Detailed description of the invention
Fig. 1 is the stacking schematic diagram that a kind of antenna for increasing bandwidth of the present invention is installed to mobile terminal.
Fig. 2 is a kind of schematic diagram for the antenna for increasing bandwidth of the present invention.
Specific embodiment
The present invention is further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figure 1 to Figure 2, a kind of antenna increasing bandwidth, is arranged in assist side 5, including feeding point F and short dot The central area of the wiring board 5 is arranged in S, the feeding point F, and the marginal zone of the wiring board 5 is arranged in the short dot S Domain, framework, can provide the frequency range of broader 2G, 3G and 4G in the case where not using tuning switch by above-mentioned design Covering.
As shown in Figure 1 to Figure 2, positive and negative 1/6th route in width midpoint of the wiring board 5 is arranged in the feeding point F In plate length range.
As shown in Figure 1 to Figure 2,1/6th wiring boards that the short dot S is arranged in apart from 5 edge of wiring board are long It spends in range.
As shown in Figure 1 to Figure 2, the feeding point F is connect by connecting metal strip 14 with the short dot S.
As shown in Figure 1 to Figure 2, the connection metal strip 14 rises close to one end of the feeding point F equipped with antenna resonance Point G1, the antenna resonance starting point G1 are connected separately with the first radiator 11 and the second radiator 12, and the short dot S is connected with Third radiator 13, wherein first radiator 11 is left frame shape, and second radiator 12 is right frame shape, described Third radiator 13 is inverted L shape, and the path end of first radiator 11 is W1, and the path of second radiator 12 is tied Shu Duanwei W2, the path starting end of the third radiator 13 are G2, and first radiator 11 is long branch, second spoke Beam 12 and third radiator 13 are then short branch.
As shown in Figure 1 to Figure 2, the length of first radiator 11 is the quarter-wave resonance road of Frequency Diameter, the length of second radiator 12 are the quarter-wave resonance path of IF frequency, the third radiator 13 Length is the quarter-wave resonance path of higher frequency.
As shown in Figure 1 to Figure 2, under different day space of lines and device configurations, the length of second radiator 12 Can be preferably the quarter-wave resonance path of higher frequency, the length of the third radiator 13 be then preferably in again and again The quarter-wave resonance path of rate.
As shown in Figure 1 to Figure 2, the path of the path end W1 of first radiator 11 and second radiator 12 End W2 is corresponding, and the left side of the first radiator 11 is then arranged in third radiator 13 depending on the position of feeding point F and short dot S Or right side.
As shown in Figure 1 to Figure 2, the path of first radiator 11 terminates the road of extreme direction Yu the third radiator 13 Diameter end is contrary, i.e. the path of the first radiator 11 terminates extreme direction to the right, then the path knot of third radiator 13 Then to the left, vice versa for beam extreme direction.
As shown in Figure 1 to Figure 2, the path of the path end W1 of first radiator 11 and second radiator 12 Gap is equipped between end W2, first radiator 11 forms coupling, the third with second radiator 12 Clearance D, the third radiator 13 and 11 shape of the first radiator are equipped between radiator 13 and first radiator 11 At coupling.
