1. A multiband printed antenna disposed on a circuit board which is positioned in an electronic device, the multiband printed antenna comprising:
a radiator arranged on an upper portion and one end of the circuit board, the radiator including a feed-in part, a first radiation part straightly extended rightward from an upper section of a first right edge of the feed-in part, and a second radiation part sequentially extended rightward, then extended upward, later extended leftward, and further extended downward from a lower section of the first right edge of the feed-in part, an extending path of the second radiation part being substantially formed in a P shape, the second radiation part being disposed around an outside of the feed-in part and an outside of the first radiation part; and
a grounding body arranged on a lower portion of the circuit board, the grounding body being positioned adjacent to a lower portion of a second right edge of the radiator, the grounding body being separated from the radiator, a first top edge of the grounding body being separated from a lower edge of the radiator by a first vertical distance, a first left edge of the grounding body being separated from the second right edge of the radiator by a first horizontal distance, the grounding body including a grounding part, a third radiation part extended rightward from a third right edge of the grounding part, and a fourth radiation part sequentially extended rightward, then extended downward and further extended leftward from a top end of a fourth right edge of the third radiation part, the fourth radiation part being formed in a lying U shape.
