Description
Technical field
It is more particularly to a kind of to increase the dual-band antenna of isolation the present invention relates to a kind of dual-band antenna.
Background technology
It has been trend and more and more that WiFi AP, which possess double frequency technology, on the market at present, and existing WiFi products antenna is most
It is designed as with PIFA (Planar Inverted-F Antenna) or IFA (Inverted-F Antenna) dual-band antenna
It is main, and mostly using the design of Fig. 1 frame modes, existing dual-band antenna includes：Single body, and the single body includes:
Grounding parts 101；
Load point 201, it is electrically connected with grounding parts 101；
First irradiation unit 301, extends from load point 201；
Second irradiation unit 401, extends from load point 201, and the second irradiation unit 401 and the first irradiation unit 301 are located at load point 201
The same side, and the second irradiation unit 401 be arranged in parallel with the first irradiation unit 301；
Connecting portion 501, is connected between grounding parts 101, the first irradiation unit 301 and the second irradiation unit 401, and the load point
201 are located at the central region of connecting portion 501.
The first irradiation unit 301 is different from the length of the second irradiation unit 401 in Fig. 1, and the first irradiation unit 301 is longer, and second
Irradiation unit 401 is shorter, and the length of irradiation unit, which represents, gives off different frequencies, so possessing the function of dual-band antenna.
But, because the first irradiation unit 301 and the second irradiation unit 401 in Fig. 1 are designed at the same side, each other because leaning on very much
Interference cases closely are tended to have, so isolation is poor.
The content of the invention
It is a primary object of the present invention to provide a kind of to increase the dual-band antenna of isolation.
The present invention provides a kind of dual-band antenna；It includes：Single body, and the single body includes:
Grounding parts；
Load point, it is electrically connected with grounding parts；
First irradiation unit, from load point extension；
Second irradiation unit, from load point extension, and the second irradiation unit and the first irradiation unit are in 180 degree angle, the first irradiation unit and
Second irradiation unit is respectively the antenna for covering different frequency section.
Especially, the dual-band antenna is PIFA antennas or IFA antennas.
Compared with prior art, the second irradiation unit and the first irradiation unit of dual-band antenna of the present invention are in 180 degree angle, with
Mutual interference is prevented, increases the isolation between two frequencies naturally.In addition, the second irradiation unit and the first irradiation unit are launched into one
Font, can make the height of dual-band antenna more flat, be adapted to assembling.
【Brief description of the drawings】
Fig. 1 is the structural representation of existing dual-band antenna.
Fig. 2 is the structural representation of dual-band antenna of the present invention.
【Embodiment】
Refer to shown in Fig. 2, the present invention provides a kind of dual-band antenna；It includes：Single body, and the single body includes:
Grounding parts 10；
Load point 20, it is electrically connected with grounding parts 10；
First irradiation unit 30, extends from load point 20；
Second irradiation unit 40, extends from load point 20, and the second irradiation unit 40 and the first irradiation unit 30 are in 180 degree angle, first
Irradiation unit and the second irradiation unit are respectively the antenna for covering different frequency section.
In the present embodiment, the dual-band antenna is PIFA antennas or IFA antennas, can be according to the Frequency Design first of radiation
The first irradiation unit 30 in the length of the irradiation unit 40 of irradiation unit 30 and second, the present embodiment is longer, and the second irradiation unit 40 is shorter.In
In the present embodiment, with the connecting portion 50 of a standard bending shape between the first irradiation unit 30, the second irradiation unit 40 and grounding parts 10
Connection, load point 20 is located at the central region of connecting portion 50.
In the present embodiment, the dual-band antenna includes single load point, adjusts the position of load point to adjust double frequency day
The internal resistance of line.First irradiation unit and the second irradiation unit are launched into in-line.The shape of first irradiation unit and the second irradiation unit can be
In-line, can also be spiral extension.First irradiation unit and the second irradiation unit extend in asymmetrically shape.
Separately, the width of first irradiation unit and the second irradiation unit can be set according to the requirement of internal resistance size, the first irradiation unit and
Second irradiation unit can be with wide, can not also be wide.
The second irradiation unit 40 and the first irradiation unit 30 of dual-band antenna of the present invention are in 180 degree angle, mutual to prevent
Interference, increases the isolation between two frequencies naturally.In addition, the second irradiation unit 40 and the first irradiation unit 30 are launched into in-line, it can make
The height of dual-band antenna is more flat, is adapted to assembling.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
