Embodiment
The utility model to be explained in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
As shown in Figure 1, 2, a kind of double-ring antenna utilizing mobile phone metal back cover, comprise the metal back cover of mobile phone, metal back cover disclosed in the present embodiment is syllogic metal back cover, and comprise top back of the body lid 1, middle part back of the body lid 3 and bottom back of the body lid 2, wherein back of the body lid 2 in bottom is provided with main antenna, middle part back of the body lid 3 connects the PCB earth terminal 4 of Mobile phone PCB, diversity antenna and GPS/BT/WIFI antenna are positioned at top back of the body lid 1, and this is traditional design scheme, therefore does not illustrate.The major radiator of the double-ring antenna described in the present embodiment is the bottom back of the body lid 2 of metal back cover, main antenna is provided with distributing point 5 and earth point 6, one antenna branch cabling is set from distributing point 5 to earth point, form outer ring antenna 7, outer ring antenna 7 can produce wider low-frequency resonant and part high-frequency resonant, what produce in the present embodiment is the resonance frequency of 1710-1990,2300-2700MHZ; Branch's cabling of a strip antenna is drawn again to PCB earth terminal 4 from distributing point 5, form inner antennas 8, inner antennas 8 can produce another high-frequency resonant, it is the high-frequency resonant of 1990-2300MHZ that the present embodiment produces frequency, and then draw a cabling from feed end and carry on the back to cover with bottom and be coupled, the effect of the return loss optimizing high-frequency resonant can be reached; Middle part can be carried on the back lid 3 by middle part back of the body lid 3 connection PCB earth terminal 4 to be coupled to be formed with main antenna and not have the resonance of radiation efficiency to minimize, avoid unnecessary impact.
Be illustrated in figure 3 the return loss plot of the present embodiment main antenna, all at-6dB once, absolute bandwidth has more than 1GHZ to HFS resonance S11 entirety.Low frequency part absolute bandwidth also has about 160MHZ nearly, and the bandwidth of antenna is done well in this environment.
As follows is the antenna radiation efficiency form of the present embodiment main antenna, the antenna radiation efficiency of the double-ring antenna shown in visible employing the utility model can up to high-frequency average 32%, low frequency is more than 25%, and traditional scheme generally can only accomplish high-frequency average 25% at rugged environment like this and the so wide situation of bandwidth requirement, low frequency average about 20%, whole efficiency will differ more than 5%.
In the utility model, the not concrete functional module introduced all can adopt ripe functional module of the prior art, such as key-press module, power module, LED backlight module, main control module etc.; Wherein main control module is existing microprocessor, and the control program wherein exported is common programs.
Be more than wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection range of the present utility model.
