Description

Antenna module
Technical Field
The present invention relates to an Antenna module for a portable electronic product, and more particularly, to a Dual-band Patch Antenna (Dual-band Antenna) module.
Background
In recent years, portable electronic products have become increasingly popular with the development of mobile communication technologies, and common portable electronic products include: portable computers, mobile phones, multimedia players, and other portable electronic devices with hybrid capabilities. These portable electronic products transmit or receive radio waves through an antenna to transmit or exchange radio signals, thereby accessing a wireless network.
With the smaller and smaller volume of the conventional portable electronic product, the placement space of the antenna is also more and more limited. Therefore, the size of the antenna is limited by the space for placing the antenna and must be reduced accordingly. On the other hand, for portable electronic products, the operating frequency band of the antenna generates a wider bandwidth to cover more communication ranges and increase the data transmission rate.
The conventional patch antenna (patch antenna) has a small size and a low manufacturing cost, and thus can be widely applied to the conventional portable electronic products. One of the disadvantages of the panel antenna, however, is the narrow bandwidth. When the installation angle of the flat antenna installed in the portable electronic product is slightly deviated, the radiation efficiency of the antenna is greatly affected. Accordingly, it is still a goal of those skilled in the art to design an antenna with a small size and a wide bandwidth.
Disclosure of Invention
The present invention provides an Antenna module, which is a Dual-band patch Antenna (Dual-band Antenna) module, and the low frequency operating band and the high frequency operating band can respectively generate more than one resonance mode, so as to increase the bandwidth range of the low frequency operating band and the bandwidth range of the high frequency operating band.
In order to solve the above technical problems, one of the technical solutions of the present invention is to provide an antenna module, which includes a carrier plate, a radiation portion, a signal feed-in portion, and a grounding portion. The carrier plate is provided with a first surface and a second surface opposite to the first surface. The radiation part is arranged on the first surface and is provided with a strip-shaped slot, wherein the extension direction of the long axis of the radiation part is approximately the same as that of the long axis of the strip-shaped slot. The signal feed-in part is arranged on the radiation part and is adjacent to a middle section of the slotted hole. The grounding part is arranged on the second surface of the carrier plate and is provided with an L-shaped slotted hole, wherein the vertical projection of the slotted hole is partially overlapped with the L-shaped slotted hole in the projection area of the second surface.
One of the benefits of the present invention is that the antenna module provided by the present invention is a planar antenna module, which can respectively generate more than one resonance mode in the high frequency operating band and the low frequency operating band through the technical scheme of "mutual coupling of the radiation portion, the grounding portion, the slotted hole and the L-shaped slotted hole", thereby increasing the bandwidth of the low frequency operating band and the bandwidth of the high frequency operating band.
The antenna module provided by the invention has smaller volume, so that the space occupied by the antenna module can be reduced, and the whole volume of the portable electronic product can be further reduced. In addition, even if the size of the antenna module is reduced, the antenna module still has larger bandwidth in each operating frequency band. Therefore, when the antenna module is arranged in the portable electronic product, the radiation efficiency of the antenna is not influenced by slight deviation of the placing angle and the position of the antenna module.
For a better understanding of the features and technical content of the present invention, reference should be made to the following detailed description of the invention and accompanying drawings, which are provided for purposes of illustration and description only and are not intended to limit the invention.

Detailed Description
The following is a description of the embodiments of the "antenna module" disclosed in the present invention with reference to specific embodiments, and those skilled in the art will understand the advantages and effects of the present invention from the disclosure of the present specification. The invention is capable of other and different embodiments and its several details are capable of modification and various changes in detail without departing from the spirit and scope of the present invention. The drawings of the present invention are for illustrative purposes only and are not intended to be drawn to scale. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.
It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements or signals, these elements or signals should not be limited by these terms. These terms are used primarily to distinguish one element from another element or from one signal to another signal. In addition, the term "or" as used herein should be taken to include any one or combination of more of the associated listed items as the case may be.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic top view illustrating an antenna module according to an embodiment of the invention. Fig. 2 is a schematic bottom view of an antenna module according to an embodiment of the invention. The antenna module 1 provided by the invention can be suitable for being arranged in a portable electronic product and used for transmitting signals. The portable electronic product is, for example, a mobile phone, a tablet computer, a notebook computer or other portable electronic products. In addition, the antenna module 1 of the embodiment of the present invention is a dual-band planar antenna, i.e., can operate in a low-frequency operating frequency band and a high-frequency operating frequency band, and has a smaller volume, so as to reduce the internal space of the portable electronic product as much as possible, thereby further reducing the overall volume of the portable electronic product.
As shown in fig. 1 and fig. 2, an antenna module 1 provided in the embodiment of the present invention includes a carrier 10, a radiation portion 11, a ground portion 12, and a signal feeding portion 13.
The carrier plate 10 has a first face 10a and a second face 10b opposite to the first face 10 a. In an embodiment, the top view of the carrier 10 is rectangular, and the ratio of the length to the width of the carrier 10 is between 9 and 12, which can be set according to actual requirements. However, in the present invention, the top view appearance of the carrier 10 is not limited to the shape of the embodiment, and may be other geometric shapes.
The material constituting the carrier plate 10 is an insulating material, and is, for example, a composite material such as a glass fiber reinforced BT (bis-triazine) resin, FR4 glass fiber reinforced epoxy resin (polyimide), or a ceramic material such as alumina or magnesium titanate. In addition, in the embodiment, the thickness of the carrier plate 10 is very thin, which is approximately between 1.2mm and 2 mm. In one example, the thickness of the carrier 10 is 1.6 mm.
As shown in fig. 1, the radiation portion 11 is disposed on the first surface 10a of the carrier 10 to radiate energy. The radiation part 11 is substantially rectangular in plan view, and the radiation part 11 has a rectangular slot hole 110. The longitudinal axis extending direction of the radiating portion 11 is substantially the same as the longitudinal axis extending direction of the slotted hole 110.
The geometric center of the slotted hole 110 of the embodiment of the present invention is deviated from the geometric center of the radiating portion 11. The radiating portion 11 has a first short side S1 and a second short side S2 opposite to the first short side S1, and the slot 110 has a first end E1 and a second end E2 opposite to the first end E1. A first minimum distance D1 between the first end E1 of the slotted hole 110 and the first short side S1 of the radiating portion 11 is smaller than a second minimum distance D2 between the second end E2 and the second short side S2 of the radiating portion 11.
In addition, the ratio of the length of the slotted hole 110 to the length of the radiating part 11 is between 0.5 and 0.7. The length of the slotted hole 110 refers to the linear distance from the first end E1 to the second end E2.
Referring to fig. 1 again, the signal feeding portion 13 is disposed on the radiation portion 11 and is disposed adjacent to a middle portion of the slot 110 for feeding a signal. An imaginary straight connecting line between the first end E1 and the second end E2 of the slotted hole 110 passes through the signal feeding portion 13. Accordingly, the edge profile of the middle section of the slotted hole 110 adjacent to the signal feeding part 13 is curved into an arc shape in accordance with the outer edge of the signal feeding part 13. That is, the top view of the slotted hole 110 of the present embodiment is not a straight line, but at least has an arc segment 110 c. The arc-shaped segment 110c is separated from the signal feeding part 13, and the arc-shaped segment 110c is disposed around the signal feeding part 13, i.e., extends along a part of the outer edge of the signal feeding part 13. In addition, the arc-shaped segment 110c can adjust the coupling amount between the radiation portion 11 and the grounding portion 12, and can improve impedance matching and increase the bandwidth.
Referring to fig. 2 again, the grounding portion 12 is disposed on the second surface 10b of the carrier 10 to serve as a radiation reflection surface of the radiation portion 11. Since the grounding portion 12 is used as a radiation reflection surface of the radiation portion 11, the area of the grounding portion 12 is larger than the projection area of the radiation portion 11 vertically projected on the second surface 10b, so that the radiation energy generated by the antenna module 1 is relatively concentrated on the normal direction of the carrier plate 10.
Further, the land portion 12 of the present embodiment is also substantially rectangular in plan view, and the width of the land portion 12 is the same as the width of the radiation portion 11. However, the length of the grounding portion 12 is greater than that of the radiation portion 11, so that the area of the grounding portion 12 is greater than the projection area of the radiation portion 11 perpendicularly projected on the second surface 10 b.
Thus, the antenna module 1 can have higher directivity and antenna gain, thereby increasing the receiving and transmission range of signals. Since most of the radiation energy of the antenna module 1 is concentrated above the first surface 10a of the carrier 10, other components located in the portable electronic product and below the grounding portion 12 of the antenna module 1 will not interfere with the antenna module 1.
As shown in fig. 2, the ground portion 12 has an L-shaped slot 120 to be coupled with the slot 110 of the radiating portion 11. That is, the vertical projection of the slotted hole 110 on the second surface 10b partially overlaps the L-shaped slotted hole 120.
Further, the L-shaped slot 120 has a long line segment 121 and a short line segment 122 connected to the long line segment 121, wherein the short line segment 122 extends from one end of the long line segment 121 to an edge of the grounding portion 12. The long line segment 121 overlaps the projection area of the slot 110 perpendicularly projected on the second surface 10b, and the short line segment 122 does not overlap the projection area of the slot 110 perpendicularly projected on the second surface 10b at all.
The radiation portion 11 and the grounding portion 12 can be fabricated on two opposite surfaces (the first surface 10a and the second surface 10b) of the carrier 10 by a planar printing method. In another embodiment, two conductive sheets (e.g., copper foil) can be bonded to two sides of the carrier 10, and then the two conductive sheets are etched to form the radiation portion 11 and the grounding portion 12.
In addition, the antenna module 1 of the embodiment of the present invention further includes two positioning portions 15 disposed on the carrier plate 10. The two positioning portions 15 and the radiation portion 11 are spaced apart from each other and located on opposite sides of the radiation portion 11, respectively. The antenna module 1 can be fixed in the portable electronic product by two positioning portions 15. The positioning portion 15 is, for example, a positioning hole or a protruding engaging structure, wherein the engaging structure is, for example, a positioning post. When the positioning portion 15 is a positioning hole, other fixing elements can be matched, such as: the antenna module 1 is fixed or fixed in the portable electronic product by screws or bolts, but the invention is not limited thereto.
Referring to fig. 3, fig. 3 is a partial cross-sectional enlarged view of the antenna module according to the embodiment of the invention. Specifically, the antenna module 1 of the embodiment of the present invention may further include a coaxial cable 14. The coaxial cable 14 includes a signal transmission wire 141 and a grounding outer layer 140, wherein the grounding outer layer 140 covers the signal transmission wire 141 and is electrically insulated from the signal transmission wire 141. In the present embodiment, a soldering portion (not numbered) of the signal transmission wire 141 passes through the carrier 10 from the second surface 10b of the carrier 10 and is soldered to the radiating portion 11 to form the signal feeding portion 13. A welding portion of the grounding outer layer 140 does not penetrate through the carrier 10, but is directly electrically connected to the grounding portion 12 located on the second surface 10b of the carrier 10.
It is noted that, compared to disposing the signal feeding element 13 at the first end E1 or the second end E2 of the slot 110, the signal feeding element 13 of the embodiment of the invention is disposed adjacent to the middle portion of the slot 110, so that the spatial distribution of the radiation pattern generated by the antenna module 1 is relatively even.
The antenna module 1 of the embodiment of the present invention is a flat dual-band antenna, and can operate in a low-frequency operating band and a high-frequency operating band. Specifically, referring to fig. 4, fig. 4 is a graph illustrating reflection loss (return loss) of the antenna module according to an embodiment of the invention at different frequencies.
In this embodiment, the antenna module 1 needs to be operable in a frequency band of 2.4GHz (low frequency operation band) and a frequency band of 5GHz (high frequency operation band). The reflection loss of the antenna module 1 corresponding to each frequency in the low frequency operating band and the high frequency operating band needs to be lower than a predetermined value, so as to meet the industry requirements. In addition, the lower the reflection loss, the smaller the reflection of the antenna module 1, the larger the radiation power.
In the embodiment of the present invention, the radiation portion 11 having the slotted hole 110 and the grounding portion 12 having the L-shaped slotted hole 120 are coupled to each other, so that three first resonance modes M11 to M13 can be generated in a low frequency operation band, and two second resonance modes M21 and M22 can be generated in a high frequency operation band.
Referring to fig. 4, in the low frequency band, the grounding portion 12 with the L-shaped slot 120 can generate a first resonant mode M11, and the radiating portion 11 with the slotted hole 110 can generate another first resonant mode M13. In addition, the mutual coupling of the L-shaped slot 120 and the slotted slot 110 can generate another first resonant mode M12.
It should be noted that in the low frequency operating band, the frequency corresponding to the peak of the first resonant mode M11 is the minimum, the frequency corresponding to the peak of the other first resonant mode M13 is the larger, and the first resonant mode M12 coupled by the slot 110 and the L-shaped slot 120 is located between the other two first resonant modes M11 and M12. The three first resonant modes M11-M13 generated by the antenna module 1 of the embodiment of the present invention can make the reflection loss corresponding to each frequency within a specific frequency range, which is defined as the bandwidth BW1 of the low frequency operating band, less than-6 dB in the frequency band of 2.4 GHz.
Compared with the case where only one resonance mode is generated in the 2.4GHz band, the antenna module 1 of the embodiment of the invention can couple three first resonance modes M11-M13 through the grounding portion 12 having the L-shaped slot 120 and the radiating portion 11 having the slotted hole 110, so that the low frequency band has a larger bandwidth BW 1. In one embodiment, the low frequency band of operation is between 2.1GHz and 3GHz, and the bandwidth BW1 is 0.9 GHz.
Similarly, the antenna module 1 of the embodiment of the invention can generate two second resonant modes M21 and M22 in the 5GHz band, and the second resonant modes M21 and M22 make the reflection loss corresponding to each frequency in another specific frequency range, which is defined as the bandwidth BW2 of the high frequency operating band, less than-6 dB. In the embodiment of the present invention, the high frequency band is between 4.9GHz to 5.9GHz, and the bandwidth BW2 is 1 GHz.
Specifically, by changing the size of the slotted hole 110, the size of the L-shaped slotted hole 120, and the size of the overlapping area of the slotted hole 110 and the L-shaped slotted hole 120 in the thickness direction of the carrier 10, the frequencies corresponding to the peak values of the first resonance modes M11-M13 and the second resonance modes M21-M22 can be finely tuned, so that the low frequency band and the high frequency band have a larger bandwidth.
As can be seen from fig. 4, the antenna module 1 according to the embodiment of the present invention has a reflection loss of-10.078 dB (point a) at a frequency of 2.4GHz, a reflection loss of-9.3352 dB (point B) at a frequency of 2.5GHz, a reflection loss of-11.878 dB (point C) at a frequency of 5.15GHz, and a reflection loss of-7.2697 dB (point D) at a frequency of 5.85 GHz. Accordingly, it is proved that the antenna module 1 of the embodiment of the present invention can be operated in the frequency band of 2.4GHz and the frequency band of 5 GHz.
[ advantageous effects of the embodiments ]
One of the benefits of the present invention is that the antenna module 1 provided by the present invention is a flat dual-band antenna module, and the radiating portion 11, the grounding portion 12, the slotted hole 110 and the L-shaped slotted hole 120 are coupled to each other, so that more than one resonance mode can be generated in the high-frequency operating band and the low-frequency operating band, respectively, to increase the bandwidths of the low-frequency operating band and the high-frequency operating band. Accordingly, the volume of the antenna module 1 provided by the invention is smaller, so that the occupied space of the antenna module 1 can be reduced, and the whole volume of the portable electronic product can be further reduced. In addition, although the antenna module 1 of the embodiment of the present invention has a small volume, it can generate a larger bandwidth in each operating frequency band, and can be applied to more communication systems.
In addition, because the bandwidth of the antenna module 1 is wide, when the antenna module 1 is disposed in the portable electronic product, the radiation efficiency of the antenna module 1 is not affected by slight deviation of the placement angle and position of the antenna module 1.
The disclosure is only a preferred embodiment of the invention and should not be taken as limiting the scope of the invention, which is defined by the appended claims.
