[0066] Referring to Figures 1 to 6 , the radar module assembly 100 according to a first embodiment of the present invention may include: a housing 120, an antenna module 130, a substrate 140, a substrate support frame 150, and a radome 110.

[0067] Referring to Figure 1 and Figure 2 , the antenna module 130, the substrate 140, and the substrate support frame 150 of the radar module assembly 100 according to a first embodiment of the present invention are fastened and assembled by a fastening member 170 such as a screw, and thus modularization can be achieved.

[0068] The antenna module 130, the substrate 140, and the substrate support frame 150 assembled and modularized as described above may be named an antenna module assembly. The modularized antenna module 130, the substrate 140, and the substrate support frame 150 may be formed to be built in the radome 110 and the housing 120 that form the outer shape of the radar module assembly 100.

[0069] In an embodiment of the present invention, for example, the housing 120 may be configured in a hexahedron shape and may be formed of a synthetic resin material such as plastic.

[0070] Refer to Figure 2 , the housing 120 includes: a bottom surface portion 122, which is in the shape of a quadrilateral plate forming the bottom surface of the housing 120; a side wall portion 124, when observed from Figure 2 , extends in the z-axis, i.e., the upward direction, from the four corner portions of the bottom surface portion 122 to form four side walls.

[0071] At the upper end of the side wall portion 124, a radome coupling portion 125 is formed to protrude upward and can be coupled to the side coupling portion 114 of the radome 110. The radome coupling portion 125 can be continuously formed to protrude along the upper perimeter of the housing side wall portion 124, so as to form a watertight structure inside the housing 120.

[0072] A first internal space 123 is formed inside the housing 120, in which the antenna module 130, the substrate 140, and the substrate support frame 150 can be placed.

[0073] In order to fix the positions of the antenna module 130, the substrate 140, and the substrate support frame 150 without shaking in the state where they are placed in the first internal space 123, one or more position fixing protrusions 127 are formed on the inner surface of the side wall portion 124 inside the housing 120.

[0074] When observed from Figure 2 , the position fixing protrusion 127 is configured as a strip extending in the z-axis direction and protrudes from the inner side of the housing towards the inside of the housing 120.

[0075] Corresponding to the formation positions of the position fixing protrusions 127, position fixing grooves 137, 147, and 157 are formed on the sides of the antenna module 130, the substrate 140, and the substrate support frame 150.

[0076] Accordingly, in the state where the antenna module 130, the substrate 140, and the substrate support frame 150 are placed in the first internal space 123 of the housing 120, the position fixing grooves 137, 147, and 157 are in contact with the position fixing protrusions 127 to perform position fixing, and the antenna module 130, the substrate 140, and the substrate support frame 150 can be stably fixed in the first internal space 123.

[0077] A terminal portion 129 is disposed on one side of the first internal space 123 of the housing 120.

[0078] As Figure 2 shown, the terminal portion 129 includes a plurality of pin members, and the plurality of pin members are formed such that one end portion faces upward from one end side in the x-axis direction of the first internal space 123 of the housing 120.

[0079] As Figure 5As shown, the other end portions of the plurality of needle members are formed to protrude by extending outward through the external terminal connection portion 128.

[0080] According to an embodiment of the present invention, when the antenna module 130, the substrate 140, and the substrate support frame 150 are placed in the first internal space 123 of the housing 120, the terminal coupling holes 148 of the substrate 140 can be coupled to the terminal portion 129. Accordingly, the substrate 140 can be electrically connected to an external device of the housing 120 through the external terminal connection portion 128.

[0081] Fastening member coupling grooves 126a are formed at four corner portions of the first internal space 123 of the housing 120. Furthermore, the fastening members 170 for coupling the antenna module 130, the substrate 140, and the substrate support frame 150 can be stably coupled inside the first internal space 123 of the housing 120.

[0082] At this time, according to an embodiment of the present invention, one or more fastening member coupling protrusions 126b protrude from the bottom surface 122 of the housing 120.

[0083] In an embodiment of the present invention, the fastening member 170 penetrates through four corner portions of the antenna module 130, the substrate 140, and the substrate support frame 150 for coupling, and then can be coupled to the fastening member coupling grooves 126a formed at four corner portions inside the first internal space 123 of the housing 120.

[0084] Then, on this basis, after penetrating through the interiors of the antenna module 130, the substrate 140, and the substrate support frame 150, the penetrated fastening member 170 can be coupled to one or more fastening member coupling protrusions 126b protruding from the bottom surface 122 of the housing 120.

[0085] At this time, the fastening member coupling grooves 126a formed at four corner portions are holes into which the fastening member 170 can be inserted, formed at a predetermined height spaced upward from the bottom surface 122 of the housing 120. Along the fastening member coupling grooves 126a, a boss portion 121 of a predetermined height is formed on the inner surface of the side wall portion 124 of the housing 120.

[0086] The boss portion 121 supports a border portion 156 formed along the outer perimeter of the substrate support frame 150 in a state where the substrate support frame 150 is coupled to the first internal space 123 of the housing 120. Accordingly, the substrate support frame 150 can be stably supported inside the first internal space 123 of the housing 120 without shaking.

[0087] In addition, the outer side surface of the substrate support frame 150 has a quadrilateral cross-section and can be configured to have a shape corresponding to the inner surface of the side wall portion 124 of the first internal space 123 of the housing 120.

[0088] Accordingly, in a state where the substrate support frame 150 is inserted and fixed inside the first internal space 123 of the housing 120, the outer side surface of the substrate support frame 150 is configured to be adjacent to the inner side surface of the side wall portion 124 of the first internal space 123 of the housing 120. Accordingly, a radar module assembly 100 with a compact structure can be provided.

[0089] On the other hand, in the present embodiment, one or more fastening member coupling protrusions 126b protruding from the bottom surface portion 122 of the housing 120 are located on both side portions of the antenna chip 160 with the antenna chip 160 as the center. Accordingly, in a state where the antenna module 130, the substrate 140, and the substrate support frame 150 are coupled inside the housing 120, the antenna chip 160 can be firmly coupled to the substrate 140 and the antenna module 130, and thus radar signals can be stably transmitted and received.

[0090] Referring to Figure 2 and Figure 5 , the radome 110 is a cover covering the antenna module 130 and can be formed of an electrical insulator material.

[0091] In an embodiment of the present invention, when viewed from Figure 2 , the radome 110 has an upper plate portion 112 with a quadrilateral shape on the upper surface facing the z-axis direction, and is arranged in front of the antenna module 130 located inside the radar module assembly 100.

[0092] Side coupling portions 114 are formed at four corners of the upper plate portion 112, and the side coupling portions 114 are formed such that grooves for accommodating the radome coupling portion 125 of the housing 120 open downward.

[0093] The radome 110 can be designed in terms of material, size, shape, etc. to stably transmit and receive signals with the outside through the antenna module 130.

[0094] Referring to Figure 3 and Figure 4 , in an embodiment of the present invention, the antenna module 130, the substrate 140, and the substrate support frame 150 are coupled inside the first internal space 123 of the housing 120 in a stacked manner.

[0095] The antenna module 130, the substrate 140, and the substrate support frame 150 are coupled inside the first internal space 123 of the housing 120 in a state of being integrated by the fastening member 170, or the antenna module 130, the substrate 140, and the substrate support frame 150 and the housing 120 can also be coupled simultaneously by the fastening member 170.

[0096] Referring to Figures 3 to 6, the antenna module 130 according to an embodiment of the present invention may include an antenna module body 131 having a quadrilateral plate shape structure. At this time, the antenna module body 131 may be formed of a synthetic resin material such as plastic, but the material of the antenna module body 131 is not limited thereto. At this time, a gold plating layer may be formed on the outer surface of the antenna module body 131.

[0097] In an embodiment of the present invention, when viewed from Figure 3 , a plurality of antenna slots 138 are formed on the upper surface of the antenna module 130.

[0098] Referring to Figure 6 , the plurality of antenna slots 138 are connected to a waveguide 135 inside the antenna module 130, and then connected to a waveguide connection hole 134 formed on the lower surface of the antenna module 130.

[0099] In an embodiment of the present invention, 8 antenna slots 138 may be formed. Among the 8 antenna slots 138, 4 are used for transmission, and the remaining 4 may be used for reception. At this time, the shape, number, and position of the antenna slots may vary according to the antenna design.

[0100] Referring to Figure 4 , a receiving groove 132 is formed on the lower surface of the antenna module 130, that is, the surface adjacent to the substrate. In order to avoid interference with a plurality of electronic components disposed on the substrate 140, the receiving groove 132 may have various depths and shapes on the lower surface of the antenna module 130.

[0101] The antenna module 130 according to an embodiment of the present invention is such that a receiving groove 132 for avoiding interference with electronic components mounted on the substrate 140 is formed on the surface adjacent to the substrate 140, and thus the total thickness of the antenna module 130 can be reduced, and accordingly, a compact-sized antenna module can be manufactured.

[0102] In an embodiment of the present invention, considering the height of the components mounted on the substrate 140, various designs can be made for the size, position, and shape of the receiving groove 132. In order to reflect this design, the antenna module 130 may be configured by laminating a plurality of plastic sheet components. However, the manufacturing method of the antenna module 130 is not limited thereto. For example, the antenna module may also be manufactured by means such as 3D printing. In addition, the antenna module 130 may be manufactured by various known methods.

[0103] On the other hand, referring to Figure 3 , Figure 4 and Figure 6, the antenna slot 138, the waveguide 135, and the waveguide connection hole 134 are connected to the feed hole 145 of the substrate. At this time, a gold plating layer is formed inside the antenna slot 138, the waveguide 135, and the waveguide connection hole 134 with metal, so that when the signal passing through the waveguide is transmitted to the outside through the antenna slot 138 from the feed hole 145 or received from the outside, the signal can be smoothly transmitted and received.

[0104] Referring to Figure 3 and Figure 4 , fastening holes 133 are formed through the four corners of the antenna module 130 and the vicinity of the center where the antenna chip 160 is located in the vertical direction, and fastening members 170 can be coupled.

[0105] Then, when observed from Figure 3 , a terminal anti-interference groove 139 is formed on the outer side of the antenna module 130 in the x-axis direction to prevent interference in the state where the terminal portion 129 of the substrate is coupled.

[0106] On the other hand, when observed from Figure 3 , position fixing grooves 137 are formed facing each other on both sides in the y-axis direction.

[0107] On the other hand, in an embodiment of the present invention, referring to Figure 3 and Figure 4 , the substrate 140 coupled to the lower portion of the antenna module 130 may be a PCB substrate formed of FR4 material. In an embodiment of the present invention, since the substrate 140 coupled to the lower portion of the antenna module 130 is formed of FR4 material, the manufacturing cost of the radar can be saved, and the radar module assembly 100 can have a simple structure.

[0108] On the other hand, according to an embodiment of the present invention, a plurality of feed holes 145 are formed in the center of the substrate 140. The plurality of feed holes 145 are channels for transmitting or receiving signals directly fed from the antenna chip 160. In this embodiment, eight feed holes 145 are formed to be connected to the antenna slots 138 respectively.

[0109] When observed from Figure 3 , a terminal coupling hole 148 for coupling the terminal portion 129 is formed at one end of the substrate 140 in the x-axis direction. Then, position fixing grooves 147 are formed at positions corresponding to the position fixing grooves 137 of the antenna module 130 on both sides of the substrate 140 in the y-axis direction.

[0110] On the other hand, referring to Figure 3 , Figure 5 and Figure 6 , on one side of the substrate 140, that is, from Figure 3When observing, the antenna chip 160 is mounted on the lower surface of the substrate 140. At this time, according to an embodiment of the present invention, the antenna chip 160 mounted on the lower surface of the substrate 140 can be a radar SoC (radar system-on-chip) as a single chip integrating RFIC and MCU. Accordingly, the antenna chip 160 according to an embodiment of the present invention can transmit and receive signals through a direct feeding method.

[0111] According to an embodiment of the present invention, the antenna chip 160 capable of transmitting and receiving signals through a direct feeding method is mounted on a substrate made of FR4 material. A feeding hole 145 is formed in the FR4 substrate 140, and then the antenna module 130 having an antenna waveguide 135 connected to the feeding hole 145 is coupled to the substrate 140, thereby forming a radar module assembly having a simple and compact structure.

[0112] In addition, the radar module assembly 100 according to an embodiment of the present invention forms a radar module by a direct feeding method, so that the induction range is wide and signal transmission and reception can be more accurate.

[0113] According to an embodiment of the present invention, a substrate support frame 150 is provided to support the substrate 140 and the antenna chip 160 mounted on the substrate 140.

[0114] Refer to Figure 3 and Figure 4 , the substrate support frame 150 includes: a bottom surface portion 152 formed of a quadrilateral plate member to form a bottom surface; and side wall portions 154 protruding in the z-axis direction from four corners of the bottom surface portion 152 to form side surfaces.

[0115] A border portion 156 is formed at the upper end portion of the side wall portion 154. In an embodiment of the present invention, the substrate 140 is coupled to the substrate support frame 150 through a fastening member 170 in a state where the perimeter portion of the substrate 140 contacts the border portion 156 of the substrate support frame 150.

[0116] Fastening holes 153 are formed at four corners of the border portion 156 of the plate support frame 150 to allow the fastening member 170 to be penetrated and coupled.

[0117] On the other hand, a through hole 152a is formed at the center portion of the bottom surface portion 152 of the substrate support frame 150 to allow the fastening member coupling protrusion 126b formed at the bottom surface portion of the housing 120 to penetrate and protrude.

[0118] Accordingly, in an embodiment of the present invention, the bottom surface portion 152 of the substrate support frame 150 is fixed in contact with the bottom surface portion 122 of the housing 120 in a state of being placed inside the first internal space 123 of the housing 120.

[0119] In an embodiment of the present invention, the antenna chip 160 mounted on the substrate may be located in the internal space surrounded by the bottom surface portion 152 and the side wall portion 154 of the substrate support frame 150.

[0120] In this specification, in order to distinguish the internal space formed in the substrate support frame 150 from the first internal space 123 inside the housing 120, the internal space of the substrate support frame 150 is named the second internal space 155. At this time, in order to support the antenna chip 160 mounted on the substrate 140, a protrusion 158 may be formed inside the second internal space 155 of the substrate support frame 150.

[0121] The protrusion 158 protrudes inward from the bottom surface portion of the substrate support frame 150, and the upper surface contacts the antenna chip 160 to support the antenna chip 160. Accordingly, the antenna chip 160 can be stably fixed in position inside the housing 120.

[0122] On the other hand, as shown in FIG. 3, a position fixing groove 157 is formed at a position corresponding to the position fixing groove 147 formed in the substrate 140 on the outer side of the substrate support frame 150 in the y-axis direction.

[0123] In addition, a terminal receiving groove 159 is formed on the outer side of the substrate support frame 150 in the x-axis direction to prevent the terminal portion 129 from being coupled to the substrate 140.

[0124] According to an embodiment of the present invention, when the radome 110 is coupled to the housing 120 in a state where the antenna module 130, the substrate 140, and the substrate support frame 150 are placed inside the housing 120, as Figure 5 shown, a radar module assembly 100 with a compact structure can be provided.

[0125] More specifically, as Figure 5 shown, the antenna module 130 having a substantially quadrilateral plate shape, the substrate 140 having a quadrilateral shape, and the substrate support frame 150 are located inside the first internal space 123 inside the housing 120, and the substrate 140 is directly connected to the terminal portion 129 formed in the housing 120 and then connected to the external terminal connection portion 128 on the outer side of the housing 120. Therefore, a radar module assembly 100 with a compact structure can be provided.

[0126] At this time, as Figure 6 shown, the radar module assembly 100 according to an embodiment of the present invention is such that a signal is directly generated by the radar SoC, transmitted through the transmitting unit 164 and the receiving unit 162, and signals are transmitted and received through the feeding hole 145, the waveguide 135, and the antenna slot 138. Therefore, the distance from the antenna chip 160 to the antenna slot 138 is short, there is no signal loss, and the signal propagation distance and resolution can be improved.

[0127] In addition, the structures of the antenna module 130, the substrate 140, and the substrate support frame 150 incorporated inside the housing 120 are simple and easy to fasten, so that the radar module assembly 100 can be manufactured at low cost.

[0128] As another embodiment of the present invention, instead of using a radar SoC with a direct feeding method, an antenna chip with an indirect feeding method can be used to form a radar module assembly. Hereinafter, the drawings will be changed to illustrate the radar module assembly according to the second embodiment of the present invention.

Figure 12 It is a schematic structural diagram for explaining the operation of a radar module assembly according to the second embodiment of the present invention.

[0130] Referring to Figures 7 to 12 , the radar module assembly 200 according to the second embodiment of the present invention may include: a housing 220, an antenna module 230, a substrate 240, a substrate support frame 250, and a radome 210.

[0131] Referring to Figure 7 and Figure 8 , similar to the radar module assembly according to the first embodiment of the present invention, the radar module assembly 200 according to the second embodiment can be modularized by fastening the antenna module 230, the substrate 240, and the substrate support frame 250 with fastening members such as screws.

[0132] At this time, the modularized antenna module 230, substrate 240, and substrate support frame 250 can be formed to be built inside the radome 210 and the housing 220 that form the outer shape of the radar module assembly 200.

[0133] Similar to the first embodiment, in the second embodiment of the present invention, the housing 220 is formed in a hexahedron shape and can be formed of a synthetic resin material such as plastic.

[0134] Referring to Figure 8 and Figure 11 , in the second embodiment of the present invention, the housing 220 includes: a bottom surface portion 222, which is formed in a quadrilateral plate shape forming the bottom surface of the housing 220; side wall portions 224, which extend upward from four corner portions of the bottom surface portion 222 to form four side walls.

[0135] At the upper end of the side wall portion 224, a radome coupling portion 225 is formed to protrude upward to be coupled to the side surface of the radome 210. The radome coupling portion 225 may be continuously formed to protrude along the upper circumference of the side wall portion of the housing so as to form a watertight structure inside the housing 220.

[0136] Refer to Figure 8 , a first internal space 223 is formed inside the housing 220, and the antenna module 230, the substrate 240, and the substrate support frame 250 can be placed therein.

[0137] In order to fix the positions of the antenna module 230, the substrate 240, and the substrate support frame 250 in a state where they are placed in the first internal space 223 without shaking, one or more position fixing protrusions 227 are formed on the inner surface of the side wall portion inside the housing.

[0138] When viewed from Figure 8 , the position fixing protrusions 227 are configured as strips extending in the z-axis direction and protrude toward the inside of the housing 220.

[0139] Corresponding to the formation positions of the position fixing protrusions 227, position fixing grooves 237, 247, and 257 are formed on the side surfaces of the antenna module 230, the substrate 240, and the substrate support frame 250. This structure may be the same as the structure described in the first embodiment.

[0140] In the second embodiment of the present invention, a terminal portion 229 is disposed on one side of the first internal space 223 of the housing 220. As Figure 8 and Figure 11 shown, the terminal portion 229 includes a plurality of pin members, and the plurality of pin members are formed such that one end portion faces upward from one end side in the x-axis direction of the first internal space 223 of the housing 220.

[0141] As Figure 11 shown, the other end portions of the plurality of pin members are formed to protrude by extending outward through the external terminal connection portion 228.

[0142] According to an embodiment of the present invention, when the antenna module 230, the substrate 240, and the substrate support frame 250 are placed in the first internal space 223 of the housing 220, the terminal coupling holes 248 of the substrate can be coupled to the terminal portion 229, and accordingly, the substrate 240 can be electrically connected to an external device of the housing 220 through the external terminal connection portion 228. This structure may be the same as the structure described in the first embodiment.

[0143] In the second embodiment of the present invention, fastening member coupling grooves 226a are formed at four corner portions of the first inner space 223 of the housing 120. Furthermore, the fastening members 270 for coupling the antenna module 230, the substrate 240, and the substrate support frame 150 can be stably coupled inside the first inner space 223 of the housing 220.

[0144] At this time, according to the second embodiment of the present invention, one or more fastening member coupling protrusions 226b are formed to protrude on the bottom surface 222 of the housing 220. At this time, different from the first embodiment, the fastening member coupling protrusions 226b according to the second embodiment are not arranged with two at the center portion of the bottom surface 222, but as Figure 8 shown, a plurality of fastening member coupling protrusions 226b are arranged at intervals from each other.

[0145] In the second embodiment of the present invention, the fastening member 270 is to penetrate and couple the four corner portions of the antenna module 230, the substrate 240, and the substrate support frame 250, and then can be coupled to the fastening member coupling grooves 226a formed at the four corners inside the first inner space 223 of the housing 220.

[0146] Then, on this basis, after penetrating the interiors of the antenna module 230, the substrate 240, and the substrate support frame 250, the penetrated fastening member 270 can be coupled to the plurality of fastening member coupling protrusions 226b formed to protrude on the bottom surface 122 of the housing 120.

[0147] At this time, the fastening member coupling grooves 226a formed at the four corner portions are holes for inserting the fastening member 270 formed at a predetermined height spaced upward from the bottom surface 222 of the housing 220, and a boss portion 221 of a predetermined height is formed on the inner side surface of the side wall portion 224 of the housing 220 along the fastening member coupling grooves 226a.

[0148] The boss portion 221 supports the border portion 256 formed along the outer perimeter of the substrate support frame 250 in a state where the substrate support frame 250 is coupled to the first inner space 223 of the housing 220. Accordingly, the substrate support frame 250 can be stably supported in the first inner space 223 of the housing 220 without shaking. This structure can be the same as that of the first embodiment.

[0149] Refer to Figure 8 and Figure 11 , the radome 210, as a cover for covering the antenna module 230, can be formed of an electrical insulator material. In the second embodiment of the present invention, the structure of the radome 210 is the same as that of the first embodiment, so the detailed description is replaced by the content described in the first embodiment.

[0150] Refer to Figure 9 and Figure 10, in the second embodiment of the present invention, the antenna module 230, the substrate 240, and the substrate support frame 250 are combined in a stacked manner inside the first internal space 223 of the housing 220.

[0151] Similar to the first embodiment, in the second embodiment of the present invention, the antenna module 230, the substrate 240, and the substrate support frame 250 are combined inside the first internal space 223 of the housing 220 in a state where they are integrated by the fastening member 270, or the antenna module 230, the substrate 240, and the substrate support frame 250 and the housing can also be combined simultaneously by the fastening member 270.

[0152] Refer to Figures 9 to 11 , the antenna module 230 according to the second embodiment of the present invention may include an antenna module main body 231 having a quadrilateral plate shape structure. At this time, the antenna module 230 may be formed of a synthetic resin material such as plastic, but the material of the antenna module 230 is not limited thereto. At this time, a gold plating layer may be formed on the outer surface of the antenna module main body 231.

[0153] In the second embodiment of the present invention, when viewed from Figure 9 , a plurality of antenna slots 238 are formed on the upper surface of the antenna module 230. The plurality of antenna slots 238 are connected to the waveguide 235 inside the antenna module 230 and can be connected to the feed holes 232 formed on the lower surface of the antenna module 230.

[0154] In the second embodiment of the present invention, 8 antenna slots 238 may be formed. Among the 8 antenna slots 238, 4 are used for transmission, and the remaining 4 may be used for reception. At this time, the shape, number, and position of the antenna slots may change according to the antenna design.

[0155] On the other hand, refer to Figure 10 , on the lower surface of the antenna module 230, that is, the surface adjacent to the substrate, a pair of spacing maintaining portions 234a, 234b are protrudingly formed.

[0156] The pair of spacing maintaining portions 234a, 234b are structures that protrude to maintain a predetermined distance between the substrate 240 on which the antenna chip 260 is mounted and one surface of the antenna module 230 main body. The pair of spacing maintaining portions 234a, 234b can be arranged side by side and spaced apart on both sides with the chip accommodation space 239 on which the antenna chip 260 is mounted as the center. The thickness of the pair of spacing maintaining portions 234a, 234b may be greater than the thickness of the antenna chip 260.

[0157] On the other hand, refer to Figure 10, on the lower surface of the antenna module 230, i.e., the surface adjacent to the substrate 240, a plurality of feeding holes 232 are formed. The plurality of feeding holes 232 are components formed to transmit the signals received and transmitted by the feeding lines formed on the substrate to the antenna slot 238 through the waveguide 235.

[0158] In an embodiment of the present invention, for the size, position, and shape of the feeding holes 232, various designs can be considered in consideration of the position of the feeding lines 261 formed on the substrate 240.

[0159] At this time, in the second embodiment of the present invention, in order to manufacture the antenna module 230 having the feeding holes 232, the waveguide 235 passing through the inside of the antenna module 230, and the antenna slot 238, the antenna module can be manufactured by laminating a plurality of plastic sheet members. However, the manufacturing method of the antenna module 230 is not limited thereto. For example, it can be manufactured by means such as 3D printing or various known methods.

[0160] At this time, the inside of the antenna slot 238, the waveguide 235, and the feeding holes 232 are gold-plated with metal, so that signals can be smoothly transmitted and received when the signals passing through the waveguide 235 are sent from the feeding holes 232 to the outside through the antenna slot 238 or received from the outside.

[0161] On the other hand, when observed from Figure 9 , position fixing grooves 237 are formed facing each other on both sides in the y-axis direction of the antenna module 230.

[0162] On the other hand, referring to Figure 11 , in an embodiment of the present invention, the substrate 240 coupled to the lower part of the antenna module 230 may be in a form in which an RFPCB substrate 240a and a PCB substrate 240b formed of FR4 material are laminated.

[0163] At this time, a radar SoC antenna chip 260 is installed on the upper part of the RFPCB substrate 240a, and a plurality of feeding lines 261 are formed to extend in the outer direction of the antenna chip from the antenna chip 260.

[0164] On the end side of each of the plurality of feeding lines 261, a transmitting terminal 264 for transmitting signals or a receiving terminal 262 for receiving signals may be formed.

[0165] At this time, the end portions of the feeding lines 261 are respectively located below the feeding holes 232 of the antenna module 230. In an embodiment of the present invention, since the substrate coupled to the lower part of the antenna module 230 is formed by laminating an RFPCB substrate and a substrate formed of FR4 material, the manufacturing cost of the radar can be saved, and the radar module assembly can have a simple structure.

[0166] Different from the first embodiment, in the second embodiment of the present invention, instead of only using a PCB substrate made of FR4 material, an RFPCB substrate is laminated to form a radar module assembly 200 in an indirect feeding manner. In order to shorten the height of the radar module assembly 200, an antenna chip 260 is arranged between the antenna module 230 and the substrate 240, and the thickness of the antenna module 230 is reduced, thereby forming a compact structure.

[0167] At this time, compared with the direct feeding method, the method of feeding the antenna chip 260 indirectly by extending the feeding line 261 to the peripheral part of the antenna chip 260 can slightly reduce the transceiver distance or resolution.

[0168] On the other hand, when viewed from Figure 9 a terminal bonding hole 248 for bonding the terminal part 229 is formed on one end side in the x-axis direction of the substrate. Then, position fixing grooves 247 are formed at positions corresponding to the position fixing grooves of the antenna module 230 on both sides in the y-axis direction of the substrate 240. This structure is the same as that of the first embodiment.

[0169] On the other hand, according to the second embodiment of the present invention, a substrate support frame 250 is provided to support the substrate 240 and the antenna chip 260 mounted on the substrate.

[0170] Referring to Figure 9 and Figure 10 , the substrate support frame 250 includes: a bottom surface portion 252, which is formed by a quadrilateral plate member to form a bottom surface; side wall portions 254, which protrude from the four corners of the bottom surface portion 252 in the z-axis direction to form side surfaces. A frame portion 256 is formed at the upper end portion of the side wall portions 254.

[0171] In an embodiment of the present invention, in a state where the perimeter portion of the substrate 240 contacts the frame portion 256 of the substrate support frame 250, the substrate 240 is coupled to the substrate support frame 250 through a fastening member 270.

[0172] Fastening holes 253 are formed at the four corners of the frame portion of the substrate support frame 250, and the fastening member 270 can be passed through and coupled.

[0173] On the other hand, a through hole 252a is formed at the center portion of the bottom surface portion 252 of the substrate support frame 250, so that the fastening member coupling protrusion 226b formed on the bottom surface portion 222 of the housing 220 can pass through and protrude. This structure is the same as that of the first embodiment.

[0174] Accordingly, in an embodiment of the present invention, the bottom surface portion 252 of the substrate support frame 250 is in contact with the bottom surface portion 222 of the housing 220 and is fixed in a state of being placed inside the first internal space 223 of the housing.

[0175] In the first embodiment of the present invention, the antenna chip 160 mounted on the substrate is located in the second internal space 155 surrounded by the bottom surface portion 152 and the side wall portion 154 of the substrate support frame 150. However, in the second embodiment of the present invention, the antenna chip 260 is mounted between the substrate 240 and the antenna module 230, so the chip may not be on the side of the second internal space.

[0176] As Figure 9 and Figure 11 shown, in the second embodiment of the present invention, in order to support the back side of the substrate 240 on which the antenna chip 260 is mounted, a protruding portion 258 is formed to protrude inside the second internal space 255 of the substrate support frame 250. Accordingly, the antenna chip 260 can be stably fixed in position inside the housing.

[0177] On the other hand, as Figure 9 shown, position fixing grooves 257 are formed at positions corresponding to the position fixing grooves 247 formed on the substrate 240 on both outer sides of the substrate support frame 250 in the y-axis direction.

[0178] In addition, in order not to interfere with the coupling of the terminal portion 229 to the substrate, a terminal receiving groove 259 is formed on the end side in the x-axis direction of the substrate support frame 250. This structure is the same as that of the first embodiment.

[0179] According to the second embodiment of the present invention, if the radome 210 is coupled to the housing 220 in a state where the antenna module 230, the substrate 240, and the substrate support frame 250 are placed inside the housing 220, then as Figure 11 shown, a radar module assembly with a compact structure can be provided.

The substrate 240 is directly connected to the terminal portion 229 formed on the housing 220 and then connected to the external terminal connection portion 228 on the outer side of the housing 220. Therefore, a radar module assembly with a compact structure can be provided.

[0181] At this time, as Figure 12 shown, the radar module assembly 200 according to an embodiment of the present invention is such that signals are transmitted from the radar SoC to the outside of the antenna chip through the feeding line, and the transmitted signals are sent to the outside through the feeding holes 232, the waveguides 235, and the antenna slots 238. At this time, since the thickness of the antenna module is thin, a radar module assembly with a compact structure can be provided.

[0182] In addition, the structures of the antenna module 230, the substrate 240, and the substrate support frame 250 incorporated inside the housing 220 are simple and easy to fasten, so that the radar module assembly can be manufactured at low cost.

[0183] According to the above structure, the radar module assembly according to an embodiment of the present invention is such that the antenna module is made into a plate shape using a synthetic resin material, and a waveguide is formed inside, and thus a waveguide antenna module having a thin thickness shape is provided, so that a compact structure can be formed.

[0184] According to an embodiment of the present invention, an antenna chip that can be directly fed is stacked on an FR4 PCB substrate and combined with the antenna module, and thus a radar module assembly that can be directly fed can be provided.

[0185] The radar module assembly according to an embodiment of the present invention is such that the antenna module, the substrate on which the chip is mounted, and the substrate support frame that supports the substrate can be directly combined with the housing of the radar structure, so that a simple structure can be assembled.

[0186] According to an embodiment of the present invention, in the case of manufacturing the radar module assembly in an indirect feeding manner, an RFPCB substrate and an FR4 PCB substrate are stacked to form a substrate, so that a radar module assembly having a compact structure can be provided.
