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, particularly relate to a kind of flat plane antenna with Parasitica.
Background technology
Along with making rapid progress of science and technology, the volume of radio communication device and size are also towards compact future development.While product pursues lightweight and miniaturization, the available space of the antenna in order to transceive communication signals will inevitably be compressed, and add the restriction of physical condition, the characteristic of antenna is subject to great impact especially.
For conventional I FA antenna, the efficiency of this type antenna is the user demand that can meet radio communication device under normal circumstances, but when have larger metal covering near time, the efficiency of antenna will decline suddenly, cannot meet the user demand of radio communication device.
Summary of the invention
The object of the present invention is to provide and a kind of there is the flat plane antenna improving efficiency.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of flat plane antenna, it comprises earth terminal, U-shaped Parasitica, rectangular radiation portion and feed side, described feed side connects Parasitica and Department of Radiation, described Department of Radiation comprises a pair straight-flanked ring, and a straight-flanked ring is positioned at left side, and another straight-flanked ring is positioned at right side, a pair parasitic that described Parasitica comprises a base portion and upwards extends from two ends, base portion left and right, described two straight-flanked rings are between this is to parasitic.
The Department of Radiation of flat plane antenna of the present invention comprises a pair straight-flanked ring, one straight-flanked ring is positioned at left side, another straight-flanked ring is positioned at right side, a pair parasitic that described Parasitica comprises a base portion and upwards extends from two ends, base portion left and right, described two straight-flanked rings are between this is to parasitic, and Department of Radiation can form the loop checking installation of both direction, produce common resonance, Parasitica can regulate the resonance of Department of Radiation, makes flat plane antenna effectively can resist interference from metal covering, improves the efficiency of flat plane antenna.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of flat plane antenna of the present invention.
Embodiment
Refer to shown in Fig. 1, flat plane antenna 10 of the present invention is in order to be used on radio communication device (not shown), this flat plane antenna 10 is formed in a vertical plane, can be made up of metal sheet or flexible printed circuit board, it comprises earth terminal 11, U-shaped Parasitica 12, isolated a pair connecting portion 13 in left and right, rectangular radiation portion 14 and feed side 15.At other execution modes, flat plane antenna 10 of the present invention is formed in a horizontal plane.
Earth terminal 11 is a horizontal lamellar body, and it is in order to be connected to the grounded part of radio communication device, for flat plane antenna 10 provides ground connection to act on.Earth terminal 11 is positioned at below Parasitica 12, and earth terminal about 11 two ends are connected with Parasitica 12 respectively by a junction 13, is formed with a rectangle gap 110 and forms loop checking installation between earth terminal 11, Parasitica 12 and connecting portion 13.
A pair parasitic 122 that Parasitica 12 comprises a base portion 121 and extends straight up from base portion about 121 two ends, parasitic about 122 is parallel, and parasitic 122 top has the branch 123 extended towards Department of Radiation 14.
Department of Radiation 14 is between two parasitic 122 of Parasitica 12, expand the broadband of flat plane antenna 10 low frequency and high frequency, Department of Radiation 14 is made up of a pair straight-flanked ring 141, one straight-flanked ring 141 is positioned at left side, another straight-flanked ring 141 is positioned at right side, this two straight-flanked ring 141 shares same inner side edge 142 and one is connected, and this inner side edge 142 is positioned at the middle position of Department of Radiation 14, thus makes Department of Radiation 14 can form the loop checking installation of both direction.
Feed side 15 is strip lamellar body always, and the Signal transmissions end (not shown) on itself and radio communication device is electrically connected, for flat plane antenna 10 plays signal feed-in effect.Feed side 15 is positioned at the below of Department of Radiation 14, is connected between the base portion 121 of Parasitica 12 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 straight-flanked ring 141, Department of Radiation 14 can form the loop checking installation of both direction, produce common resonance, the parasitic 122 of Parasitica 12 is positioned at Department of Radiation 14 both sides, the resonance of Department of Radiation 14 can be regulated, make flat plane antenna 10 effectively can resist interference from metal covering, improve the efficiency of flat plane antenna 10.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
