Referring to fig. 1, an embodiment of the present application provides a mobile terminal device 100.
The mobile terminal device 100 comprises a front housing 101 and a rear housing 102. The front case 101 may include a protective cover 21, a display 22, and the like. The front housing 101 and the rear housing 102 together enclose a receiving space for receiving other components, such as a camera assembly, a circuit board, a battery, a diversity antenna and parasitic antenna assembly 23, a main diversity antenna distribution area 24, a diversity antenna distribution area 25, and the like.
In some embodiments, the front case 101 and the rear case 102 may be metal cases.

The protective cover 21 may include a display area and a non-display area. The display area is transparent and corresponds to the light emitting surface of the display screen 22. The non-display area is non-transparent to shield the internal structure of the electronic device 100. The non-display area can be provided with holes for transmitting sound and light.

Referring to fig. 2, the electronic device 100 may have an earphone hole 105, a microphone hole 106, a usb interface hole 107, and a speaker hole 108 formed at a periphery thereof. The earphone hole 105, the microphone hole 106, the speaker hole 108, and the usb interface hole 107 are all through holes.

The shape of the diversity antenna 231 is a rectangle lacking one side, the lacking one side of the rectangle has two adjacent sides, one of the adjacent sides is called a first adjacent side, the other adjacent side is called a second adjacent side, the second adjacent side is longer than the first adjacent side, the routing design of the diversity antenna 231 preferentially meets the requirements of each frequency band of the SISO channel mode, so that the performance of each diversity antenna 231 reaches a good index, for example, the routing form of the diversity antenna 231 adopts an IFA antenna form, a loop antenna form and the like. The parasitic antenna 232 is in the shape of a long line, for example, a long straight line, a long curved line, a long broken line, etc., and is made of one or a combination of a plurality of materials, such as an FPC antenna, an LDC antenna, and a steel sheet antenna.

The load 234 may be a ground inductor, a ground capacitor, a ground wire or a neutral wire, etc. If the mobile terminal uses MIMO channel to transmit and receive data during remote communication, the mobile terminal needs to place the antenna in the MIMO structure, so that the mobile terminal can receive data information with larger capacity, but when the mobile terminal uses MIMO channel to transmit and receive data, radiation is generated between the diversity antennas 231 and the main set antenna, so that coupling occurs between the diversity antennas 231 and the main set antenna in the same frequency band or a similar frequency band, so that mutual interference between the antennas can affect the throughput of the mobile terminal antenna to transmit and receive data, at this time, the switch 233 is closed, so that the parasitic antenna 232 is connected with the load 234 through the switch 233, the load 234 carries negative current, then the parasitic antenna 232 can conduct negative current, so that the parasitic antenna 232 can carry negative electrons, and radiation generated by the diversity antennas 231 and the main set antenna is positive electrons, then, the negative electrons carried by the parasitic antenna 232 can cancel the positrons generated by the radiation of the diversity antenna 231 and the main set antenna, so as to reduce the radiation range of the diversity antenna 231 and the main set antenna, and finally, the coupling between the diversity antenna 231 and the main set antenna in the same frequency band or the similar frequency band is reduced, the mutual interference between the antennas is reduced, and the throughput of the mobile terminal antenna for receiving and transmitting data is improved. If the mobile terminal is in remote communication and uses the SISO channel to receive and transmit data, the mobile terminal needs to place the antenna in the SISO structure, so that the quality of the data information received and transmitted by the mobile terminal is higher, and the situations of data packet loss, data transmission interruption and the like are avoided.
