The rear distance between the module and the TV's metal plate has been reduced. As the thickness increases (conventional: 15 mm → Slim TV: 5 mm), radiation degradation may occur. At 5mm, the metal plate effect is not large, but at a back distance of 5mm, the radiation current formation The problem is that it is not smooth and radiation is poor. Also, the wireless module and concrete As the distance between the wall and the TV is reduced (conventional: 15mm → Slim TV: 5mm), the radiation Deterioration may occur. When using a conventional TV on a stand or a wall-mounted TV, However, when the TV was 50mm or thicker, the space for radiation was secured, but when the TV was 20mm thick, If the distance to the wall is less than 3mm, no radiation occurs or most of the radiation There is a problem that the electric field is absorbed by the wall.

In particular, for short-distance communication, Wi-Fi, Bluetooth For smart TVs, you may need a radiator for Bluetooth, GPS, and NFC. Wi-Fi and Bluetooth are used to send and receive data between the TV and a sharing device or mobile device. oth (registered trademark) is required, and the antenna module that forms the radiating part for the corresponding communication A rule is required.

[0042] Either the first radiating portion 110 or the second radiating portion 120 is a radiating portion for Wi-Fi, and the other It may be a Bluetooth® radiator, or another radiator such as an NFC radiator. Here, the first radiating portion 110 is a radiating portion for Wi-Fi. For this purpose, the first radiating unit 110 is connected to the first coupling radiating unit 130 via a Wi-Fi A small number of frequencies in the 2.4 to 2.5 GHz band or the 5.0 to 5.2 GHz band The second radiating portion 120 can resonate in at least one band. For this purpose, the second radiating portion 120 may be a radiating portion for the second coupling The radiating portion 140 and the Bluetooth® frequency band 2.4 to 2.5 Resonance can occur in the GHz band.

[0043] As shown in FIG. 2, the antenna module 100 according to the embodiment of the present invention includes a substrate 210 and a The antenna according to an embodiment of the present invention may include a bracket 220 that covers the substrate 210. The module 100 includes a first radiating section 110, a second radiating section 120, a first coupling radiating section 130 and the second coupling radiation section 140 are formed by using the first radiation section 110 and The second radiating portion 120 may be formed on the substrate 210, and the first coupling radiating portion The first coupling radiating portion 130 and the second coupling radiating portion 140 can be formed on the bracket 220. The first cup is placed on the substrate 210 on which the first radiating portion 110 and the second radiating portion 120 are formed. The bracket 220 on which the ring radiating portion 130 and the second coupling radiating portion 140 are formed is By combining the elements, the antenna module 100 can be formed. may further include a communication module chip 211 or a third radiating part 212. The communication module chip 211 is a chip necessary for communication to be performed by the antenna module 100. The communication module chip 211 may be a chip that includes a processor that controls the communication signal. 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 radiation part 130 and the second coupling radiation part 140 on the bracket 220, The first radiating section 110 and the first coupling radiating section 130 are spaced apart by a certain distance, and the second radiating section 120 The second coupling radiation part 140 may be spaced apart at regular intervals. The bracket is provided with a first coupling radiation portion 130 and a second coupling radiation portion. As a result, the first coupling radiating section 130 and the second coupling radiating section are connected to the first radiating section 1 The second radiation part 10 and the second radiation part 120 can be prevented from contacting each other and can be connected to a power source or a ground. It can be formed so that it is not

[0045] The first coupling radiation part 130 and the second coupling radiation part 140 are formed on the bracket. The first radiation part 110 and the second radiation part 120 are spaced apart from each other and are connected to a power source or a ground. In one embodiment, the bracket 220 is not formed on the substrate. The coupling radiating section 130 and the second coupling radiating section 140 are connected to the first radiating section 110 and Similarly to forming the first coupling radiation portion 13 apart from the second radiation portion 120, 0 and the second coupling radiation part 140 are spaced apart from the first radiation part 110 and the second radiation part 120. It goes without saying that it can be formed in this way.

[0046] The first coupling radiating section 130 and the second coupling radiating section 140 are 10 or the second radiating portion 120. As described above, the first coupling radiation portion 130 is coupled to the first radiation portion 110. The second coupling radiating section 140 radiates a signal by coupling with the second radiating section 120. At this time, the first coupling radiation unit 130 or the second coupling radiation unit 131 couples the signal. The radiation direction of the coupling radiation portion 140 can determine the direction in which the signal is radiated. do.

[0047] The radiation direction of the first coupling radiation part 130 is formed to be different from that of the first radiation part 110. In this case, the signal coupled and radiated by the first coupling radiating section 130 is The first radiating portion 110 radiates a signal in the direction of the radiation of the first radiating portion 130. Even if a signal is coupled to the target, the direction of the radiated signal can be controlled. For example, the first radiating portion 110 may be formed to face the upper surface of the substrate. As a result, even if the radiation direction is formed in the direction of the upper surface of the substrate, the first coupling radiation portion 130 By forming it in a direction perpendicular to the upper surface of the substrate, The direction of the signal emitted from the second antenna can be directed in a specific direction. The coupling radiating portion 140 is also formed in a direction different from that of the first radiating portion 110, 2. Directing the radiation direction of the signal radiated from the coupling radiation unit 140 in a specific direction The first coupling radiating portion 130 and the second coupling radiating portion 140 are formed on the substrate 2. 10 may be formed on at least one outer surface of the bracket 220. The radiating portion 110 and the second radiating portion 120 are formed on the substrate 210. The first coupling radiating section 130 and the second coupling radiating section 140 radiate the beam. By forming a signal on at least one outer surface of the racket 220, a signal can be emitted in a lateral direction. The top surface of the substrate 210 also has a first radiating portion 110 and a second radiating portion 112 that radiate signals. When only the portion 120 is formed, if an obstacle or a wall is located on the upper surface of the substrate 210, the radiation In this case, the first coupling radiation part 130 that radiates a signal in the lateral direction may have difficulty. By forming the second coupling radiation portion 140, the radiation that can be generated in the direction of the upper surface of the substrate can be This allows us to escape the radiation space constraints.

[0048] Alternatively, the radiation direction of the first coupling radiation unit 130 or the second coupling radiation unit 140 may be The direction of the first radiating portion 110 and the second radiating portion 120 may be the same as that of the first radiating portion 110 and the second radiating portion 120. When the radiation direction of the coupling radiation part 130 is formed to be the same as that of the first radiation part 110, The signal coupled and radiated by the coupling radiator 130 is converted into a signal by the first radiator 110. and the magnitude of the signal radiated in the corresponding direction can be increased.

[0049] The first coupling radiation portion 130 and the second coupling radiation portion 140 are oriented in one direction. The first radiating part 110 and the second radiating part 120 can be formed as follows. The radiation space is restricted by obstacles such as walls in the radiation direction. If this occurs, the first coupling radiation unit 130 and the second coupling radiation unit 140 A direction in which there are no restrictions on the radiation space, which is different from the radiation direction of the first radiation unit 110 and the second radiation unit 120. The optical fiber 10 can be configured to be oriented toward the optical fiber 10.

[0050] Hereinafter, the first radiating section 110, the second radiating section 120, the first coupling radiating section 130, the second coupling radiating section 140, the A specific embodiment of the shape of the coupling radiator 140 will now be described.

[0051] The first coupling radiating section 130 and the second coupling radiating section 140 are The first radiator 110 and the second radiator 120 are coupled to radiate a signal. The coupling characteristics formed between the coupling radiating portion 130 and the first radiating portion 110 are shown in FIG. As can be seen in FIG. 3A, the distance between the first coupling radiating portion 130 and the first radiating portion 110 is Similarly, the second coupling radiating section 140 and the second radiating section 1 The coupling characteristics formed between the second coupling radiating portion 140 and the second radiating portion 20 are This is affected by the distance (D2) between the sections 120.

[0052] FIG. 3B is a graph showing the return loss for D1 and D2. It means the ratio of how much reflection occurs when an electrical signal is emitted based on a constant radiating point. The lower the radiation, the less the loss of the electrical signal. The lower the axis value, the better the radiation characteristics. Here, the variable range of D1 and D2 is , 2.7 to 3.5 mm (unit: 0.1 mm). The reflection loss at the second radiating portion 120 is as shown in FIG. 3B(A), and the reflection loss at the second radiating portion 120 is as shown in FIG. 3B(B). That's right.

[0053] Considering the reflection loss, when the distance between D1 and D2 is 2.7 to 2.9 mm, the first radiation It is confirmed that the resonance in the first radiating portion 110 or the second radiating portion 120 is distorted and the radiation characteristics are deteriorated. It can be confirmed that resonance occurs at 3.0 to 3.5 mm. The closer the distance between the radiating parts, the better the coupling characteristics, 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 resonance range. Taking into account the tolerance, D1 and D2 can be set to 2.9 to 3.1 mm.

The structure described as the support portion may or may not be connected to the power supply line of the substrate 210. This can be configured as a feed or support depending on the radiator design. You can change.

This means a flat antenna with a square patch plate of smaller area mounted on the ground plane of a flat plate like the one shown above. It consists of a ground plane, a radiating patch, a feed point, and a shorting point (short-circuit pin or short-circuit strip). The PIFA antenna is designed so that the patch does not resonate with the ground plane due to the current supply. It acts as a radiating element, and the length, width, height, position of the feed line and the position of the shorting pin of the patch are The bandwidth, gain, resonant frequency, etc. can be determined by the placement of the first radiating portion 11. 0 is not limited to PIFA antennas, but also includes helical and monopole antennas. Of course, various antennas such as a ferroelectric antenna, an SMD antenna, etc. may also be used.

[0056] The characteristics of the first radiating section 110 are the length (D401) and width (D410) of the radiating patch 111, The distance (D409) between the substrate 210 and the radiation patch 111 is affected, but in particular , it is greatly affected by the length (D401) of the radiation patch 111.

[0057] FIG. 5 is a graph showing the return loss as a function of the length (D401) of the radiation patch 111. As a result, the first coupling radiating portion 130 and the first radiating portion 140 which most frequently resonate at the resonant frequency The length of the radiation patch 111 of 110 is calculated and set to the length of the radiation patch 111. Here, the first radiating portion 110 can be set to a first The length at which resonance with the coupling radiating portion 130 occurs most frequently is determined as the optimum length, and the first radiating portion is The length of the projection 110 can be set to the corresponding length. The variable range is 14.6 to 17.6. mm (unit length: 1 mm), it is possible to confirm that the resonance frequency changes depending on the length. Therefore, the length at which resonance with the first coupling radiating portion 130 occurs most frequently is 17.6 mm. It can be confirmed that the radiating patch 11 of the first radiating section 110 is The length of the radiating patch 11 of the first radiating section 110 may be 17.5 to 17.7 mm. If the length of 1 is 17.5 to 17.7 mm, the lengths in FIG. 4B are as follows:

The patches are a first radiation patch 121 parallel to the substrate 210 and a second radiation patch perpendicular to the substrate 210. The third radiating patch 123 is perpendicular to the first radiating patch 122, the substrate 210, and the third radiating patch 123. Here, the second radiating patch 122 and the third radiating patch 123 can be fed The radiating patches 121 to 123 are connected to the section 124 and can be said to be feeding patches through which current flows. , and is connected to the substrate 210 via a power supply part 124 that receives current from the substrate 210. The power supply section 124 and the radiation patch 121 are connected via the radiation patch 122. The radiation patch 121 is formed at a predetermined distance from the substrate 210.

The first coupling radiation portion 1 can be formed to have a length such that the first coupling radiation portion 1 is equal to or less than a threshold value. 30 is coupled to the first radiating section 110, and the second coupling radiating section 140 is coupled to the second The radiating section 120 is coupled to the radiating section 120, but both the radiating sections are coupled. Therefore, they must be designed to be different from each other so that they do not affect each other. The coupling radiation portion can be formed to have a length such that the degree of isolation from the coupling radiation portion is equal to or less than a threshold value. The isolation represents the influence between two radiators, and the signal radiated from one radiator is This means the ratio of radiation entering other radiation parts, and the lower this is, the better the radiation characteristics are. FIG. 11 is a graph showing the isolation diagram, and as described above, the first coupling radiating section 130 The length of the in-patch 131 is 31.3 to 31.5 mm, and the second coupling radiation section 14 The square patch 141 of 0 has a length of 21.6 to 21.8 mm and a width of 4.9 to 5.1 mm.
