The base 100 has a first end 101 and a second end 102 opposite to each other. The base 100 is generally in the shape of a long strip. The distance between the first end 101 and the second end 102 relative to each other is the length of the long side of the base 100 . The elongated substrate 100 arranges the first main antenna 1, the second main antenna 2 and the auxiliary antenna 3 in a row. This antenna module is used to be installed in the casing space above the screen of a notebook computer as a built-in antenna module. The casing space above the screen of the above-mentioned notebook computer is a commonly used location for placing built-in antenna modules. Some parts of the strip-like structure in the picture have incisions (dents), or the section of the strip is slightly similar to a trapezoid. This makes it easier to assemble the antenna module and the internal structure of the laptop more closely, making it more suitable for practical applications. The model does not affect the main characteristics of the antenna module.

Referring to FIG. 3 , a rear view shows the antenna configuration on the back side 100 b of the substrate 100 . Referring to FIG. 4 , a top view shows the antenna configuration on the upper surface 100 c of the substrate 100 . Refer to Figure 5, looking down The angle shows the antenna configuration of the bottom surface 100d of the substrate 100. The first main antenna 1 is disposed on the base 100 and close to the first end 101, and has a first radiating part 11 and a second radiating part 12.

The second radiation part 12 has a first ground terminal 12a, wherein the first feed terminal 11a is not in contact with the first feed line F1 and forms a coupled feed, and the first ground terminal 12a is connected to the ground G. Figures 6A, 6B, and 6C show the configuration of feeders and copper foil. The feeders include three, namely a first feeder F1, a second feeder F2, and a third feeder F3. The copper foil is mainly divided into two large areas, namely the first copper foil C1 and the second copper foil C2, which are used to ground the antenna module. The first copper foil C1 is below the first main antenna 1 and on The bottom surface 100d is connected to the base 100. The second copper foil C2 is below the second main antenna 2 and the auxiliary antenna 3 and is connected to the base 100 on the bottom surface 100d. In the figure, the copper foil located under each antenna represents the ground G. The ground connection method will not be described again in the following. Referring again to the bottom perspective view of FIG. 5 and the perspective view of FIG. 6B, since the above-mentioned first feed line F1 is provided on the bottom surface 100d of the base 100, the first feed end 11a extends to the bottom surface 100d of the base 100 to connect with the bottom surface 100d. The first feeder F1 achieves the best coupling.

The first branch 111 and the second branch 112 are respectively connected to the first feed end 11 a. The first branch 111 and the second branch 112 extend in opposite directions to each other. In the figure, most of the first radiating part 11 is located on the front surface 100 a , the first branch 111 extends toward the direction close to the auxiliary antenna 3 , and the second branch 112 extends toward the direction away from the auxiliary antenna 3 . The second branch 112 includes a U-shaped bend, which reverses the path of the second branch 112 so that the end of the second branch 112 is close to the first branch 111 and is coupled with the first branch 111 to stimulate more operating modes.

所述第二輻射部12耦合所述第一輻射部11，第二輻 射部12有一大部分是位於背面100b。第一輻射部11位於第二輻射部12的第一接地端12a與輔助天線3之間。第二輻射部12具有主段121、彎折段122與延伸末段123，在背面100b的主段121連接第一接地端12a，在上面100c的彎折段122連接主段121，在正面100a的延伸末段123連接彎折段122。延伸末段123位於第一輻射部11與輔助天線3之間，用以提高第一主天線1與輔助天線3兩者之間的隔離度。在圖中，延伸末段123並非靠近輔助天線3，而是更靠近於第一輻射部11的第一分支111，以幫助第二輻射部12耦合第一輻射部11。 The second radiating part 12 is coupled to the first radiating part 11, and the second radiating part 12 is A large part of the radiating part 12 is located on the back surface 100b. The first radiating part 11 is located between the first ground terminal 12 a of the second radiating part 12 and the auxiliary antenna 3 .

The bent section 122 on the upper surface 100c is connected to the main section 121. On the front 100a The extended end section 123 is connected to the bent section 122 . The extended end section 123 is located between the first radiating part 11 and the auxiliary antenna 3 to improve the isolation between the first main antenna 1 and the auxiliary antenna 3 . In the figure, the extended end section 123 is not close to the auxiliary antenna 3 but closer to the first branch 111 of the first radiating part 11 to help the second radiating part 12 couple with the first radiating part 11 .

第二主天線2設置於所述基底100，且靠近於所述第二端102，具有第三輻射部21與第四輻射部22，所述第三輻射部21具有第二饋入端21a，所述第四輻射部22具有第二接地端22a，其中所述第二饋入端21a與第二饋線F2不接觸且構成耦合饋入，所述第二接地端22a連接所述接地G。參照圖5的下視角與圖6B的立體圖，由於上述的第二饋線F2是設置在基底100的底面100d，第二饋入端21a延伸到基底100的底面100d，以與位於底面100d的第二饋線F2達到最佳的耦合。 The second main antenna 2 is disposed on the base 100 and close to the second end 102, and has a third radiating part 21 and a fourth radiating part 22. The third radiating part 21 has a second feed end 21a, The fourth radiation part 22 has a second ground terminal 22a, wherein the second feed terminal 21a is not in contact with the second feed line F2 and forms a coupled feed, and the second ground terminal 22a is connected to the ground G. Referring to the bottom perspective view of FIG. 5 and the perspective view of FIG. 6B , since the above-mentioned second feed line F2 is provided on the bottom surface 100d of the base 100, the second feed end 21a extends to the bottom surface 100d of the base 100 to connect with the second feed line F2 located on the bottom surface 100d. Feeder F2 achieves optimal coupling.

再者，一併參照圖8的局部放大圖，第四輻射部22更包括第三接地端22b，第三接地端22b連接接地G，第二接地端22a與第三接地端22b彼此平行。所述第四輻射部22耦合所述第三輻射部21。進一步，第四輻射部22的第二接地端22a位於第三輻射部21與輔助天線3之間。再者，第三輻射部21比第四輻射部22更靠近接地G，第三輻射部21與第四輻射部22彼此以相反方向延伸。 Furthermore, referring to the partial enlarged view of FIG. 8 , the fourth radiating part 22 further includes a third ground terminal 22b. The third ground terminal 22b is connected to the ground G. The second ground terminal 22a and the third ground terminal 22b are parallel to each other. The fourth radiating part 22 is coupled to the third radiating part 21 . Furthermore, the second ground end 22 a of the fourth radiating part 22 is located between the third radiating part 21 and the auxiliary antenna 3 . Furthermore, the third radiating part 21 is closer to the ground G than the fourth radiating part 22 , and the third radiating part 21 and the fourth radiating part 22 extend in opposite directions to each other.

輔助天線3設置於所述基底100，且位於所述第一主 天線1與所述第二主天線2之間，具有第三饋入端3a，所述第三饋入端3a與第三饋線F3不接觸且構成耦合饋入。第一饋入端11a構成的耦合饋入與第三饋入端構3a成的耦合饋入用以提高第一主天線1與輔助天線3兩者之間的隔離度。 The auxiliary antenna 3 is provided on the base 100 and located on the first main There is a third feed end 3a between the antenna 1 and the second main antenna 2. The third feed end 3a is not in contact with the third feeder F3 and forms a coupled feed. The coupled feed formed by the first feed end 11a and the coupled feed formed by the third feed end 3a are used to improve the isolation between the first main antenna 1 and the auxiliary antenna 3.

輔助天線3更具有第五輻射部31，由於上述的第三饋線F3是設置在基底100的底面100d，第三饋入端3a延伸到基底100的底面100d，以與位於底面100d的第三饋線F3達到最佳的耦合。除此之外，第五輻射部31最主要設置於背面100b，在圖中，第五輻射部31具有兩個分支。 The auxiliary antenna 3 further has a fifth radiating part 31. Since the above-mentioned third feeder F3 is provided on the bottom surface 100d of the base 100, the third feed end 3a extends to the bottom surface 100d of the base 100 to communicate with the third feeder line F3 located on the bottom surface 100d. F3 achieves optimal coupling. In addition, the fifth radiating part 31 is mainly disposed on the back surface 100b. In the figure, the fifth radiating part 31 has two branches.

再者，輔助天線3的第五輻射部31與第四輻射部22彼此以相同方向延伸(也就是朝向第二端102延伸)，第五輻射部31與第三輻射部21彼此以相反方向延伸，用以提高第二主天線2與輔助天線3兩者之間的隔離度。換句話說，對第二天線2與輔助天線3兩者而言，饋點是盡量遠離(第二饋入端21a與第三饋入端3a彼此遠離)，且接地的第四輻射部22位於第三輻射部21(第二主天線2的部分)與第五輻射部31(輔助天線3的部分)之間，並且利用第四輻射部22與第五輻射部31以相同方向延伸的方式，以在當第五輻射部31與第三輻射部21彼此相向延伸靠近時能提供更佳的隔離度。而第五輻射部31與第三輻射部21彼此互相靠近延伸的目的是為了縮小天線的體積，在本發明實施例的設計情況，既能縮小天線體積也能提高隔離度。(反之，在傳統的較低困難度的設計情況，若使第五輻射部31與第三輻射部21彼此背向的延伸而互相遠離，將使天線體積增大，則對於隔離度的設計是容易達到的，並沒有挑戰性。) Furthermore, the fifth radiating part 31 and the fourth radiating part 22 of the auxiliary antenna 3 extend in the same direction to each other (that is, extend toward the second end 102 ), and the fifth radiating part 31 and the third radiating part 21 extend in opposite directions to each other. , to improve the isolation between the second main antenna 2 and the auxiliary antenna 3 . In other words, for both the second antenna 2 and the auxiliary antenna 3, the feeding points are as far away as possible (the second feeding end 21a and the third feeding end 3a are far away from each other), and the grounded fourth radiating part 22 It is located between the third radiating part 21 (part of the second main antenna 2) and the fifth radiating part 31 (part of the auxiliary antenna 3), and the fourth radiating part 22 and the fifth radiating part 31 extend in the same direction. , so as to provide better isolation when the fifth radiating part 31 and the third radiating part 21 extend toward each other and are close to each other. The purpose of extending the fifth radiating part 31 and the third radiating part 21 close to each other is to reduce the size of the antenna. In the design of the embodiment of the present invention, the size of the antenna can be reduced and the isolation can be improved. (On the contrary, in the traditional less difficult design situation, if the fifth radiating part 31 and the third radiating part 21 are extended back to each other and away from each other, the antenna volume will be increased, so the design of the isolation degree is Easy to achieve, not challenging.)

再者，第二饋線F2與第三饋線F3皆連接接地導體4， 接地導體4是第二銅箔C2的一部分，接地導體4具有一開槽41，且接地導體4是直接連接接地G。輔助天線3更具有接地部32，第二接地端22a與接地導體4的連接處設於開槽41的右側(較靠近第二端102)，輔助天線3的接地部32與接地導體4的連接處設於開槽41的左側(較遠離第二端102)，用以提高第二主天線2與輔助天線3兩者之間的隔離度。 Furthermore, both the second feeder F2 and the third feeder F3 are connected to the ground conductor 4, The ground conductor 4 is a part of the second copper foil C2. The ground conductor 4 has a slot 41, and the ground conductor 4 is directly connected to the ground G. The auxiliary antenna 3 further has a grounding portion 32. The connection between the second grounding terminal 22a and the grounding conductor 4 is located on the right side of the slot 41 (closer to the second end 102). The connection between the grounding portion 32 of the auxiliary antenna 3 and the grounding conductor 4 It is located on the left side of the slot 41 (further away from the second end 102 ) to improve the isolation between the second main antenna 2 and the auxiliary antenna 3 .
