2 to 9, an antenna apparatus according to embodiments of the present invention may include a support body 100 and a plurality of antennas 200 mounted on the support body 100.

1. Support

The support 100 may be installed in a vessel, a communication terminal on the ground, or a communication station, and a plurality of antennas 200 may be installed on the support 100. That is, a plurality of antennas 200 may be mounted on the support 100, and the support 100 on which the plurality of antennas 200 are mounted may be installed in a vessel, or installed in a communication terminal or a communication station on the ground.

The support 100 may have a predetermined length L in the horizontal direction X and a predetermined height H in the vertical direction Y. [ At this time, the length L of the lower surface and the height H to the upper surface may be formed in a ratio of 2: 1 to 1:10. That is, the length L of the lower surface of the support body 100 may be greater than, equal to, or less than the height H. For example, the support 100 may be formed such that the height H is 1.5 to 10 times larger than the length L of the lower surface. As a specific example, the length L of the lower surface of the support 100 may be 1 m to 15 m, and the height H may be 2 m to 20 m. More specifically, the support 100 may have a length L of the lower surface of 5 m to 11 m and a height H of 8 m to 15 m. The ratio of the length L to the height H of the lower surface of the support 100 depends on the structure such as a trap to which the antenna device is mounted, the number and size of the antenna 200, the frequency band of the antenna 200, And can be variously modified. However, considering the number of antennas 200 mounted on the support 100, the vertical and horizontal spacing according to the frequency band of the antenna 200, and the like, the height H of the supporter 100 is set to the length L ) Is preferably at least two times larger than that of the first embodiment.

In addition, the support 100 may have a length and a width gradually reduced from a lower portion to a predetermined region at an upper portion, and may be formed to have the same length and width from the predetermined region to the uppermost portion. That is, the support 100 may have a length and a width reduced from a lower surface to a first height H1 at a predetermined angle, and may be formed vertically from a first height H2 to a second height H2. In other words, the support 100 may include a first region having a predetermined slope at a side in the height direction Y and a second region perpendicular to the first region, the first region having a first height H1, The area is from the first height H1 to the top. Of course, the second height H2 may be formed to have a predetermined slope without being formed vertically. That is, the support 100 may have a predetermined slope from the bottom to the top so that a predetermined horizontal surface is formed at the top. On the other hand, when the second height H2 has a predetermined slope, the angle of the second height H2 may be equal to or different from the angle of the first height H1. The area of the second height H2 portion, that is, the side surface shape of the second region may be the same as or different from the area of the first height H1 portion, that is, the side surface of the first region. The support 100 may be formed to have a predetermined inclination without being formed vertically at least to the first height H1 so that a trap or the like equipped with the antenna device can have a stealth function. When the side surface of the support body 100 is vertically formed, a radio wave such as a radar emitted from the enemy is reflected and transmitted to the enemy, so that the enemy can be detected. However, by forming the side surface of the support body 100 in an oblique shape, The emitted radio waves can be reflected in other directions than the enemy, so that the enemy may not be detected by the enemy. That is, the support 100 may have a stealth function by forming the side surface of the support 100 in a slanting shape having a predetermined slope. On the other hand, the first height H1 may have an angle of less than 90 degrees. That is, the first area up to the first height H1 may have an acute angle formed by the lower surface and the side surface. For example, the first region up to the first height H1 may have an angle of between 45 degrees and less than 90 degrees, preferably between 60 and 80 degrees. That is, the imaginary line perpendicular to the end of the lower surface of the support 100 and the side surface of the support 100 may have an angle of 10 ° to 20 °. However, the angle of the first height H1 formed between the lower surface and the side surface may be variously changed according to the structure of a trap or the like on which the antenna device is mounted, the number and size of the antenna 200, the frequency band of the antenna 200, have. Meanwhile, the support body 100 may have a ratio of the first height H1 and the second height H2 of 1: 1 to 10: 1. That is, the first height H1 may be greater than or equal to the second height H2. The ratio of the first height H1 to the second height H2 may vary depending on the structure of a trap to which the antenna device is mounted, the number and size of the antenna 200, the frequency band of the antenna 200, and the like . For example, the first height H1 and the second height H2 may have a ratio of 3: 1 to 5: 1.

In addition, the support 100 may have an octagonal planar shape as shown in Figs. 3 and 5, and may have a substantially rectangular planar shape as shown in Figs. 3 and 4 may be a plan view of the lower surface of the support 100 on which the antenna 200 is not mounted and a plan view in which a predetermined region up to the first height H1 is cut. That is, the support 100 may have the same shape from the lower surface to the first height H1. 5 and 6 are plan views of a predetermined region up to the first height H1 of the support 100 on which the antenna 200 is mounted. As shown in FIGS. 3 to 6, the support 100 may be provided with a hollow space therein, and the entire circumferential shape may be an octagon or a substantially rectangular shape. Of course, the support 100 may have an interior filled with an octagonal shape or a substantially rectangular shape. In this case, the peripheral shape is octagonal, which means that the lengths of the eight surfaces are the same and the angles between the surfaces are the same as shown in Figs. 3 and 5. The term " substantially rectangular " means that the lengths of the four surfaces are the same as shown in FIGS. 4 and 6, and the corner where the two sides of the rectangle meet is chamfered to form a predetermined plane. That is, the substantially quadrangular shape refers to that the inner shape of the support body 100 is a quadrangle, and the outer shape is an octagonal shape in which a corner portion is chamfered to form a plane smaller than four sides.

The support 100 may be made of an insulator or a conductor, and may be made of a composite of an insulator and a conductor. That is, the side surface of the support 100 may be composed of an insulator, a conductor, and a composite of an insulator and a conductor. Here, the insulator used as the support 100 may include a thermoset resin such as an epoxy or a thermoplastic. In addition, the insulator used for the support 100 may comprise a fiber reinforced polymer. The fiber reinforced polymer may comprise a sheet of reinforcing fiber material bonded to the polymer matrix material. The polymer may comprise a thermosetting resin or a thermoplastic resin and the fiber material may comprise a woven or nonwoven to continuously reinforce fibers or filaments. On the other hand, the support 100 may be formed of a single layer using an insulator, or may be formed of a multilayer structure of at least two layers or more. When a multilayer structure is formed, an insulator such as a fiber reinforced polymer may be formed on both sides of the core of the honeycomb structure. For example, a fiber reinforced polymer may be attached to both sides of a urethane foam having a plurality of pores to form a multi-layered support 100. On the other hand, the support 100 may be made of a conductor such as a metal or a mixture of a metal and an insulator. Of course, the support 100 may have a metal-coated form on the inner or outer surface of the insulator.

For example, the plurality of antennas 200 may include a radar antenna 210, a very high frequency (VHF) antenna 220, a UHF (Ultra High Frequency) antenna 230, a TACAN (Tactical Air Navigation) (VHF / UHF) antenna 250, an identification of friend or foe (IFF) antenna 260, and a Global Positioning System (GPS) antenna 270. That is, the plurality of antennas 200 may include a radar antenna, a communication antenna (VHF, UHF, TACAN, GPS antenna), and an IFF antenna. The VHF antenna 220 transmits and receives frequency signals of 30 MHz to 300 MHz and the UHF antenna 230 and the TACAN antenna 250 transmit and receive radar signals of X- And the IFF antenna 260 and the GPS antenna 270 transmit and receive a frequency signal of 1 GHz band. That is, the TACAN antenna 250 transmits and receives a frequency signal within the frequency range of the UHF antenna 230.

The plurality of antennas 200 may be spaced apart from the support 100 by a predetermined distance to suppress mutual interference. The antenna 200 may be installed in a plurality of regions of the support 100 according to the size of the antenna 200. For example, the radar antenna 210 having the largest size is provided on the lower side of the support 100 and includes a VHF antenna 220, a UHF antenna 230, a TACAN antenna 240, and a VHF / UHF dual antenna 250 may be provided on the upper side of the radar antenna 210. A VHF antenna 220, a UHF antenna 230, a TACAN antenna 240, and a transceiver antenna 240 are provided on a radar antenna 210 in a predetermined area of the first height H1 of the support body 100, And a VHF / UHF combined antenna 250 may be provided. At this time, as shown in FIG. 3, the radar antenna 210 may be formed on at least four sides when the side of the support 100 is octagonal. That is, four radar antennas 210 may be installed on the side of the support 100, respectively, across one surface. Of course, when the side of the support 100 is octagonal, the radar antenna 210 may be installed on eight surfaces. As shown in FIG. 4, the radar antenna 210 may be installed on four sides when the side of the support 100 is rectangular.

In addition, the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 may be provided on the upper side of the radar antenna 210. The UHF antenna 230 and the TACAN antenna 240 have the same size or the TACAN antenna 240 has the same size as the UHF antenna 230 and the TACAN antenna 240. The VHF antenna 220 is larger than the UHF antenna 230 and the TACAN antenna 240, . In addition, two VHF antennas 220, two UHF antennas 230, and one TACAN antenna 240 may be provided on the same surface at a predetermined interval. For example, the UHF antenna 230, the VHF antenna 220, the TACAN antenna 240, the VHF antenna 220, and the UHF antenna 230 may be provided in this order as shown in FIGS. 5 and 6 . That is, a UHF antenna 230 and a TACAN antenna 240 may be provided with a VHF antenna 220 interposed therebetween. The VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 may be formed on four sides when the support 100 has an octagonal shape as shown in FIG. 5, Similarly, when the support 100 has a rectangular shape, it may be formed on four sides. 7 to 9, a VHF antenna 220, a UHF antenna 230, and a TACAN antenna 240 may be provided on one side of the support 100, respectively, as shown in FIGS. have. At this time, the UHF antenna 230 and the TACAN antenna 240 may be provided on one side and the other side of the VHF antenna 230, respectively. The VHF / UHF combined antenna 250 may be provided on another plane of the same height as the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240. The VHF / UHF combined antenna 250 may be configured such that the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 are formed when the support 100 has an octagonal shape as shown in FIGS. 5 and 8 And when the support 100 has a rectangular shape as shown in FIGS. 6 and 9, corner portions where two adjacent surfaces meet may be formed on the chamfered surface.

The IFF antenna 260 may be provided on the second height H2 region of the support 100, that is, on the side of the second region. The IFF antenna 260 may be installed in all directions, i.e., 360 degrees, and may be formed on the entire surface of the second height H2 region. 3, IFF antennas 260 may be provided on eight surfaces when the side surface of the supporting body 100 is octagonal, and as shown in FIG. 4, the side surface of the supporting body 100 is rectangular The IFF antenna 260 may be installed on four sides. However, the shape of the first height H1 region and the second height H2 region of the support 100 may be different. For example, even when the first height H1 region has a rectangular shape, the second region H2 may have an octagonal shape. Therefore, the IFF antenna 260 can be formed on eight surfaces of the second height H2 region having an octagonal side surface shape. Of course, both the first height H1 region and the second height H2 region may have an octagonal shape. In addition, the first height H1 region may be provided in a rectangular shape with chamfered edges, and the second height H2 region may be provided in a rectangular shape in which chamfers are not chamfered. Meanwhile, a GPS antenna 270 may be provided on the upper surface of the support body 100, that is, the upper surface of the second area H2. The GPS antenna 270 may be formed on the top surface of the support 100 in communication with the satellite.

The plurality of antennas 200 may each have a predetermined shape and a predetermined size. First, each of the plurality of antennas 200 may be provided with a rectangle having a predetermined length and a predetermined length. Of course, each of the plurality of antennas 200 may be provided in a circular shape having a predetermined diameter. In addition, the plurality of antennas 200 may be provided at least partially in a quadrangular shape and at least partially in a circular shape. At this time, as mentioned above, the radar antenna 210, the IFF antenna 270, the VHF antenna 220, and the UHF / TACAN antennas 230 and 240 may be sized in order. That is, the radar antenna 210 has the largest area, and the UFH antenna 230 and the TACAN antenna 240 can have the largest area. Although the VHF / UHF combined antenna 250 and the GPS antenna 270 are not provided on the same side, they do not show a relative size. However, they do not have a size between the radar antenna 210 and the UHF / TACAN antennas 230 and 240 Lt; / RTI > The plurality of antennas 200 may be spaced apart from each other by a predetermined distance in the vertical and horizontal directions in order to suppress mutual interference. A VHF antenna 220, a UHF antenna 230, and a TACAN antenna 240 are provided in a second region on the lowermost side of the same side of the support body 100 And an IFF antenna 270 may be provided in a third region on the upper side thereof. That is, the plurality of antennas 200 can maintain a predetermined distance in the vertical direction on the same side of the support 100. At this time, the distance between the radar antenna 210 and the upper VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 may be equal to or shorter than the vertical length of the VHF antenna 220. That is, when the vertical length of the VHF antenna 220, that is, the height is A and the distance from the radar antenna 210 to the adjacent end line of the VHF antenna 220 is B, A? For example, if the VHF antenna 220 has a length of 0.5 m to 1 m and a length of 0.8 m to 1.5 m, and a distance between the radar antenna 210 and the VHF antenna 220 is 0.1 m to 1.2 m . That is, the distance between the radar antenna 210 and the VHF antenna 220 may be 0.5 to 1 times the vertical length of the VHF antenna 220. If the distance between the radar antenna 210 and the VHF antenna 220 is within the above range, interference between the antennas may occur. If the distance exceeds the above range, the distance from the interference effect may be too far away to increase the height . The distance from the upper surface of the VHF antenna 220 to the lower surface of the IFF antenna 260 may be equal to or greater than the vertical length of the VHF antenna 220. That is, when the vertical length of the VHF antenna 220, that is, the height is A, and the distance from the upper end of the VHF antenna 220 to the lower end of the IFF antenna 260 is C, A? For example, the VHF antenna 220 may have a length of 0.5 m to 1 m and a length of 0.8 m to 1.5 m, and the distance between the VHF antenna 220 and the IFF antenna 260 may be 1 m to 6 m . That is, the distance between the VHF antenna 220 and the IFF antenna 260 may be 1 to 10 times the vertical length of the VHF antenna 220. If the distance between the VHF antenna 220 and the IFF antenna 260 is within the above range, interference between the antennas may occur. If the distance exceeds the above range, the distance between the VHF antenna 220 and the IFF antenna 260 may deviate from the influence of interference, . Meanwhile, the UHF antenna 230 may have the same size as the TACAN antenna 240 or may have different sizes. For example, the transverse length of the UHF antenna 230 may be greater than or equal to the transverse length of the TACAN antenna 240, and the transverse length of the UHF antenna 230 may be less than or equal to the transverse length of the TACAN antenna 240 . For example, the UHF antenna 230 has a length of 0.4 to 0.5 m and a length of 0.6 to 0.8 m, and the TACAN antenna 240 has a length of 0.1 to 0.2 m and a length of 0.7 to 0.9 m, Lt; / RTI > In addition, the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240, which are adjacent to each other in the horizontal direction, can also maintain a predetermined gap. At this time, the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 may maintain the same interval, and the interval therebetween may be shorter or longer than the transverse length of the UHF antenna 230. For example, the spacing between the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 may be 1/3 to 2 times longer than the transverse length of the UHF antenna 230. Specifically, the interval between the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 may be 0.1 m to 1.2 m.

The plurality of antennas 200 may be installed on the surface of the support 100. Further, the plurality of antennas 200 may be provided in the grooves after the predetermined grooves are formed in the supporting body 100. That is, the antenna 200 may be provided such that a plurality of grooves are formed in a predetermined area of the support 100 and then at least partially inserted into the grooves. At this time, the grooves may be formed in a plurality of sizes depending on the size of the antenna 200. [ Of course, at least some of the antennas 200 may be installed on the surface of the support 100, and at least some of the antennas 200 may be embedded at least partially in the grooves formed in the support 100.

As described above, the embodiments of the present invention can be applied to a support (hereinafter, referred to as " support member ") in a shape having a predetermined inclination from a lower portion to a first height H1 at an upper side and a side surface perpendicularly from a first height H1 to a second height H2 100, and a plurality of antennas 200 may be installed on the side surface of the support body 100. The plurality of antennas 200 are spaced apart from each other by a predetermined distance according to the size and transmission / reception frequency of the individual antennas, thereby reducing interference between the antennas 200. That is, the radar antenna 210 having the largest size is provided on the lowermost side of the first area up to the first height H1 of the supporter 100, and the VHF antenna 220, the UHF An antenna 230, a TACAN antenna 240, and a VHF / UHF dual antenna 250 are provided in the horizontal direction. An IFF antenna (not shown) is provided in a second height (H2) region from the end to the top of the first region, A GPS antenna 270 may be provided on the horizontal plane of the top. The plurality of antennas 200 may be spaced apart from each other by a predetermined distance in accordance with the size and frequency band of the individual antennas, so that interference between the antennas 200 can be suppressed. In addition, since the supporting body 100 is formed to be inclined on the side surface, it is possible to make the weapon equipped with the antenna structure have a stealth function by reflecting the electromagnetic wave radiated from the enemy in a direction other than the enemy direction.

Meanwhile, a plurality of antennas of the antenna structure according to an embodiment of the present invention may have different shapes. That is, the VHF antenna 220, the UHF antenna 230, the TACAN antenna 240, and the VHF / UHF combined antenna 250 may have a cavity-backed antenna having a broadband, low- ≪ / RTI > That is, the cavity antenna structure may include a conductor having a predetermined cavity, that is, an empty space, and a radiator provided inside the cavity. At this time, a general radiator is provided at a central portion of the cavity, but the radiator of the cavity antenna according to the present invention may be biased to one side.

The radiator 320 is disposed on one side (for example, The upper side or the lower side). In other words, the radiator 320 may be offset from the center of the cavity toward the upper side or the lower side. 11 and 12 illustrate arrangements of the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 using the cavity antenna provided with the radiator moved to one side. 11 shows that the radiators 320a, 320b and 320c of the VHF antenna 220, the UHF antenna 230 and the TACAN antenna 240 are moved upward. 12 shows that the radiator 320a of the VHF antenna 220 moves upward and the radiators 320b and 320c of the UHF antenna 230 and the TACAN antenna 240 move downward. By providing the radiator 320 in one direction, it is possible to further secure the distance from the radiator 320 of the adjacent antenna, thereby further suppressing the interference between the adjacent antennas. 13 shows a radiation pattern of the cavity antenna in which the radiator is moved to one side. As can be seen from the radiation pattern of FIG. 13, it can be seen that the radiation pattern is maintained even though the emitter is moving. Meanwhile, the radiator 320 may be provided in a microstrip dipole shape as shown in FIG.

15 is a schematic view showing an arrangement shape of the IFF antenna 260. Fig. The IFF antenna 260 must transmit the signal in 360 占 o frontward direction and receive the signal from all directions. Accordingly, the IFF antenna 260 may be provided on the entire side of the second height H2 region of the support 100. [ At this time, the IFF antenna 260 may be installed in a square, octagonal or circular shape as shown in FIG. 15 according to the shape of the second height H2 region. That is, the IFF antenna 260 may be arranged in the shape of a square, an octagon, a circle, or the like on the entire circumference of the second height H2 region using a microstrip dipole or a cavity antenna.

16 is a schematic view showing an outer shape of the arrangement of the GPS antenna 270. Fig. The GPS antenna 270 is provided at the top of the support 100 and may be provided with a single antenna or an array antenna capable of beam forming. At this time, the GPS antenna 270 may be arranged to have a circular or rectangular outer shape.

As described above, the VHF antenna 220, the UHF antenna 230, and the TACAN antenna 240 are separately provided on the side surface of the support body 100 so that the interference between the antennas is suppressed, An IFF antenna 260 may be provided on the side of the antenna for suppressing mutual interference between VHF, UHF, TACAN, and IFF antennas. The GPS antenna 270 is an antenna for collecting satellite signals and is installed on the top of the support 100. The GPS antenna 270 is structurally separated from the VHF, UHF, TACAN, and IFF antennas, Minimizing mutual interference. On the other hand, VHF, UHF, and TACAN antennas can be installed redundantly considering the survival performance of the equipment. VHF / UHF antennas can also be installed separately in the structure. In this case, the mutual interference can be minimized by installing VHF, UHF, IFF, TACAN and GPS antennas. VHF, UHF, TACAN, IFF, and GPS antennas can be installed at the bottom of the structure.
