That is, in the embodiment of the present application, the DG section of the second antenna radiator is configured to radiate a radio frequency signal in the gps_l5 frequency band, and the DF section of the second antenna radiator is configured to radiate a radio frequency signal in the wifi_5g frequency band.
In the embodiment of the application, the second antenna radiator (DG section of the metal frame) is a radiation structure of the antenna 2 and the antenna 3, the antenna 2 includes a DF section of the metal frame, a second feeding point, a second matching circuit and a second feed source, and the antenna 3 includes a DG section of the metal frame, a third feeding point, a third matching circuit and a third feed source. Two 1/4 wavelength fundamental mode current paths DF and DG are excited by feeding at E and F, wherein the DF corresponds to the WIFI_5G frequency band, the DG corresponds to the GPS_L5 frequency band, namely the WIFI_5G frequency band is realized by the antenna 2, and the GPS_L5 frequency band is realized by the antenna 3.
According to the antenna structure provided by the embodiment of the application, the coverage of the GPS_L1 frequency band and the WIFI_2.4G frequency band is realized through the antenna 1, the coverage of the WIFI_5G frequency band is realized through the antenna 2, the coverage of the GPS_L5 frequency band is realized through the antenna 3, and the coverage of the GPS_L1, the WIFI_2.4G and the WIFI_5G frequency band can be realized through coexistence of the three antennas. In addition, the resonance of the working frequency bands of the three antennas is 1/4 wavelength fundamental mode radiation in the metal frame fracture environment, and the radiation efficiency can be optimized.
Optionally, the first matching circuit is a low-pass high-resistance filter circuit, the second matching circuit is a low-resistance high-pass filter circuit, and the third matching circuit is a low-pass high-resistance filter circuit.
In the embodiment of the application, the antenna 1 and the antenna 2 share the fracture, and the current excited by each antenna is isolated and coupled to the feed source of the other party through the fracture so as to solve the isolation problem. Because the antenna 1 realizes the GPS_L1 and the WIFI_2.4G frequency bands, the Ant2 realizes the WIFI_5G frequency band, and the interval between the two frequency bands is relatively large from the aspect of frequency, the problem of isolation between the two antennas can be solved by adopting low-pass high-resistance filter network matching for the antenna 1 and low-resistance high-pass filter matching for the antenna 2.

In addition, the first matching circuit may have the same structure as the third matching circuit.
Since the antenna 2 has a high operating frequency, a shorter antenna radiating structure is required, whereas the antenna 3 has a low operating frequency, a longer antenna radiating structure is required. The antenna 3 is tuned by connecting the large capacitor C1 in series with the large inductor L1, the large capacitor C1 in parallel is equivalently and directly connected to the ground at high frequency for the antenna 2, the large inductor L1 in series is equivalently and directly connected to the ground at high frequency, namely, the antenna 2 is grounded at the feed position of the antenna 3, so that the radiation structure of the antenna 2 is limited in the DF section, the shorter radiation structure required by the corresponding WIFI_5G antenna can be well kept at good isolation with the antenna 3. The parallel inductor L2 at the antenna 2 tunes impedance, and the series small capacitor C2 is connected with low frequency, so that the isolation between the antenna 1 and the GPS_L1 and the WIFI_2.4G is good, and the isolation between the antenna 1 and the antenna 3 at the L5 can be kept good. Therefore, the high resistance of the antenna 2 to the antenna 3 can not influence the current distribution which is excited by the antenna 3 and is distributed on the DG section, and the requirement of a longer radiation structure which is required by the low-frequency resonance of the antenna 3 can be met.
Meanwhile, the current of the frequency of GPS_L1& WIFI_2.4G excited by the antenna 3 is blocked by the low-resistance filter network of the antenna 2, and the current of the section GPS_L5 excited by the antenna 1 is blocked by the low-resistance filter network of the antenna 2, so that the antenna 1 and the antenna 3 can also keep good isolation. According to the antenna structure provided by the embodiment of the application, the isolation degree between the three antennas can be kept below-14 dB, so that the three antennas have higher system efficiency.
According to the embodiment of the application, three antennas are integrated in a limited space, and the isolation between the antennas can be well solved by reasonably distributing the three antennas and combining a matching circuit.
In addition, in the embodiment of the application, the performance of the antenna 3 can be effectively improved by lengthening the DG length, and the performance reaches the limit when the DG length is close to 1/4 wavelength corresponding to resonance of the DG. Due to the coupling influence of the antenna matching loading and the whole structure environment, the performance of the antenna 3 can be optimized when the DG section is more than 18mm, the radiation structure is reduced due to the reduction of the DG length, and the performance of the antenna 3 can be reduced, but the antenna environment is good, and the performance of the antenna is also more advantageous than that of other schemes.
According to the antenna structure provided by the embodiment of the application, the metal frame is divided into the first antenna radiator and the second antenna radiator through the fracture of the metal frame, the first positioning frequency band signal and the first local area network communication frequency band signal are transmitted through the first antenna radiator, the second positioning frequency band signal and the second local area network communication frequency band signal are transmitted through the second antenna radiator, the coverage of the GPS dual-frequency band and the local area network communication frequency band is realized in a limited space, the antenna coexistence problem is avoided, and the antenna has better performance.
