Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of Korean Patent Application No. 10-2021-0026237, filed with the Korean Intellectual Property Office on February 26, 2021, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] The following description relates to an antenna module and an antenna device having the antenna module. Background Technology

[0004] An antenna is a conductor-based component that radiates radio waves to or receives radio waves from other locations to achieve communication purposes in wireless communication, and can be used in a variety of products such as wireless telegraphy, wireless telephone, radio, and television. An antenna assembly consists of an antenna and a substrate.

[0005] With the recent demand for high-quality multimedia services using wireless mobile communication technologies, there is a need for next-generation wireless transmission technologies that can transmit larger amounts of data faster with lower error rates.

[0006] Meanwhile, 5G antennas use a frequency band of 6 GHz or less (FR1) and a millimeter wave frequency band (FR2). Here, the FR1 operating band uses a low and wide frequency band of 410 MHz to 7125 MHz.

[0007] Because the FR1 uses a very wide band as described above, the antenna device is made of a combination of several antennas. For example, the frequency band is divided into a low band of 617 to 960 MHz, a mid band of 1427 to 2690 MHz, and a high band of 3300 to 7125 MHz, and the antenna device is formed by a combination of antennas supporting the corresponding divided bands.

[0008] Therefore, the design of antennas to support broadband 5G frequencies is required.

[0009] The above description is information acquired or already possessed by the inventors during the process of conceiving this disclosure, and is not necessarily technology known prior to the filing of this application. Summary of the Invention

[0010] An example embodiment provides an antenna module for supporting 5G NR frequencies and an antenna device having the antenna module.

[0011] The technical tasks available from this disclosure are not limited to those mentioned above. Furthermore, those skilled in the art to which this disclosure pertains will clearly understand other unmentioned technical tasks from the following description.

[0012] An antenna module and an antenna device having the antenna module will be described according to an example embodiment.

[0013] The antenna module includes: antenna material formed of a metallic material and having a half-plane inverted-F antenna (PIFA) structure; and a support member formed in the shape of a hexahedron with sides and a bottom, the sides and bottom being bent from the antenna material by stamping, wherein the support member and the antenna material are formed as a single body.

[0014] The support may include first to fourth skirt patterns that bend at right angles from four edge portions of the antenna material and a fifth skirt pattern that forms the bottom surface of a hexahedron, wherein the first to fourth skirt patterns may extend to the antenna material at their respective upper ends and are separated from each other at two side ends.

[0015] The antenna material can be assembled to be spaced parallel to the mounting surface of the substrate, and the antenna module can be a monopole antenna that provides power to a single feeder formed in the fifth skirt pattern.

[0016] The first skirt pattern can form the front of a hexahedron and is formed on the upper left side relative to the feeder. The feeder can extend to the lower end of the first skirt pattern.

[0017] The fifth skirt pattern may further include a first mounting portion mounted on a substrate and a second mounting portion mounted on an additional mounting pattern formed on the substrate. The feed, the first mounting portion, and the second mounting portion may be formed to be separate from each other on the same plane. The first mounting portion may extend to the lower end of the second skirt pattern forming the hexahedron. The second mounting portion may extend to the lower end of the fourth skirt pattern forming the right side face of the hexahedron. The fourth skirt pattern may include: an upper skirt that extends to the antenna material at its upper end; and a lower skirt that extends to the second mounting portion at its lower end and to the second skirt pattern at its side end.

[0018] The upper and lower skirts can be formed to be separated from each other along the height direction on the same plane. The third skirt pattern can be formed as the left side face of a hexahedron and can be formed to have a shorter length than the first skirt pattern.

[0019] Meanwhile, the antenna device includes: an antenna module comprising antenna material and a support member, the support member being formed in the shape of a hexahedron having sides and a bottom surface, the sides and bottom surface being bent from the corresponding edges of the antenna material by stamping; and a substrate on which the antenna module is mounted.

[0020] The antenna material can be mounted in a way that is parallel to the mounting surface of the substrate by means of a support, and the antenna module can be a monopole antenna in which a single feeder is formed on the bottom surface of the antenna module.

[0021] The support may include first to fourth skirt patterns that bend at right angles from four edge portions of the antenna material and a fifth skirt pattern that forms the bottom surface of a hexahedron, wherein the fifth skirt pattern may include: a feeder that extends to the lower end of the first skirt pattern; a first mounting portion that extends to the lower end of the second skirt pattern; and a second mounting portion that extends to the lower end of the fourth skirt pattern.

[0022] The substrate may include: a feed region including multiple patterns on which an antenna module is mounted; a junction region including connection patterns for feeding the antenna module; and matching circuitry formed on the connection patterns. The feed region may include a mounting pattern on which a first mounting portion is mounted, an additional mounting pattern on which a second mounting portion is mounted, and a feeder pattern on which a feeder is mounted.

[0023] The matching circuit may be configured to optionally connect the connection pattern and the grounding area to the feed pattern. The matching circuit may include: a shunt non-connector (NC) disposed across the feed pattern and the grounding area and not electrically connected to the feed pattern and the grounding area; a series inductor that connects the feed pattern and the connection pattern in series; and a shunt inductor that connects the connection pattern and the grounding area. A gap may be formed between the end portions of the antenna module and the grounding area.

[0024] Additional aspects of the exemplary embodiments will be set forth in part in the description which follows, and will be apparent in part from the description, or may be learned by practice of this disclosure.

[0025] According to an example embodiment, the antenna device can use a single component (antenna module) to form a 5G NR antenna that supports the operating bands of low-band, mid-band, and high-band FR1.

[0026] In addition, the antenna module is formed into a hexahedral shape by stamping a single metal plate, and thus can be easily manufactured and assembled at a reduced cost, and can be fitted in three locations, thereby improving mechanical strength.

[0027] Additionally, the antenna device can have a semi-PIFA structure because the matching circuit based on a monopole antenna with a single feeder can be applied to the antenna device.

[0028] In addition, the antenna device can have a wideband low resonant frequency and improve radiation efficiency in the low frequency band.

[0029] The effects of the antenna module and the antenna device having the antenna module are not limited to those mentioned above. Furthermore, those skilled in the art to which this disclosure pertains will clearly understand from the foregoing description other effects not mentioned. Attached Figure Description

[0042] In the following text, reference will be made to Figures 1 to 5 This describes the antenna module 100 and the antenna device 10 having the antenna module 100. For reference, Figure 1 and Figure 2 This is a perspective view of the antenna module 100, and... Figure 3 This is a perspective view of the antenna device 10. Figure 4 This is a plan view of substrate 200 according to an example embodiment, and, Figure 5 yes Figure 4 A magnified view of part of the letter "A".

[0043] Referring to the accompanying drawings, the antenna device 10 includes an antenna module 100 and a substrate 200.

[0044] First, refer to Figure 1 and Figure 2 To describe antenna module 100.

[0045] The antenna module 100 includes an antenna material 110 and a support member 120. The antenna material 110 and the support member 120 are formed into a hexahedral shape by stamping a sheet of metal material and are integrally formed into a single component.

[0046] The following description will be based on Figure 1The antenna module 110 shown is provided in a state that is based on the orientation. Figure 1 The front-to-back axis, left-to-right axis, and up-down axis are shown in the diagram.

[0047] Antenna module 100 is a 5G NR antenna and supports the first frequency band FR1 in the range of 617 MHz to 7125 MHz. Furthermore, the 617 to 7125 MHz frequency band (corresponding to the operating band of FR1) can be divided into three bands: a low band of 617 to 960 MHz, a mid band of 1427 to 2690 MHz, and a high band of 3300 to 7125 MHz. Antenna module 100 can support all the divided frequency bands. That is, antenna module 100 can support the 617 to 7125 MHz (FR1 operating band) using a single antenna material 110.

[0048] Additionally, the antenna module 100 includes a single feeder as a monopole antenna and is formed by a half-plane inverted-F antenna (PIFA).

[0049] The antenna material 110 is formed on the top surface of a hexahedron and is mounted parallel to and spaced apart from the mounting surface of the substrate 200.

[0050] The support member 120 is the portion mounted between the antenna material 110 and the substrate 200, and the four edge portions of the antenna material 110 can be formed into a single body by bending it downwards at substantially right angles via stamping. Furthermore, each surface of the support member 120 can be formed into a flat plate shape. Here, "right angle" does not necessarily refer to 90 degrees.

[0051] The support member 120 sequentially includes a first skirt pattern 121 forming the front of a hexahedron, a second skirt pattern 122 forming the rear, a third skirt pattern 123 forming the left side, a fourth skirt pattern 124 forming the right side, and a fifth skirt pattern 125 forming the bottom.

[0052] The first to fourth skirt patterns 121, 122, 123 and 124 extend to the antenna material 110 at their respective upper ends, but are separated from each other at their two side ends. That is, the first to fourth skirt patterns 121, 122, 123 and 124 are formed to be separated from the adjacent surfaces.

[0053] The first skirt pattern 121 extends from the top face to the bottom face of the hexahedron, specifically extending to the antenna material 110 at the upper end and to the fifth skirt pattern 125 at the lower end. Furthermore, the first skirt pattern 121 is formed on the upper left side relative to the feeder 125c. This causes the direction of the current supplied from the feeder 125c to the antenna module 100 to increase to the left and the current flow to make a large turn.

[0054] The size and length of the first skirt pattern 121 can produce a high band resonant frequency and improve the Q value of the impedance.

[0055] The second skirt pattern 122 is formed parallel to the first skirt pattern 121, and extends to the antenna material 110 at the upper end and to the fifth skirt pattern 125 at the lower end.

[0056] The second skirt pattern 122 creates a gap coupling effect with the antenna material 110. Furthermore, the second skirt pattern 122 is the largest in size in the support 120 and corresponds to the substrate 200 in length (i.e., the length of the bottom end), thus generating low-band resonant frequencies and mid-band resonant frequencies and improving the Q value of the impedance.

[0057] The third skirt pattern 123 extends to the antenna material 110 at the upper end, but extends to the middle along the height direction of the hexahedron at the lower end, and therefore does not extend to the bottom.

[0058] By adjusting the size and length of the third skirt pattern 123, a high-band resonant frequency can be generated.

[0059] In addition, since the third skirt pattern 123 is only constrained at the upper end and free at the lower end, the length and size of the third skirt pattern 123 can be easily adjusted.

[0060] The fourth skirt pattern 124 is formed parallel to the third skirt pattern 123 and is divided into an upper skirt 124a extending to the antenna material 110 and a lower skirt 124b extending to the fifth skirt pattern 125.

[0061] In addition, the upper skirt 124a and the lower skirt 124b are formed separately on the same plane, and their end portions are formed to be spaced apart from each other on one side along the height direction of the hexahedron.

[0062] Here, the gap coupling effect can occur between the antenna material 110 and the lower skirt 124b.

[0063] The fifth skirt pattern 125 is vertically curved toward the inside of the hexahedron at the lower ends of the skirt patterns 121, 122, and 124 that form the sides, to form the bottom side of the hexahedron. The fifth skirt pattern 125 includes a first assembly portion 125a, a second assembly portion 125b, and a feeder 125c.

[0064] The first assembly portion 125a extends to the lower end of the second skirt pattern 122 and bends vertically forward at the lower end of the second skirt pattern 122. The first assembly portion 125a extends to the lower end of the second skirt pattern 122 and thus can be relatively large in both area and length.

[0065] The second assembly portion 125b extends to the lower end of the lower skirt portion 124b of the fourth skirt pattern 124, and bends vertically to the left at the lower end of the lower skirt portion 124b.

[0066] The feeder 125c extends from the lower end of the first skirt pattern 121 and is formed at a position substantially parallel to the first assembly portion 125a by bending the lower end of the first skirt pattern 121 vertically toward the rear.

[0067] Here, the feeder 125c can be bent at the lower end of the first skirt pattern 121 in multiple steps.

[0068] Furthermore, in the fifth skirt pattern 125, the first assembly portion 125a, the second assembly portion 125b, and the feeder 125c are formed to be separated from each other on the same plane.

[0069] The fifth skirt pattern 125 is a portion that is essentially mounted on the mounting surface of the substrate 200, and the antenna module 100 is fastened to the substrate 200 at three locations: the first mounting portion 125a, the second mounting portion 125b, and the feeder 125c, thereby achieving stable fastening and high mechanical strength.

[0070] Furthermore, the fifth skirt pattern 125 can be mounted on the substrate 200 using surface mount technology (SMT).

[0071] According to an example embodiment, the antenna module 100 can support low-band and mid-band frequencies by adjusting the size and length of the second skirt pattern 122, and high-band frequencies by adjusting the size and length of the first skirt pattern 121, the third skirt pattern, and the fourth skirt pattern 124. Therefore, the antenna module 100 can support a frequency band in the range of 617 to 7125 MHz, which is the operating band of FR1 in 5G NR.

[0072] In addition, since the antenna material 110 and the first to fourth skirt patterns 121, 122, 123 and 124 (excluding the fifth skirt pattern 125) are all set to float on the substrate 200, the antenna module 100 can disperse the polarization direction of the radiated radio waves and widen the radiation range.

[0073] In addition, the antenna module 100 has a hexahedral shape, and thus a gap coupling effect can be generated between the antenna material 110 and the support member 120, and this effect can be used to configure it as a monopole antenna.

[0074] Furthermore, the antenna module 100 is manufactured by stamping a sheet of metal material, and therefore can be easily manufactured with low production costs. Additionally, the antenna module 100 can be easily assembled using SMT or similar methods.

[0075] Next, we will refer to Figures 3 to 5 The antenna device 10 and the substrate 200 on which the antenna module 100 described above is mounted are described.

[0076] The substrate 200 includes a grounding area 220 and a feed area 210 on which the antenna module 100 is mounted. For example, the substrate 200 is an evaluation board and may be an apparatus for RF testing of the antenna module 100.

[0077] Here, the substrate 200 may be integrally formed with a metal layer or circuit on a printed circuit board (PCB). Although the accompanying drawings show the substrate 200 in the shape of a rectangular plate, the shape of the substrate 200 is merely an example for ease of description and can be changed in a variety of ways.

[0078] The feed area 210 may include multiple patterns, such as mounting pattern 211, feeder pattern 213, and additional mounting pattern 212, which are formed by conductors that allow feeding when the antenna module 100 is mounted thereon.

[0079] The first assembly part 125a is assembled onto the assembly pattern 211, thereby physically securing the antenna module 100. Furthermore, the assembly pattern 211 is formed to be longer than the additional assembly pattern 212.

[0080] The feeder 125c is mounted on the feeder pattern 213 such that the feeder pattern 213 is connected to the extension pattern 230 to supply power to the antenna module 100 via the feeder 125c.

[0081] The second assembly part 125b is assembled on an additional assembly pattern 212 located between the assembly pattern 211 and the feeder pattern 213.

[0082] The additional assembly pattern 212 extends the physical length of the fourth skirt pattern 124, thereby allowing the formation of a low-band resonant frequency.

[0083] A feeder pattern 213 for supplying power to the antenna module 100 and an extension pattern 230 for connecting an external power source (not shown) may be formed in the grounding area 220, and a matching circuit 240 may be formed on the extension pattern 230.

[0084] Here, the feeder pattern 213 extends toward the contact area 220, and the matching circuit 240 is configured to connect the extended end portion of the feeder pattern 213 with the extended pattern 230.

[0085] refer to Figure 5 The matching circuit 240 includes a shunt non-connector (NC) 241, a series inductor 242, and a shunt inductor 243.

[0086] The branch NC 241 is set across feeder pattern 213 and grounding area 220, but is not electrically connected to feeder pattern 213 and grounding area 220.

[0087] The series inductor 242 is configured to connect the feeder pattern 213 and the extension pattern 230 in series.

[0088] The shunt inductor 243 is configured to connect the extension pattern 230 and the grounding area 220.

[0089] Matching circuit 240 is configured in reverse coupling within antenna module 100 in the sequence of feed pattern 213, shunt NC 241, series inductor 242, and shunt inductor 243. Furthermore, matching circuit 240 can generate mid-band and high-band resonant frequencies through the harmonic effect of the low-band resonant frequency, thereby improving the impedance and bandwidth of the low-band resonant frequency.

[0090] The antenna device 10 is formed by mounting the antenna module 100 on the feed region 210 of the substrate 200.

[0091] Here, the antenna device 10 may have a semi-PIFA structure because a matching circuit based on a monopole antenna with a single feeder can be applied to the antenna device 10.

[0092] That is, the antenna device 10 can be configured as a monopole antenna by the gap coupling effect generated between the various skirt patterns 122, 123, 124 in the antenna module 100 formed in a hexahedral shape and the antenna material 110. Furthermore, the antenna device 10 can form a PIFA antenna, wherein the first skirt pattern 121 is coupled to the feeder 125c to serve as the feed portion, and the antenna material 110, the second to fifth skirt patterns 122, 123, 124 and 125, and the assembly pattern 211 of the substrate 200 serve as the antenna body.

[0093] In addition, the antenna device 10 can be formed into an antenna module 100 in the shape of a hexahedron, thereby generating a wideband low resonant frequency, and generating a midband resonant frequency and a high band resonant frequency through the frequency doubling effect of the primary low band resonant frequency, thereby improving the impedance and bandwidth of the low band resonant frequency.

[0094] Here, since the antenna device 10 is a monopole antenna, the distance from the antenna material 110 to the second skirt pattern 122, the first mounting portion 125a, and the mounting pattern 211 is one-quarter of the wavelength of the first resonant frequency. Furthermore, in the antenna device 10, the distance from the antenna material 110 to the second skirt pattern 122, the lower skirt 124b, the second mounting portion 125b, and the additional mounting pattern 212 is one-quarter of the wavelength of the second resonant frequency.

[0095] In this way, the antenna device 10 acts as a support for all low-band, mid-band, and high-band 5G NR antennas by means of the distance between the antenna module 100 and the assembly patterns 211 and 212 of the substrate 200.

[0096] Additionally, the antenna device 10 includes a gap 221 formed when the antenna module 100 and the grounding area 220 are spaced apart by a predetermined distance. By adjusting the gap 221, it is possible to form an antenna device 10 with a wideband low resonant frequency and improve radiation efficiency in the low-frequency band.

[0097] Meanwhile, although the antenna module 100 is manufactured using stamping in the above example embodiment, laser direct structuring (LDS) may alternatively be used.

[0098] While this disclosure includes specific examples, it will be apparent to those skilled in the art that various changes in form and detail may be made in these examples without departing from the spirit and scope of the claims and their equivalents. The examples described herein are to be considered in a descriptive sense only and not for limiting purposes. The description of features or aspects in the various examples will be considered applicable to similar features or aspects in other examples. For example, suitable results may be achieved if the described technology is performed in a different order and / or if the components in the described system, architecture, apparatus, or circuit are combined in a different manner and / or replaced or supplemented by other components or their equivalents.
