Embodiment
The embodiment of the invention provides a kind of antenna and manufacture method thereof, the method can be created antenna simply, easily, and this antenna is the easy to carry but also space of occupied terminal equipment not only, is conducive to the miniaturization of terminal equipment, and can solve the problem of the digital TV watching number of restriction.
For the ease of the embodiment of the invention is further understood, below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Embodiment one:
See also Fig. 1, the flow chart of a kind of method for manufacturing antenna that Fig. 1 provides for the embodiment of the invention one.As shown in Figure 1, the method for manufacturing antenna that provides of the embodiment of the invention can comprise:
Step 101: the location point that obtains a termination suitable length of distance at the USB screen.
Step 102: at described location point screen is disconnected, be divided into the first screen and secondary shielding layer.
Step 103: an end of radio-frequency choke is connected with described the first screen, and the other end is connected with described secondary shielding layer.
The suitable length of a termination of described distance is 1/4th length of the centre frequency institute corresponding wavelength of working frequency range.
The effect of described radio-frequency choke is to be used for will receiving signal limitations in a described termination suitable length screen of distance USB line the realization antenna.According to the method for the embodiment of the invention, described suitable length screen can be namely to be the first screen or secondary shielding layer.
The method for manufacturing antenna that the embodiment of the invention provides, not only can create simply, easily antenna, and this antenna is not only easy to carry but also need not the space of occupied terminal equipment, thereby is beneficial to the miniaturization of terminal equipment, and the problem that can solve the digital TV watching number of restriction.
Embodiment two:
See also Fig. 2, the flow chart of a kind of method for manufacturing antenna that Fig. 2 provides for the embodiment of the invention two.As shown in Figure 2, the method for manufacturing antenna that provides of the embodiment of the invention can comprise:
Step 201: from a termination of USB line, measure the suitable length screen, obtain to disconnect the location point of screen.
/ 4th length of the centre frequency institute corresponding wavelength of evaluation work frequency range;
Take termination of USB line as starting point, measure the described length that calculates, obtain to disconnect the location point of screen.
If what receive is digital television signal, because the working frequency range of digital television signal has 170MHz~240MHz and 470MHz~860MHz, (centre frequency that is 170MHz~240MHz) is 1/4th length of the digital television signal wavelength of 205MHz so should measure the low frequency operation frequency range.
Step 202: the location point at described disconnection screen disconnects screen, is divided into the first screen and secondary shielding layer, and described the first screen is described suitable length screen.
For the ease of introducing, the present embodiment specifically with the first screen as described suitable length screen.Namely be that described the first screen one end is connected with a described termination of described USB line, the other end can free radio-frequency choke etc. joins.
Certainly, also can be with the secondary shielding layer as described suitable length screen.Namely be that described secondary shielding layer one end is connected with a described termination of described USB line, the other end can free radio-frequency choke etc. joins.
The embodiment of the invention just for the ease of introducing, is not done the restriction of concrete title.
Step 203: adopt radio-frequency choke with described the first screen be connected the secondary shielding layer and connect.
Wherein, can adopt welding manner or crimping mode that one end of described radio-frequency choke is connected with described the first screen;
Adopt welding manner or crimping mode that the other end of described radio-frequency choke is connected with described secondary shielding layer.
The relation of utilizing the reactance of radio-frequency choke to be directly proportional with frequency, can be limited on described the first screen receiving signal (such as digital television signal etc.), the length of described the first screen namely is the length of antenna, and described the first screen is antenna with being connected of radio-frequency choke.
Since the length of antenna should with 1/4th length coupling of the centre frequency institute corresponding wavelength of its working frequency range; So the embodiment of the invention adopts radio-frequency choke to be connected with described the first screen, purpose is exactly 1/4th length coupling for the centre frequency institute corresponding wavelength of the length that makes antenna and its working frequency range, so that antenna can normally receive signal.
The method for manufacturing antenna that the invention described above embodiment provides, not only can create simply, easily antenna, and this antenna is not only easy to carry but also need not the space of occupied terminal equipment, thereby is beneficial to the miniaturization of terminal equipment, and the problem that can solve the digital TV watching number of restriction.

See also Fig. 3, the schematic diagram of a kind of antenna that Fig. 3 provides for the embodiment of the invention three.As shown in Figure 3, the antenna that provides of the embodiment of the invention can comprise:
USB and radio-frequency choke;
Described USB is used at the location point that screen obtains apart from a termination suitable length described screen being disconnected, and is divided into the first screen and secondary shielding layer;
Described radio-frequency choke one end links to each other with described the first screen, and the other end links to each other with described secondary shielding layer.
Described suitable length is 1/4th length of the centre frequency institute corresponding wavelength of working frequency range.
Digital television signal such as what receive, the length that then measures be frequency be 205MHz the digital television signal wavelength 1/4th.
Described radio-frequency choke one end can adopt welding manner or crimping mode to link to each other with described the first screen; The other end can adopt welding manner or crimping mode to link to each other with the secondary shielding layer of described disconnection.
If described suitable length screen is described the first screen, then described radio-frequency choke is used for receiving signal (such as digital television signal etc.) and is limited to described the first screen, and the length of described the first screen namely is the length of antenna; If described suitable length screen is described secondary shielding layer, then described radio-frequency choke is used for receiving signal (such as digital television signal etc.) and is limited to described secondary shielding layer, and the length of described secondary shielding layer namely is the length of antenna.
Since the length of antenna should with 1/4th length coupling of the centre frequency institute corresponding wavelength of its working frequency range; So the embodiment of the invention adopts radio-frequency choke, purpose is exactly 1/4th length coupling for the centre frequency institute corresponding wavelength of the length that makes antenna and its working frequency range, so that antenna can normally receive signal.
The antenna that the embodiment of the invention provides can also link to each other with the terminal equipment with digital video broadcasting chip by suitable match circuit network, realizes digital TV antenna.
Above-mentioned a kind of antenna that the embodiment of the invention is provided is introduced, and this antenna is the easy to carry but also space of occupied terminal equipment not only, is conducive to the miniaturization of terminal equipment, and can solve the problem of the digital TV watching number of restriction.
