Abstract
The present invention relates to a kind of miniaturization PCB slot antennas, the antenna body processed including PCB and its surface, the antenna body includes normal part and removal metal part, the removal metal part top is equipped with hatch frame, and the opening both ends load total capacitance or coupled structure of the hatch frame are to realize that distributed capacitor loads.When the PCB is multilayered structure, only in superficial layer making antenna body, metal part of the remainder layer within the scope of filling frame all removes.It is an advantage of the invention that while realizing antenna miniaturization, the wider beamwidth of antenna can be covered, meanwhile, PCB antenna also has the advantage of low cost, therefore the present invention has broad application prospects in a mobile device.
Description
Technical field
The present invention relates to slot antennas, and in particular to a kind of miniaturization PCB slot antennas.
Background technology
In the mobile communication equipment much minimized, because equipment size limits, Antenna Design is needed to minimize.And because
It is related to wavelength for the physical size of antenna, therefore Miniaturization Design can all generate unfavorable shadow to the bandwidth of operation of antenna, efficiency
It rings.WiFi communication is all supported in present mobile phone, PAD, unmanned plane, realizes that data, image and control signal pass by WiFi signal
It is defeated.WiFi antenna generally use Fig. 1 and monopole antenna shown in Fig. 2 or IFA (inverse-F antenna) antenna.
Prior art, antenna body needs are realized by individual metal material, as (printing is flexible by steel disc, FPC
Circuit board), the materials such as LDS (laser formation) or technique realizes.Because antenna body is needed fixed or supported, also need
It designs antenna holder or is fixed by apparatus casing.Making processing, assembly cost are increased, while antenna will also occupy
Certain space.
Invention content
Present invention aim to address the above problems, provide a kind of miniaturization PCB slot antennas, and antenna is directly produced on
On PCB, using two-dimensional antenna structure, antenna processing and fabricating and assembly cost are reduced, it may have better consistency；Together
When, this patent can reduce antenna size, while increasing the working frequency range of antenna by way of load.
To achieve the above object, the present invention provides the following technical solutions：
A kind of miniaturization PCB slot antennas, including PCB and its antenna body of surface processing, the antenna body include common
Part and removal metal part, the removal metal part top are equipped with hatch frame, and the opening both ends of the hatch frame add
Total capacitance or coupled structure are carried to realize that distributed capacitor loads.
Further, when the PCB is multilayered structure, only in superficial layer making antenna body, remainder layer is in filling frame range
Interior metal part all removes.
Further, the loading capacitance on the antenna body realizes double frequency or multifrequency resonance.
Further, the antenna body generally symmetrically or non-symmetrically form.
Further, the antenna body is adapted to in bulk and the higher mobile device of cost requirement.
Further, the superficial layer is first layer or last layer.
The beneficial effects of the present invention are：
The present invention can be realized by way of printing on PCB, reduced processing and fabricating, the assembly cost of antenna, carried
The high consistency of antenna, at the same time it can also reduce antenna size by way of load, the working frequency range of extended antenna is fitted
It closes and is applied to mobile phone, PAD, unmanned plane etc. in bulk and the higher mobile device of cost requirement.Realizing that antenna is small-sized
While change, the wider beamwidth of antenna can be covered, meanwhile, PCB antenna also has the advantage of low cost, therefore the present invention is moving
It is had broad application prospects in dynamic equipment.

Specific implementation mode
A kind of miniaturization PCB slot antennas as shown in Figure 3-4, including PCB and its antenna body 1 of surface processing, it is described
Antenna body 1 includes normal part 2 and removal metal part 3, and 3 top of removal metal part is equipped with hatch frame 4, described to open
The opening two-port of mouth structure 4 is the both ends A, B.
As shown in figure 5, loading total capacitance or coupled structure at the both ends AB of hatch frame 4 to realize that distributed capacitor adds
It carries, the size of antenna can be further decreased.
As shown in figure 3, if it is multi-layer PCB structure, only in superficial layer (first layer or last layer) making antenna body 1,
Metal part of the remainder layer in filling 5 range of frame all removes.
As shown in Figures 7 and 8, in order to increase the working frequency range of antenna, the loading capacitance on the antenna body 1, Ke Yishi
Existing double frequency or multifrequency resonance.
As shown in Fig. 4 and Fig. 6, generally symmetrically or non-symmetrically form or other the similar deformations of the antenna body 1, all
It can achieve the effect that similar.
The antenna body 1 is adapted to mobile phone, PAD, unmanned plane etc. to bulk and the higher mobile device of cost requirement
In.
The present invention can be realized by way of printing on PCB, reduced processing and fabricating, the assembly cost of antenna, carried
The high consistency of antenna, at the same time it can also reduce antenna size by way of load, the working frequency range of extended antenna is fitted
It closes and is applied to in bulk and the higher mobile device of cost requirement.While realizing antenna miniaturization, it can cover
The wider beamwidth of antenna, meanwhile, PCB antenna also have low cost advantage, therefore the present invention have in a mobile device it is wide
Application prospect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
