Main element symbol description
The present invention that the following detailed description will be further explained with reference to the above drawings.
Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
Referring to Fig. 1, a kind of dual-band antenna 100 includes substrate 20.Substrate 20 is made of non-conductive medium.Substrate 20 wraps
Include opposite the first face 22 and the second face 24.Substrate 20 forms the first slot 26 for running through the first face 22 and the second face 24.In this reality
It applies in mode, slot is rectangle.In other embodiments, the first slot 26 can be the shapes such as circle, diamond shape.
Please refer to Fig. 2, dual-band antenna 100 further includes the first metalwork 30, the second metalwork 32, the connection of the first metal
Part 40, the second metal connecting piece 50, the first metal fixing 60, the second metal fixing 62, third metal fixing 64 and gold
Belong to plate 70.First metalwork 30, the second metalwork 32, the first metal connecting piece 40 and the second metal connecting piece 50 are placed in the first face
Edge on 22 and positioned at the first slot 26.First metalwork 30 forms feeding point 34, and the second metalwork 32 forms grounding point 36.The
One metalwork 30 and the second metalwork 32 are located at two opposite edges of the first slot 26 of rectangle.First metal connecting piece 40 and
Second metal connecting piece 50 connect with the first metalwork 30 and is placed in the two sides of the first metalwork 30.
Metal plate 70 is placed on the second face 24 and forms the second slot 72 for communicating and being overlapped with the first slot 26.First metal is solid
The first metal connecting piece 40 is fixed in the one end for determining part 60, and the other end passes through substrate 20 and is fixed on metal plate 70, in this way, by first
Metal connecting piece 40, substrate 20 and metal plate 70 are fixed together and realize between the first metal connecting piece 40 and metal plate 70
It is conductively connected.The second metal connecting piece 50 is fixed in one end of second metal fixing 62, and the other end passes through substrate 20 and is fixed on
Metal plate 70, in this way, the second metal connecting piece 50, substrate 20 and metal plate 70 are fixed together and realize that the second metal connects
Conductive connection between part 50 and metal plate 70.The second metalwork 32, the other end are fixed in one end of third metal fixing 64
It is fixed on metal plate 70 across substrate 20, in this way, the second metalwork 32, substrate 20 and metal plate 70 to be fixed together and realize
Conductive connection between second metalwork 32 and metal plate 70.First metal fixing 60, the second metal fixing 62 and third
Metal fixing 64 is to play needle.
Since the first metalwork 30 is connect with the first metal connecting piece 40, the first metal connecting piece 40 passes through with metal plate 70
First metal fixing 60 is electrically conductive, and metal plate 70 is electrically conductive by third metal fixing 64 with the second metalwork 32, therefore,
Feeding point 34 can by the first metal connecting piece 40, the first metal fixing 60, metal plate 70 and third metal fixing 64 with
Grounding point 36 realizes electrical connection.
Since the first metalwork 30 is connect with the second metal connecting piece 50, the second metal connecting piece 50 passes through with metal plate 70
Second metal fixing 62 is electrically conductive, and metal plate 70 is electrically conductive by third metal fixing 64 with the second metalwork 32, therefore,
Feeding point 34 can by the second metal connecting piece 50, the second metal fixing 62, metal plate 70 and third metal fixing 64 with
Grounding point 36 realizes electrical connection.
It is electrically connected due to that can be achieved in two different ways between feeding point 34 and grounding point 36, so as to excite two kinds
The wireless signal of different frequency range.The length of first metal connecting piece 40 and the second metal connecting piece 50 can be according to the frequency to be excited
Section is configured.Since metal plate 70 offers the second slot 72 of closure, signal radiates on the direction perpendicular to the second slot 72,
Therefore, clearance zone only need to be reserved on the direction perpendicular to the second slot 72, and clearance zone need not be reserved around substrate 20.Such as
This, dual-band antenna 100 will occupy less space when being placed in electronic equipment.
Specifically, the first metal connecting piece 40 include be fixed on the first metalwork 30 one end the first sheet metal 42 and with
The connection of first sheet metal 42 and spaced third metalwork 44 and the 4th metalwork 46.Third metalwork 44 and the 4th metal
Perpendicular to the first sheet metal 42 and it is parallel to the first metalwork 30.
Second metal connecting piece 50 include be fixed on the first metalwork 30 one end the second sheet metal 52 and with the second gold medal
Belong to the fifth metal part 54 that piece 52 connects.Fifth metal part 54 is perpendicular to the second sheet metal 52 and parallel with the first metalwork 30.
Second sheet metal 52 connect with the first sheet metal 42 and is interconnected to form linear type, the second sheet metal 52 and the first sheet metal 42
It is made of one piece.
The signal that above-mentioned dual-band antenna 100 is excited radiates on the direction perpendicular to the second slot 72, only need to perpendicular to
Clearance zone is reserved on the direction of second slot 72, is intended to reserved clearance zone around antenna more in the past and is more saved space.
Those skilled in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as within spirit of the invention, it is to the above embodiments
It is appropriate change and variation all fall in it is disclosed in this invention within the scope of.
