In the above embodiment, the first antenna 101 and the fourth antenna 104 are respectively located at the top and the bottom of the metal frame 1, and both can receive low-frequency signals, and the top and the bottom of the metal frame 1 are far away from other components of the communication device, so that the communication environment is relatively good, and the communication quality of a low-frequency band can be ensured; meanwhile, the fifth antenna 105 and the sixth antenna 106 are both located at the left part of the metal frame 1 and can transmit signals, and the eighth antenna 108 and the fourth antenna 104 which transmit signals are located at the bottom and the top of the metal frame 1 respectively, that is, the main set antennas of the four frequency bands of low frequency, intermediate frequency, high frequency and ultrahigh frequency are concentrated in the right side area of the metal frame 1, so that the distances from the radio frequency chip to the main set antennas of the four frequency bands are relatively close, and compared with a scheme that the main set antennas of each frequency band are scattered in different areas of the metal frame 1, the path loss of the signals is reduced (the path loss is about 1dB), and the communication quality corresponding to the fifth antenna 105, the sixth antenna 106, the eighth antenna 108 and the fourth antenna 104 is improved.

The fifth metal segment 405 includes a third sub-metal segment 503 adjacent to the fourth metal segment 404 and a fourth sub-metal segment 504 adjacent to the sixth metal segment 406, the fourth sub-metal segment 504 is integrated into the fourth antenna 104, the fourth antenna 104 is a combined antenna of a loop antenna and a parasitic antenna, a transverse portion of the fourth sub-metal segment 504 is 5mm in length and forms a loop antenna, and a longitudinal portion of the fourth sub-metal segment is 10mm in length and forms a parasitic antenna. The length of the fourth sub-metal segment 504 (i.e. the distance between the antenna feed point and the ground point) is 38mm, the distance between the antenna feed point and the antenna switch is 16mm, and the matching circuit of the fourth antenna 104 is: a series 1pF capacitor is connected from the antenna terminal and the matching circuit brings the low frequency point from the first quadrant towards the centre of the smith chart. Similarly, the fourth antenna 104 adopts the antenna switch to connect different inductance grounds in parallel to switch different low frequency bands, thereby realizing 617-960MHz full coverage, specifically, when the antenna switch is switched to the 68nH inductor, the low frequency of the fourth antenna 104 falls to 600 MHz; when the antenna switch is switched to the 47nH inductance, the low frequency of the fourth antenna 104 falls at 700 MHz; when the antenna switch is switched to the 15nH inductance, the low frequency of the fourth antenna 104 falls at 800 MHz; when the antenna switch is switched to the 4.7nH inductance, the low frequency of the fourth antenna 104 falls at 900 MHz. The free space efficiency of the fourth antenna 104 is-6.5 dB at the peak of the low frequency, and since the fourth antenna 104 is located at the top of the metal frame 1, the fourth antenna 104 is relatively less affected by the head, and therefore the performance in the head-hand mode is better.
