In radio devices, the means for transmitting and receiving electromagnetic waves are called antennas, which convert a guided wave on a transmission line into an electromagnetic wave propagating in a medium, usually free space, and also into a guided wave propagating on the transmission line. All the information is transmitted by using electromagnetic waves, the operation of an antenna is required, for example, a common mobile terminal also uses an antenna to transmit information.
At present, in order to enable a mobile terminal to transmit and receive multi-band information, an antenna is usually added to the mobile terminal to cover the added frequency band, or a new resonance is generated by increasing the size of the antenna or adding a PCB (Printed Circuit Board) or LDS (Laser-Direct-structuring) routing; however, since the space of the existing mobile terminal is small, it is basically difficult to realize multi-band information communication by increasing the number of antennas; however, increasing the size of the antenna and increasing the PCB or LDS traces also result in wasted space, and especially for the lower frequency bands, the LDS trace has problems of insufficient bandwidth and low communication efficiency due to lack of headroom.

The position of the antenna radiator may be arranged according to actual use conditions, and in this embodiment, the position of the antenna radiator is not limited.
In a specific implementation, the middle frame is made of a metal material and can be used as a reference ground of an antenna system, in order to enable electromagnetic waves of current distributed on the surface of an antenna radiator to radiate to a space when an antenna works, the antenna radiator needs to be separated from the reference ground, and as shown in fig. 1, the antenna radiator and the middle frame are separated by an antenna broken seam 103 on two sides of a metal frame where the antenna radiator is located; in order to provide a ground path for the current on the antenna radiator, in the present embodiment, the antenna radiator is connected to the middle frame by a metal connector 106; further, an antenna slot 105 is disposed between the antenna radiator and the middle frame of the mobile terminal, as shown in fig. 1, two opposite sides of the mobile terminal are respectively provided with an antenna slot 105, which is generally in a straight slot form or a C-shaped form, and the antenna slot is filled with a non-metallic material. The number of antenna slot slots may be arranged on the mobile terminal according to actual needs, and in this embodiment, the number of antenna slot slots is not limited.
In this embodiment, the antenna slot is selected as a straight slot, and when in actual use, an antenna unit is disposed in the antenna slot near one end of the antenna radiator, and no antenna unit is disposed in the other antenna slot; the antenna unit comprises an additional antenna branch and a lumped branch which are connected with an antenna radiator and a middle frame, wherein the additional antenna branch has the function of controlling the resonant frequency and the bandwidth of the antenna, and the lumped branch can form a band-pass filter to generate new resonance; when the mobile terminal is used specifically, when the mobile terminal runs, the antenna unit can generate a plurality of different resonances in the area corresponding to the antenna slot through the metal connecting piece and the slot structure, and each resonance can receive or transmit electromagnetic waves of different frequency bands, so that the mobile terminal can communicate in multiple frequency bands.
According to the mobile terminal provided by the embodiment of the invention, the antenna system of the mobile terminal comprises an antenna radiator and an antenna unit; the antenna radiator is arranged on a metal frame of the mobile terminal, and an antenna broken joint is arranged between the metal frame where the antenna radiator is arranged and other metal frames; an antenna slotted gap is formed between the antenna radiator and a middle frame of the mobile terminal; the antenna radiator is connected with the middle frame through a metal connecting piece; the antenna unit is arranged between the antenna slotted slots, a slotted structure is further arranged on the middle frame corresponding to the antenna unit, and the antenna unit comprises an additional antenna branch and a lumped branch which are connected with the antenna radiator and the middle frame; when the mobile terminal operates, the antenna unit generates a plurality of resonances in the area corresponding to the antenna slot through the metal connecting piece and the slot structure, so that the mobile terminal can communicate in multiple frequency bands; the mobile terminal can realize multi-band communication, thereby improving the communication efficiency of the mobile terminal.
In practical applications, the antenna unit is disposed in a resonance region surrounded by the antenna radiator, the metal connecting member, the middle frame, and the metal bezel, so as to generate multiple resonances in the resonance region.
Specifically, the metal connector connects the antenna radiator and the middle frame serving as a reference ground of the antenna system, so as to provide a return path for a current on the antenna radiator, and a resonance area capable of generating a plurality of different resonances is formed on the antenna unit, the antenna radiator, the metal connector, the middle frame and a metal frame of the mobile terminal at one end of the antenna unit, so as to generate resonances in the resonance area, thereby realizing multi-band communication of the mobile terminal.
Further, fig. 2 shows a schematic structural diagram of another mobile terminal, and as shown in fig. 2, the antenna unit includes an antenna feeding point 201 and a matching circuit 202 connected to the antenna feeding point, the antenna feeding point is connected to the middle frame, and the matching circuit is further connected to the antenna radiator.
In a specific use, in order to extract a signal of a mobile terminal to generally provide an antenna feeding point, as shown in fig. 2, the number of the antenna feeding points 201 is 1, and the antenna feeding point is connected between an antenna radiator and a middle frame, and in an actual use, in order to match an impedance between the antenna radiator and the antenna feeding point, a matching circuit may be provided between the antenna radiator and the antenna feeding point, and the matching circuit is generally a T-type matching circuit or a pi-type matching circuit formed by superimposing L-type matching circuitsCan be prepared byThe impedance matching circuit is used for matching the impedance of the antenna feed point and the impedance of the antenna radiator to a certain intermediate impedance, so as to complete the impedance matching from the source to the load.
As shown in fig. 2, the additional antenna branch 108 is connected to the connection path between the antenna feeding point and the matching circuit; the additional antenna branch is a PCB (printed circuit board) line or an LDS (laser direct structuring) line.
Generally, the PCB trace is a support for electronic components, is a carrier for electrical connection of electronic components, and is also called a "printed circuit board" because it is manufactured by electronic printing; the LDS wiring is a metal antenna formed by directly plating a molded plastic bracket by using a laser technology; the PCB wiring or the LDS wiring can generate resonance, and the resonant frequency and bandwidth of the antenna can be adjusted by adjusting the length of the LDS wiring or the shape of the PCB wiring, so that the communication of the mobile terminal in the frequency band can be controlled.
Further, the lumped elements included in the lumped branches are inductors and/or capacitors, where in the antenna unit shown in fig. 2, the lumped elements included in the lumped branches are taken as the inductors and the capacitors for example.
Specifically, as shown in fig. 2, one end of the lumped branch is connected to the antenna radiator, the other end of the lumped branch is connected to the middle frame, and the lumped branch includes an inductor L and a capacitor C, the inductor and the capacitor are connected in series between the middle frame and the antenna radiator, the inductor and the capacitor connected in series may form a band pass filter, the antenna radiator, the metal connector, and a frame of the middle frame may generate a resonance, and a frequency of the resonance may be adjusted by adjusting positions and sizes of the capacitor and the inductor, so as to control the mobile terminal to communicate in the frequency band.
In practical use, in order to increase the current path of the antenna unit, the lumped branches and the matching circuit included in the antenna unit may be connected. Specifically, as shown in fig. 2, the lumped branches and the paths with matching circuits described above are connected by the connection lines 206, so that the paths through which the currents flow are increased. In practical use, if the current path of the antenna unit does not need to be increased, the lumped branch and the matching circuit do not need to be connected by a connecting wire.
Usually, a middle frame corresponding to the antenna unit is further provided with a slotted structure, and the slotted structure is communicated with an antenna slotted gap; when the mobile terminal operates, the antenna unit generates four resonances in the area corresponding to the slot structure and the slot of the antenna.
As shown in fig. 2, the slot structure 107 and the antenna slot 105 are communicated with each other, and when the mobile terminal operates, the antenna unit may generate a plurality of resonances in the areas of the slot structure and the antenna slot.
For ease of understanding, fig. 3 shows a structural diagram of a resonance distribution, as shown in fig. 3, based on the antenna unit of the mobile terminal shown in fig. 2, four resonances may be generated, specifically, as shown by a dotted line in fig. 3, the additional antenna branch is an LDS trace, which may generate a resonance 4; the band-pass filter can generate a resonance 3, and the resonance 3 is in a resonance area surrounded by the antenna radiator, the lumped branch, the metal connecting piece and the metal frame of the middle frame; generating resonance 1 in a resonance area surrounded by the slotted structure, the antenna slotted slot and the antenna broken slot; because the antenna radiator and the middle frame side frame close to the antenna unit have stronger currents, resonance 2 is generated in a resonance area surrounded by the antenna radiator, the middle frame side frame and a passage where an antenna feed point is located; therefore, when the mobile terminal works, the antenna unit can respectively generate four resonances with different frequencies, namely the resonance 1, the resonance 2, the resonance 3 and the resonance 4, in the area corresponding to the slotted structure and the slotted slot of the antenna, so that the mobile terminal can realize multi-band communication, and further the communication efficiency of the mobile terminal is improved.
Further, the resonance distribution of each resonance is clear, and each resonance can be conveniently tuned, for example, the frequency of the resonance 4 is mainly controlled by the length of the LDS wiring, and in actual application, the frequency of the resonance 4 can be adjusted by adjusting the length of the LDS wiring; the frequencies of the resonances 1, 2 and 3 can be adjusted by adjusting the lengths of the antenna radiator and the slotted structure; the frequency of the resonance 2 and the resonance 3 can be adjusted by adjusting the positions and the sizes of the capacitor and the inductor; through the adjustment of the resonance, the control of the multi-band communication of the mobile terminal can be realized.
In a specific implementation, the antenna System can be set as a GPS (Global Positioning System)/WiFi (Wireless broadband) antenna structure, and the GPS/WiFi antenna structure has a better standing wave after adjusting various parameters such as the lengths of the antenna radiator and the slot structure, the positions and sizes of the capacitor and the inductor, and the length of the LDS routing. For ease of understanding, fig. 4 shows a graphical representation of an antenna reflection coefficient parameter, and as shown in fig. 4, the GPS/WiFi antenna structure has five very good standing waves in the GPS L5, GPS L1, wiFi 2.4G and WiFi 5G frequency bands, respectively. Two resonances appear in the WiFi 5G frequency band, one of which is generated by the LDS trace and the other is a higher order mode generated by the middle frame, so that when the antenna size is appropriate, the WiFi 5G resonance can be generated without increasing the LDS trace. As shown in fig. 4, the reflection coefficient parameters corresponding to the four frequency bands are all below-15 dB, so that the bandwidth of the GPS/WiFi antenna structure can meet the use requirement, and meanwhile, the antenna performance under each frequency band is also ideal under the condition that the overall size of the antenna is small.
The second embodiment:
an embodiment of the present invention further provides a resonance method of an antenna system, and fig. 5 shows a flowchart of the resonance method of the antenna system, where the method is applied to the mobile terminal, and includes the following steps:
step S502, monitoring the current network environment of the mobile terminal;
step S504, according to the network environment, triggering the antenna system of the mobile terminal to generate a plurality of resonances in the area corresponding to the antenna slot, so that the mobile terminal can communicate in multiple frequency bands.
In specific implementation, if the frequency band which can enable the current mobile terminal to communicate is monitored to exist in the network environment where the current mobile terminal is located, the current mobile terminal triggers the antenna system to generate a plurality of resonances in the area corresponding to the antenna slotted gap according to the located network environment, and the resonances matched with the communication frequency band of the located network environment are utilized to communicate with external communication equipment; for example, if the antenna system of the current mobile terminal can generate four resonances of different frequency bands, namely, resonance 1, resonance 2, resonance 3, and resonance 4, in an area corresponding to an antenna slot, but only resonance 1 and resonance 3 are matched with a communication frequency band in a network environment where the current mobile terminal is located, the current mobile terminal can only communicate with an external communication device by using generated resonance 1 and resonance 3.
