Specifically, the frequency of the Low frequency Band is 824-960MHz, and the frequency of the middle frequency Band is 1.71-2.17 GHz; the high frequency band HighBand is between 2.3 and 2.69 GHz. With reference to fig. 1, when the first radiation portion 32, the second radiation portion 31 and the third radiation portion 33 are specifically disposed, the third radiation portion 33 and the second radiation portion 31 are respectively located at two sides of the feeding unit, and the first radiation portion 32 is connected to the third radiation portion 33.
With continued reference to fig. 1, the second antenna 40 is a 5G antenna, and when the second antenna 40 is specifically arranged, the second antenna 40 is arranged on the top of the middle frame 10 and located at the middle position of the support, and the form of the second antenna 40 is IFA + Loop. The specific structure of the second antenna 40 includes: a second feeding unit 41 and a second radiating unit connected to the second feeding unit 41; the second antenna 40 further includes a ground line connected to the ground of the PCB to form a ground, and the second feeding unit 41 is connected to the feeding point Feed. The second radiation unit includes a seventh radiation portion 43 and an eighth radiation portion 42; the seventh radiation portion 43 and the eighth radiation portion 42 are arranged on both sides of the second feeding unit 41. The seventh radiation portion 43 and the eighth radiation portion 42 correspond to different operating frequency bands of the second antenna 40, respectively, and thus can correspond to different frequency bands. Frequency bands n78(3.3-3.8GHz) and n79(4.4-5GHz) as included by the second antenna 40; the seventh radiation portion 43 corresponds to n78, and the eighth radiation portion 42 corresponds to n 9.
With continued reference to fig. 1, the third antenna 50 is a triple antenna, and the third antenna 50 is disposed on the upper right end of the bracket. The third antenna 50 is in the form of an IFA, which comprises in particular: a third feeding unit 51 and a third radiating unit connected to the third feeding unit 51, wherein the third antenna 50 further includes a ground line, and the ground line is connected to the ground of the printed circuit board 20 to form a ground. The third feeding unit 51 is connected to a feeding point Feed. The third radiation unit includes: a fourth radiation portion 51, a fifth radiation portion 52, and a sixth radiation portion 53; as shown in fig. 1, the fourth radiation portion 51, the fifth radiation portion 52 and the sixth radiation portion 53 are arranged in a single row, and the fifth radiation portion 52 is located between the fourth radiation portion 51 and the sixth radiation portion 53. When in use, the fourth radiation portion 51 corresponds to the first working frequency band of the third antenna 50; the fifth radiation part 52 corresponds to the second working frequency band of the third antenna 50; the sixth radiation portion 53 corresponds to a third operating frequency band of the third antenna 50; and the first working frequency band is smaller than the second working frequency band and smaller than the third working frequency band.

Further, the first antenna 30 and the third antenna 50 are generally placed on both sides of the top end (bottom end): the first antenna 30 is a low frequency (LOOP antenna full frequency band), the third antenna 50 is a gps (wifi), and these two antennas should ensure radiation performance, and at the same time, ensure isolation between the antennas and cannot be coupled to each other. Since the high frequency and the harmonic of the first antenna 30 may affect the GPS and WIFI of the third antenna 50, the second antenna 40 is disposed between the first antenna 30 and the third antenna 50, and since the second antenna 40 is a 5G antenna and the frequency of the 5G antenna is ultra-high and ultra-short, the length of the wavelength of the working frequency band of the second antenna 40 is smaller than the length of the wavelength of the working frequency band of the first antenna 30 and the length of the wavelength of the working frequency band of the third antenna 50. So that the first antenna 30 and the third antenna 50 are not interfered, and in addition, the isolation between the first antenna 30 and the third antenna 50 can be increased by the addition of the second antenna 40. By adopting the layout, the clearance between the antennas is improved, and the communication effect of the mobile terminal is further improved.
The embodiment of the application also provides a mobile terminal, which comprises a shell and the antenna assembly, wherein the support, the first antenna, the second antenna and the third antenna are arranged in the shell. For specific description, referring to fig. 1, in the above technical solution, three antennas are supported by using a support, and when the three antennas are arranged, the antenna with the shortest wavelength is arranged in the middle, and because the antenna frequency of the second antenna is ultra-short in wavelength, the antenna space occupied by the antenna array is relatively small, and the first antenna and the third antenna are not interfered or interfered, and the requirement of the isolation between the first antenna and the third antenna can be ensured.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
