Abstract
The utility model discloses a double G-shaped plane surrounding type miniature antenna with multiple frequency ranges. The antenna comprises two G-shaped parts, wherein one G-shaped part is arranged inside the other G-shaped part; and the two G-shaped parts at least share a part of structure. Due to the adoption of the additional G-shaped part, the double G-shaped plane surrounding type multi-frequency range miniature antenna enhances the structural coupling, leads the antenna routing to be shorter, only requires 1/5-1/6 wavelength compared with the original 1/4 wavelength and reduces the dimension of the antenna from 25*40 to 15*30, thereby realizing the miniaturization purpose. Meanwhile, the original wireless performance of the antenna is ensured.
Description
Technical field
The utility model relates to a kind of multiband aerial, relates in particular to a kind of double-G type planar circular multi-frequency band miniature antenna, belongs to the wireless communication technique field.

In the wireless communication field prior art, present more common G shape antenna (shown in accompanying drawing one), its principle is to adopt the corresponding respectively branch road one of 1/4 wavelength and two to carry out radiation, be mainly used in the structure of wireless terminal antenna (based on antenna for mobile phone), in order to reach the predetermined wireless performance of antenna, antenna size is general bigger, common specification: 25*40; In recent years along with development in wireless communication technical field, the particularly appearance of 3G, Radio Terminal Function is strengthened, the wireless module integrated level improves, give the space of antenna also more and more littler, keep simultaneously wireless performance original or that surpass again, and this needs especially a kind of new antenna structure to can be good at realizing this function.
The utility model content
Technical problem at above-mentioned existence, the purpose of this utility model is: proposed a kind of Radio Terminal Function and strengthened, the wireless module integrated level improves, and volume is little, keeps original again simultaneously or the novel double-G type planar circular multi-frequency band miniature antenna of the wireless performance that surpasses.
Technical solution of the present utility model is achieved in that a kind of double-G type planar circular multi-frequency band miniature antenna, comprise two G type parts, one of them G type parts is arranged on another G type components interior, and two shared at least a part of structures of G type parts.
Preferably, described G type parts, comprise receive first, receive two, connecting portion one; Described reception first with receive two relative settings, described connecting portion one connects and receives first, reception two, and is the G type.
Preferably, described the 2nd G type parts are arranged on a G type components interior, comprise receive three, receive four, connecting portion two; Described reception four is arranged on the described connecting portion one, described reception three with receive four and be oppositely arranged, described connecting portion two, comprise receive first and with the part of the first described connecting portion one that links to each other of described reception, connect to receive three, receive four, and be the G type.
Preferably, described double-G type planar circular multi-frequency band miniature antenna also includes pad, and signal is directly from the pad feed-in.
Preferably, the sheet material of described double-G type planar circular multi-frequency band miniature antenna adopts FPC flexible circuit board, thickness 0.1-0.2.
The double-G type planar circular multi-frequency band miniature antenna of the utility model scheme, because G type of many employings, strengthened between structure and be coupled, make the antenna cabling shorter, originally need 1/4 wavelength, only need the 1/5-1/6 wavelength length now, make antenna size narrow down to (15*30), thereby realized microminiaturized purpose from requiring 25*40 originally; And keep the original wireless performance of antenna.
