Antenna, earthing block and reinforcing plate constitute different antennas, and the width of earthing block determines the isolation between each antenna.With end
End has mutiple antennas, but the relatively low prior art of isolation is compared between mutiple antennas, the width of each earthing block in the present invention
Degree is determined without the isolation between breakpoint metal frame annular multiple antennas, so nothing can be adjusted by the width of regulated ground block
Isolation between breakpoint metal frame annular multiple antennas, so as to improve no breakpoint metal frame ring by the width of regulated ground block
Isolation between shape multiple antennas, and then improve the quality that terminal communicates.The present invention is by adjusting the perimeter of loop checking installation
Come adjust antenna covering frequency range resonant frequency, by the position of regulated ground block and antenna feed point come adjust antenna cover
The bandwidth of frequency range so as to change the frequency range that antenna is covered, that is, changes the frequency range that antenna is covered.
