Embodiment

For describing technology contents of the present utility model, structural feature, the purpose of being reached and effect in detail, below exemplify embodiment now and conjunction with figs. is described in detail.

See also Fig. 1, the utility model antenna 100 is around coated, comprises the main part 11 of a bar shaped of extending up and down, and the middle part of this main part 11 is extended with a high-frequency radiation part 12 around shape.This high-frequency radiation part 12 has first extension 121 of a bar shaped that extends back from the posterior lateral margin middle part of main part 11, the arc bending left of the end of first extension 121 also continues to have extended to form one second extension 122 left, and the tip forward arc bending of this second extension 122 also continues to have extended to form forward one the 3rd extension 123.The lower end of described main part 11 bends the feeding portion 13 that extends downwards after being extended with an extension left again, and the upper end of main part 11 is extended with the low frequency radiation portion 14 of a tortuous extension.

Described low frequency radiation portion 14 has one from the first consistent Department of Radiation 141 of the upper end extension of main part 11 and bearing of trend and high-frequency radiation part 12, the end of this first Department of Radiation 141 upwards bends second Department of Radiation 142 that is extended with a bar shaped, the arc bending to the right of the end of this second Department of Radiation 142 also continues to the right that horizontal-extending has one first radiation arm, 1431, the first radiation arms, 1431 tip forward vertical extent that one second radiation arm 1432 is arranged.First radiation arm 1431 and second radiation arm 1432 are formed the 3rd Department of Radiation 143.

The end bending of described the 3rd Department of Radiation 143 is extended with the 4th Department of Radiation 144 of complications.The 4th Department of Radiation 144 has second radiation fin 1442 that first radiation fin 1441 that extends from the terminal bending downwards of second radiation arm 1432 and extends to form from first radiation fin, 1441 ends left.

See also Fig. 2, it is that the utility model antenna 100 is installed in the structural representation on the mobile phone (not shown).The cover top portion of mobile phone has a fixed leg 2 that roughly is the quadrangular shape, a left surface 23 and a right flank 24 that this fixed leg 2 has a front surface 21, a rear surface 22 and links to each other with rear surface 22 with front surface 21, described left surface 23 is relative with the position of right flank 24.The top of described front surface 21, rear surface 22, left surface 23 and right flank 24 is connected with an end face 25.Described antenna 100 is set on the fixed leg 2, and main part 11 is close on the front surface 21 of fixed leg 2, and high-frequency radiation part 12 is around front surface 21, rear surface 22 and right flank 24; The lower end of feeding portion 13 is connected with the circuit board (not shown).
