Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention thereto.
Referring to fig. 1, fig. 2, fig. 3 and fig. 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 guide 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 sidewall surface 11b, an upper surface 11c, and a lower surface 11 d. The upper surface 11c and the lower surface 11d are opposed to each other, and the upper surface 11c and the lower surface 11d are connected to each other by a side wall surface 11 b. The substrate 11 also has a low-k portion 11e, the low-k portion 11e is disposed in a slot of the substrate 11 for accommodating a low-k material having a dielectric constant lower than that of the substrate 11, and the low-k portion 11e has a dielectric constant 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 the disk interior 11a of the substrate 1 (as indicated by the dashed line), and the first radiator 121 and the second radiator 122 both extend from the disk interior 11a toward the sidewall 11b of the substrate 11. The reflection section 13 is disposed on the sidewall surface 11b of the substrate 11 and located on the first side of the dipole antenna 12, and the middle of the reflection section 13 has an intermediate contact 131, wherein the low-k portion 11e is located between the dipole antenna and the reflection section. The guiding section 14 is disposed on the side wall surface 11b of the substrate 11 and located on the second side of the dipole antenna 12, and the length of the guiding section 14 is shorter than that of the reflecting section 13. In other words, the dipole antenna 12 is located between both the reflection section 13 and the guide section 14. Also, it is worth mentioning that in terms of the characteristics of the radiation pattern, the gain is higher at the second side of the dipole antenna 12 (at the side where the guide section 14 is located), and the gain is relatively lower at the first side of the dipole antenna 12 (at the side where the reflection section 13 is located). 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 guiding section 14 are metal conductors, for example, metal structures manufactured by a three-dimensional printing technique. In addition to the cooperation between the reflection section 13 and the guide section 14, the low-k portion 11e is utilized to lower the equivalent dielectric constant of the first side (the side where the reflection section 13 is located) of the dipole antenna 12 (relative to the case where the second side has only the substrate 11 and does not have the low-k portion 11 e), so as to further improve the gain of the side (the second side) where the guide section 14 is located. The low dielectric constant portion 11e is filled with baolilong material, plastic material, or even ordinary air, but not limited thereto.
Furthermore, the coaxial transmission line 15 has a central conductor 151 and an outer conductor 152, the coaxial transmission line 15 extends from the sidewall surface 11b to the disc interior 11a to provide a feeding portion 15a, the central conductor 151 located in the feeding portion 15a is connected to the first contact 121a of the first radiator 121, and the outer conductor 152 located in 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 reflection section 13 through the conductive portion 16 (see fig. 4) to improve the reflection effect of the reflection section 13. Specifically, the portion of the coaxial transmission line 15 extending toward the disk interior 11a and crossing the sidewall 11b is the crossover portion 15b, the outer conductor 152 located at the crossover portion 15b is conductively connected to the intermediate contact 131 of the reflection section 13 through the conductive portion 16, and the connection mode of the coaxial transmission line 15 and the reflection section 13 can improve the reflection effect of the reflection section 13, so as to improve 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, the coaxial transmission line 15 is cut off and the central conductor 151 and the outer conductor 152 are led out, the central conductor 151 is connected to the first contact 121a by welding, the outer conductor 152 is 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 the radio frequency circuit system. Furthermore, the conductive portion 16 is a conductor (e.g. metal), and when the coaxial transmission line 15 extends from the circumferential edge 11b to the disc interior 11a, the coaxial transmission line crosses the intermediate contact 131 of the reflection section 13, the outer layer insulator of the portion of the coaxial transmission line 15 crossing the intermediate contact 131 is removed (peeled off), and solder is welded to the outer layer conductor 152 and the intermediate contact 131 by soldering, so that the solder material here can be used as the conductive portion 16, but the present invention is not limited to the conductive connection method using solder. Note that the conductive portion 16 in fig. 4 is indicated by an oval oblique line region, and when the conductive portion 16 is actually implemented by solder, for example, the solder may be spread over (or coated over) the portion where the insulator is removed, so as to completely cover the exposed outer conductor 152 and firmly weld it to the intermediate contact 131. The conductive portion 16 has a function of conducting and fixedly connecting, and other embodiments may be functionally equivalent to, for example, a metal tenon, a metal spring, or other related fixing mechanisms. 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, the central conductor 151 of the feeding portion 15a is connected to the first contact 121a by a via method instead, and the outer conductor 152 of the feeding portion 15a is connected to the second contact 122a by a via method instead.
Further, the substrate 11 has a first radial axis X and a second radial axis Y, both of which are perpendicular to each other through the disc inner portion 11a, and the first radial axis X passes through the intermediate contact 131 of the reflective section 13. Furthermore, considering the function of the dipole antenna 12, the first radiator 121 and the second radiator 122 are generally symmetrical. In addition, in order to reduce the usable 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, the ends are bent near the sidewall surface 11b and go round the edge of the sidewall surface 11 b. In an embodiment, the first radiator 121 of the dipole antenna 12 has a first diameter portion 1211, a first bent portion 1212, and a first end arc portion 1213, the second radiator 122 has a second diameter portion 1221, a second bent portion 1222, and a second end arc portion 1223, the first end arc portion 1213 and the second end arc portion 1223 are all located at the circumferential edge 11b, the first diameter portion 1211 and the second diameter portion 1221 are all 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 are respectively symmetric about the first radial axis X.
In the embodiment of fig. 1, the arc structure of the reflection section 13 is longer than the arc structure of the guide section 14, the intermediate point 131 of the reflection section 13 is located at the middle of the reflection section 13, the reflection section 13 and the guide section 14 are jointly fitted to the dipole antenna 12, so that the radiation pattern is also symmetric about the first radial axis X, and the direction of the highest gain is the forward direction of the first radial axis X, that is, the direction toward the guide section 14 is the direction of the highest gain, and the direction toward the intermediate point 131 of the reflection section 13 is the direction of the lowest gain, based on the disc interior 11 a.
Next, referring to fig. 5, the embodiment of fig. 5 is another embodiment of the high-gain antenna module 2 provided by the present invention, and 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-k portion 21f besides the low-k portion 21e, the high-k portion 21f is located between the guiding segment 24 and the dipole antenna 22, and the high-k portion 21f is used for accommodating a high-k material with a dielectric constant higher than that of the substrate 21. The components of the high-gain antenna module 2 other than the high-permittivity portion 21f are the same as those of the high-gain antenna module 1, and the same components are described with reference to the foregoing description and are not described in .
