When after having laid metal parts near the antenna, metal parts can produce capacitive reactances to antenna, this capacitive reactances can cause the impedance mismatching of the RF circuit on antenna and the cell phone mainboard, thereby cause antenna efficiency to reduce, inductance in parallel between the RF of cell phone mainboard signal feed point and direct current ground can be eliminated described capacitive reactances, lays the influence of metal parts to antenna efficiency thereby eliminate near antenna.Our experiments show that when the high-frequency resonant frequency is 1800MHz, when the low-frequency resonant frequency was 900MHz, the optimum value of inductance in parallel was 4.2nH.
Because antenna body is attached on a plurality of of antenna holder, and the cabling form of antenna body and the inductance that connects between the RF of cell phone mainboard signal feed point and direct current ground make can place metal parts near antenna bodies, wherein, described RF signal feed point links to each other with the distributing point 13 of antenna, the distance of the minimum of described metal parts and antenna body can be 3mm, therefore, the volume of antenna holder can be done very for a short time, particularly, the length of antenna holder from its left side to its right side can be 40mm, width from its front to its back is the wideest to be 20.8mm, the narrowest is 6.7mm, and face can be 6.85mm to the height minimum below it from it.The height minimum of antenna holder from top to following has only 6.85mm, this for design a relatively thin mobile phone provide may, and the overall volume of antenna holder is also less, thus for design a not only thin but little mobile phone provide may.
Antenna described in the foregoing description, antenna body in other words, the material that is adopted all is flexible circuit board (Flexible Printed Circuit, FPC) so that with antenna in other words antenna body stick on antenna holder.
Below, low-and high-frequency resonance frequency and bandwidth that how three slits in the foregoing description and two radiant bodies and distributing point are adjusted antenna further specify:
(1) can adjust high frequency frequency resonant point and high frequency bandwidth, can adjust low frequency frequency resonant point and low frequency bandwidth by length and the width of adjusting first radiant body 11 by the length of adjusting second radiant body 12, length and width by adjusting first slit 14, second slit 15, the 3rd slit 16 and be connected the RF signal feed point of cell phone mainboard and the inductance value between the direct current ground can be adjusted the radiation efficiency of antenna.Wherein, the 5th section radiating surface 125 of second radiant body and first radiant body 11 are by 15 couplings of second slit, and the length and the width of second slit 15 and the 3rd slit 16 are bigger to the influence of the radiation efficiency of antenna.
(2) for the adjustment of the length of second radiant body 12, can realize by adjusting the length that second radiant body 12 is parallel to first radiant body part on two limits about in the of 11, also can realize by the length of adjusting lengthening radiating surface 126.
After utilizing an above-mentioned distributing point, two radiant bodies, three slits and inductance value that high-frequency resonant frequency, low-frequency resonant frequency, high frequency bandwidth, low frequency bandwidth and the radiation efficiency of antenna are adjusted, the return loss plot of built-in one pole dual-band mobile phone antenna is to be example with low frequency frequency range about 900MHz and the high-frequency band about 1800MHz among Fig. 4 as shown in Figure 4 in the utility model.
As seen, in antenna of the present utility model and the antenna modules, because the top of second radiant body is narrow away from other parts of the second radiant body free end proportion by subtraction, second radiant body, with far away again away from the distance of the second radiant body free end portion to bigger first slit of the radiation efficiency of antenna influence and second slit and described top, therefore radiation efficiency is lower, when near this part, placing metal parts, the capacitance characteristic that antenna has been produced owing to placed metal parts can be eliminated by inductance in parallel between distributing point and antenna mainboard, therefore, it is less to the integral radiation effectiveness affects of antenna to place metal parts on described top near away from the part of the second radiant body free end portion, thereby can reduce the actual occupation space of Monopole antenna when keeping antenna efficiency.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection range of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
