Description

AREA

[0002] Recently, the antennas used in radar devices have evolved from printed circuit boards (PCBs) to waveguide antennas.

[0003] A radar with waveguide antennas has a complex structure, combining an antenna structure—configured with an antenna slot connected to a waveguide—with a substrate that generates an RF signal. Therefore, there is a need to develop a waveguide antenna module with a simpler design.DE 10 2018 206 290 B3 discloses, for example, a radar sensor device for a motor vehicle, comprising a radar sensor and a radome through which radar signals from the radar sensor are irradiated in at least one transmission section, wherein the transmission section forms an outer surface of the motor vehicle or is adjacent to an outer surface formed by a support element of the motor vehicle, wherein the radome is thermally connected to the heat-generating radar sensor via a housing that surrounds the radar sensor at least laterally, wherein the radome and the housing each consist of a thermally conductive plastic compound with at least one matrix material and at least one filler that produces thermal conductivity or an amorphous plastic.

[0004] Furthermore, an antenna chip was recently developed that emits radio waves through a direct injection method, which differs from the indirect injection method of radar, which emits radio waves through a radio frequency (RF), and it is necessary to develop a radar module arrangement that can employ such an indirect injection method and a direct injection method.

[0053] As in Fig. As shown in Figures 1 to 6, a radar module arrangement 100 according to a first embodiment of the present disclosure can comprise a housing 120, an antenna module 130, a substrate 140, a substrate support frame 150 and a radome 110.

[0054] With reference to Fig. 1 and Fig. 2. The antenna module 130, the substrate 140, and the substrate support frame 150 of the radar module assembly 100 according to the first embodiment of the present disclosure can be modularized by fastening and assembling them using a fastener or fastening element 170, such as a screw. In other words, the antenna module 130, the substrate 140, and the substrate support frame 150 of the radar module assembly 100 can be assembled into a single module using the fastening element 170.

[0055] The antenna module 130, the substrate 140, and the substrate support frame 150, assembled and modularized to form a single module, can be referred to as an antenna module assembly. The modular antenna module 130, the substrate 140, and the substrate support frame 150 can be embedded in the radome 110 and the housing 120, which form the outer structure of the radar module assembly 100.

[0056] In one embodiment of the present disclosure, the housing 120 can, for example, have a substantially hexahedral shape and be formed from a synthetic resin material such as plastic.

[0057] Referring to Fig. 2 The housing 120 comprises a substantially rectangular, plate-shaped bottom / base section 122, which forms a bottom surface of the housing 120, and a side wall section 124, which extends in a z-axis direction from Fig. 2 (e.g. an upward or downward direction in Fig. 2) extends and forms four side walls on four sides or corners of the bottom / base section 122.

[0058] A radome coupling part 125, projecting upwards to couple with a lateral coupling section 114 of the radome 110, is designed to protrude from the upper end of the side wall section 124 of the housing 120. The projection of the radome coupling part 125 can be continuous along an upper circumference of the housing side wall section 124, so that the interior of the housing 120 can be watertight.

[0059] Inside the housing 120, a first interior space 123 is formed in which the antenna module 130, the substrate 140 and the substrate support frame 150 can be arranged.

[0060] One or more position fixing projections 127 are formed on the inner surface of the side wall section 124 inside the housing 120, so that the antenna module 130, the substrate 140 and the substrate support frame 150 are securely arranged in the first interior space 123 by being supported by the position fixing projections 127 without being movable.

[0061] For example, the position fixing projections 127 are in Fig. 2 are formed in the form of a rod extending in the direction of the z-axis and protrude from the inner surface of the housing 120.

[0062] Position fixing grooves 137, 147 and 157 respectively are formed on the side surfaces of the antenna module 130, the substrate 140 and the substrate support frame 150, which correspond to the position at which the position fixing projections 127 of the housing 120 are formed.

[0063] Accordingly, while the antenna module 130, the substrate 140 and the substrate support frame 150 are arranged in the first interior space 123 of the housing 120, the position fixing grooves 137, 147 and 157 are positioned so that they are in contact with the position fixing projections 127, and the antenna module 130, the substrate 140 and the substrate support frame 150 can be fixed without wobbling in the first interior space 123 of the housing 120.

[0064] On one side of the first interior space 123 of the housing 120 there is a connection unit 129.

[0065] The connection unit 129 includes a variety of pins, as shown in Fig. 2 shown, and first sections (e.g., first end sections) of the plurality of pins of the connection unit 129 protrude upwards from the first interior space 123 of the housing 120 (e.g., a side end of the first interior space 123 of the housing 120 with respect to the x-axis direction in Fig. 2).

[0066] Second sections (e.g., second end sections) of the plurality of pins of the connection unit 129 protrude from the housing 120 through an external connection section 128, as shown in Fig. 5 shown.

[0067] According to one embodiment of the present disclosure, when the antenna module 130, the substrate 140 and the substrate support frame 150 are mounted in the first interior space 123 of the housing 120, a connection coupling hole 148 in the substrate 140 can be coupled to the connection unit 129, and accordingly, the substrate 140 can be electrically connected to an external device located outside the housing 120 via the external connection section 128.

[0068] At four corners of the first interior space 123 of the housing 120 a coupling groove or fastening element coupling groove 126a is formed, so that the fastening or fastening element 170 for coupling the antenna module 130, the substrate 140 and the substrate support frame 150 can be connected to the interior of the first interior space 123 of the housing 120 without wobbling.

[0069] In this case, according to one embodiment of the present disclosure, one or more fastening projections or fastening element coupling projections 126b are designed such that they protrude from the bottom surface 122 of the housing 120.

[0070] In one embodiment of the present disclosure, the fastening element 170, which penetrates four corners of the antenna module 130, the substrate 140 and the substrate support frame 150, can be coupled to the fastening element coupling groove 126a, which is formed at four corners within the first interior space 123 of the housing 120.

[0071] Furthermore, the fastening or fastening element 170, which penetrates the antenna module 130, the substrate 140 and the substrate support frame 150, can also be coupled to one or more fastening projections or fastening element coupling projections 126b that protrude from the bottom surface 122 of the housing 120.

[0072] In this case, each of the fastening element coupling grooves 126a, which are formed at the four corners of the first interior 123 of the housing 120, is provided with a hole into which the fastening or fastening element 170 can be inserted at a height which is arranged at a predetermined distance upwards from the bottom surface 122 of the housing 120, and stepped sections 121 are formed on the inner surface of the side wall sections 124 of the housing 120 at the same height as an end of the coupling grooves or the fastening element coupling grooves 126a.

[0073] The stepped sections 121 support the edge region 156, which is formed along the outer circumference of the substrate support frame 150, in a state in which the substrate support frame 150 is connected to the first interior space 123 of the housing 120. Accordingly, the substrate support frame 150 can be mounted in the first interior space 123 of the housing 120 without wobbling or movement.

[0074] Furthermore, the outer surface of the substrate support frame 150 can have a square cross-section and be formed in a shape that essentially corresponds to the inner surface of the side wall part 124 of the first interior space 123 of the housing 120.

[0075] Accordingly, the outer surface of the substrate support frame 150 adjacent to the inner surface of the side wall section 124 of the first interior space 123 of the housing 120 can be arranged in a state in which the substrate support frame 150 is inserted into and secured in the first interior space 123 of the housing 120. Accordingly, the radar module assembly 100 can have a more compact structure.

[0076] Meanwhile, in one embodiment of the present disclosure, one or more connecting part projections or fastening element coupling projections 126b, which protrude from the lower surface section 122 of the housing 120, are arranged on both sides of the antenna chip 160 around or next to the antenna chip 160. Accordingly, the antenna chip 160 can be rigidly coupled to the substrate 140 and the antenna module 130 in a state in which the antenna module 130, the substrate 140 and the substrate support frame 150 are connected to the interior of the housing 120, so that the radar signal can be transmitted and received without interference.

[0077] With reference to Fig. 2 and Fig. 5. The radome 110 can be a cover for the antenna module 130, and the radome 110 can have an electrically insulating material.

[0078] In one embodiment of the present disclosure, the radome 110 comprises an upper plate section 112 having a substantially rectangular shape with a top surface oriented in the direction of the z-axis, as shown in Fig. 2 shown, and which is located on the top of the antenna module 130, which is provided within the radar module arrangement 100.

[0079] A lateral coupling element 114 is formed along the outer edges of the upper plate part 112. The lateral coupling element 114 has a downwardly open groove for coupling with a radome coupling element 125 of the housing 120.

[0080] The radome 110 can be designed with a material, size and shape such that signals from the outside of the radar module arrangement 100 can be transmitted and received without interference by the antenna module 130.

[0081] Referring to the Fig. 3 and Fig. 4 In one embodiment of the present disclosure, the antenna module 130, the substrate 140 and the substrate support frame 150 are arranged stacked within the first interior space 123 of the housing 120.

[0082] The antenna module 130, the substrate 140, and the substrate support frame 150 can be arranged within the first interior space 123 of the housing 120 in a state in which the antenna module 130, the substrate 140, and the substrate support frame 150 are integrally connected by the fastening or fastening element 170. Alternatively, the antenna module 130, the substrate 140, the substrate support frame 150, and the housing 120 can be coupled simultaneously by the fastening element 170 when connected to the first interior space 123 of the housing 120.

[0083] With reference to Fig. According to one embodiment of the present disclosure, the antenna module 130 can comprise an antenna module body 131, which is a rectangular, plate-shaped structure. The housing of the antenna module 131 can, for example, be made of a synthetic resin material such as plastic, but any other material can also be used for the housing of the antenna module 131. In this case, a plating layer can be formed on the outer surface of the antenna module body 131.

[0084] In one embodiment of the present disclosure, as in Fig. Figure 3 shows the multiple antenna slots 138 formed on the upper surface of the antenna module 130.

[0085] As in Fig. As shown in Figure 6, several antenna slots 138 are connected to a waveguide 135 located inside the antenna module 130, and to a waveguide connection opening 134 formed in a lower surface of the antenna module 130.

[0086] For example, the antenna slots 138 can have eight antenna slots, and four of the eight antenna slots 138 can be used for transmission and the remaining four of the eight antenna slots 138 for reception. The shape, number, and position of the antenna slots can vary depending on the antenna design of the radar module assembly 100.

[0087] As in Fig. As shown in Figure 4, the receiving groove 132 is formed on the lower surface of the antenna module 130, adjacent to the substrate 140. The receiving groove 132 can be formed with different depths and shapes on the underside of the antenna module 130 to avoid interference from a variety of electronic components provided in the substrate 140.

[0088] According to one embodiment of the present disclosure, the receiving groove 132 is formed on a surface of the antenna module 130 adjacent to the substrate 140 to avoid interference from the electronic components mounted on or contained therein, thereby reducing the overall thickness of the antenna module 130 and thus producing the antenna module 130 with a more compact size.

[0089] In one embodiment of the present disclosure, the size and position of the receiving groove 132 can be designed in various ways, taking into account the height of the components mounted on or contained in the substrate 140, and the antenna module 130 can be formed by a method for stacking a plurality of plastic plate elements. However, the manufacturing method of the antenna module 130 is not limited to this, and the antenna module 130 can, for example, be manufactured by 3D printing. Furthermore, the antenna module 130 can be manufactured using various known methods.

[0090] As in Fig. 3, Fig. 4 and Fig. As shown in Figure 6, the antenna slot 138, the waveguide 135, and the waveguide connection opening 134 are connected to an injection opening 145 in the substrate 140. A metal layer is formed inside the antenna slot 138, the waveguide 135, and the waveguide connection opening 134 to ensure smooth signal transmission and reception when signals traveling through the waveguide 135 are transmitted through the antenna slot 138 from the injection opening 145 to the exterior of the radar module assembly 100 or received by the exterior of the radar module assembly 100.

[0091] With reference to Fig. 3 and Fig. 4 The mounting hole 133 is designed to penetrate in the upper and lower direction (e.g. a direction perpendicular to a plane of the antenna module 130) so that the mounting or mounting element 170 can be connected to four corners of the antenna module 130 and a central section in which the antenna chip 160 is located.

[0092] Furthermore, as in Fig. Figure 3 shows a connection interference prevention groove 139 formed on the outside of the antenna module 130 in the direction of the x-axis to prevent interference in a state in which the connection unit 129 is connected to the substrate 140.

[0093] As in Fig. As shown in Figure 3, the position fixing grooves 137 are arranged opposite each other on both sides of the antenna module 130. For example, the position fixing grooves 137 are arranged such that they point in the direction of the y-axis from Fig. 3 are aligned with each other.

[0094] In one embodiment of the present disclosure relating to Fig. 3 and Fig. As referred to in Figure 4, the substrate 140, which is connected to the lower part of the antenna module 130, can be a printed circuit board (PCB) made of glass fiber reinforced epoxy laminate material (FR4). In one embodiment of the present disclosure, the substrate 140 connected to the lower part of the antenna module 130 is formed from the FR4 material, thereby reducing the manufacturing costs of the radar and simplifying the structure of the radar module assembly 100.

[0095] According to one embodiment of the present disclosure, a plurality of feed openings 145 are formed in a central subregion of the substrate 140. The plurality of feed openings 145 can be configured to form paths for transmitting or receiving signals that are fed directly from the antenna chip 160, and in the present embodiment, for example, eight feed openings 145 are configured to each be connected to the antenna slots 138.

[0096] Referring to Fig. 3 are located at an end section of substrate 140 (e.g., an end section in the direction of the x-axis of Fig. 3) Connection coupling holes 148 are provided for coupling with the connection unit 129. In addition, the position fixing grooves 147 on both sides are designed to correspond to the position fixing grooves 137 of the antenna module 130. The position fixing grooves 147 are arranged so that they point in the direction of the y-axis of Fig. 3 are aligned with each other.

[0097] Meanwhile, the antenna chip 160 is mounted on a surface of the substrate 140, e.g. on a lower surface of the substrate 140 in Fig. 3, see Fig. 3, Fig. 5 and Fig. 6. In this case, the antenna chip 160, which is mounted on the lower surface of the substrate 140, can, according to one embodiment of the present disclosure, be a single chip in which an integrated radio frequency integrated circuit (RFIC) and a microcontroller unit (MCU) are integrated, and can be a radar system on a chip (SoC). Accordingly, the antenna chip 160 can, according to one embodiment of the present disclosure, transmit and receive signals using a direct injection method.

[0098] According to one embodiment of the present disclosure, the antenna chip 160, which is configured to transmit and receive signals by the direct injection method, is mounted on the substrate 140 (e.g., a woven glass fiber substrate such as an FR4 material substrate), the injection opening 145 is formed in the substrate 140, and then the antenna module 130, which has the antenna waveguide 135 connected to the injection opening 145, is coupled to the substrate 140 so that the radar module arrangement 100 can have one.

[0099] Furthermore, according to an embodiment of the present disclosure, the radar module arrangement 100 forms a radar module by the direct injection method, so that the detection range of the radar can be extended and more accurate signal transmission and reception can be carried out.

[0100] According to one embodiment of the present disclosure, the substrate support frame 150 is provided to support the substrate 140 and the antenna chip 160 mounted on the substrate 140.

[0101] As in Fig. 3 and Fig. As shown in Figure 4, the substrate support frame 150 comprises a lower sub-section / base section 152 formed from a rectangular plate structure or element to form a bottom surface, and a side wall section 154 extending from the edges or four corners of the lower sub-section 152 in the direction of the z-axis to form a side wall or surface of the radar module assembly 100.

[0102] An edge region 156 is formed at an upper end part of the side wall section 154. The edge region 156 extends in a direction perpendicular to the side wall section 154, such as in the y-direction. Fig. 3. In one embodiment of the present disclosure, the substrate 140 is connected to the substrate support frame 150 by the fastening or fastening element 170, while an edge region of the substrate 140 is in contact with the edge region 156 of the substrate support frame 150.

[0103] Fastening holes 153 are formed on the edge section 156 of the substrate support frame 150, for example at four corners of the substrate support frame 150, where the edge area 156 of the substrate support frame 150 is formed, so that the fastening element 170 can be coupled through the fastening holes 153 of the substrate support frame 150.

[0104] Meanwhile, one or more through holes 152a are formed in a central part of the lower section 152 of the substrate support frame 150, so that the fastening element coupling projection 126b formed on the lower section of the housing 120 protrudes from and penetrates the through hole 152 of the substrate support frame 150.

[0105] Accordingly, in one embodiment of the present disclosure, the lower part 152 of the substrate support frame 150 can be mounted within the first interior space 123 of the housing 120 and attached to the lower part 122 of the housing 120 and be in contact with it.

[0106] In one embodiment of the present disclosure, the antenna chip 160 mounted on the substrate 140 can be positioned in the interior space surrounded by the lower part 152 and the side wall section 154 of the substrate support frame 150.

[0107] In one embodiment of the present disclosure, the interior space formed in the substrate support frame 150 is designated as the second interior space 155 to distinguish it from the first interior space 123 of the housing 120. A projecting section 158 can be formed in the second interior space 155 of the substrate support frame 150 to support the antenna chip 160 mounted on the substrate 140. The projecting section 158 can extend from the lower part 152 of the substrate support frame 150 toward the antenna chip 160.

[0108] The projecting section 158 extends inwards from the lower part of the substrate support frame 150, and an upper surface of the projecting section 158 contacts the antenna chip 160 to support the antenna chip 160. Accordingly, the antenna chip 160 can be positioned without wobbling inside the housing 120.

[0109] As in Fig. Figure 3 shows one or more position fixing grooves 157 formed at a position corresponding to the position fixing groove 147 formed in the substrate 140 on the outer surface of the substrate support frame 150. The position fixing grooves 157 are arranged such that they point in the direction of the y-axis of Fig. 3 are aligned with each other.

[0110] Furthermore, an end-receiving groove 159 is formed on the outer surface of the substrate support frame 150 in the direction of the X-axis in order not to impede the connection of the connection unit 129 with the substrate 140. For example, the end-receiving groove 159 in the y-direction of Fig. 3 be trained.

[0111] According to one embodiment of the present disclosure, the radome 110 is coupled to the housing 120, while the antenna module 130, the substrate 140 and the substrate support frame 150 are mounted inside the housing 120, so that the radar module assembly 100 can have a compact structure, as shown in Fig. 5 shown.

[0112] As in Fig. As shown in Figure 5, the size of the radar module arrangement structure 100 can be reduced because the generally rectangular, plate-shaped antenna module 130, the substantially rectangular substrate 140 and the substrate support frame 150 are arranged within the first interior space 123 of the housing 120 and the substrate 140 is directly connected to the connection unit 129, which is formed on or in the housing 120 and is connected to the external connection section 128 outside the housing 120.

[0113] As in Fig. As shown in Figure 6, the radar module arrangement 100 according to an embodiment of the present disclosure generates signals directly from the radar SoC and transmits and receives the signals through the feed opening 145, the waveguide 135 and the antenna slot 138 via the transmitter 164 and the receiver 162, so that a distance from the antenna chip 160 to the antenna slot 138 can be reduced, thereby improving the propagation distance and the resolution of the signals while reducing signal loss.

[0114] Furthermore, the structure in which the antenna module 130, the substrate 140 and the substrate support frame 150 are arranged within the housing 120 can be simpler and easier to attach, so that the radar module assembly 100 can be manufactured at a lower cost.

[0115] In a further embodiment of the present disclosure, a radar module arrangement can be configured using an indirect-feed antenna chip instead of a direct-feed radar SoC. A radar module arrangement according to a second embodiment of the present invention is described below.

[0116] Fig. Figure 7 is a perspective view of a radar module arrangement according to a second embodiment of the present disclosure. Fig. Figure 8 is a perspective exploded view of a radar module arrangement according to a second embodiment of the present disclosure. Fig. Figure 9 is a perspective exploded view of an antenna module of the radar module arrangement according to the second embodiment of the present disclosure. Fig. Figure 10 is a perspective exploded view of an antenna module of a radar module arrangement according to the second embodiment of the present disclosure. Fig. Figure 11 is a cross-sectional view of a radar module arrangement according to the second embodiment of the present disclosure. Fig. Figure 12 is a schematic configuration representation to describe the operation of the radar module arrangement according to the second embodiment of the present disclosure.

[0117] As in Fig. As shown in Figures 7 to 12, a radar module arrangement 200 according to the second embodiment of the present disclosure can comprise a housing 220, an antenna module 230, a substrate 240, a substrate support frame 250 and a radome 210.

[0118] Similar to the radar module arrangement according to the first embodiment of the present disclosure, the radar module arrangement 200 according to the second embodiment of the present disclosure can be modularized by fastening the antenna module 230, the substrate 240 and the substrate support frame 250 with a fastening or fastening element, e.g. a screw, as shown in Fig. 7 and Fig. 8 shown. In other words, the antenna module 230, the substrate 240 and the substrate support frame 250 of the radar module assembly 200 can be assembled into a single module using the fastening element 270.

[0119] In this case, the modularized antenna module 230, the substrate 240 and the substrate support frame 250 can be embedded in the radome 210 and the housing 220 to form the outer structure of the radar module assembly 200.

[0120] For example, in the second embodiment of the present disclosure, the housing 220 can, similar to the first embodiment, have a substantially hexahedral shape and be made of a synthetic resin material, such as plastic.

[0121] With reference to the Fig. 8 and Fig. 11 In the second embodiment of the present disclosure, the housing 220 comprises a substantially rectangular, plate-shaped lower sub-section / base section 222, which forms the bottom surface of the housing 220, and a side wall section 224, which extends upwards from four sides or corners of the lower sub-section / base section 222 to form four side walls of the radar module arrangement 200.

[0122] A radome coupling part 225, projecting upwards to couple with a lateral coupling part of the radome 210, is configured to protrude from the upper end of the side wall section 224 of the housing 220. The projection of the radome coupling part 225 can extend continuously along an upper circumference of the housing side wall section 224, so that the interior of the housing 220 can be watertight.

[0123] As in Fig. As shown in Figure 8, a first interior space 223 is formed inside the housing 220, in which the antenna module 230, the substrate 240 and the substrate support frame 250 can be arranged.

[0124] One or more positioning mounting projections 227 are formed on the inner surface of the side wall section inside the housing, so that the antenna module 230, the substrate 240 and the substrate support frame 250 are securely positioned in the first interior space 223 without being movable by being supported by the positioning mounting projections 227.

[0125] For example, the position fixing projections 227 are in Fig. 8 are formed in the form of a rod extending in the direction of the z-axis and protrude from the interior of the housing 220.

[0126] Position fixing grooves 237, 247 and 257 respectively are formed on the side surfaces of the antenna module 230, the substrate 240 and the substrate support frame 250, respectively, which correspond to the position at which the position fixing projections 227 of the housing 220 are formed. Such a structure can be the same or a similar structure to the structure described in the first embodiment.

[0127] In the second embodiment of the present disclosure, a connection unit 229 is located on one side of the first interior space 223 of the housing 220. The connection unit 229 comprises a plurality of pins, as shown in Fig. 8 and Fig. 11 shown, and first sections (e.g., first end sections) of the plurality of pins of the connection unit 229 protrude upwards from the first interior space 223 of the housing 220 (e.g., a side end of the first interior space 223 of the housing 220 with respect to the x-axis direction in Fig. 8).

[0128] Second sections (e.g., second end sections) of the plurality of pins of the connection unit 229 protrude from the housing 220 through an external connection section 228, as shown in Fig. 11 shown.

[0129] According to one embodiment of the present disclosure, when the antenna module 230, the substrate 240, and the substrate support frame 250 are mounted in the first interior space 223 of the housing 220, a connection coupling hole 248 of the substrate 240 can be coupled to the connection unit 229, and accordingly, the substrate 240 can be electrically connected via the external connection section 228 to an external device located outside the housing 220. Such a structure can be the same or a similar structure to the structure described in the first embodiment.

[0130] In the second embodiment of the present disclosure, a coupling groove or a fastening element coupling groove 226a is formed at four corners of the first interior space 223 of the housing 220, so that the fastening or fastening element 270 for connecting the antenna module 230, the substrate 240 and the substrate support frame 250 can be stably connected to the interior of the first interior space 223 of the housing 220.

[0131] In this case, according to the second embodiment of the present disclosure, one or more fastening projections or fastening element coupling projections 226b are configured to project from the bottom surface 222 of the housing 220. In contrast to the first embodiment, the fastening projections or fastening element coupling projections 226b according to the second embodiment cannot be located in the middle part of the lower part / base section 222, and as in Fig. As shown in Figure 8, the multitude of fastening element coupling projections 226b are spaced apart from each other.

[0132] In the second embodiment of the present disclosure, the fastening or fastening element 270, which penetrates four corners of the antenna module 230, the substrate 240 and the substrate support frame 250, can be coupled to the coupling groove for the fastening element or the fastening element coupling groove 226a, which is formed at four corners within the first interior space 223 of the housing 220.

[0133] Furthermore, the fastening or fastening element 270, which penetrates the antenna module 230, the substrate 240 and the substrate support frame 250, can also be coupled to one or more fastening projections or fastening element coupling projections 226b that protrude from the bottom surface 222 of the housing 220.

[0134] In this case, the fastening element coupling grooves 226a formed at the four corners are provided with a hole into which the fastening element 270 can be inserted at a height that extends upwards at a predetermined distance from the bottom surface 222 of the housing 220, and stepped sections 221 are formed on the inner surface of the side wall sections 224 of the housing 220 at the same height as one end of the coupling grooves or the fastening element coupling grooves 226a.

[0135] The stepped sections 221 support the edge region 256, which is formed along the outer circumference of the substrate support frame 250, in a state in which the substrate support frame 250 is connected to the first interior space 223 of the housing 220. Accordingly, the substrate support frame 250 can be mounted stably and without wobble in the first interior space 223 of the housing 220. Such a structure can be set up in the same way as in the first embodiment.

[0136] With reference to Fig. 8 and Fig. 11. The radome 210 can be a cover for the antenna module 230, and the radome 210 can comprise an electrically insulating material. In the second embodiment of the present disclosure, the structure of the radome 210 can be designed in the same or a similar manner to the structure of the radome 110 in the first embodiment, so that the detailed description thereof is replaced by the description of the contents of the first embodiment.

[0137] Referring to Fig. 9 and Fig. 10 In the second embodiment of the present disclosure, the antenna module 230, the substrate 240 and the substrate support frame 250 are arranged stacked within the first interior space 223 of the housing 220.

[0138] Similar to the first embodiment, in the second embodiment of the present disclosure, the antenna module 230, the substrate 240, and the substrate support frame 250 can be coupled to the first interior space 223 of the housing 220 in a state in which the antenna module 230, the substrate 240, and the substrate support frame 250 are integrally coupled by the fastening or fastening element 270. Alternatively, the antenna module 230, the substrate 240, the substrate support frame 250, and the housing can be coupled simultaneously by the fastening element 270 when they are connected to the first interior space 223 of the housing 220.

[0139] With reference to Fig. According to a second embodiment of the present disclosure, the antenna module 230 can comprise an antenna module body 231, which is a substantially rectangular, plate-shaped structure. The housing of the antenna module 230 can, for example, be made of a synthetic resin material such as plastic, but any other material can also be used for the antenna module 230. In this case, a plating layer can be formed on the outer surface of the antenna module body 231.

[0140] As in Fig. Figure 9 shows that in the second embodiment of the present disclosure, 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 a waveguide 235 located inside the antenna module 230, and to a waveguide connection opening 234 formed in a lower surface of the antenna module 230.

[0141] The antenna slots 238 can, for example, have eight antenna slots, with four of the eight antenna slots 238 being used for transmitting and the remaining four of the eight antenna slots 238 being used for receiving. The shape, position, and number of antenna slots can vary depending on the antenna design of the radar module assembly 200.

[0142] Meanwhile, a pair of slit presetting parts 234a and 234b protrudes from a lower surface of the antenna module 230, i.e., a surface adjacent to the substrate 240 (see Fig. 10).

[0143] The two slit-setting parts 234a and 234b project to maintain a constant distance between the substrate 240, on which the antenna chip 260 is mounted, and a surface of a body of the antenna module 230. The two slit-setting parts 234a and 234b are arranged such that they are spaced apart from each other on both sides of the chip receiving space 239, in which the antenna chip 260 is mounted. The thickness of the pair of slit-setting parts 234a and 234b (e.g., a thickness in the z-direction) can be greater than the thickness of the antenna chip 260.

[0144] Meanwhile, a plurality of feed-in openings 232 are formed on the underside of the antenna module 230, which borders the substrate 240 (see Fig. 10) The multiple feed openings 232 are components designed to transmit signals, which are transmitted and received from a feed line formed in the substrate 240, via the waveguide 235 to the antenna slot 238.

[0145] In one embodiment of the present disclosure, the size and shape of the feed openings 232 can be designed in various ways, taking into account the position of the supply line 261 formed in the substrate 240.

[0146] In the second embodiment of the present disclosure, the antenna module 230 can be manufactured by a method in which a plurality of plastic plate elements are stacked to produce the antenna module 230 with the feed openings 232, a waveguide 235 running inside the antenna module 230, and an antenna slot 238. However, the manufacturing method of the antenna module 230 is not limited to this, and the antenna module 230 can, for example, be manufactured by 3D printing or other known methods.

[0147] In this case, the inside of the antenna slot 238, the waveguide 235 and the feed opening 232 is coated with metal to ensure smooth transmission and reception of signals when the signals passing through the waveguide 235 are transmitted through the antenna slot 238 from the feed opening 232 to the outside of the radar module assembly 200 or are received from the outside of the radar module assembly 200.

[0148] As in Fig. As shown in Figure 9, the position fixing grooves 237 are arranged opposite each other on both sides of the antenna module 230. For example, the position fixing grooves 237 are arranged such that they point in the direction of the y-axis from Fig. 9 are aligned with each other.

[0149] In one embodiment of the present disclosure relating to Fig. 11 refers to the substrate 240, which is connected to the lower part of the antenna module 230, which can be formed by stacking the high-frequency printed circuit board substrate (PCB) 240a and the PCB substrate 240b made of a woven glass fiber material, such as glass fiber reinforced epoxy laminate (FR4).

[0150] In this case, a radar SoC antenna chip 260 is mounted on the upper section of the RF printed circuit board substrate 240a, and a plurality of leads 261 are configured to extend outwards from the antenna chip 260.

[0151] At each end of the multitude of feed lines 261, a transmission port 264 for transmitting signals or a receiving port 262 for receiving signals can be formed.

[0152] In this case, the end sections of the leads 261 are located below the feed holes 232 of the antenna module 230. In one embodiment of the present disclosure, the substrate 240 connected to the lower section of the antenna module 230 is formed by stacking the RF printed circuit board substrate 240a and the PCB substrate 240b made of a woven glass fiber material, thereby reducing the manufacturing costs of the radar and simplifying the structure of the radar module arrangement 200.

[0153] In the second embodiment of the present disclosure, in contrast to the first embodiment, the RF printed circuit board substrate 240a is stacked without using a single FR4 material printed circuit board substrate, and the radar module assembly 200 is configured by an indirect feed method. However, in order to reduce the height of the radar module assembly 200, the antenna chip 260 is positioned between the antenna module 230 and the substrate 240, so that the thickness of the antenna module 230 can be reduced to make the radar module assembly 200 more compact.

[0154] In this case, the method of extending the feed lines 261 to the edge of the antenna chip 260, so that they can be used in the indirect feed method, may have a slightly smaller transmit / receive distance or a lower resolution than the direct feed method.

[0155] As in Fig. As shown in Figure 9, the connection coupling hole 248 is for coupling with the connection unit 229 at one end side of the substrate 240 (e.g., an end section in the direction of the x-axis of Fig. 9) formed. In addition, a position fixing groove 247 is formed on both sides of the substrate 240 at a location that corresponds to the position fixing groove 237 of the antenna module 230. The position fixing grooves 247 are arranged such that they point in the direction of the y-axis of Fig. 9 are aligned with each other. Such a structure according to the second embodiment can be designed in the same or a similar way to the configuration of the first embodiment.

[0156] According to the second embodiment of the present disclosure, the substrate support frame 250 is provided to support the substrate 240 and the antenna chip 260 mounted on the substrate 240.

[0157] As in Fig. 9 and Fig. As shown in Figure 10, the substrate support frame 250 comprises a base section 252, which is formed from a rectangular plate structure or element to form a base surface, and a side wall section 254, which projects from four sides or corners of the base section 252 in the direction of the z-axis to form a side wall of the surface of the radar module assembly 200. An edge region 256 is formed at an upper end part of the side wall section 254. The edge region 256 extends in a direction perpendicular to the side wall section 254, such as in the y-direction. Fig. 9.

[0158] In one embodiment of the present disclosure, the substrate 240 is connected to the substrate support frame 250 by the fastening or fastening element 270, while an edge region of the substrate 240 touches an edge region 256 of the substrate support frame 250.

[0159] Fastening holes 253 are formed on the edge section 256 of the substrate support frame 250, for example at four corners of the substrate support frame 250, where the edge area 256 of the substrate support frame 250 is formed, so that the fastening or fastening element 270 can be coupled through the fastening holes 253 of the substrate support frame 250.

[0160] Meanwhile, one or more through-holes 252a are formed in a central part of the bottom section 252 of the substrate support frame 250, so that the fastening element coupling projection 226b, which is formed on the lower part 222 of the housing 220, projects through and penetrates the through-hole 252 of the substrate support frame 250. Such a structure can be formed in the same or a similar way as the structure of the first embodiment.

[0161] Accordingly, in one embodiment of the present disclosure, the lower part 252 of the substrate support frame 250 can be mounted within the first interior space 223 of the housing 220 and attached to the lower part 222 of the housing 220 and be in contact with it.

[0162] In the first embodiment of the present disclosure, the antenna chip 160 mounted on the substrate 140 is positioned in the second interior space 155, which is surrounded by the lower part 152 and the side wall section 154 of the substrate support frame 150. In the second embodiment of the present disclosure, however, the antenna chip 260 is located between the substrate 240 and the antenna module 230, so that the antenna chip 160 cannot be positioned in the second interior space 155.

[0163] As in Fig. 9 and Fig. As shown in Figure 11, in the second embodiment of the present disclosure, a projecting section 258 can be formed within the second interior space 255 of the substrate support frame 250 to support the opposite surface of the substrate 240 on which the antenna chip 260 is mounted. Accordingly, the antenna chip 260 can be positioned without wobbling inside the housing. The projecting section 258 can extend from the lower part 252 of the substrate support frame 250 towards the antenna chip 260.

[0164] As in Fig. Figure 9 shows one or more position fixing grooves 257 formed at a position corresponding to the position fixing groove 247 formed in the substrate 240 on the outer surface of the substrate support frame 250. The position fixing grooves 257 are arranged such that they point in the direction of the y-axis of Fig. 9 are aligned with each other.

[0165] Furthermore, an end-receiving groove 259 is formed on the end side of the substrate support frame 250 in the x-direction to ensure that the connection of the connection unit 229 to the substrate 240 is not impaired. For example, the end-receiving groove 259 in the y-direction of Fig. 9. Such a structure can be designed in the same or a similar way to the structure of the first embodiment.

[0166] According to the second embodiment of the present disclosure, the radome 210 is coupled to the housing 220, while the antenna module 230, the substrate 240 and the substrate support frame 250 are mounted inside the housing 220, so that the radar module assembly 200 can have a compact structure, as shown in Fig. 11 shown.

[0167] As in Fig. As shown in Figure 10, the size of the radar module arrangement structure 200 can be reduced because the generally rectangular, plate-shaped antenna module 230, the substantially rectangular substrate 240 and the substrate support frame 250 are arranged within the first interior space 223 of the housing 220 and the substrate 240 is directly connected to the connection unit 229, which is formed on or in the housing 220 and is connected to the external connection section 228 outside the housing 220.

[0168] As in Fig.As shown in Figure 12, the radar module arrangement 200 according to an embodiment of the present disclosure can transmit and receive signals from the radar SoC to the outside of the antenna chip 260 via the feed line, and transmit and receive signals to and from the outside of the antenna chip 260 via the feed opening 232, the waveguide 235, and the antenna slot 238. Therefore, the thickness of the antenna module 230 can be reduced, allowing the radar module arrangement 200 to have a more compact structure.

[0169] Furthermore, the structure in which the antenna module 230, the substrate 240 and the substrate support frame 250 are arranged within the housing 220 can be simpler and easier to attach, so that the radar module arrangement can be manufactured at a lower cost.

[0170] Therefore, according to some embodiments of the present disclosure, a radar module arrangement can have a more compact structure, since it includes a thinner waveguide antenna module by manufacturing an antenna module in a plate form using a resin material and forming a waveguide therein.

[0171] According to certain embodiments of the present disclosure, a radar module arrangement can be coupled with an antenna module by stacking an antenna chip capable of direct feed onto a substrate such as a glass fiber reinforced epoxy laminate material (FR4) as a printed circuit board substrate, thereby enabling direct feed.
