In some embodiments, the metal frame 10 may also be located at the bottom of the smart phone and at the side near the top.
Fig. 2 is a schematic structural diagram of a metal frame antenna structure according to an embodiment of the present disclosure, please refer to fig. 2, in which a metal frame is divided into 5 metal segments 201, 202, 203, 204, and 205, an SPST (single pole single throw) switch is disposed between adjacent metal segments, that is, a switch 211 is disposed between the metal segment 201 and the metal segment 202, a switch 212 is disposed between the metal segment 202 and the metal segment 203, a switch 213 is disposed between the metal segment 203 and the metal segment 204, and a switch 214 is disposed between the metal segment 204 and the metal segment 205. The metal segment connected to the feed signal terminal 210 is a feed metal segment, and the antenna radiator includes the feed metal segment, that is, the antenna radiator includes the metal segment 201. It should be noted that, in the present application, the number of the divided sections of the metal frame is not limited, and the divided metal sections have a plurality of preset lengths for resonating out a plurality of frequency band bandwidths; the setting of the feed source metal segment is not limited, and the antenna radiator is connected with the feed source signal end.
The SPST switch has two on-off modes, and each SPST switch works independently and does not influence each other. When all the switches are switched off, the antenna radiator is the feed source metal section. When a switch arranged between the feed source metal segment and the metal segment adjacent to the feed source metal segment is conducted, the feed source metal segment and the adjacent metal segment are conducted metal segments, the rest metal segments are non-conducted metal segments, and the antenna radiator of the mobile terminal is the conducted metal segment. The length of the conducting metal section is larger than that of the feed source metal section, and the bandwidth of the resonant frequency band of the conducting metal section is smaller than that of the feed source metal section. The resonant frequency band of the antenna radiator ranges from 700MHZ to 2700 MHZ.
In the embodiment of the application, when the performance of the frequency band with the lowest frequency is to be realized, all the SPST switches are conducted, at this time, 5 metal segments are connected into a whole, the size of a radiator is longest, and the lowest frequency radiation can be realized; when the performance of the secondary low-frequency band is to be realized, the switch 211, the switch 212 and the switch 213 are turned on, the switch 214 is turned off, only the metal sections 201, 202, 203 and 204 participate in radiation, the size of a radiator is slightly short, and the secondary low-frequency radiation can be realized; by analogy, when the highest frequency band performance is to be achieved, all SPST switches are off and only metal segment 201 participates in radiation.
Optionally, in some implementation methods, an antenna radiator with a frequency of 54mm is required to implement 700Mhz, an antenna radiator with a frequency of 41mm is required to implement 900Mhz, an antenna radiator with a frequency of 21mm is required to implement 1800Mhz, an antenna radiator with a frequency of 18mm is required to implement 2100Mhz, and an antenna radiator with a frequency of 14mm is required to implement 2600 Mhz.

The preset length of the metal section is selected according to actual needs, and due to factors such as the environment of the whole machine and the design of a PCB (printed circuit board), the length of the metal section which resonates out the same frequency is uncertain. Because the frequency bands supported by the device in practical application are difficult to realize by metal segments with equal length, preferably, the length division of the metal segments is unequal.
Optionally, in this embodiment of the application, if the switch 211 is open, the antenna radiator is the metal segment 201, that is, the feed metal segment, no matter whether the remaining switches are closed or open; if the switch 211 is closed and the switch 212 is open, the on-off states of the switch 213 and the switch 214 do not affect the radiation bodies of the antenna to be the metal segment 201 and the metal segment 202; and analogizing in sequence, namely when the metal segment is conducted with the feed source metal segment, the metal segment can be used as a part of the antenna radiator to participate in radiation.
Optionally, in some implementation methods, the metal segment is connected to an antenna tuner, and the antenna tuner on the circuit may be used to widen a frequency band bandwidth resonated out by the metal segment. In the embodiment of the present application, the metal segment 201 is connected to the antenna tuner 221, the metal segment 202 is connected to the antenna tuner 222, and the metal segment 203 is connected to the antenna tuner 223; if the radiation of the 800Mhz-960Mhz frequency band is expected to be realized, the switch 211, the switch 212 and the switch 213 are closed, the switch 214 is opened, the metal segment 201, the metal segment 202, the metal segment 203 and the metal segment 204 participate in the radiation, and the antenna tuner 223, the antenna tuner 222 or the antenna tuner 221 is used for further expanding the frequency range realized by the metal segment to meet the requirement of the communication frequency band of the mobile terminal. The antenna tuners can be used individually or in combination of 2 or 3 antenna tuners, depending on the particular tuning effect requirements. The number of the antenna tuners is not limited in the present application, and is preferably 2 to 3. One antenna tuner can realize a plurality of matching states, wherein 4 states or 16 states are provided, and the like, and are also related to the selection of the antenna tuner. The position of the antenna tuner is determined according to the sensitive response position of the frequency band required to be expanded on the radiator.
The antenna tuner (tuner) is called antenna tuner for short and used between a transmitter and an antenna, during tuning, the microprocessor controls the analog-to-digital converter to quantize sampling parameters provided by the detection circuit into digital signals, then the digital signals are read into the memory, and the state change of the matching network is controlled after processing, so that impedance matching is realized. An antenna tuner is an impedance matching network that connects a transmitter to an antenna and enables impedance matching between the transmitter and the antenna, thereby maximizing the radiated power of the antenna at any frequency. The radio station is widely applied to ground, vehicle-mounted, ship-based and aviation short-wave radio stations. The antenna tuner is composed of a matching network, a detection circuit and a control circuit. The tuning range of a single antenna tuner is dependent on the specific antenna design, typically 30MHZ to 80 MHZ.

The length of the antenna radiator is determined by controlling the on-off state of the switch, so that the performance of different frequency bands is realized; the problems that the length and the size of the metal frame cannot be changed, and the performance loss is caused because the metal frame can only be limited by matching adjustment are solved; moreover, the design mode is flexible in debugging, the performance of a plurality of different frequency bands can be realized on the premise of not changing the design of the existing terminal, and the workload of debugging and designing is reduced. Therefore, the embodiment of the present application provides a switch control method, which controls a switch to be turned on or off according to a frequency band performance required to be implemented when a mobile terminal performs antenna debugging.
