Abstract
The invention relates to a planar antenna which comprises a ground terminal, a U-shaped parasitic portion, a rectangular radiation portion and a feed-in end. The feed-in end is connected with the parasitic portion and the radiation portion, the radiation portion comprises a pair of rectangular rings, one rectangular ring is located on the left side, and the other rectangular ring is located on the right side. The parasitic portion comprises a base portion and a pair of parasitic arms which extends upwards from the left end and the right end of the base portion. The two rectangular rings are located between the pair of parasitic arms, the radiation portion can form an annular loop in two directions to generate common resonance, the parasitic portion can adjust the resonance of the radiation portion so that the planar antenna can effectively prevent interference of a metal face, and efficiency of the planar antenna is improved.
Description
Technical field
The present invention relates to a kind of flat plane antenna, more particularly, to a kind of flat plane antenna with Parasitica.
Background technology
Make rapid progress with scientific and technological, the volume of radio communication device and size also develop towards compact direction.
While product pursues lightweight and miniaturization, the available space of antenna institute in order to receive and dispatch signal of communication will necessarily be pressed
Contracting, along with the restriction of physical condition, the characteristic of antenna is even more and is subject to strong influence.
, the efficiency of this type antenna is to meet radio communication device under normal circumstances taking traditional IFA antenna as a example
Use demand, but when have larger metal covering near when, the efficiency of antenna will suddenly decline it is impossible to meet radio communication dress
The use demand put.
Content of the invention
Object of the present invention is to provide a kind of have the flat plane antenna improving efficiency.
For realizing object defined above, the present invention adopts the following technical scheme that：A kind of flat plane antenna, it includes earth terminal, U-shaped is posted
Life portion, rectangular radiation portion and feed side, described feed side connects Parasitica and Department of Radiation, and described Department of Radiation includes a pair of rectangle
Ring, a straight-flanked ring be located at left side, another straight-flanked ring be located at right side, described Parasitica include a base portion and from about base portion two ends to
A pair of parasitic of upper extension, described two straight-flanked rings be located at this to parasitic between.
The Department of Radiation of flat plane antenna of the present invention includes a pair of straight-flanked ring, and a straight-flanked ring is located at left side, and another straight-flanked ring is located at
Right side, described Parasitica include a base portion and from about base portion upwardly extending a pair of the parasitic in two ends, described two straight-flanked ring positions
Between this is to parasitic, Department of Radiation can form the loop checking installation of both direction, produces common resonance, and Parasitica can be adjusted
The resonance of section Department of Radiation, makes the interference that flat plane antenna can be effective against from metal covering, improves the efficiency of flat plane antenna.
Brief description
Fig. 1 is the schematic diagram of flat plane antenna of the present invention.
Specific embodiment
Refer to shown in Fig. 1, flat plane antenna 10 of the present invention in order to be used on radio communication device (not shown), this plane
Antenna 10 is formed in a vertical plane, can be made up of metal sheet or flexible printed circuit board, it includes earth terminal 11, U-shaped is posted
A pair of connecting portion 13, rectangular radiation portion 14 and feed side 15 that life portion 12, left and right are spaced apart.In other embodiment, the present invention
Flat plane antenna 10 is formed in a horizontal plane.
Earth terminal 11 is a horizontal lamellar body, and it, in order to connect to the grounded part of radio communication device, is flat plane antenna 10
Ground connection effect is provided.Earth terminal 11 is located at below Parasitica 12, and earth terminal 11 about two ends are passed through a connecting portion 13 and posted respectively
Life portion 12 connects, and is formed with a rectangular gap and forms loop checking installation between earth terminal 11, Parasitica 12 and connecting portion 13.
Parasitica 12 includes a base portion 121 and a pair of the parasitic 122 extending straight up from base portion 121 about two ends,
Parasitic 122 about is parallel, and parasitic 122 top has the branch 123 extending towards Department of Radiation 14.
Department of Radiation 14 is located between two parasitic 122 of Parasitica 12, has expanded the width of flat plane antenna 10 low frequency and high frequency
Band, Department of Radiation 14 is made up of a pair of straight-flanked ring 141, and a straight-flanked ring 141 is located at left side, and another straight-flanked ring 141 is located at right side, and this two
Straight-flanked ring 141 shares same inner side edge 142 and one is connected, and this inner side edge 142 is located at the middle position of Department of Radiation 14, so that
Department of Radiation 14 can form the loop checking installation of both direction.
Feed side 15 is strip lamellar body always, and it is electrically connected with the signal transmission end (not shown) on radio communication device
Connect, be that flat plane antenna 10 plays signal feed-in effect.Feed side 15 is located at the lower section of Department of Radiation 14, is connected to the base portion of Parasitica 12
Between 121 and the middle part of Department of Radiation 14.
The Department of Radiation 14 of flat plane antenna 10 of the present invention is made up of a pair of straight-flanked ring 141, and Department of Radiation 14 can form two sides
To loop checking installation, produce common resonance, the parasitic 122 of Parasitica 12 is located at Department of Radiation 14 both sides, can adjust radiation
The resonance in portion 14, makes the interference that flat plane antenna 10 can be effective against from metal covering, improves the efficiency of flat plane antenna 10.
Although being example purpose, have been disclosed for the preferred embodiment of the present invention, the ordinary skill people of this area
Member various will change it is realized that in the case of scope and spirit of the present invention disclosed in without departing from by appending claims
It is possible for entering, increasing and replacing.
