Example (b):
referring to fig. 1 to 4, the high temperature resistant miniaturized dual-ridged horn antenna in the preferred embodiment of the present invention includes an antenna adapter 1, a dual ridged body 50 disposed on the antenna adapter 1, and an antenna reflection cavity 2 disposed around the dual ridged body 50.
Specifically, the antenna adapter 1 in the preferred embodiment is a special-shaped structure, and one end of the antenna adapter is a first mounting end for mounting the double-ridge body 50 and the antenna reflection cavity 2; the other end is a second mounting end for mounting the sockets at the tail ends of the first cable 3 and the second cable 4. In actual installation, one end of the first installation end, which is used for installing the double-ridge body 50, is a cylindrical structure, and the end surface of the first installation end, which is used for connecting the second installation end, is a wedge-shaped surface which forms a certain angle with the cross section of the cylindrical structure, which is obtained by cutting the cylindrical structure in a direction which forms a certain inclination angle with the radial direction, and the obtained wedge-shaped surface is often used as an installation surface of the antenna adapter 1 in the cabin section. By means of the arrangement, a certain angle is formed between the mounting surface of the antenna adapter 1 and the axis of the antenna adapter, so that the antenna can be tilted downwards by a certain angle to transmit and receive signals when in work, and the frequency range of the antenna is effectively enlarged.
Correspondingly, one end of the second mounting end is correspondingly connected to the wedge-shaped surface of the first mounting end, so that a certain included angle is formed between the axis of the second mounting end and the axis of the first mounting end. In a preferred embodiment, the angle between the two axes is 10 ° to 30 °, and more preferably 20 °. Furthermore, the second mounting end is preferably connected at a position of the wedge-shaped surface facing away from the center.
Further, the double-ridged body 50 in the preferred embodiment is mounted on the end surface of the first mounting end facing away from the second mounting end, and includes an antenna base 501 and two orthogonally disposed antenna ridge units, which include two antenna ridges disposed in the same plane.
As shown in fig. 2, the antenna base 501 in the preferred embodiment is a cylindrical structure, and a conical inner cavity is formed in the middle of the antenna base 501, and the inner diameter of the conical inner cavity on one side close to the antenna base 501 is larger than that on the other side, which is beneficial for the reflection and emission of four antenna ridge signals. Meanwhile, four square grooves are formed in the inner circumferential ring of the inner cavity structure at intervals and used for mounting four antenna ridges.
Specifically, the four square grooves in the preferred embodiment are spaced by 90 °, so that the two antenna ridge units are orthogonally arranged, and the emission and the transmission of signals of the double-ridge body 50 are facilitated. Preferably, one end of the square groove is communicated with the top of the antenna base 501, and the other end is not communicated with the bottom of the antenna base 501, which is equivalent to that a limiting table is formed at the bottom of the square groove, and each limiting table is located in the same plane, so that it is ensured that the four antenna ridges can be installed on the same plane. In addition, a plurality of lugs are arranged on the periphery of the bottom of the antenna base 501 at intervals, and through holes penetrating through two end faces of the lugs are formed in the lugs and used for installing the antenna base 501 on the antenna adapter 1 after a connecting piece penetrates through the through holes.
Further, the end surface of the antenna adapter 1 in the preferred embodiment is provided with a special-shaped groove corresponding to the antenna base 501, for correspondingly embedding the end of the antenna base 501 with the arc-shaped support lug. Correspondingly, the bottom of the special-shaped groove is provided with a fastening hole corresponding to the through hole on the arc-shaped support lug, and a connecting piece (such as a screw) is connected in the fastening hole after penetrating through the through hole, so that the antenna base 501 is installed on the end face of the antenna adapter 1.
Further, as shown in fig. 2 to 4, a first antenna ridge unit is composed of a first antenna ridge 502 and a third antenna ridge 504 which are located in the same plane, a second antenna ridge unit is composed of a second antenna ridge 503 and a fourth antenna ridge 505 which are located in the other plane, and the two antenna ridge units are orthogonally installed on the antenna base 501, which is equivalent to that the four antenna ridges are respectively arranged at intervals of 90 °. In practice, the two antenna ridge units are preferably identical in structure.
Taking the first antenna ridge unit as an example for description, as shown in fig. 3 and 4, the two antenna ridges (502, 504) are respectively of a plate-shaped structure, the two plate bodies respectively have a certain curved arc surface, and the double-ridge curves of the two plate bodies in the antenna ridge unit are symmetrically arranged. Meanwhile, the bottoms of the side surfaces of the two antenna ridges, which are deviated from each other, are provided with at least one fastening hole; correspondingly, a through hole penetrating through the side wall surface of the square groove is formed in the outer peripheral wall surface of the antenna base 501, and a connecting piece penetrates through and is connected to the fastening hole in the bottom of the side surface of the antenna ridge embedded into the square groove at the bottom, so that the antenna ridge is installed in the antenna base 501. In practice, the number of fastening holes is not less than two, for example, two as shown in fig. 2.
Furthermore, a pressing plate groove is formed in the bottom end face of one of the antenna ridges in the same antenna ridge unit and used for installation of the pressing plate 506. In the preferred embodiment as shown in fig. 3, the platen slot is open at the bottom of the third antenna ridge 504; obviously, the above-mentioned pressing plate groove may be disposed at the bottom of the first antenna ridge 502 correspondingly when actually disposed. By the arrangement of the pressing plate 506, the installation of the corresponding cable can be realized.
Specifically, in the pressure plate groove in the preferred embodiment, a semicircular curved groove is formed, one end of which penetrates through the third antenna ridge 504 and faces the side wall surface of the first antenna ridge 502, and the other end of which penetrates through the bottom of the third antenna ridge 504, as shown in fig. 4, so that the cable can extend from the bottom of the third antenna ridge 504 to the side wall surface of the third antenna ridge 504 and faces the first antenna ridge 502. Meanwhile, a semicircular curve groove corresponding to the semicircular curve groove on the pressure plate groove is formed on the end face, close to the pressure plate groove, of the pressure plate 506, so that when the pressure plate 506 is installed in the pressure plate groove, a through groove with a circular cross section can be formed for clamping the cable. Therefore, the stable arrangement of the cable can be ensured, and the cable can be prevented from being damaged due to overlarge extrusion force. Preferably, the mounting of the pressure plate 506 in the pressure plate slot is realized by a plurality of countersunk screws, and the screw head end surfaces of the countersunk screws preferably do not protrude from the end surface of the third antenna ridge 504, so as to prevent the protrusion of the screw head from causing interference to the antenna signal parameters.
Further, a blind hole with a certain depth is formed in the side wall surface of the first antenna ridge 502, which is opposite to the end part of the semicircular curved groove, and is used for the extension of the inner conductor of the cable; in addition, a bottom hole penetrating through the blind hole is opened at the bottom of the first antenna ridge 502 for screwing in of the set screw 507, thereby achieving compression of the end of the inner conductor of the cable, as shown in fig. 4. Through the arrangement, the cable can be stably arranged and reliably contacted in the antenna ridge unit, and the reliability of communication is ensured.
In the preferred embodiment, set screw 507 inserted into the bottom hole is a slotted flat end set screw and such that set screw 507 engages the end surface where the end is located without protruding through the bottom hole. Furthermore, in the preferred embodiment, a high temperature resistant cable, i.e. a first cable 3 and a second cable 4, the former preferably being a short cable and the latter preferably being a long cable, is provided for each antenna ridge element. Correspondingly, two socket mounting planes are arranged at the second mounting end of the antenna adapter 1 at intervals and used for mounting two cable tail end sockets. Meanwhile, cable installation grooves or cable installation through holes extending to the antenna base 501 are respectively provided corresponding to the two socket installation planes, for embedded installation of the first cable 3 and the second cable 4.
Further, as shown in fig. 1, the antenna reflection cavity 2 in the preferred embodiment is a thin-walled cylindrical structure, which is sleeved outside the double-ridge body 50 and is sleeved at the end part of the antenna adapter 1. Correspondingly, an annular groove is further formed in the periphery of the end portion of the antenna adapter 1 along the annular direction, and an annular step structure is formed at the end portion of the first mounting end and used for sleeving the end portion of the antenna reflection cavity 2. Meanwhile, a plurality of fastening holes are formed in the circumferential wall surface of the annular stepped structure at intervals in the circumferential direction corresponding to the antenna reflection cavity 2, through holes penetrating through the inner wall surface and the outer wall surface are formed in the outer circumference of the end portion of the antenna reflection cavity 2 capable of being sleeved with the antenna base 501 at intervals in the circumferential direction, and the through holes are aligned with the corresponding fastening holes, so that a connecting piece (such as a countersunk screw) can penetrate through the through holes and be connected into the fastening holes, and the antenna reflection cavity 2 is mounted on the antenna base 501.
Preferably, the outer diameter of the antenna reflection cavity 2 is equal to the outer diameter of the first mounting end of the antenna adapter 1, so that after the antenna reflection cavity 2 is sleeved on the periphery of the first mounting end, the peripheral wall surface of the antenna reflection cavity 2 can be flush with the peripheral wall surface of the first mounting end. Meanwhile, after the antenna reflection cavity 2 and the double-ridged body 50 are simultaneously mounted on the antenna adapter 1, the end of the antenna reflection cavity 2 preferably does not protrude from the top of the double-ridged body 50 (in practice, it is often slightly lower than the top boundary of the double-ridged body 50). In addition, four signal grooves are circumferentially arranged at intervals at the end of the antenna reflection cavity 2 away from the antenna base 501, so as to be beneficial to the emission and outward transmission of signals of the double-ridge body 50, as shown in fig. 1; and the square groove is preferably arranged on a central line of an included angle formed by planes of the two antenna ridge units, namely the angle interval between the position of the central line of each square groove and the central line of the adjacent two antenna ridges is 45 degrees respectively.
Furthermore, the ambient temperature of the double-ridge horn antenna is often higher than 300 ℃, and the deformation of the antenna reflection cavity 2 after being heated has a great influence on the antenna index parameters. In view of this, in the preferred embodiment, the antenna reflection cavity 2 is preferably made of a titanium alloy material. The reason is that after investigation and structural simulation calculation, the expansion coefficient of the heated titanium alloy is far smaller than that of the common aluminum alloy, the structural strength is larger than that of the aluminum alloy, and even in a 480 ℃ extremely high temperature environment, the deformation of the cavity is still small, so that the influence of the excessive deformation of the cavity caused by high temperature on the index parameters of the antenna can be effectively reduced. Moreover, along with the continuous rising of operational environment temperature, antenna reflection cavity 2 can play the effect of heat exchanger that separates, avoids the 50 high temperatures of two spine bodies effectively, guarantees two spine horn antenna's job stabilization nature.
It is further preferred that at least one lug, for example two lugs shown in fig. 1, is provided on the end surface of the first mounting end connected to the second mounting end for mounting the antenna adapter 1 to the cabin segment. Meanwhile, in order to reduce the self weight of the double-ridged horn antenna, the antenna adapter 1 in the preferred embodiment is preferably made of a light aluminum alloy material, and a part of the area is preferably provided with a hollow structure, so that the mass of the antenna adapter 1 is further reduced.
The high-temperature-resistant miniaturized double-ridge horn antenna is simple in structure and convenient to assemble, the size of the double-ridge horn antenna can be effectively reduced through the corresponding design of structural components, the double-ridge horn antenna can be installed in a cabin section with a narrow space, the antenna design on different types of projectiles is met, and the technical development of the small projectiles is promoted; meanwhile, through the design of related structures and the optimization of related materials, the communication quality of the antenna can be further improved, the self weight of the antenna is reduced, the functionality of the antenna on the projectile body is further improved, the technical development of various flight devices is promoted, and the projectile body has a better application prospect and a higher popularization value.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
