Description
Technical field
The present invention relates to the technical field of wireless telecommunications system, refer in particular to a kind of antenna receiving unit.
Background technology
Antenna is as one of critical elements in field of wireless communication, along with the development of wireless telecommunications science and technology, at present, the kind of antenna is more and more, its scope related to is also more and more wider, although, existing antenna of a great variety, but oeverall quality is uneven, for example, with reference to shown in accompanying drawing 5, for a kind of common exterior aerial, it contains four loop antennas 21, three two parallel wires 22, one circuit board 23, one coaxial cable 24, four loop antennas 21 are in same plane and are arranged in a straight line, all connect with a two parallel wire 22 between loop antenna 21 adjacent between two, wherein, the two ends place in circuit plate 23 respectively of second two parallel wire 22, the signal end of circuit board 23 and signal output part are connected with the earth terminal of coaxial wire 24 and signal end respectively, although, the Received signal strength of this type of antenna is respond well, but the volume of this type of antenna is not suitable for indoor use, with reference to shown in accompanying drawing 6, for a kind of domestic aerial structure, main containing a loop antenna 31, one substrate 32 and a coaxial cable 33, wherein these loop antenna 31 two ends are inserted in substrate 32 respectively, and be connected with coaxial cable 33 earth terminal and signal end, although, this antenna is compared to above-mentioned exterior aerial, its size is less, easily be placed in indoor, but the volume of the loop antenna of this antenna 31 is still bigger than normal, and, the more above-mentioned exterior aerial of reception of this antenna is poor, simultaneously, because its loop antenna 31 is connected in vertical angle with substrate 32, overall volume cannot be reduced again, like this concerning the design of current Indoor antenna device, still have necessity of improvement further.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of compact, be available for users to any ornaments, institute takes up space less, and has the antenna receiving unit of very high-gain.
For achieving the above object, technical scheme provided by the present invention is: a kind of antenna receiving unit, include an antenna and a circuit board, described antenna forms by the metal wire rod that two strips are consistent is stacked, wherein, each strip metal wire rod all curves tricyclic structure, be specially one and there is the large ring of open type of three openings open type with an opening little ring consistent with two shapes, and, the large ring of this open type and two little rings of open type are all in same level, simultaneously, the opening two ends of these two little rings of open type are serially connected in the corresponding open top of the large ring of open type respectively, and, these two little rings of open type are 90 ° of angles, bottom when the large ring of described open type is vertically shelved is symmetrical horizontal rest portion, simultaneously, the bottom opening correspondence of the large ring of this open type is located between the horizontal rest portion of this symmetry, and, the bottom opening two ends of the large ring of this open type are 90 ° of angles with the horizontal rest portion connected separately respectively, and to lie against on circuit board and to weld with it, meanwhile, described circuit board is parallel with the same level of two little rings of open type with the large ring of open type.
The girth of the large ring of described open type is 0.78 λ.
The girth of the little ring of described open type is 0.3 λ.
The present invention is after have employed such scheme, its great advantage is because antenna of the present invention lies against on vertical circuit board, the volume of whole antenna receiving unit is made to greatly reduce, in addition, because the little ring of two serial connections can be equivalent to load, form large ring top loading structure, therefore, when receiving same frequency signal, the volume ratio existing loop antenna volume of this large ring is little, thus effectively reduce the volume of whole antenna receiving unit further, make its volume miniaturized as far as possible; In addition, because antenna of the present invention forms by the metal wire rod that two strips are consistent is stacked, two metal wire rod inductions produce in-phase signal, make original reception antenna signal because of synchronous relation, signal be strengthened, thus make Received signal strength more clear.In a word, by above improvement, antenna size of the present invention can reduce 20%, and reduced width 80% is more suitable for indoor use, and meanwhile, antenna gain promotes 20% than existing domestic aerial gain, also can clear Received signal strength for outdoor.

Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Shown in accompanying drawing 1 to accompanying drawing 4, antenna receiving unit described in the present embodiment, include antenna 1 and a circuit board 2, described antenna 1 forms by the metal wire rod that two strips are consistent is stacked, wherein, each strip metal wire rod described in the present embodiment all curves tricyclic structure, being specially a girth is that the large ring of the open type with three openings 3 of the 0.78 λ girth consistent with two shapes is 0.3 λ and has the little ring 4 of open type of an opening, and, the large ring of this open type 3 and two little rings 4 of open type are all in same level, simultaneously, the opening two ends of these two little rings of open type 4 are serially connected in the corresponding open top of the large ring 3 of open type respectively, and, the little ring 4 of these two open types is in 90 ° of angles, bottom when the large ring of open type described in the present embodiment 3 is vertically shelved is symmetrical horizontal rest portion, simultaneously, the bottom opening correspondence of the large ring of this open type 3 is located between the horizontal rest portion of this symmetry, and, the bottom opening two ends of the large ring of this open type 3 are 90 ° of angles with the horizontal rest portion connected separately respectively, and to lie against on circuit board 2 and to weld with it, meanwhile, described circuit board 2 is parallel with the same level of two little rings of open type 4 with the large ring of open type 3.After the above scheme of employing, because antenna 1 of the present invention lies against on vertical circuit board 2, so the volume of whole antenna receiving unit can be made to greatly reduce, in addition, because the little ring 4 of two serial connections can be equivalent to load, form large ring 3 top loading structure, therefore, when receiving same frequency signal, large ring 3 volume ratio of the present invention existing loop antenna volume is little, thus effectively can reduce the volume of whole antenna receiving unit further, make its volume miniaturized as far as possible; In addition, because antenna 1 of the present invention forms by the metal wire rod that two strips are consistent is stacked, the induction of this two metal wire rod produces in-phase signal, makes original reception antenna signal make to strengthen because of synchronous relation, thus make Received signal strength more clear, specifically see shown in accompanying drawing 4.In a word, by above improvement, antenna 1 size of the present invention can reduce 20%, reduced width 80%, is more suitable for indoor use, and meanwhile, the existing domestic aerial gain of antenna 1 ratio of gains of the present invention promotes 20%, so, also can clear Received signal strength for outdoor.Therefore, in sum, compared to existing technology, the present invention is a kind of miniature antenna receiving system being applicable to indoor and outdoors, wherein, is specially adapted to indoor use, is worthy to be popularized.
The examples of implementation of the above are only the preferred embodiment of the present invention, not limit practical range of the present invention with this, therefore the change that all shapes according to the present invention, principle are done, all should be encompassed in protection scope of the present invention.
