Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.Wherein identical parts adopt identical Reference numeral.
See also shown in Fig. 3-5, antenna for mobile phone of the present utility model comprises unipole antenna, and described unipole antenna comprises sheet metal 1 and from described sheet metal 1 extended feed side 2, described antenna for mobile phone also comprises from described sheet metal 1 extended earth terminal 3.Setting by earth terminal 3 improves the impedance matching of antenna and transmission line, thereby reduces VSWR, promotes antenna efficiency.
See also Fig. 3, Fig. 4 and shown in Figure 5, in specific embodiment of the utility model, described feed side 2 and described earth terminal 3 all extend from the edge of described sheet metal 1.Described earth terminal 3 is near described feed side 2.Described earth terminal 3 be arranged in parallel with described feed side 2.
Can the impedance matching of antenna and transmission line be improved by suitably adjusting the relative position of this earth terminal 3 in antenna.For example can change the antenna characteristics impedance and reach impedance matching by adjusting earth terminal 3 and feed side 2 middle ware distances.In specific embodiment of the utility model, the spacing at described earth terminal 3 centers and 2 centers, described feed side is 3-5mm.Perhaps necessity be arranged in parallel according to above-mentioned, can also change characteristic impedance and reach impedance matching, as shown in Figure 7 by changing the relative position of earth terminal 3 and described feed side 2.
Preferably, offer at least one slotted eye 4 in the described sheet metal 1.More preferably, the number of described slotted eye 4 be 2 or more than, described slotted eye 4 width differ.Extend described feed side 2 described sheet metal 1 a part 5 and extend between another part 6 of described sheet metal 1 of described earth terminal 3 by described slotted eye 4 partial divisions and open.The type of described slotted eye 4 comprises one or more of L shaped slotted eye, circular slotted eye, square slotted eye and triangle slotted eye.Obviously, described slotted eye 4 slotted eye that can also be other shape.As long as it can make the capacitive reactance of antenna increase, offset the induction reactance that the part feed-in causes, thereby improve the impedance operator of antenna, make the bandwidth of antenna further get a promotion.
See also shown in Figure 3, in specific embodiment of the utility model, the number of described slotted eye 4 is 2, one of them slotted eye 4 is L shaped slotted eye, another slotted eye 4 is the combination of L shaped slotted eye and rectangle slotted eye, extends the part 5 of described sheet metal 1 of described feed side 2 and the combination partial division that to extend between another part 6 of described sheet metal 1 of described earth terminal 3 be described L shaped slotted eye and rectangle slotted eye by described another slotted eye 4 and opens.
