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.
