Specific embodiment
Below with reference to the attached drawing of the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete
Whole description and discussion, it is clear that as described herein is only a part of example of the utility model, is not whole realities
Example, based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of protection of the utility model.
For the ease of the understanding to the utility model embodiment, make by taking specific embodiment as an example into one below in conjunction with attached drawing
The explanation of step, and each embodiment does not form the restriction to the utility model embodiment.
As shown in Figure 1, a kind of mobile terminal antenna of the metal shell based on switch is present embodiments provided, including antenna
One end of ontology 10, first switch 101 and second switch 102, first switch 101 and second switch 102 respectively with antenna body
The other end ground connection of 10 electrical connections, first switch 101 and second switch 103, antenna body 10 are also connect with a distributing point 103,
Distributing point 103 is located at one end of antenna body, and second switch 102 is between distributing point 103 and first switch 101.
The antenna body is as IFA Antenna Operations when second switch connects；When first switch connects and second switch
During disconnection, the antenna body is as Loop Antenna Operations；When first switch disconnects, the antenna body is as monopole antenna
Work.So as to preferably realize the covering of wide-band.
Antenna provided in this embodiment is by setting two be connected with antenna body switches to be adjusted and then to antenna
It is humorous, the adjustment to antenna different operating frequency range is realized, as long as applying different electric currents, you can motivate the humorous of different frequency range
It shakes, effectively extends the working frequency range coverage area of antenna.Increase first switch and second on antenna body using this
The antenna of switch form is easily extended the working frequency range of primary antenna, to increase the low frequency bandwidth to 699MHz-960MHz
Covering.And by the tuning of switch, realize intermediate-frequency band 1710-2170MHz and high-frequency band 2300-2400MHz, 2490-
The covering of 2690MHz.Wherein, the antenna body of the antenna can be arranged as required to for any appropriate shape, be not limited to attached
Linear type shown in Fig. 1 can also be arc or other suitable shapes.
Specifically, refering to what is shown in Fig. 2, for when second switch 102 is in connection status, operating frequency of antenna 800MHz
When antenna on current direction when, electric current flow direction be from the signal source 20s being connect with distributing point 103, followed by supreme
The other parts of second switch 102, first switch 101 and antenna body stated.Under such state, Antenna Operation part is formed
IFA antennas, first switch 101 can be attached or be disconnected to switch different states at this time, and then increase low frequency bandwidth,
Make the antenna that can work the signals of generation 699~960MHz frequency ranges.
