The signal coupled to and radiated by the second coupling radiation part 140 varies according to the shape of the second radiation part 120, the shape of the second coupling radiation part 140, and the distance between the second radiation part 120 and the second coupling radiation part 140. The specific shapes of the first coupling radiation part 130 and the second coupling radiation part 140 will be described in detail later.

[0043] As shown in FIG. 2, the antenna module 100 according to an embodiment of the present invention may include a substrate 210 and a bracket 220 covering the substrate 210. The antenna module 100 according to an embodiment of the present invention includes a first radiation unit 110, a second radiation unit 120, a first coupling radiation unit 130, and a second coupling radiation unit 140. When forming the first radiation unit 110 and the second radiation unit 120, the first radiation unit 110 and the second radiation unit 120 can be formed on the substrate 210, and the first coupling radiation unit 130 and the second coupling radiation unit 140 can be formed on the bracket 220. The antenna module 100 can be formed by coupling the bracket 220 on which the first coupling radiation unit 130 and the second coupling radiation unit 140 are formed to the substrate 210 on which the first radiation unit 110 and the second radiation unit 120 are formed. The substrate 210 may further include a communication module chip 211 or a third radiation unit 212. The communication module chip 211 may be a chip including a processor that controls signals necessary for communication to be performed by the antenna module 100. The communication module chip 211 can perform various functions necessary for communication.

[0044] By forming the first radiation unit 110 and the second radiation unit 120 on the substrate 210 and forming the first coupling radiation unit 130 and the second coupling radiation unit 140 on the bracket 220, the first radiation unit 110 and the first coupling radiation unit 130 are spaced apart by a certain distance and the second radiation unit 120 and the second coupling radiation unit 140 are spaced apart by a certain distance, and the first radiation unit 110, the first coupling radiation unit 130, the second radiation unit 120, and the second coupling radiation unit 140 are arranged in a specific order. and the second coupling radiation part 140 can be positioned at a certain interval and separated from each other. Also , by forming the first coupling radiation part 130 and the second coupling radiation part on the bracket , the first coupling radiation part 130 and the second coupling radiation part can be made not to contact the first radiation part 1 10 and the second radiation part 120, and can be formed so as not to be connected to a power source or a ground .

[0045] Forming the first coupling radiation part 130 and the second coupling radiation part 140 on the bracket so as to be separated from the first radiation part 110 and the second radiation part 120 or not to be connected to a power source or a ground corresponds to one implementation example. Similar to forming the first coupling radiation part 130 and the second coupling radiation part 140 on a substrate other than the bracket 220 so as to be separated from the first radiation part 110 and the second radiation part 120 , it is natural that the first coupling radiation part 130 and the second coupling radiation part 140 can be formed in other forms so as to be separated from the first radiation part 110 and the second radiation part 120. 2 radiation part 120. 0 and the second coupling radiation part 140 are separated from the first radiation part 110 and the second radiation part 120 .

[0046] The first coupling radiation part 130 and the second coupling radiation part 140 can be formed in the same direction or different directions independently of the radiation direction of the first radiation part 11 0 or the second radiation part 120. As described above, the first coupling radiation part 130 is coupled with the first radiation part 110 to radiate a signal, and the second coupling radiation part 140 is coupled with the second radiation part 120 to radiate a signal. At this time, the direction in which the signal is radiated can be formed by the radiation direction of the first coupling radiation part 130 or the second coupling radiation part 140. coupling radiation part 140. coupling radiation part 140 is coupled with the second radiation part 120 to radiate a signal. At this time, the direction in which the signal is radiated can be formed by the radiation direction of the first coupling radiation part 130 or the second coupling radiation part 140.

[0047] ​Form the radiation direction of the first coupling radiation unit 130 to be different from that of the first radiation unit 110. In this case, the signal coupled and radiated by the first coupling radiation unit 130 will be along the radiation direction of the first coupling radiation unit 130. Even if a signal is radiated from the first radiation unit 110, it becomes possible to control the direction of the signal coupled and radiated by the corresponding signal. For example, if the first radiation unit 110 is formed to face the upper surface of the substrate, even if the radiation direction is formed in the direction of the upper surface of the substrate, by forming the first coupling radiation unit 130 in a direction perpendicular to the upper surface direction of the substrate, the direction of the signal radiated from the first coupling radiation unit 130 can be directed to the corresponding specific direction. Similarly, by forming the second coupling radiation unit 140 in a direction different from that of the first radiation unit 110, the radiation direction of the signal radiated from the second coupling radiation unit 140 can be directed to a specific direction. The first coupling radiation unit 130 and the second coupling radiation unit 140 can be formed on at least one outer surface of the bracket 220 covering the substrate 210. When the first radiation unit 110 and the second radiation unit 120 are formed on the substrate 210 and the first coupling radiation unit 130 and the second coupling radiation unit 140 are formed on at least one outer surface of the bracket 220 to radiate a signal to the upper surface of the substrate 210, signals can be radiated in the side direction. If only the first radiation unit 110 and the second radiation unit 120 that also radiate signals are formed on the upper surface of the substrate 210 and there are obstacles or walls in the upper surface direction of the substrate 210, difficulties may occur in radiation. At this time, by forming the first coupling radiation unit 130 and the second coupling radiation unit 140 that radiate signals in the side direction, it is possible to avoid difficulties that may occur in the upper surface direction of the substrate. The first coupling radiation unit 130 and the second coupling radiation unit 140 can be formed on at least one outer surface of the bracket 220 covering the substrate 210. By forming the first radiation unit 110 and the second radiation unit 120 on the substrate 210 to radiate signals to the upper surface of the substrate 210, and forming the first coupling radiation unit 130 and the second coupling radiation unit 140 on at least one outer surface of the bracket 220, signals can be radiated in the side direction. If only the first radiation unit 110 and the second radiation unit 120 that radiate signals are formed on the upper surface of the substrate 210, and there are obstacles or walls in the upper surface direction of the substrate 210, radiation difficulties may occur. In this case, by forming the first coupling radiation unit 130 and the second coupling radiation unit 140 that radiate signals in the side direction, it is possible to avoid difficulties that may occur in the upper surface direction of the substrate. The radiation of signals in the side direction can be achieved. When only the first radiation unit 110 and the second radiation unit 120 that radiate signals are formed on the upper surface of the substrate 210, and there are obstacles or walls in the upper surface direction of the substrate 210, radiation difficulties may occur. At this time, by forming the first coupling radiation unit 130 and the second coupling radiation unit 140 that radiate signals in the side direction, it is possible to avoid difficulties that may occur in the upper surface direction of the substrate. If only the first radiation unit 110 and the second radiation unit 120 that radiate signals are formed on the upper surface of the substrate 210, and there are obstacles or walls in the upper surface direction of the substrate 210, radiation difficulties may occur. At this time, by forming the first coupling radiation unit 130 and the second coupling radiation unit 140 that radiate signals in the side direction, it is possible to avoid difficulties that may occur in the upper surface direction of the substrate. 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 shown in FIG. 3A, the distance between the first coupling radiation part 130 and the first radiation part 110 is affected by (D1). Similarly, the coupling characteristics formed between the second coupling radiation part 140 and the second radiation part 120 are affected by the distance (D2) between the second coupling radiation part 140 and the second radiation part 120.

[0052] FIG. 3B is a graph showing the reflection loss related to D1 and D2. Here, the reflection loss means the ratio of how much reflection occurs when an electrical signal radiates based on a specific radiation part, and the less reflection, the less loss of the electrical signal and the more radiation. Therefore, the lower the Y-axis value on the graph, the better the radiation characteristics. Here, the variable ranges of D1 and D2 are from 2.7 to 3.5 mm (unit: 0.1 mm). The reflection loss in the first radiation part 110 is as shown in (A) of FIG. 3B, and the reflection loss in the second radiation part 120 is as shown in (B) of FIG. 3B. As a result of considering the reflection loss, when the distances of D1 and D2 are from 2.7 to 2.9 mm, it can be confirmed that the resonance in the first radiation part 110 or the second radiation part 120 is distorted and the radiation characteristics are deteriorated, and it can be confirmed that resonance occurs at 3.0 to 3.5 mm. The closer the distances of the two radiation parts are, the better the coupling characteristics, but if the distance is below a certain value, the resonance is distorted.

[0053] Therefore, D1 and D2 can be set to 3.0 mm, which is the minimum distance within the range where resonance occurs. Considering the error, D1 and D2 can be set to 2.9 to 3.1 mm.

[0054] The first radiation part 110 includes a radiation patch, at least one feeding part, and at least one supporting part. It can include. In an embodiment, as shown in FIGS. 4A and 4B, the first radiation unit 110 includes a radiation patch 111, at least one feeding unit 112, and at least one supporting unit 113 to 11 5. It can include a radiation patch 111 that radiates a signal and can be connected to the substrate 210 through a feeding unit 112 that receives an applied current from the substrate 210. The radiation patch 1 11 is formed at a predetermined interval from the substrate 210 and includes supporting units 113 to 115 for supporting the radiation patch 111 formed separately from the substrate 210. The configuration described as the feeding unit and the configuration described as the supporting unit can be configured as a feeding unit or a supporting unit depending on whether it is connected to the feeding line of the substrate 210.
