[ background of the utility model ]
In recent years, with the rapid development of wireless communication requirements, various convenient use requirements are achieved through the function of wireless communication transmission of mobile electronic devices. In the wireless communication transmission function, an antenna is required to transmit and receive wireless signals. Generally, when the operating frequency of the antenna is at its designed center frequency, the antenna can receive and transmit wireless communication signals efficiently and optimally, so as to ensure the transceiving efficiency and perform the best performance of the antenna. Generally, before shipping, a mobile electronic device is developed, assembled, tested, and verified, and after configuring an antenna, the working frequency of the antenna is measured and ensured as a center frequency, but in a subsequent development and production stage (e.g., DVT stage), an electronic component or a metal component is required to be additionally arranged near the antenna according to additional design considerations (e.g., EMI or ESD design requirements), which may cause the working frequency of the antenna to shift from the center frequency thereof, so that a research and development staff needs to worry and troublesomely readjust the overall design of the antenna to meet the requirement that the working frequency of the antenna is the center frequency, which is inconvenient and worthy of further research, study, and improvement.

[ description of the drawings ]
Other features and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments with reference to the accompanying drawings, in which:
FIG. 1 is a diagram illustrating an embodiment of an electronic device for wireless communication according to the present invention; and
fig. 2 is a schematic diagram, which further includes a metal part unit and a passive component unit in this embodiment.
[ detailed description ] embodiments
Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.
Referring to fig. 1, the electronic device for wireless communication of the present invention includes a housing 1, an antenna unit 2 disposed in the housing 1, and a circuit board 3 disposed in the housing 1 and connected to the antenna unit 2. The antenna unit 2 has a center frequency.
The circuit board 3 includes a processing unit 31 and a signal transmission circuit unit 32 connected to the processing unit 31. An operating frequency at which the antenna unit 2 transmits signals into the signal transmission circuit unit 32 is the center frequency. The signal transmission circuit unit 32 has a bending circuit 33 connecting the processing unit 31 and the antenna unit 2, and the processing unit 31 transmits and receives signals through the antenna unit 2 via the signal transmission circuit unit 32 at the center frequency.
In short, the design of the signal transmission circuit unit 32 and the antenna unit 2 is matched to ensure that the antenna unit 2 receives and transmits wireless communication signals at the central frequency, so that the processing unit 31 can transmit and receive signals at the central frequency through the signal transmission circuit unit 32 and the antenna unit 2.
By the design that the signal transmission circuit unit 32 is connected with the antenna unit 2 and the antenna unit 2 transmits signals into the signal transmission circuit unit 32 at the central frequency, the processing unit 31 can transmit and receive signals through the signal transmission circuit unit 32 at the central frequency through the antenna unit 2, and the problem that the antenna unit 2 cannot transmit signals at the central frequency due to the deviation of the working frequency of the antenna unit 2 is effectively avoided.
It should be particularly noted that, if it is necessary to add additional metal elements near the antenna unit 2 in the subsequent development and production stages (e.g. Design Verification Test, DVT stage), for example, referring to fig. 2, in this embodiment, the antenna further includes a metal part unit 4 disposed in the housing 1 and close to the antenna unit 2, and a passive element unit 5 disposed on the circuit board 3 and close to the meander circuit 33. The passive element unit 5 includes a plurality of passive elements 51. The bending circuit 33 of the signal transmission circuit unit 32 has a plurality of first bending protrusions 331 spaced apart from each other and a plurality of second bending protrusions 332 spaced apart from each other. The first bending protrusion 331 and the second bending protrusion 332 cooperate to form a plurality of bending gaps 333. The passive elements 51 are respectively disposed in the bending space 333 of the bending circuit 33. In this embodiment, the metal component unit 4 is disposed in the housing 1 and close to the antenna unit 2, so that the processing unit 31 can transmit and receive signals at the central frequency through the antenna unit 2 by using the bending circuit 33 and the passive element 51. In the present embodiment, the passive element 51 is a resistor, but not limited thereto, and may be a capacitor, an inductor, or other passive elements. Furthermore, when the metal component unit 4 is disposed near the antenna unit 2, the operating frequency of the antenna unit 2 will deviate from the central frequency to generate a low frequency deviation, so that the passive element 51 is disposed in the bending interval 333 of the bending circuit 33 as shown in fig. 2, and the transmission path from the antenna unit 2 to the processing unit 31 via the signal transmission circuit unit 32 is shortened, and the processing unit 31 can transmit and receive signals via the antenna unit 2 at the central frequency, so that the requirement of taking the operating frequency of the antenna as the central frequency can be met without changing the design of the antenna unit 2, thereby saving time and labor and greatly improving the production efficiency. Incidentally, in the present embodiment, the operating frequency of the antenna unit 2 is measured by a measuring device (not shown), and the operating frequency of the antenna unit 2 can be obtained, but not limited thereto. In the embodiment, the antenna unit 2 is an L5(GPS) signal antenna, and the center frequency of the antenna unit 2 is 1575.42MHz, but not limited thereto.
In addition, in the embodiment, because the operating frequency of the antenna unit 2 is biased to a low frequency, the passive element 51 is additionally disposed to bias the antenna unit 2 to a high frequency and return to the central frequency, but not limited thereto. In contrast, if the passive element 51 is originally disposed to transmit and receive signals at the center frequency due to the original design consideration, in the subsequent production stage, due to factors such as design modification, it is necessary to adjust the distance between the metal component unit 4 and the antenna unit 2, remove a part of the metal components of the metal component unit 4 or remove the whole metal components, and even other metal parts originally disposed in the vicinity of the antenna unit 2 (e.g. removing a metal plate or other metal parts in the vicinity of the antenna unit 2), causing the operating frequency of the antenna unit 2 to shift from the center frequency and generate a frequency offset to a high frequency, and at this time, by removing each passive element 51 one by one, the operating frequency of the antenna unit 2 is gradually shifted to a low frequency, and the operating frequency of the antenna unit 2 is the center frequency. However, if the passive components 51 of the passive component unit 5 are all removed, and the operating frequency of the antenna unit 2 is still at the high frequency offset from the central frequency, since the antenna unit 2 is locked and combined in the housing 1 by using a screw mode (not shown) in the present embodiment, the operating frequency of the antenna unit 2 can be adjusted to generate a low frequency offset by selecting a screw mode with a longer length, and the operating frequency of the antenna unit 2 can be returned to the central frequency, but not limited thereto. In addition, in the embodiment, the operating frequency of the antenna unit 2 can be adjusted to return to the center frequency by selecting the screw length of the screw type disposed near the antenna unit 2, but not limited thereto.
In summary, the electronic device for wireless communication of the present invention, by the design that the signal transmission circuit unit 32 is connected to the antenna unit 2 and the antenna unit 2 transmits signals into the signal transmission circuit unit 32 at the central frequency, the processing unit 31 can transmit and receive signals through the signal transmission circuit unit 32 via the antenna unit 2 at the central frequency, so as to effectively avoid the problem that the antenna unit 2 cannot transmit and receive signals at the central frequency with the best performance due to the deviation of the operating frequency of the antenna unit 2, thereby achieving the purpose of the present invention.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
