Antenna is as one of important original paper of wireless communications products, and the size of its performance and size is directly connected to the quality of wireless communication product.Along with the miniaturization development built-in aerial of wireless communications products replaces external antenna gradually, become the main flow of Antenna Design.
But general built-in printed antenna adopts the design of single shaft minute surface, usually existing need to larger ground plane and headroom district.Subject matter is that gain is low, directivity is poor, and antenna performance can change and worsen along with peripheral environment, and has cost high, efficiency is low, the Similar Problems such as time-consuming, are usually to reduce antenna gain and bandwidth is cost if need to address the above problem, so, how in not reducing antenna gain and bandwidth, design radiance with less area good, gain relatively high, good directionality printed antenna be a major challenge.
Summary of the invention
The present invention, in order to solve the technical problem existing in prior art, provides a kind of printed antenna, and low to solve existing printed antenna gain, directivity is poor, and antenna performance can change and the problem of deterioration along with peripheral environment.
To achieve the above object, technical scheme of the present invention is as follows:
A kind of printed antenna, is arranged on substrate, and described printed antenna comprises:
Antenna feed point, for feed-in electromagnetic wave signal;
Radiant body, for receiving and dispatching electromagnetic wave signal;
Grounding parts; Antenna feed point and grounding parts are on one side same, and described radiant body comprises:
Sawtooth Department of Radiation, one side of described sawtooth Department of Radiation is sawtooth radiant section, described sawtooth radiant section is to one side indentation projection of antenna feed point and grounding parts;
The first connecting portion, connects described grounding parts and the second connecting portion, and parallel in sawtooth Department of Radiation;
The second connecting portion, connects described the first connecting portion and described sawtooth Department of Radiation;
The 3rd connecting portion, connects described sawtooth Department of Radiation and antenna feed point.
Further be characterized as described grounding parts and be L-type, and antenna feed point is in same level.
Further be characterized as and between described grounding parts, antenna feed point and radiant body, form headroom district.
Further be characterized as the same surface that described grounding parts, antenna feed point and radiant body are all arranged at substrate.
Further being characterized as described the first connecting portion is middle narrow right-angled trapezium.
Further being characterized as another side relative with sawtooth radiant section in described sawtooth Department of Radiation is to be provided with a rectangular protrusions to one side of sawtooth radiant section at middle part.
Further being characterized as described antenna feed point is rectangular shape.
Further being characterized as described antenna feed point is L-type with the 3rd connecting portion and is connected.
Further being characterized as described grounding parts is L-type with the first connecting portion and is connected.
Advantage of the present invention is: high for gaining, and good directionality, and antenna performance can, along with peripheral environment changes and worsen, and not have cost relatively low, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention
