Embodiment
By describing technology contents of the present invention, structural feature in detail, being realized purpose and effect, below exemplify specific embodiment and cooperate the graphic detailed explanation of giving.
See also Fig. 1, a kind of the utility model multifrequency antenna 1 make by metal material or on circuit board etching form, it comprises one first antenna part 10, a feeding portion 20, second antenna part 30 and a grounding parts 40.
First antenna part 10 has a strip parts 11, and this strip parts 11 has one first edge 111.One end at first edge 111, first edge 111 that is parallel to strip parts 11 after the suitable distance again that vertically stretches out extends to form first a L-shaped Department of Radiation 12, the part that is parallel to first edge 111 of this first Department of Radiation 12 and strip parts 11 are repeatedly put reducing the volume of this multifrequency antenna 1, and the end of first Department of Radiation 12 is defined as first open end 121.The other end at first edge 111 of strip parts 11 vertically stretches out and forms second Department of Radiation 13 of a strip.
Feeding portion 20 forms for vicinity second Department of Radiation 13 places by first edge 111 stretch out.The end of feeding portion 20 is provided with a load point 21, and this end roughly extends second antenna part 30 that is strip that is parallel to first edge 111 of strip parts 11 towards first open end 121 of first Department of Radiation 12, these second antenna part, 30 ends are defined as second open end 31, this second open end 31 produces coupling effect to increase the electrical length of second antenna part 30 and first Department of Radiation 11 thus near first open end 121.
Grounding parts 40 is stretched out by first edge 111 at contiguous feeding portion 20 places and forms, and its end is provided with an earth point 41.Grounding parts 40 has two and is parallel to the extension 42,43 of second Department of Radiation 13 and is connected kink 44 between two extensions, this kink 44 roughly is " U " shape and its opening towards feeding portion 20, thereby makes grounding parts 40 be bending with as an inductance in parallel.
When the utility model multifrequency antenna 1 was used for wireless telecommunications, electric current was by this multifrequency antenna 1 of load point 21 feed-ins.When electric current flow to first open end 121 of first Department of Radiation 12 by feeding portion 20, strip parts 11, because the route that electric current is flowed through is longer, but multifrequency antenna 1 resonance went out the low frequency signal in 850MHz to the 900MHz frequency band range; When electric current by feeding portion 20, when strip parts 11 flow to second Department of Radiation 13 because the electric current route of flowing through is shorter, but this multifrequency antenna 1 resonance goes out the high-frequency signal in 1710MHz to the 2170MHz frequency band range, and the frequency of this signal is close to 1710MHz; And when electric current flow to second open end 31 of second antenna part 30 by load point 21, but this multifrequency antenna 1 resonance goes out the high-frequency signal in 1710MHz to the 2170MHz frequency band range, and the frequency of this signal is near 2170MHz.
See also Fig. 2, when the multifrequency antenna 1 of above-mentioned the utility model works in 0.824GHz (as number in the figure 1), 0.960GHz (as number in the figure 2), 1.710GHz (as number in the figure 3) and 2.170GHz (as number in the figure 4) respectively, its voltage standing wave ratio is respectively 3.0189,3.1048,1.4330,2.9882, the multifrequency antenna 1 of the utility model meet voltage standing wave ratio less than or approach 3 requirement.
As mentioned above, design by first antenna part 10 and second antenna part 30, make when the utility model multifrequency antenna 1 is used for wireless telecommunications, can receive and dispatch the low band signal that is in GSM850, EGSM900 and the high-frequency band signals of DSC1800, PSC1900 and W-CDMA2100.Simultaneously, the same side that first Department of Radiation 12 of first antenna part 10 and second Department of Radiation 13 and second antenna part 30 are located at the strip parts 11 of first antenna part 10 can reduce the volume of this multifrequency antenna 1, thereby makes the utility model multifrequency antenna 1 easier being installed in the small-size hand-hold electronic product.
