Detailed Description
The invention is further illustrated, but is not limited, by the following examples.
Referring to fig. 1, 2, 3 and 4, the present embodiment provides a high gain antenna module 1, which includes a substrate 11, a dipole antenna 12, a reflection section 13, a guiding section 14 and a coaxial transmission line 15. The base 11 has a disk shape, and the base 11 has a disk inner portion 11a, a side wall surface 11b, an upper surface 11c, and a lower surface 11d. The upper surface 11c and the lower surface 11d are opposite to each other, and the upper surface 11c and the lower surface 11d are connected to each other by the side wall surface 11 b. The substrate 11 also has a low dielectric constant portion 11e, and the low dielectric constant portion 11e is disposed in a groove of the substrate 11, and the groove is used for accommodating a low dielectric constant material with a dielectric constant lower than that of the substrate 11, and the dielectric constant of the low dielectric constant portion 11e is lower than that of the substrate 11 itself. The dipole antenna 12 is disposed on the substrate 11, and has a first radiator 121 and a second radiator 122, the first radiator 121 has a first contact 121a, the second radiator 122 has a second contact 122a, the first contact 121a and the second contact 122a are located in a disc interior 11a (as indicated by a dotted line range) of the substrate 1, and the first radiator 121 and the second radiator 122 extend from the disc interior 11a toward a sidewall surface 11b of the substrate 11. The reflection section 13 is disposed on the side wall 11b of the substrate 11 and on the first side of the dipole antenna 12, and the middle of the reflection section 13 has a middle contact 131, wherein the low dielectric constant portion 11e is disposed between the dipole antenna and the reflection section. The guide section 14 is disposed on the side wall 11b of the substrate 11 and on the second side of the dipole antenna 12, and the length of the guide section 14 is shorter than the length of the reflection section 13. In other words, the dipole antenna 12 is positioned between both the reflective segment 13 and the guide segment 14. Also, it is worth mentioning that in terms of the characteristics of the radiation pattern, the gain on the second side of the dipole antenna 12 (on the side where the guiding section 14 is located) is higher, while the gain on the first side of the dipole antenna 12 (on the side where the reflecting section 13 is located) is relatively lower. In terms of manufacturing materials, the substrate 11 is, for example, a glass fiber substrate, and the dipole antenna 12, the reflection section 13 and the guide section 14 are metal conductors, for example, metal structures manufactured by three-dimensional printing technology. In addition to the cooperation between the reflective segment 13 and the guide segment 14, the low dielectric constant portion 11e of the present embodiment makes the equivalent dielectric constant value of the first side (the side where the reflective segment 13 is located) of the dipole antenna 12 lower (compared to the case where the second side has only the substrate 11 and does not have the low dielectric constant portion 11 e), so as to further increase the gain of the side (the second side) where the guide segment 14 is located. The low dielectric constant portion 11e is filled with, for example, a plastic material or a plastic material, or even with ordinary air, but is not limited thereto.
The coaxial transmission line 15 has a central conductor 151 and an outer conductor 152, the coaxial transmission line 15 extends from the side wall 11b toward the disc interior 11a to provide a feeding portion 15a, the central conductor 151 of the feeding portion 15a is connected to the first contact 121a of the first radiator 121, and the outer conductor 152 of the feeding portion 15a is connected to the second contact 122a of the second radiator 122. The outer conductor 152 is electrically connected to the intermediate contact 131 of the reflective segment 13 via the conductive portion 16 (see fig. 4), so as to enhance the reflective effect of the reflective segment 13. In detail, the portion of the coaxial transmission line 15 extending toward the disc interior 11a and crossing the sidewall 11b is a bridging portion 15b, and the outer conductor 152 located at the bridging portion 15b is electrically connected to the intermediate contact 131 of the reflection section 13 via the conductive portion 16, and the connection between the coaxial transmission line 15 and the reflection section 13 can enhance the reflection effect of the reflection section 13, so as to enhance the maximum gain of the high-gain antenna. It should be noted that, the feeding portion 15a of the coaxial transmission line 15 is one end of the coaxial transmission line 15, generally cuts the coaxial transmission line 15 and leads the central conductor 151 and the outer conductor 152, the central conductor 151 may be connected to the first contact 121a by welding, and the outer conductor 152 may be connected to the second contact 122a by welding, and the other end of the coaxial transmission line 15 is generally provided with a radio frequency connector for connecting to a radio frequency circuit system. Further, the conductive portion 16 is a conductor (e.g., metal), and when the coaxial transmission line 15 extends from the circumferential edge 11b toward the disc interior 11a, the outer layer insulator of the portion of the coaxial transmission line 15 extending over the intermediate contact 131 may be removed (peeled) to be soldered to the outer layer conductor 152 and the intermediate contact 131 by soldering, so that the solder material may be used as the conductive portion 16, but the invention is not limited to the conductive connection method using solder. Note that, in fig. 4, the conductive portion 16 is shown by an oval-shaped hatched area, and when the conductive portion 16 is actually implemented with solder, for example, the solder may be spread over (fully coated with) the portion of the insulating body removed, so as to completely cover the exposed outer conductor 152 and firmly weld and fix the intermediate contact 131. The conductive portion 16 is used for the conductive and fixed connection function, and other embodiments may be functionally equivalent to a related fixing mechanism such as a metal latch or a metal spring. In addition, as an alternative embodiment, the dipole antenna 12 disposed on the upper surface 11c may be disposed on the lower surface 11d instead, and the central conductor 151 of the feeding element 15a is connected to the first contact 121a by a via manner instead, and the outer conductor 152 of the feeding element 15a is connected to the second contact 122a by a via manner instead.
Further, the substrate 11 has a first radial axis X and a second radial axis Y, which are orthogonal to each other through the disk inner portion 11a, and the first radial axis X passes through the intermediate contact 131 of the reflection section 13. Furthermore, considering the function of the dipole antenna 12, the first radiator 121 and the second radiator 122 are generally symmetrical. In order to reduce the area of the substrate 11, the ends of the first radiator 121 and the second radiator 122 may be bent, for example, in fig. 1, in the vicinity of the sidewall 11b, and may bypass along the edge of the sidewall 11 b. In an embodiment, the first radiator 121 of the dipole antenna 12 has a first radial portion 1211, a first bending portion 1212 and a first final arc portion 1213, the second radiator 122 has a second radial portion 1221, a second bending portion 1222 and a second final arc portion 1223, the first final arc portion 1213 and the second final arc portion 1223 are located at the circumferential edge 11b, the first radial portion 1211 and the second radial portion 1221 are parallel to the second radial axis Y, and the first radiator 121 and the second radiator 122 are symmetrical to each other according to the first radial axis X. Preferably, the coaxial transmission line 15 is parallel to the first radial axis X, and the dipole antenna 12, the reflection section 13 and the guiding section 14 each have the first radial axis X as a symmetry axis.
Furthermore, in the embodiment of fig. 1, the radiation pattern is characterized in that the circular arc segment structure of the reflection segment 13 is longer than the circular arc segment structure of the guide segment 14, the middle contact 131 of the reflection segment 13 is just in the middle of the reflection segment 13, and the reflection segment 13 and the guide segment 14 are co-matched with the dipole antenna 12 so that the radiation pattern also uses the first radial axis X as the symmetry axis, and the direction of the highest gain is the forward direction of the first radial axis X, that is, when the disc inner 11a is used as a reference, the direction towards the guide segment 14 is the direction of the highest gain, and the direction towards the middle contact 131 of the reflection segment 13 is the direction of the lowest gain.
Next, referring to fig. 5, fig. 5 is a schematic diagram showing another embodiment of the high gain antenna module 2 according to the present invention, which includes a substrate 21, a dipole antenna 22, a reflection section 23, a guiding section 24 and a coaxial transmission line 25. The difference from the previous embodiment is that the substrate 21 of the embodiment of fig. 5 has a high dielectric constant portion 21f in addition to the low dielectric constant portion 21e, the high dielectric constant portion 21f is located between the guide section 24 and the dipole antenna 22, and the high dielectric constant portion 21f is used for accommodating a high dielectric constant material having a dielectric constant higher than that of the substrate 21. Other parts of the high-gain antenna module 2 except for the high dielectric constant portion 21f are the same as those of the high-gain antenna module 1, and the same parts are not described in with reference to the foregoing description.
The high-gain antenna module provided by the embodiment of the invention is connected with the assembly of the coaxial transmission line by using the substrate, so that the high-gain antenna with three-dimensional structure, small size and remarkable protruding maximum gain is realized. The method also has the technical effect of high stability and has high industrial application value. Especially, the antenna has the effect of improving communication efficiency for the built-in antenna product applied to the notebook computer product, and has great potential market application competitiveness.
