The utility model discloses a 4G whole network built-in FPCB antenna applied to a code-scanning payment terminal, comprising an FPCB substrate, namely an antenna radiator on the FPCB substrate, the antenna radiator is provided with an L-shaped gap, and a first radiation area and a second radiation area which are divided by the L-shaped gap, the second radiation area semi-surrounds the first radiation area, and the first radiation area and the second radiation area are separated by the L-shaped gap. The first radiation area and the second radiation area are communicated through a connector at the free end of the long edge of the L-shaped slot, the short edge of the L-shaped slot extends out of the antenna radiator and separates the first radiation area from the second radiation area, a second slot perpendicular to the short edge of the corresponding L-shaped slot is formed in the first radiation area, and the second slot is communicated with the L-shaped slot. One side of the free end,deviating from the short
