first embodiment of the present invention further includes a first protection member 62 made of a dielectric, which is in contact with the inner wall 63 of the first waveguide 61 along the circumferential direction, A second protection member made of a dielectric and in contact with an inner wall of the second waveguide in a circumferential direction;

  With such a configuration, even when storage, transportation, connection, and the like are performed in a state where the first waveguide 61 and the second waveguide 31 are separated from each other, foreign matter enters the internal space of the waveguide. Can be suppressed. As a result, it is possible to prevent the radiation characteristics and performance of the antenna device 301 from deteriorating.

  In the antenna device according to the first embodiment of the present invention, the first protection member 62 and the second protection member 32 are connected to the first waveguide 61 and the second waveguide 31. In this state, the intervals are provided based on the wavelength of the radio wave to be transmitted.

  As described above, by providing these protection members at appropriate intervals, the amplitude of the radio wave reflected by the first protection member 62 and the amplitude of the radio wave reflected by the second protection member 32 can be canceled. Therefore, disturbance of the propagation characteristics of the radio wave due to the protection member such as deterioration of the VSWR can be suppressed while protecting the internal space of the waveguide.

[Modification of Guide 93g]
FIG. 25 is a diagram of a communication device according to the second embodiment of the present invention as viewed from above.

  Referring to FIG. 25, in a modified example of guide portion 93g, two crank grooves 93gc are provided instead of two grooves 93gg, as compared with guide portion 93g shown in FIG.

  More specifically, the connection groove 93gcc, the rotation guide groove 93gcb, and the introduction groove 93gca are formed in the crank groove 93gc in order from the opposite side of the opening surface 93ga.

  The connection groove 93gcc is provided at the same position as the groove 93gg shown in FIG. 21, is shorter than the length of the groove 93gg, and is connected to the end face of the guide 93g on the side of the base 93b.

  The introduction groove 93gca is provided at a position shifted from the groove 93gg shown in FIG. 21 in, for example, a clockwise direction (hereinafter, also referred to as a first direction) when the guide portion 93g is viewed from the opening surface 93ga side. It is shorter than the length of 93 gg, and is connected to the end face on the opposite side of the base portion 93b with respect to the guide portion 93g.

  The rotation guide groove 93gcb is connected to the connection groove 93gcc, is connected to the introduction groove 93gca, and is formed on the outer peripheral surface of the guide portion 93g along the circumferential direction. The width of the rotation guide groove 93gcb is slightly larger than the length of the projection 22c in the z-axis direction. The distance d2 between the rotation guide groove 93gcb and the end surface of the guide portion 93g on the base portion 93b side will be described later.

  Referring to FIGS. 23 and 25, when connecting bayonet female terminal 22 and bayonet male terminal 93, processing-side connectors 42v and 42h are opposed to communication-device-side connectors 43v and 43h, respectively.

  The bayonet male terminal 93 and the bayonet female terminal 22 are brought close to each other until the projection 22c is fitted into the rotation guide groove 93gcb (hereinafter, also referred to as a rotatable state).

  The base portion 22b is rotated in the direction opposite to the first direction with respect to the guide portion 93g until the convex portion 22c contacts the end on the side of the connection groove 93gcc with respect to the rotation guide groove 93gcb.

  Then, the bayonet male terminal 93 and the bayonet female terminal 22 are brought close to each other while the connection groove 93gcc and the projection 22c are fitted to each other, and brought into a contact state.

  Here, the distance d2 is, for example, such a distance that the processing-side connectors 42v and 42h and the communication-device-side connectors 43v and 43h do not contact each other in a rotatable state.

The positional relationship between 43v, 43h and the communication device 131 is defined.

  With such a configuration, the processing-side connector 42 can be positioned at a correct position in the circumferential direction with respect to the communication device 131. Therefore, for example, the processing-side connector 42 and the communication device-side connector 43 can be easily opposed to each other at an appropriate position. Can be done.

  Further, in the polarization processor according to the second embodiment of the present invention, the convex portion 22c serves as a retaining portion and is formed in the first fixing portion 21 in the circumferential direction of the hole 22h included in the bayonet structure. Movement that separates the first fixed unit 21 and the communication device 131 without changing the positional relationship between the fixed unit 21 and the communication device 131 is limited.

  With such a configuration, it is possible to prevent the polarization processor 161 from easily falling off the communication device 131.

  In the polarization processor according to the second embodiment of the present invention, the communication device 131 includes communication device connectors 43v and 43h. The guide portion 93g is hollow. The communication-device-side connectors 43v and 43h are located on the inner space 93s side of the guide 93g with respect to the opening surface 93ga of the guide 93g on the reflection unit 1 side.

  With such a configuration, the protruding portions of the communication device connectors 43v and 43h with respect to the communication device 131 can be accommodated in the internal space 93s of the guide portion 93g, so that the communication device connectors 43v and 43h come into contact with other components. This can reduce the possibility of damage.

  Other configurations and operations are the same as those of the antenna device according to the first embodiment, and thus detailed description will not be repeated here.

  In addition, some or all of the components according to the first embodiment and the second embodiment of the present invention can be appropriately combined.
