Problems solved by technology
[0005] Since a wireless communication device with multiple wireless communication protocols has multiple antennas, spatial isolation must be imposed between the antennas, which relatively increases the volume of the wireless communication device and is not conducive to miniaturization
On the other hand, the antenna and the corresponding signal processor need to be assembled with the system unit 15 through their own signal lines, so the antenna system cannot be simplified and is not conducive to the production and assembly of wireless communication devices.
In addition, the antennas will interfere and affect each other, for example, the wireless microwave signal received or transmitted by one antenna is blocked or interfered by another antenna, so the design is relatively more difficult
