Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figures 1 and 2, the built-in antenna of cell phone of present embodiment comprises antenna carrier (not shown) and antenna radiator.Described antenna radiator comprises antenna body and the distributing point 1 and the earth point 2 that are bent to form from antenna body downwards, distributing point 1 and earth point 2 respectively with the cell phone mainboard (not shown) on distributing point be connected with GND.
Described antenna body is a conductor branches, comprises the high-frequency radiation part 10 and the low frequency radiation portion 20 that are connected with each other.The initiating terminal of described high-frequency radiation part 10 and low frequency radiation portion 20 all links to each other with earth point 2 with distributing point 1.
Described high-frequency radiation part 10 is tabular, its initiating terminal links to each other with earth point 2 with distributing point 1, and its terminal is two isometric linearity branches 12,14 that are connected with each other, this two branches, 12,14 coplanes and being parallel to each other, and form a narrow slit 16 in the middle of these two branches 12,14.Like this, at the area that keeps to increase under the small and exquisite situation of antenna high-frequency radiation part 10, increase the responsive bandwidth of high-frequency radiation part 10.
The initiating terminal of described low frequency radiation portion 20 links to each other with the initiating terminal of distributing point 1 with earth point 2 and high-frequency radiation part 10, through becoming two branches 24,26 behind one section cabling 22.Described cabling 22 is roughly L-shaped, and its initiating terminal links to each other with high-frequency radiation part 10, and forms an acute angle, its terminal and high-frequency radiation part 10 coplanes with the interplanar at high-frequency radiation part 10 places.Described two branches 24,26 link to each other with the terminal of cabling 22, and one of them branch 24 and high-frequency radiation part 10 coplanes are circuitous bending, and form a L shaped narrow slit 27 in the middle of it.The initiating terminal of another branch 26 and high-frequency radiation part 10 coplanes, its terminal then with the interplanar shape at high-frequency radiation part 10 places in an angle, extend downward the below of high-frequency radiation part 10 by the plane inclination at high-frequency radiation part 10 places.The terminal of branch 26 is the narrow strip of type linearly, and is parallel with the initiating terminal of cabling 22, and and the initiating terminal of cabling 22 between form a narrow slit 28.
24 in the branch of described high-frequency radiation part 10 and low frequency radiation portion 20 forms a narrow slit 30.24 in the branch of cabling 22 and high-frequency radiation part 10 and low frequency radiation portion 20 forms a roughly L-shaped narrow slit 40.
