Embodiment 1

[0022] see figure 1 , figure 1 It is a flow chart of an antenna manufacturing method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the antenna manufacturing method provided by the embodiment of the present invention may include:

[0023] Step 101: Obtain a position point on the shield layer of the Universal Serial Bus with a proper length from one end.

[0024] Step 102: Disconnect the shielding layer at the position point, and divide it into a first shielding layer and a second shielding layer.

[0025] Step 103: Connect one end of the radio frequency choke coil to the first shielding layer, and connect the other end to the second shielding layer.

[0026] The appropriate length of the distance from one end is a quarter of the wavelength corresponding to the center frequency of the working frequency band.

[0027] The function of the radio frequency choke coil is to limit the received signal to the shielding layer with a proper length from...

Embodiment 2

[0030] see figure 2 , figure 2 It is a flowchart of an antenna manufacturing method provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the antenna manufacturing method provided by the embodiment of the present invention may include:

[0031] Step 201: Starting from one end of the USB cable, measure an appropriate length of the shielding layer, and obtain a point where the shielding layer is disconnected.

[0032] Calculate the quarter length of the wavelength corresponding to the center frequency of the working frequency band;

[0033] Taking one end of the USB cable as a starting point, measure the calculated length, and obtain the position point where the shielding layer is disconnected.

[0034] If you are receiving digital TV signals, since the working frequency bands of digital TV signals are 170MHz-240MHz and 470MHz-860MHz, you should measure a quarter of the wavelength of the digital TV signal whose center frequency is 205MHz in the low...

Embodiment 3

[0046] see image 3 , image 3 It is a schematic diagram of an antenna provided by Embodiment 3 of the present invention. Such as image 3 As shown, the antenna provided in the embodiment of the present invention may include:

[0047] Universal Serial Bus and RF chokes;

[0048] The universal serial bus is used to obtain a position on the shielding layer that is an appropriate length from one end to disconnect the shielding layer and divide it into a first shielding layer and a second shielding layer;

[0049] One end of the radio frequency choke is connected to the first shielding layer, and the other end is connected to the second shielding layer.

[0050] The appropriate length is a quarter length of the wavelength corresponding to the center frequency of the working frequency band.

[0051] For example, if a digital TV signal is received, the measured length is 1 / 4 of the wavelength of the digital TV signal with a frequency of 205MHz.

[0052] One end of the radio fr...

Abstract

The invention discloses an antenna and a manufacturing method thereof. The method comprises: obtaining a position point of which the tip has proper length on a shielding layer of Universal Serial Bus (USB); breaking the shielding layer at the position point into a first shielding layer and a second shielding layer; and connecting one end of a radio-frequency choke (RFC) with the first shielding layer and the other end thereof with the second shielding layer. The antenna comprises the USB and the RFC. In the invention, the antenna can be manufactured easily and conveniently, can be carried conveniently and does not occupy the space of the terminal equipment, thus being favorable for miniaturization of terminal equipment and solving the limitation on audience number.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna and a manufacturing method thereof. Background technique [0002] With the implementation of digital TV standards, various wireless portable terminals (such as wireless data cards, digital video broadcast cards, etc.) capable of receiving digital TV programs are more and more popular in the market. The main challenge of realizing wireless digital TV signal reception on a portable terminal is how to design a broadband antenna covering both the 170MHz-240MHz frequency band and the 470MHz-860MHz frequency band within the limited space of the portable terminal. [0003] An existing antenna solution is a built-in microstrip antenna, that is, the antenna is built into a portable terminal with a digital video broadcast chip, and the antenna transmits the received signal to the portable terminal for processing, and then transmits it to the display terminal, and the display te...
