In or equal to 2 integer.
It should be noted that a feeding point can correspond to one section of resonance frequency, antenna uses the resonance frequency in the frequency range
The radiation efficiency of rate receiving and transmitting signal is higher.
Optionally, the switch in the embodiment of the present invention includes at least M second end.
It should be noted that any one second end of the first end default connection of switch.
It is appreciated that the antenna in the embodiment of the present invention includes multiple feeds, each feed feed different in resonance arm
The frequency that point generates is different.
It should be noted that M above-mentioned feed can be identical or not identical, it is connected to the feedback of different feeding points
The resonance frequency of the output in source is different, and the present invention is not especially limit this.
Specifically, transceiver module, for connecting in the first end of switch and the first object end of switch, and determines that antenna is received
In the case that the frequency of the signal of hair is first frequency, first end and the first object end of control switch are disconnected, and control
The first end of switch is connect with the second target side of switch.

It should be noted that the feed work of the feeding point of transceiver module control switch connection different location, i.e. adjusting day
The length of line makes the length of antenna can be close to the antenna resonance length of each frequency (including low frequency, intermediate frequency and high frequency), because
This, the higher different resonance frequency receiving and transmitting signals of radiation efficiency can be used in antenna.
Antenna provided in an embodiment of the present invention, antenna include resonance arm, transceiver module, switch and M feed, transceiver module
It is connect with the first end of switch, each feed in M feed is connect with a second end of switch respectively, each feed difference
It is connect with a feeding point on resonance arm, transceiver module is connected in the first end of switch and the first object end of switch, is determined
In the case that the frequency of the signal of antenna transmitting-receiving is first frequency, first end and the first object end of control switch are disconnected,
And the first end of control switch is connect with the second target side of switch.That is, the transceiver module of antenna can be according to receiving and transmitting signal
Frequency, which determines, uses the corresponding resonance frequency of which feed, and the different ends of control switch, which can choose, connects different feeds,
And the different location feeding point that different feeds can connect, a feeding point can be corresponded to one compared with high radiation efficiency

Work can meet higher radiation efficiency；In turn, so that the terminal with the antenna is ok in the communication frequency of demand
There is good radiance, improves the ability of terminal receiving and transmitting signal.
Optionally, in conjunction with Fig. 1, as shown in Fig. 2, antenna 10 further include be connected to each feed 14 and each feeding point 15 it
Between matching module 16.
Specifically, matching module, for adjusting the resonance frequency for inputting the matching module.
For example, antenna is f in the corresponding resonance frequency of shows maximum radiation efficiency that a feeding point motivates, and feed is at this
The resonance frequency that feeding point motivates is f+ Δ f, then antenna can adjust what feed was motivated in the feeding point by matching module
Resonance frequency is f, so that the radiation efficiency of antenna receiving and transmitting signal at matching module resonance frequency f adjusted is maximum.
Optionally, matching module, for adjusting the corresponding impedance of resonance frequency for inputting the matching module.
For example, can be 50 Ω, impedance 50 by the corresponding impedance adjustment of the first resonance frequency for inputting the matching module
The reflection of the first resonance frequency is smaller in the case where Ω, can make radiation efficiency of the Antenna Operation in the first resonance frequency more
Greatly.
