Abstract
Description
Technical Field
[0001] The present invention relates to an antenna module, and more specifically to an antenna module capable of overcoming radiation space constraints by using a coupling radiation part and an electronic device including the same. It is an invention.
Background Art
[0002] In recent years, the thickness of TVs has been decreasing, and the space between the TV and the wall surface has been gradually decreasing. As the TV becomes thinner and closer to the wall surface, especially when the TV is mounted on the wall, spatial constraints on radiation may occur between the TV and the wall surface. As a result, as the back distance between the wireless (antenna) module for communicating between the TV and the outside and the metal plate of the TV decreases (conventional: 15 mm → Slim TV: 5 mm), radiation degradation may occur. At the conventional 15 mm, the influence of the metal plate is not significant, but at a back distance of 5 mm, there is a problem that the formation of the radiation current is not smooth and less radiation can be generated. Also, as the distance between the wireless module and the concrete wall decreases (conventional: 15 mm → Slim TV: 5 mm), radiation degradation may occur. Even when using a conventional TV in a stand type or a wall-mounted TV, a space for radiation could be secured when the thickness of the TV was 50 mm or more. However, when the thickness of the TV becomes 20 mm or less, there is a problem that the distance to the wall is only 3 mm and radiation does not occur or most of the radiation electric field is absorbed by the wall.

[0034] Figure 1 illustrates an antenna module according to one embodiment of the present invention.
[0035] An antenna module 100 according to one embodiment of the present invention comprises a first radiating section 110, a second radiating section It consists of 120, a first coupling radiator 130, and a second coupling radiator 140. Then, the substrate 210, bracket 220, third radiating unit 212, and communication module chip 211 are connected. It can also include more.
[0036] The first radiating section 110 and the second radiating section 120 receive current via at least one power supply line. As a result, the frequency bands radiate signals that are different from each other.
[0037] More specifically, the first radiating portion 110 and the second radiating portion 120 are formed on the substrate 210. Current can be applied to the substrate 210 via at least one power supply line. When current is applied through the first radiating section 110 and the second radiating section 120, the applied current The flow emits a signal having a predetermined frequency band to the outside. The frequency bands of the signal being emitted and the frequency bands of the signal emitted from the second radiating unit 120 are different from each other. It can become. Regarding the specific shapes of the first radiating section 110 and the second radiating section 120, I'll explain in more detail later.
[0038] The first coupling radiating section 130 is separated from the first radiating section 110 by a predetermined distance, and the first radiating section The second coupling radiating unit 140 is coupled with the radiating unit 110 to emit a signal, and the second coupling radiating unit 140 is The second radiating unit 120 is separated from the second radiating unit 120 by a predetermined distance and coupled with the second radiating unit 120 to transmit a signal. To emit.
[0039] More specifically, the first coupling radiation unit 130 is set to a preset value with the first radiation unit 110. They are formed separated by a certain interval. The first coupling radiating portion 130 and the first radiating portion 110 are relative to each other. Since it is not connected to the power supply, the first coupling radiating section 130 does not include the power supply section, and therefore does not connect to the power supply or It may not be directly connected to the ground. The first coupling radiator 130 is insulated from other components. It can be formed by applying current to the first radiating portion 110, which separates at regular intervals. The first coupling radiator 130, which is positioned in such a way, is coupled to the first radiator 110. An electric current flows, which in turn radiates a signal. (First coupling radiator 130) The signal that is coupled and radiated is the shape of the first radiating part 110, the first coupling radiating Depending on the shape of the radiation unit 130 and the distance between the first radiation unit 110 and the first coupling radiation unit 130 It changes.
[0040] The second coupling radiating section 140 is separated from the second radiating section 120 at a predetermined distance. The second coupling radiating portion 140 and the second radiating portion 120 are not connected to each other. The second coupling radiating section 140 does not include a power supply section and is therefore not directly connected to the power supply or ground. This may not always be the case. The second coupling radiation section 140 is formed in isolation from the other components. This is possible. When current is applied to the second radiating section 120, the second radiating section, which is located at a constant distance apart, The second coupling radiating section 140 is coupled to the second radiating section 120, allowing current to flow. This results in the emission of a signal. The second coupling radiator 140 is coupled to it. The signal that is emitted is the shape of the second radiating section 120 and the shape of the second coupling radiating section 140. The shape and the distance between the second radiating portion 120 and the second coupling radiating portion 140 vary. Regarding the specific shapes of the coupling radiation portion 130 and the second coupling radiation portion 140, I'll explain that in more detail later.
[0041] For diverse communications, a single antenna module can emit multiple rays with diverse frequency bands. A projectile can be formed. In particular, for short-range communication, Wi-Fi, Bluetooth OTH (registered trademark), GPS, and NFC radiators may be required. For smart TVs, Wi-Fi and Bluetooth are used for data transmission between the TV and a shared device or mobile terminal. ooth (registered trademark) is required, and the antenna module in which the radiating part for the relevant communication is formed A joule is required.
[0042] Either the first radiating unit 110 or the second radiating unit 120 is a Wi-Fi radiating unit, and the other one This could be a Bluetooth® radiator, or a NFC radiator, etc. It is also radiation for communication. Here, the first radiation unit 110 is a Wi-Fi radiation unit. To obtain this, the first radiating unit 110 and the first coupling radiating unit 130 are connected via Wi-Fi. The frequency bands are either the 2.4 to 2.5 GHz band or the 5.0 to 5.2 GHz band, and the small number of such bands. It can resonate in at least one frequency band. The second radiating section 120 is Bluetooth It may be a radiation section for h(registered trademark). For this purpose, the second radiation section 120 is a second coupler The radiating unit 140 and the Bluetooth® frequency band are 2.4 to 2.5 It is possible to induce resonance in the GHz band.
[0043] An antenna module 100 according to one embodiment of the present invention, as shown in Figure 2, has a substrate 210 and An antenna according to one embodiment of the present invention may include a bracket 220 that covers the substrate 210. The Namodule 100 includes a first radiating section 110, a second radiating section 120, and a first coupling radiating section In forming the 130 and the second coupling radiating portion 140, the first radiating portion 110 and The second radiating portion 120 can be formed on the substrate 210, and the first coupling radiating portion The 130 and the second coupling radiating portion 140 can be formed on the bracket 220. On the substrate 210 on which the first radiating portion 110 and the second radiating portion 120 are formed, the first cup A bracket 220 on which a ring radiating portion 130 and a second coupling radiating portion 140 are formed. By joining them together, an antenna module 100 can be formed on the substrate 210. This may further include a communication module chip 211 or a third radiating unit 212. The communication module chip 211 is necessary for the communication that the antenna module 100 intends to perform. It may be a chip containing a processor that controls signals. The communication module chip 211 is It can perform various functions necessary for trust.
[0044] The first radiating portion 110 and the second radiating portion 120 are formed on the substrate 210, and the first coupling By forming the radiating portion 130 and the second coupling radiating portion 140 on the bracket 220 The first radiating section 110 and the first coupling radiating section 130 are spaced at a constant interval and the second radiating section 120 The second coupling radiation section 140 can be positioned at regular intervals. By forming the first coupling radiating portion 130 and the second coupling radiating portion on the bracket... By doing so, the first coupling radiation section 130 and the second coupling radiation section are connected to the first radiation section 1 It can be made so as not to come into contact with the 10 and the second radiating part 120, and is not connected to the power supply or ground. It can be formed in a way that prevents this from happening.
[0045] The first coupling radiating portion 130 and the second coupling radiating portion 140 are formed on the bracket. The first radiating section 110 and the second radiating section 120 are separated from each other, and the radiating section is connected to a power source or ground. Forming it so that it does not correspond to one implementation example, the first on the substrate that is not bracket 220 The coupling radiation section 130 and the second coupling radiation section 140 are connected to the first radiation section 110 and In other forms, the first coupling radiator 13 is formed at a distance from the radiator 120. The 0 and 2 coupling radiating sections 140 are separated from the 1st radiating section 110 and the 2nd radiating section 120. It is only natural that it can be formed in that way.
[0046] The first coupling radiating section 130 and the second coupling radiating section 140 are the first radiating section 11 Formed in the same or different direction, independently of the radiation direction of 0 or the second radiation section 120. This is possible. As mentioned above, the first coupling radiating section 130 is coupled with the first radiating section 110. The second coupling radiator 140 is coupled and emits a signal, and the second coupling radiator 120 The coupling radiators emit a signal. At this time, the first coupling radiator 130 or the second The direction in which the signal is emitted can be determined by the radiation direction of the coupling radiation section 140. ru.
[0047] The radiation direction of the first coupling radiation portion 130 is formed to be different from that of the first radiation portion 110. In this case, the signal that is coupled and radiated by the first coupling radiator 130 is the first coupling The signal is radiated from the first radiating unit 110, aligned with the radiation direction of the pulling radiating unit 130. Even if this is the case, it is possible to control the direction of the signal that is coupled and radiated by the relevant signal. This will become possible. For example, the first radiating portion 110 is formed to face the upper surface of the substrate. Therefore, even if the radiation direction is formed toward the upper surface of the substrate, the first coupling radiation portion 130 By forming it in a direction perpendicular to the upper surface direction of the substrate, the first coupling radiation portion 130 The direction of the emitted signal can be directed to a specific direction. Similarly, the second The coupling radiation portion 140 is also formed in a different direction from the first radiation portion 110, The direction of radiation of the signal emitted from the 2-coupling radiation unit 140 is directed in a specific direction. This is possible. The first coupling radiation section 130 and the second coupling radiation section 140 are located on the substrate 2 It can be formed on at least one outer surface of the bracket 220 that covers 10. Radiating section 110 and second radiating section 120 are formed on the substrate 210, and the upper surface of the substrate 210 The first coupling radiator 130 and the second coupling radiator 140 emit the ray. By forming it on at least one outer surface of the racket 220, a signal is emitted in the lateral direction. It can emit. The upper surface of the substrate 210 also emits a signal from the first radiating section 110 and the second radiating section. If only part 120 is formed, and if an obstruction or wall is located in the direction of the upper surface of the substrate 210, radiation Difficulties may arise. At this time, the first coupling radiation unit 130 radiates a signal in the lateral direction. And by forming the second coupling radiation portion 140, it may be generated in the direction of the upper surface of the substrate. This allows us to escape the constraints of radiative space.
[0048] Alternatively, the radiation method of the first coupling radiation unit 130 or the second coupling radiation unit 140 The direction can also be formed in the same direction as the first radial section 110 and the second radial section 120. When the radial direction of the coupling radial section 130 is formed to be the same as that of the first radial section 110, the first coupling radial section The signal that is coupled and emitted in the coupling radiator 130 is the signal in the first radiator 110 It can be emitted in the same manner as the signal, and the magnitude of the signal emitted in the relevant direction can be increased.
[0049] The first coupling radiating portion 130 and the second coupling radiating portion 140 are directed in one direction. It can be formed in such a way that the first radiating portion 110 and the second radiating portion 120 emit in a specific direction. It is formed to allow radiation, with wall-like obstacles positioned in the direction of radiation, and the radiation space is constrained. If this occurs, the first coupling radiation section 130 and the second coupling radiation section 140 will A direction different from the radiation direction of the first radiation unit 110 and the second radiation unit 120, a direction in which there are no constraints on the radiation space. It can be formed to face in that direction.
[0050] The following are the first radiating section 110, the second radiating section 120, the first coupling radiating section 130, and the second coupling radiating section A specific example of the shape of the plucking radiation portion 140 will be described.
[0051] The first coupling radiator 130 and the second coupling radiator 140 are each the first radiator The 110 and the second radiating unit 120 are coupled and begin to radiate a signal, but the first The coupling characteristics formed between the coupling radiation section 130 and the first radiation section 110 are shown in Figure As can be seen in 3A, the distance between the first coupling radiator 130 and the first radiator 110 (D1) is affected. Similarly, the second coupling radiation unit 140 and the second radiation unit 1 The coupling characteristics formed between 20 and the second coupling radiation portion 140 and the second radiation It is affected by the interval (D2) between parts 120.
[0052] Figure 3B is a graph showing the reflection losses related to D1 and D2. Here, the reflection loss is particularly This refers to the ratio of how much reflection occurs when an electrical signal is emitted relative to a constant radiating area. A lower radiation level means less loss of electrical signal during radiation. Therefore, on the graph Y The lower the axis value, the better the radiation characteristics. Here, the variable ranges for D1 and D2 are , 2.7 to 3.5 mm (unit: 0.1 mm). Reflection loss in the first radiating section 110 The loss is as shown in Figure 3B(A), and the reflection loss in the second radiating section 120 is as shown in Figure 3B(B). That's right.
[0053] After considering reflection losses, when the spacing between D1 and D2 is 2.7 to 2.9 mm, the first radiation Confirm that the resonance in section 110 or the second radiating section 120 is distorted and the radiation characteristics are degraded. This allows us to confirm that resonance occurs at 3.0 to 3.5 mm. The closer the radiating part is, the better the coupling characteristics become, but below a certain distance, the resonance becomes distorted. Therefore, D1 and D2 can be set to 3.0 mm, which is the minimum distance within the range where resonance is achieved. Taking error into consideration, D1 and D2 can be set to 2.9 to 3.1 mm.
[0054] The first radiating section 110 includes a radiating patch, at least one power supply section, and at least one support section. It may include the following: In the embodiment, as shown in Figures 4A and 4B, the first radiating section 110 is a radiating pack Chi 111, at least one power supply section 112, and at least one support section 113 to 11 It may include 5. It includes a radiating patch 111 that radiates a signal, and current from the substrate 210. It can be connected to the substrate 210 via the power supply unit 112 that receives the applied power. Radiation patch 1 11 is formed at a predetermined distance from the substrate 210, and is formed at a distance from the substrate 210. Includes support parts 113 to 115 for supporting the radiating patch 111. The configuration and support structure described herein may or may not be connected to the power supply line of the substrate 210. Depending on the design of the radiating section, it can be configured as a power supply section or a support section. Change is possible.
[0055] The first radiating section 110 may be a PIFA antenna. A flat inverted F antenna is a flat inverted F antenna where the F (F) is reversed. This refers to a flat plate antenna where a smaller area of square patch plate is placed on the contact surface of a flat plate. It consists of a grounding surface, a radiation patch, a power supply section, and a short-circuit section (short-circuit pin or short-circuit strip). It can be done. The PIFA antenna is powered by current so that the patch resonates with the ground surface. It acts as a radiating element, and the length, width, and height of the patch, the position of the feed line, and the position of the shorting pin are all determined by the patch's dimensions. The bandwidth, gain, resonant frequency, etc. can be determined by placement, etc. First radiating section 11 0 is not limited to PIFA antennas, but also includes helical and monopole antennas. It is natural that there are various types of antennas, such as standard antennas and SMD antennas.
[0056] The characteristics of the first radiating section 110 are the length (D401) and width (D410) of the radiating patch 111. It is affected by the distance (D409) at which the radiation patch 111 is separated from the substrate 210, but in particular This will be more affected by the length of radiation patch 111 (D401).
[0057] Figure 5 is a graph showing the reflection loss according to the length (D401) of the radiated patch 111. Therefore, the first coupling radiation section 130 and the first radiation section where resonance occurs most frequently at the resonant frequency. Derive the length of 110 radiation patches 111 and set that length as the length of radiation patch 111. This can be determined. Here, the first radiating unit 110 emits in the 2.4 to 2.5 GHz band. The length at which the coupling radiation section 130 and resonance most frequently occur is determined to be the optimal length, and the first radiation The length of the firing section 110 can be set to the specified length. The variable range is 14.6 to 17.6. By setting the length to mm (unit length: 1 mm), it is possible to confirm that the resonant frequency changes with length. Then, the length at which resonance with the first coupling radiation section 130 occurs most frequently is 17.6 mm. It can be confirmed that there is a radiating patch 11 of the first radiating section 110. The length of 1 may be 17.5 to 17.7 mm. Radiation patch 11 of the first radiation section 110 If the length of 1 is between 17.5 and 17.7 mm, the lengths of each element in Figure 4B will be as follows.
[0058] [Table 1]
[0059] The lengths in Table 1 represent the lengths in one embodiment, and the radiation pack of the first radiation section 110. The length of Chi 111 can be changed by the same proportion. Also, the shape or length of each component is It is natural that this can vary depending on the design. The second radiating section 120 has few radiating patches, and It may include another power supply unit and at least one support unit. In the embodiment, see Figures 5A and 5 As shown in B, the second radiating section 120 has at least one power supply for radiating patches 121 to 123. It may include part 124 and at least one support part 125. Radiation that emits a signal The patch consists of a first radiating patch 121 parallel to the substrate 210 and a second radiating patch perpendicular to the substrate 210. Formed by a patch 122, a substrate 210, and a third radiating patch 123 perpendicular to the first radiating patch 122. This can be done. Here, the second radiation patch 122 and the third radiation patch 123 are powered It can be said that this is a power supply patch connected to part 124 through which current flows. Radiation patches 121 to 123 are The circuit board 210 is connected to the circuit board 210 via a power supply unit 124 that receives current from the circuit board 210. This is possible. The power supply unit 124 and the radiation patch 121 are connected via the radiation patch 122. Thus, the radiation patch 121 is formed at a predetermined distance from the substrate 210, and It can be supported by injection patches 122, 123 and support part 125. The configuration described and the configuration described as a support part are connected to the power supply line of the substrate 210. Depending on whether or not it is present, it can be configured as a power supply unit or a support unit. Also, the radiation patch, It can be formed in a variety of shapes, and can be changed by the design of the radial section.
[0060] The second radiating section 120 can also be a PIFA antenna. Not limited to FA antennas, but also helical and monopole antennas, S It is only natural that a variety of antennas, such as MD antennas, should be available.
[0061] The characteristics of the second radiation unit 120 are the length (D601), width (D605) of the radiation patch, and substrate 2 It is affected by the distance (D602) at which the radiated patch separates from 10, but in particular, the radiated patch The length (D601) will have a greater influence.
[0062] Figure 7 is a graph showing the reflection loss according to the length of the radiated patch (D601), which means , the second coupling radiating section 140 and the second radiating section 120 at the resonant frequency where resonance occurs most frequently The length of the radiation patch can be derived, and that length can be set as the length of the radiation patch. Here, the second radiating section 120 is in the 2.4 to 2.5 GHz band and the second coupling radiating section 1 The length at which resonance with 40 occurs most frequently is determined to be the optimal length, and the length of the second radiating section 120 is set accordingly. This length can be set to 15.3 to 18.3 mm (unit length: 1 m). As m), we can confirm that the resonant frequency changes with length, and the second coupling The length at which resonance most frequently occurs with the radiating portion 140 is 17.3 mm (Length=2). It can be confirmed that this is the case. Taking the error into account, the length of the radiation patch of the second radiation section 120 The size can be between 17.2 and 17.4 mm.
[0063] When the length of the radiation patch of the second radiation section 120 is 17.2 to 17.4 mm, Figure 6B The lengths of each are as follows:
[0064] [Table 2]
[0065] The lengths and angles in Table 2 represent the lengths and angles in one embodiment, and the second radiation The length of the radiation patch of section 120 can be changed by the same proportion. Also, the shape of each configuration The shape and length can naturally vary depending on the design. First coupling radiating section 1 30 can be formed by line patch 131 as shown in Figure 8. First coupling The radial portion 130 is formed by line-shaped line patches 131 and the first radial portion 110 and They can be coupled and resonate. At this time, the first coupling radiation section 130 The line patch 131 can be formed in the meander line shape. Here, The Meander line shape is a curved or winding shape, as shown in Figure 8. It refers to a specific shape and can also be described as a zigzag shape. To form the line, line patches 131 can be formed in a meander line shape. This allows for the formation of a small antenna module. Figure 9 shows the first coupler. This shows the reflection loss of the first radiating section 110 in proportion to the total length of the line patch 131 of the radiating section 130. This graph shows that the first radiation section 110 and the first resonant frequency at which resonance occurs most frequently are the first radiating section 110. The length of the line patch 131 of the plucking radiation section 110 is determined, and the corresponding length is used for the line patch The length of the ch 131 can be set. Here, the first coupling radiation section 130 is The optimal length for the first radiating element 110 to resonate most frequently in the 2.4 to 2.5 GHz band. Based on this determination, the length of the line patch 131 of the first coupling radiation section 130 is set to the appropriate length. It can be set. Set the variable range to 31.4 to 35.4 mm (unit length: 1 mm). By doing so, it was possible to confirm that the resonant frequency changes according to the length, and together with the first radiating section 110 Confirm that the length at which vibration most frequently occurs is 31.4 mm (Length=1). It is possible. Taking the error into consideration, the length of the line patch of the first coupling radiation section 130 is It can be 31.3 to 31.5 mm.
[0066] The second coupling radiation section 140 includes a square patch and at least one line patch. This can be achieved, and as shown in Figure 8, it is formed by square patch 141, line patches 142, and 143. It can be done. The square patch 141 is formed in a square shape, and the first line patch 14 Line 2 extends from one end of square patch 141, and line patch 143 extends from square patch 14 It can be formed extending from the other end of 1. First line patch 142 or second line At least one line patch of patch 143 is formed in the shape of a meander line. It is possible.
[0067] Figure 10 shows the second line patch 143 of the second coupling radiation section 140, corresponding to the total length of the second line patch 143. This graph shows the reflection loss of the second radiating section 120, which indicates the resonant frequency of the second radiating section 120. The length of the line patch of the second coupling radiation section 140, where resonance occurs most frequently, is determined. Then, the corresponding length can be set as the length of the line patch. Here, the second coupling The radiating section 140 resonates most frequently with the second radiating section 120 in the 2.4 to 2.5 GHz band. The length is determined to be the optimal length, and the second line patch 14 of the second coupling radiation section 14 The length of 3 can be set to the corresponding length. Here, the square patch 141 is 21.7m Formed with a length of m and a width of 5 mm, the length of the first line patch 142 is 24.35 m. m, and the variable range of the length of the second line patch 143 is 17.85 to 35.85 mm. By setting the unit length to 2mm, it was possible to confirm that the resonant frequency changes depending on the length. We confirmed that the length at which resonance with the second radiating section 120 occurs most frequently is 18.85 mm. It is possible to take the error into consideration, the square patch 141 of the second coupling radiation section 140 It is formed with a length of 21.6 to 21.8 mm and a width of 4.9 to 5.1 mm, and the first The length of line patch 142 is 24.25 to 24.45 mm, and the second line patch 143 The length can be between 18.75 and 18.95 mm.
[0068] The length of the line patch 131 of the first coupling radiation section 130 is 31.3 to 31.5 In mm, the square patch 141 of the second coupling radiation section 140 is 21.6 to 21.8 m Formed with a length of m and a width of 4.9 to 5.1 mm, the length of the first line patch 142 is , 24.25 to 24.45 mm, the length of the second line patch 143 is 18.75 to When the length is 18.95 mm, the lengths in Figure 8 are as follows:
[0069] [Table 3]
[0070] The lengths in Table 3 represent the lengths in one embodiment, specifically for the first coupling radiation section. Length of line patch 131 of 130 or second line patch 1 of second coupling radiation 43 can change in the same proportion depending on the length. Also, the shape or length of each component is It is natural that it can change depending on the design. The first coupling radiation section 130 or the second coupling The coupling radiation section 140 has a degree of isolation (isolation) from each other. It can be formed with a length such that (on) is less than or equal to a threshold. First coupling radiation section 1 30 is coupled with the first radiating section 110, and the second coupling radiating section 140 is the second It is coupled with the radiating part 120, but both coupling radiating parts are coupled If they are involved, they can influence each other. Therefore, they should be different from each other so as not to influence each other. It can be formed with a length such that the coupling radiation portion and the degree of isolation are below a threshold. The isolation degree represents the influence between the two radiators, and the signal emitted from one radiator is This refers to the ratio of radiation entering other radiating regions; a lower value indicates higher radiation characteristics. Figure 11 is a graph showing the isolation diagram, and as described above, the first coupling radiation section 130 The length of the inpatch 131 is 31.3 to 31.5 mm, and the second coupling radiation portion 14 Square patch 141 of type 0 has a length of 21.6 to 21.8 mm and a width of 4.9 to 5.1 mm. Formed with a width of 142, the length of the first line patch 142 is 24.25 to 24.45 mm. The isolation level is low when the length of the second line patch 143 is between 18.75 and 18.95 mm. This can be understood.

The first radiating unit 110 is for Wi-Fi. When it is a radiating unit, in order to improve the radiation characteristics of the Wi-Fi signal, the third radiating unit 212 is further It can include. The number and shape of the radiating parts formed on the antenna module 100 are... It can be changed through modular design.
[0072] An antenna module 100 according to an embodiment of the present invention is transmitted via at least one feed line It may include a third radiating section 212 to which current is applied, and the third radiating section 212 is the first radiating section It can be formed at a predetermined distance from 110.

As shown in Figure 2, the substrate 210 In addition to the first and second radiating sections 110 and 120, a third radiating section 212 can be formed above. At this time, the third radiating unit 212 is a Wi-Fi radiating unit, just like the first radiating unit 110. To obtain, when forming the third radiating portion 212, separate it from the first radiating portion 110 at a predetermined distance. It can be formed in such a way that, in order to reduce interference between radiating parts, the longitudinal direction of the radiating patch is They can be formed in ways that are different from one another.

Therefore, due to the low back distance, the influence of the bottom metal plate 1510 is significant, resulting in better radiation. It can be seen that this does not hold true. In contrast, Figure 13B shows the first coupling antenna. And the current flow measured at 2.4 GHz when including the second coupling antenna Compared to Figure 13A, the side view, i.e., the region 1310 where the coupling antenna is formed, It can be seen that an electric current is formed. That is, a coupling antenna is used to form a coupling By causing the radiated current to be discharged to the coupling antenna, the entire surface of the coupling antenna ( It can be confirmed that radiation occurs smoothly in the space between the metal plate and the wall. Cut.
[0078] Figure 14A shows the current flow measured at 5 GHz without a coupling antenna. As a result of the influence of wall surface 1520, many Null points are generated in the radiation pattern and radiation It can be seen that this is not done often. In contrast, Figure 14B shows the first coupling agent The current flow measured at 5 GHz, including the tenor and second coupling antenna, is shown in Figure Compared to 14A, the current in the side, i.e., region 1410 where the coupling antenna is formed, It can be seen that a flow is formed.
