1. Field of Invention
The present invention relates to an antenna module, and more particularly to an antenna module disposed on a transparent substrate.
2. Related Art
With the development of wireless communication technologies, a user may use a wireless communication system to transmit information without being limited by landforms, which results in an increase in number and type of electronic products using the wireless communication technologies, for example, portable electronic devices such as a notebook computer, a cell phone and a personal digital assistant (PDA), and thus an antenna for receiving and sending electromagnetic wave signals becomes one of the essential components in a wireless communication device.
Taking the notebook computer as an example, to meet the purchasing trend of the current consumers, the notebook computers in the market are all designed and developed to be lighter and thinner. Therefore, the size of the antenna for receiving and sending the radio electromagnetic wave signals should be smaller, or the structure and shape thereof should be changed, so that the antenna can be successfully disposed in a limited space inside the notebook computer.
A conventional antenna module may be an independent component additionally disposed inside the electronic device (portable electronic devices such as a notebook computer, a cell phone and a PDA). For example, the additional disposition of the antenna module inside the cell phone as an independent component may cause a larger volume of the cell phone. Therefore, the antenna module is directly installed on a mother board of the cell phone in the prior art, so as to reduce the volume occupied by the antenna module. However, the antenna module of such a design occupies a large area on the mother board, thus affecting the disposition of other electronic components (such as a capacitor, an inductor, a resistor, a diode and a transistor) on the mother board. In other words, since the development of the cell phone has a thinner and smaller trend, the space inside the cell phone is more crowded. Therefore, the manner of disposing the antenna module inside the cell phone in the prior art causes many difficulties when engineers design the space distribution of components inside the cell phone.
Accordingly, the present invention is an antenna module and an electronic device having the same, so as to solve the problem in the prior art that the space layout and distribution of components inside the electronic device are difficult.
The present invention provides an antenna module, which comprises a transparent substrate and an antenna component, and the antenna component is disposed on the transparent substrate. The antenna component comprises at least one radiation portion, a feed portion and a grounding portion. The grounding portion is located at a corner of the transparent substrate, the grounding portion has a first strip portion and a second strip portion, and an end of the first strip portion is approximately perpendicularly connected to an end of the second strip portion.
The present invention provides an electronic device, which comprises a mother board, a display panel and an antenna module. The display panel is overlapped on and coupled to the mother board. The antenna module comprises a transparent substrate and an antenna component. The transparent substrate is overlapped on the display panel, and the transparent substrate and the mother board are located on two opposite surfaces of the display panel. The antenna component is disposed on the transparent substrate, and the antenna component comprises at least one radiation portion, a feed portion and a grounding portion. The grounding portion is located at a corner of the transparent substrate, the grounding portion has a first strip portion and a second strip portion, and an end of the first strip portion is approximately perpendicularly connected to an end of the second strip portion.
The present invention provides a touch module, which comprises a touch screen and an antenna module. The antenna module comprises a transparent substrate and an antenna component. The transparent substrate is overlapped on the touch screen, and the transparent substrate and a mother board are located on two opposite surfaces of the display panel. The antenna component is disposed on the transparent substrate, and the antenna component comprises at least one radiation portion, a feed portion and a grounding portion. The grounding portion is located at a corner of the transparent substrate, the grounding portion has a first strip portion and a second strip portion, and an end of the first strip portion is approximately perpendicularly connected to an end of the second strip portion.
In the antenna module of the present invention, the shape of the grounding portion is improved to a shape appropriate to be placed at the corner of the transparent substrate, so that the antenna component can be directly formed and overlapped on the transparent substrate on the display panel.
In addition, since the antenna component is directly formed and overlapped on the transparent substrate on the display panel, the manufacturing process thereof is relatively simple, and the space of the electronic device occupied by the antenna module can be reduced. Furthermore, compared with the prior art in which the disposition of the antenna component on the mother board causes difficulty for the layout of other electronic components, the antenna module of the present invention can avoid the difficulty in the prior art. Therefore, such an antenna module has good structural integrity, and facilitates the smaller and thinner development trend of the electronic device.
These and other aspects of the present invention will become apparent from the following description of the preferred embodiment taken in conjunction with the following drawings, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.
The accompanying drawings illustrate one or more embodiments of the invention and, together with the written description, serve to explain the principles of the invention. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment, and wherein:
Referring to
The antenna component 300 is formed at a corner of the transparent substrate 200. In this embodiment, the transparent substrate 300 may be formed on the transparent substrate 200 through an electroplating manner, but is not limited thereto. For example, the antenna component 300 may be formed on the transparent substrate 200 by means of printing, sputtering, laser engraving, pressing or by other chemical or physical vapor deposition methods.
In this embodiment, the radiation portion 310 comprises a first radiation portion 311 and a second radiation portion 312. The first radiation portion 311 has a first axle portion 3111, and the second radiation portion 312 has a second axle portion 3121, a first block 3122 and a second block 3123. The first block 3122 and the second block 3123 are electrically connected to the second axle portion 3121. An end of the first axle portion 3111 is electrically connected to an end of the second axle portion 3121. The first block 3122 and the second block 3123 act as impedance matching.
In addition, a frequency band range of the first radiation portion 311 is different from that of the second radiation portion 312, for example, the frequency band range of the first radiation portion 311 is 2.4 GHZ to 2.4835 GHZ, and the frequency band range of the second radiation portion 312 is 4.9 GHZ to 5.35 GHZ, which are not limited thereto. It should be noted that, the number of the radiation portion 310 is not intended to limit the present invention. For example, the number of the radiation portion 310 may be two as shown in
Moreover, the grounding portion 330 has a first strip portion 331 and a second strip portion 332. An end of the first strip portion 331 is approximately perpendicularly and electrically connected to an end of the second strip portion 332, so that a combination of the first strip portion 331 and the second strip portion 332 is generally in an L-shaped geometric form. In addition, the grounding portion 330 is located at a corner of the transparent substrate 200, and thus the first strip portion 331 and the second strip portion 332 are respectively located at two edges of the corner of the transparent substrate 200.
Another embodiment of the antenna module 100 according to the present invention will be introduced hereinafter. The manner of forming the antenna component 300 on the transparent substrate 200, the structure of the grounding portion 330 and the frequency band range of the radiation portion 310 are already illustrated in detail above, and will not be described herein again. Merely the structure of the radiation portion 310 will be illustrated below.
An electronic device 400 having the antenna module 100 of this embodiment will be illustrated below.
Referring to
In addition, the transparent substrate 200 of the antenna module 100 may be disposed on the touch screen 420 as an additional component. Or, the transparent substrate 200 is a part of components of the touch screen 420. In other words, the touch screen 420 comprises the transparent substrate 200, and the antenna component 300 of the antenna module 100 is disposed on the transparent substrate 200 of the touch screen 420.
When the touch screen 420 of the touch module is overlapped on the display panel 430 and matches with the display panel 430 to form a touch screen. Moreover, the display panel 430 may be a rigid display, such as a liquid crystal display (LCD), or may be a flexible display, such as an electronic paper (E-paper).
In this embodiment, the display panel 430 is overlapped on and coupled to the mother board 440, and the touch screen 420 is overlapped on the display panel 430. In other words, the touch screen 420 and the mother board 440 are located on two opposite surfaces of the display panel 430. The transparent substrate 200 disposed on the touch screen 420 may be a glass substrate. The antenna component 300 is disposed on the transparent substrate 200. It should be noted that, the mother board 440, the display panel 430, the touch screen 420, the size of the transparent substrate 200, the widths of the first strip portion 331 and the second strip portion 332, and the width from the radiation portion 310 to the grounding portion 330 are presented in a manner that can be clearly understood by a reader. However, the proportions of the components in the drawings are not intended to limit the present invention. Taking a practical case as an example, the widths of the first strip portion 331 and the second strip portion 332 may be smaller than the width of the transparent substrate 200 covered by a frame 410 of the electronic device 400, thus nearly occupying no plane area of the transparent substrate 200. The electronic components of the mother board 440 in the drawings are not the focus of the present invention, and are not shown.
It should be noted that, the electronic device 400 having the touch screen 420 is taken as an example in this embodiment, and is not intended to limit the present invention. For example, in another embodiment of the present invention, the electronic device 400 may not comprise the touch screen 420, and the transparent substrate 200 is directly overlapped on the display panel 430.
Through the above design, the antenna module 100 does not need to be disposed on the mother board 440, and thus the circuit layout space of the mother board 440 is saved, so as to avoid the difficulty of disposing other electronic components on the mother board 440.
In the antenna module 100 of the present invention, the first strip portion 331 and the second strip portion 332 of the grounding portion 330 are combined. An end of the first strip portion 331 is connected to an end of the second strip portion 332, and thus the first strip portion 331 and the second strip portion 332 are in an L-shaped geometric form, so that the shape of the grounding portion 330 is improved to a shape appropriate to be placed at the corner of the transparent substrate 200, and accordingly the antenna component 300 can be directly formed and overlapped on the transparent substrate 200 on the display panel 430.
In the electronic device 400 and the antenna module thereof according to the present invention, the antenna component 300 is directly formed at the corner of the transparent substrate (for example, a glass substrate) of the touch screen 420. The manufacturing process is simple, and the volume of the electronic device 400 is nearly not increased. Moreover, the antenna module 100 of the present invention is not disposed on the mother board 440, which does not cause difficulty to the disposition of other electronic components on the mother board 440. Compared with the prior art in which the disposition of an antenna line on the mother board 440 causes difficulty in the disposition of other electronic components, the antenna module 100 of the present invention has good structural integrity, thus actually solving the difficulty in the circuit design of the mother board 440 in the prior art. Moreover, since the disposition of the antenna module 100 nearly causes no increase of the volume of the electronic device 400, it facilitates the smaller and thinner development trend of the electronic device 400.
