Antenna strip Introduction: When using a metal middle frame, the signal conduction will be affected. After optimization, most models have turned the metal middle frame into a part of the antenna. Different antennas have different functions. The antenna belt is the breakpoint of different antennas. For phones, the antenna is integrated into the middle frame and there is no antenna band.
Principle: Electromagnetism in a sealed metal space cannot be conducted. Signal is an expression of magnetic induction. If a phone with a metal body is not designed with an antenna band, the phone will be in a state of very poor signal for a long time and the metal shielding will completely block the signal of the mobile phone in the phone shell.
