Description
Technical field
The present invention relates to printed antenna technical field, more particularly to a kind of high efficiency low-loss printed antenna.
Background technology
With the development of radio communication science and technology, user can not be limited by landform, and letter is carried out using wireless telecommunications
Breath transmission, and antenna is as one of critical elements in wireless communication field, traditional antenna whether dipole antenna or spiral shell
Rotation antenna, yagi aerial etc. all occupy sizable volume, present trend and trend have not been met, so industry in recent years
Small volume is designed using Principle of Antenna is calmed down, relatively thin printing type aerial, the antenna volume is small and cost is cheap, Er Qieke
Apply in each different field.
With the continuous development of antenna, the volume requirement of antenna product is constantly diminished, but so enters to also result in day together
The universal not high phenomenon of the efficiency of line product, thus also have while design a small volume the low-loss antenna of high efficiency into
The problem faced for antenna designer.
The content of the invention
It is an object of the invention to provide one kind for problem above can still have rate low-loss under smaller size smaller
High efficiency low-loss printed antenna.
In order to realize the above object the technical solution adopted by the present invention is：A kind of high efficiency low-loss printed antenna, including
Substrate, insulating barrier, radiating element, the radiating element are arranged at substrate surface in non-closed centrosymmetric structure and radiated
The first signal feed-in part and secondary signal feeding portion are formed respectively on the breakpoint of unit two, it is relative with two breakpoints on radiating element
One side form loading unit for adjusting radiating element radiation characteristic, the insulating barrier is covered in radiating element, first
On signal feed-in part, secondary signal feeding portion and loading unit surface.
Further, first signal feed-in part, secondary signal feeding portion, radiating element, loading unit material for copper,
One of which in iron, aluminium, silver.
Further, the radiating element is regular shape or irregular rectangle, square, circular configuration.
Further, the width on described radiating element one side is 3-4 times of other hem width degree.
Further, the radiating element overall length is equal to resonant frequency wavelength.
The beneficial effects of the invention are as follows：High efficiency low-loss printed antenna provided by the invention can have under less volume
There is the low-loss feature of high efficiency.
