Abstract
The invention provides an antenna structure, including a main antenna and a parasitic antenna unit, wherein the parasitic antenna unit includes a bonding pad, and the bonding pad and the main antenna are coupled. In addition, the invention also provides a wireless communication device having the antenna structure. The abovementioned antenna structure uses the bonding pad as a radiator of the parasitic antenna unit, and can effectively improve antenna performance of the wireless communication device having a keyboard.
Description
Technical field
The present invention relates to a kind of antenna structure, particularly relate to a kind of antenna structure being applied to the radio communication device with keyboard.
Background technology
In a wireless communication device, be used for launching, receiving radio wave to transmit, to exchange the antenna assembly of radio data signal, one of most important assembly in radio communication device beyond doubt.
Although the smart mobile phone of touch-screen is subject to, major part is youthful to be liked, the mobile phone with keyboard is still subject to some business people, likes liking of colonies such as chatting on line.And for Antenna Design, the Antenna Design with the mobile phone of keyboard is challenging, because the existence of button makes the headroom district of antenna for mobile phone reduce, affect antenna performance.
Summary of the invention
In view of this, be necessary to provide a kind of being applied to have keyboard and the antenna structure with the radio communication device of superperformance.
Separately, be necessary to provide a kind of radio communication device with this antenna structure.
A kind of antenna structure, comprise main antenna and parasitic antenna element, described parasitic antenna element is the pad of the button of described radio communication device, is coupled between described pad with described main antenna.
A kind of radio communication device, comprise circuit board and antenna structure, this circuit board comprises load point, the first short dot and the second short dot, described antenna structure comprises main antenna and parasitic antenna element, described main antenna is between load point and the first short dot, and described parasitic antenna element is connected with the second short dot, and described parasitic antenna element comprises pad, described pad, as the radiant body of parasitic antenna element, is coupled between described pad with described main antenna.
Described antenna structure is using the radiant body of pad as parasitic antenna element, make pad as a part for the radiant body of antenna structure, avoid pad and be positioned at the headroom district of the antenna arranged separately to the impact of antenna performance product, thus improve the antenna performance of antenna structure.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the antenna structure of better embodiment of the present invention;
Fig. 2 is the antenna structure circuit module schematic diagram shown in Fig. 1.
Main element symbol description
Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 and Fig. 2, the antenna structure 100 of better embodiment of the present invention is applied to be had in the radio communication device 200 of keyboard.Described radio communication device 200 comprises circuit board 300.Described circuit board 300 comprises load point 301, first short dot 302, second short dot 303, headroom district 304 and keyboard scanning circuit 305.This load point 301 is for FD feed, and described first short dot 302 and the second short dot 303 are positioned at load point 301 both sides.In the present embodiment, antenna structure 100 is arranged at one end of circuit board 300.
Antenna structure 100 comprises main antenna 10 and parasitic antenna element 20.This main antenna 10 is electrically connected at load point 301 and the first short dot 302.In the present embodiment, this main antenna 10 works in multiple frequency range.
This parasitic antenna element 20 comprises pad 21, electric capacity C and inductance L.This electric capacity C is connected between the second short dot 303 and pad 21.This pad 21 is the pad 21 of the button of described radio communication device 200, and this pad 21 one end is connected to electric capacity C, and the other end is connected to inductance L.This inductance L is connected between pad 21 and keyboard scanning circuit 305.Described pad 21 is as the radiant body of this parasitic antenna element 20, and the quantity of this pad 21 can change as required, can think that one also can be multiple.When quantity between pad 21 is multiple, by being series between electric capacity C and inductance L at the cabling 306 of circuit board 300 between multiple pad 21.Shape and the length of adjustment cabling 306 can be passed through, to meet the needs of the antenna performance of antenna structure 100.This pad 21 comprises outer ring 211 and inner ring 213, makes outer ring 211 and inner ring 213 conducting, thus realize the operation of button by the pressing of button.In the present embodiment, the outer ring 211 of pad 21 as the radiant body of parasitic antenna element 20, that is, is electrically connected at together by cabling 306 between the outer ring 211 of multiple pad 21 mutually.The signal being low frequency and antenna due to keyboard signal is high frequency, thus the effect of electric capacity C be eliminate keyboard scanning circuit 305 low frequency signal on the impact of antenna structure 100, the effect of inductance L eliminates high-frequency signal to the impact of keyboard scanning circuit 305.
When described antenna structure 100 works, signal is fed into main antenna 10 from the load point 301 of circuit board 300, and described main antenna 10 is coupled with pad 21, to make this pad 21 as the radiant body of parasitic antenna element 20, improves antenna performance.
Inventive antenna structure 100 is using the radiant body of pad 21 as parasitic antenna element 20, make pad 21 as a part for the radiant body of antenna structure 100, avoid pad 21 and be positioned at the headroom district 304 of the antenna arranged separately to the impact of antenna performance product, thus improve the antenna performance of antenna structure 100.
