Existing a kind of multifrequency antenna has a junction, one side of connecting portion is extended the elongated bonding jumper of a L-shaped bending, comes the simulaed inductance assembly to adjust the resonance frequency and the impedance matching of multifrequency antenna by the minor face ground connection of " L " shape bonding jumper and long limit are parallel to the ground.The opposite side of connecting portion extends the Department of Radiation that several are set up in parallel perpendicular to connecting portion.Yet because the L-shaped bending of bonding jumper of simulaed inductance assembly, and be positioned at the both sides of connecting portion respectively with the Department of Radiation of multifrequency antenna, this can make multifrequency antenna integral body take bigger space.
The utility model content
The purpose of this utility model is to provide a kind of little multifrequency antenna that takes up room at defective and deficiency that prior art exists.
For achieving the above object, the utility model provides a kind of multifrequency antenna, comprises a junction, and a grounding parts arranged side by side and a feeding portion are extended in the middle part of connecting portion one lateral margin, and grounding parts is provided with earth point, and feeding portion is provided with load point; The last lateral margin of feeding portion end extends one first Department of Radiation; Another lateral margin of connecting portion extends one second Department of Radiation.
As mentioned above, the grounding parts of the utility model multifrequency antenna and feeding portion are set up in parallel and can form the simulation shunt inductance that takes up room little, therefore it is little multifrequency antenna integral body to be taken up room, thereby adapted to the compact day by day development trend of portable type electronic product, and first Department of Radiation can be received and dispatched the electromagnetic wave signal of PCS1900～WCDMA2100 communication system, second Department of Radiation can be received and dispatched the electromagnetic wave signal of GSM850 communication system, satisfies portable type electronic product needs transmitting-receiving multiband, wide band electromagnetic demand.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1, the utility model multifrequency antenna 1 adopts the Copper Foil etching on the flexible PCB to form.This multifrequency antenna 1 has the connecting portion 10 of a rectangular plate shape.The middle part of connecting portion 10 1 lateral margins locates to vertically extend a tabular grounding parts 20 on the lower side, and the end of grounding parts 20 is provided with earth point 21.The middle part of connecting portion 10 1 lateral margins locates to vertically extend a tabular feeding portion 30 on the upper side, and the end of feeding portion 30 is provided with load point 31.Feeding portion 30 be set up in parallel with grounding parts 20 and the lower lip of feeding portion 30 parallel with the last lateral margin of grounding parts 20, thereby between grounding parts 20 and feeding portion 30, form a groove 40.
The last lateral margin of feeding portion 30 ends extends upward one first Department of Radiation 50.First Department of Radiation 50 has the first radiation connecting portion 51 of the long strip-board shape that directly extends upward from the upside marginal lappet of feeding portion 30 ends, the margo dexter of the first radiation connecting portion, 51 ends extends 52, the first radiation ends 52, one first radiation end perpendicular to the first radiation connecting portion 51 and is parallel to feeding portion 30.
Another lateral margin of connecting portion 10 extends one second Department of Radiation 60.Second Department of Radiation 60 has the second radiation connecting portion 61 parallel with the first radiation connecting portion 51 that outwards extends out vertically upward again from another lateral margin of connecting portion 10, the length of the second radiation connecting portion 61 is greater than the length of the first radiation connecting portion 51, and the left border of the second radiation connecting portion 61 stretches out and forms first extension 611.The end of the second radiation connecting portion 61 is extended with kink 62 towards the vertical bending of a side at the first radiation connecting portion, 51 places, and the end of kink 62 side towards connecting portion 10 places again vertically extends the 3rd radiation connecting portion 63.The outside respectively vertical extent in the upper end of the margo dexter of the 3rd radiation connecting portion 63 and lower end is formed with second extension 631 and the 3rd extension 632.The junction of the 3rd extension 632 and the 3rd radiation connecting portion 63 offers the last lateral margin of the lower lip of a fluting 633, the three extensions 632 near the first radiation end 52.
When the utility model multifrequency antenna 1 is used for communication, be set up in parallel and an end can form a simulation shunt inductance by grounding parts 20 and the feeding portions 30 that connecting portion 10 links to each other, this simulation shunt inductance can reach the effect of simulation shunt inductance assembly, thereby this multifrequency antenna 1 can reach impedance matching with high-frequency circuit.During first Department of Radiation, 50 transmitting-receiving frequency electromagnetic waves, simulation shunt inductance acting in conjunction with grounding parts 20 and feeding portion 30 formation, can increase the bandwidth of first Department of Radiation 50, making the Department of Radiation 50 of winning can be the electromagnetic wave signal that the electromagnetic wave resonance of 1900MHz～2100MHz frequency range is received and dispatched DCS1900～WCDMA2100 communication system with frequency.
In sum, the grounding parts 20 of the utility model multifrequency antenna 1 and feeding portion 30 can form the little simulation shunt inductance of occupation space, therefore can make multifrequency antenna 1 integral body take up room little, thereby adapted to the compact day by day development trend of portable type electronic product, and first Department of Radiation can be received and dispatched the electromagnetic wave signal of PCS1900～WCDMA2100 communication system, second Department of Radiation can be received and dispatched the electromagnetic wave signal of GSM850 communication system, satisfies portable type electronic product needs transmitting-receiving multiband, wide band electromagnetic demand.
