Description
Technical field
The utility model relates to a kind of inverse-F antenna shielding construction.
Background technology
Along with expanding economy, various communication apparatus comes into the life of people just gradually, they are helping us to carry out better live and work, and the transmission of communication apparatus is fixed against antenna, along with miniaturized and microminiaturized demand, the height of antenna and size are had higher requirement, and the interference of external signal, make a big impact to the transmission of signal, cause the inconvenience on using.
For this reason, designer of the present utility model is because above-mentioned defect, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of inverse-F antenna shielding construction, to overcome above-mentioned defect.
Utility model content
The technical problems to be solved in the utility model is: when the interference of external signal, makes a big impact to the transmission of signal, causes the inconvenience on using.
For solving the problem, the utility model discloses a kind of inverse-F antenna shielding construction, comprising shield, antenna and radio circuit, it is characterized in that:
Described radio circuit is positioned on printed circuit board (PCB), and described printed circuit board (PCB) is also provided with a ground end, and described radio circuit includes high-frequency component;
Described shield is tabular and covers whole radio circuit, and described shield comprises upper surface and side surface and is provided with a through hole, and described shield is electrically connected on to be held describedly;
Described antenna is provided with radiant body, earth terminal and feed side, and described radiant body is positioned at the top of described shield, and described earth terminal extends downward described shield from one end of described radiant body;
One end, described feed side is connected to radiant body, and the other end stretches into described through hole and is connected to described radio circuit.
Wherein: the height of described shield is 2mm-3mm.
Known by said structure, inverse-F antenna shielding construction of the present utility model has following technique effect:
1, structure is simple, the basis coordinating miniaturization provides shielding action, ensure that the accurate transmission of signal;
2, its structure is simple, and with low cost, practicality is better.
Detailed content of the present utility model obtains by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation

Described inverse-F antenna shielding construction comprises shield, antenna and radio circuit, and described antenna is inverse-F antenna.
Described radio circuit 27 is positioned on printed circuit board (PCB) 23, and described printed circuit board (PCB) 23 is also provided with a ground end 231, resistor 25 and capacitor 26, and described radio circuit 27 also includes high-frequency component 271.
Described shield is tabular and covers whole radio circuit 27, and it comprises upper surface 212 and side surface 213 and is provided with a through hole 211, and the height of described shield is 2mm-3mm.
Described shield is electrically connected on holds 231 describedly, and shield radio frequency circuit 27 and high-frequency component 271 carry out signal shielding thus, avoid interference.
Described antenna is provided with radiant body 221, earth terminal 222 and feed side 223, described radiant body 221 is positioned at the top of described shield, described earth terminal 222 extends downward described shield from one end of described radiant body 221, because shield holds 231 to be connected with ground, therefore earth terminal 222 is held be electrically connected with ground, one end, described feed side 223 is connected to radiant body 221, and the other end stretches into described through hole 211 and is connected to described radio circuit 27.
Thus, antenna is located at above shield, can effectively reduces area and size.
Known by said structure, inverse-F antenna shielding construction tool of the present utility model has the following advantages:
1, structure is simple, the basis coordinating miniaturization provides shielding action, ensure that the accurate transmission of signal;
2, its structure is simple, and with low cost, practicality is better.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the utility model do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of specification and the appended claim fallen into above.
