Specific embodiment
Referring to Fig. 1, better embodiment of the invention provides a kind of wireless communication device 100, can for mobile phone,
The mancarried devices such as personal digital assistant.
The wireless communication device 100 includes substrate 10, shell 30 and current fed portion 50.
In the present embodiment, which is the circuit board of wireless communication device 100, uses epoxy resin fiberglass
(FR4) it is made.One load point 12 and a ground plane (figure is not marked) are set on the substrate 10.The load point 12 is used to provide electric current,
The ground plane is for providing system earth.
Fig. 2 and Fig. 3 is please referred to, which is made of metal comprising a bottom plate 32 and two side plates 34, two side
Plate 34 is oppositely arranged and is connected to the two sides of bottom plate 32.The bottom plate 32 and two side plates 34 surround an accommodating space (not shown),
To accommodate substrate 10 and current fed portion 50.
For the bottom plate 32 for the antenna radiator as wireless communication device 100, one end of the bottom plate 32 opens up one first
Groove 322, a second groove 324 and a link slot 326.The first groove 322 is a straight groove comprising opposite two
Side 3222,3224.The second groove 324 is a straight groove, is connected to first groove 322, the second groove 324 packet
Include opposite dual side-edge 3242,3244.In the present embodiment, the length of the first groove 322 is longer than second groove 324, width
It is wider than second groove 324, and the side 3222 of the first groove 322 and the side 3242 of second groove 324 exist always positioned at same
Line, the side 3224 of first groove 322 are staggered with the side 3244 of second groove 324.One end of the link slot 326 is connected to
The junction of one groove 322 and second groove 324, and be connected to first groove 322 and second groove 324.The link slot 326
Including two opposite short sides 3262,3264, the short side 3262 of the link slot 326 and side 3224 of first groove 322 is vertical connects
It connects, the short side 3264 of the link slot 326 and side 3244 of second groove 324 is vertical connect.In the present embodiment, first ditch
The width of slot 322 is about 1.5mm, and the width of the second groove 324 is about 1mm, and the width of the link slot 326 is about 0.5mm.It is logical
The link slot 326 connection first groove 322 and second groove 324 are crossed, so that bottom plate 32 forms open type antenna, is adjusted convenient for passing through
The size of the whole link slot 326 reduces the length of first groove 322 and second groove 324.
On the bottom plate 32 first groove 322, second groove 324 and connection further can be blocked by modes such as leather sprayings
Slot 326, in order to avoid influence the appearance of wireless communication device 100.
Two side plate 34 is electrically connected with the ground plane of substrate 10, so that electric current is through bottom plate 32, side plate 34 and substrate 10
Form current loop.
The current fed portion 50 is set to the top of bottom plate 32, and keeps certain spacing (about 0.4mm) with bottom plate 32, with
It is coupled with bottom plate 32 and collectively as the antenna of the wireless communication device 100.In the present embodiment, which is one
The substantially microstrip line of " L " type comprising the first feed-in section 52 and the second feed-in section 54.One end of the first feed-in section 52 and base
Load point 12 on plate 10 is electrically connected, to obtain electric current.The first feed-in section 52 is straightly across first groove 322 close to
One end of two grooves 324, which is vertically connected at the other end of the first feed-in section 52, and crosses link slot 326.
The working principle of the wireless communication device 100 is further illustrated below, portion 50 current fed first is from load point 12
After obtaining electric current, coupled with bottom plate 32, so that the first groove 322, second groove 324 and link slot 326 on bottom plate 32 are felt
Electric current should be arrived.Thereafter, electric current returns to the ground plane of substrate 10 by side plate 34, and then forms current loop.Due to first groove
322 and 324 surrounding current strength of second groove it is larger so that the bottom plate 32 inspires the first mode of resonance by first groove 322
State to receive and dispatch the wireless signal with the first centre frequency, and inspires the second resonance mode by second groove 324, to receive
Send out the wireless signal with second central frequency.Fig. 4 is please referred to, by the size for adjusting the first groove 322, so that should
Wireless communication device 100 has preferable when receiving and dispatching wireless signal (such as GPS) that the first centre frequency is 1570-1575MHz
Efficiency.Meanwhile by the size for adjusting the second groove 324, so that the wireless communication device 100 is in transmitting-receiving second central frequency
For 2400-2484MHz wireless signal (such as WIFI) when have preferable efficiency.
Wireless communication device 100 of the invention opens up first groove 322 and second on the shell 30 made of in metal
Groove 324, so that the bottom plate 32 of the shell 30 is received and dispatched with the first centre frequency as antenna radiator and has the second center
The wireless signal of frequency.The wireless communication device 100 efficiently solves tradition as antenna using shell 30 made of metal
Antenna Design avoids the problem of metal shell, and improves antenna transmitting-receiving efficiency, and be conducive to the miniaturization of wireless communication device 100
Development.
