Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
The utility model is further described in example.It should be appreciated that specific embodiment described herein is only used to explain this reality
With novel, it is not used to limit the utility model.
As shown in Figure 1, a kind of antenna structure, it is respectively used to emit, receives multiple frequency range radio signals including several
Antenna, the multiple match circuits for corresponding to lowest frequency antenna respectively and tuning switch, tuning switch are set as single pole multiple throw,
The feed point of the public termination lowest frequency antenna of tuning switch, the mating end of tuning switch are used to switch to corresponding match circuit.
Specifically, antenna includes low-frequency antenna 1 and medium-high frequency antenna 2, protected between medium-high frequency antenna 2 and low-frequency antenna 1
Holding prevents the isolation of mutual interference, and isolation is more than 15dB, in other embodiments, can also as the case may be split into antenna
Corresponding quantity；The radio signal of all senior middle school's low-frequency ranges is realized by the same antenna, since bandwidth requirement compares
Width is realized more difficult, it is difficult to reach requirement of the user to OTA performances for the antenna performance of single frequency range；In addition, it is full

Near, and it is distributed in the both sides of expansion slot 5；Mobile terminal 3 further includes radio-frequency antenna and PCB platelets 6, low-frequency antenna 1 with
And medium-high frequency antenna 2 connect radio frequency chip respectively after be connected to PCB platelets 6 with radio frequency cable respectively；Radio-frequency antenna is receiving nothing
During line electric signal, the radio signal of low-frequency range is transmitted to radio frequency day after low-frequency antenna 1 by low-frequency range antenna feed point 7
Line, transmitting signal process is conversely, the reception and transmitting and the receiving of low-frequency range radio signal of medium-high frequency section radio signal
And emission principle is identical.
Preferably, the side of expansion slot 5 offers USB9, and the middle part of the metal edge frame 4 positioned at mobile terminal 3,
The opposite side of USB9 offers loud speaker sound outlet hole 10；In order to mobile terminal 3 design aesthetics, by USB9, expansion slot 5 with
And loud speaker sound outlet hole 10 is reasonably distributed on metal edge frame 4, to prevent too tight of arranging on metal edge frame 4, influences to move
The appearance of dynamic terminal 3.
Use process：For radio-frequency antenna when receiving radio signal, the radio signal of low-frequency range is after low-frequency antenna 1
Radio-frequency antenna is transmitted to by low-frequency range antenna feed point 7, the radio signal of high band passes through middle height after medium-high frequency antenna 2
Band antenna feed point 8 is transmitted to radio-frequency antenna；It is on the contrary to emit signal process.
The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art
For member, under the premise of the application principle is not departed from, several improvements and modifications can also be made, these improvements and modifications also should
