Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, preferred embodiments of the present invention provides a kind of antenna structure 100, and it is applied in the radio communication device such as mobile phone, panel computer.This antenna structure 100 comprises feed side 10, the first radiant body 30, the second radiant body 50 and the 3rd radiant body 70.
Signal feed-in point (not shown) on the circuit board of this feed side 10 and radio communication device is electrically connected, and thinks this antenna structure 100 feed-in electric currents.
See also Fig. 2, this first radiant body 30 is connected on feed side 10, and it comprises the first shared segment 200, the second shared segment 202, the first extension 31, the second extension 33 and the 3rd extension 35 that connect successively.In the present embodiment, this first shared segment 200, the second shared segment 202, the first extension 31, the second extension 33 and the 3rd extension 35 are positioned at same plane.This first shared segment 200 is connected in a side of feed side 10, and extends towards the direction away from feed side 10.This second shared segment 202 is vertically connected between the first shared segment 200 and the first extension 31, and the first extension 31 extends towards the direction contrary with the bearing of trend of the first shared segment 200.This second extension 33 is vertically connected between the first extension 31 and the 3rd extension 35, and this second extension 33 and the second shared segment 202 be arranged in parallel, and extends towards the direction near the first shared segment 200.Meanwhile, between the second extension 33 and the second shared segment 202, form one first groove S1.The 3rd extension 35 and the first shared segment 200 be arranged in parallel, and extend towards the direction near feed side 10.Meanwhile, between the 3rd extension 35 and the first shared segment 200, form one second groove S2.In the present embodiment, the length of the length of this first shared segment 200 and the 3rd extension 35 is roughly suitable.In the design and manufacture stage, by adjusting the length of this first radiant body 30 and the size of the first groove S1 and the second groove S2, make this antenna structure 100 in the time that transmitting-receiving the first centre frequency is roughly the wireless signal (as GPS frequency range) of 1575MHz, there is preferably effect.
This second radiant body 50 comprises the first shared segment 200 and extension 51.This extension 51 is connected on feed side 10, and extend towards direction parallel with the second extension 33 this extension 51, and keeps certain spacing with the 3rd extension 35.In the design and manufacture stage, by adjusting the length of this extension 51, while making this first shared segment 200 and extension 51 resonate to receive and dispatch the wireless signal (as WLAN frequency range) that the second centre frequency is roughly 5230MHz, there is preferably effect.
The 3rd radiant body 70 comprises the first shared segment 200 and the second shared segment 202, electric current is flowed through the first shared segment 200 and the second shared segment 202 to excite a new mode from feed side 10, so that antenna structure 100 has preferably effect in the time that transmitting-receiving the 3rd centre frequency is roughly the wireless signal (as WLAN frequency range) of 2450MHz.
Further illustrate the operation principle of this antenna structure 100 below, first, when feed side 10 is from radio communication device feed-in electric current, electric current flows to respectively the first shared segment 200 and extension 51.On the first radiant body 30, electric current is flowed through the first shared segment 200, the second shared segment 202, the first extension 31, the second extension 33 and the 3rd extension 35 to inspire first mode, and then the wireless signal of transmitting-receiving the first centre frequency.Meanwhile, the flow through electric current on extension 51 and the current resonance of flowing through on the first shared segment 200 inspire the second resonance mode, and then the wireless signal of transmitting-receiving the second centre frequency.Finally, the electric current of flowing through on the first shared segment 200 and the second shared segment 202 inspires the 3rd mode, and then the wireless signal of transmitting-receiving the 3rd centre frequency.As shown in Figure 3, this antenna structure 100 is that 1575MHz, the second centre frequency have wider bandwidth and higher efficiency while being 5230MHz and the 3rd centre frequency wireless signal that is 2450MHz in transmitting-receiving the first centre frequency.
Antenna structure 100 of the present invention comprises multiple radiant bodies, and by the first shared segment 200 resonance mode new with extension 51 resonant excitations one, so that antenna structure 100 can be received and dispatched the wireless signal of multiple frequency ranges, increase the frequency range of antenna, simultaneously by rationally adjusting the length of extension 51, while making wireless signal that antenna structure 100 is 5230MHz in headend frequency, there is wider bandwidth.On the other hand, antenna structure 100 of the present invention is shared the first shared segment 200 by the first radiant body 30 and the second radiant body 50, the first radiant body 30 and the 3rd radiant body 70 are shared the first shared segment 200 and the second shared segment 202, contribute to reduce the size of antenna, be convenient to the miniaturization development of radio communication device.
Although the preferred embodiment of the present invention is illustrated and is described, the art personnel will realize, and can make different variations, and these do not exceed scope of the present invention.Therefore expect, the present invention is not limited to disclosed conduct and realizes the contemplated preferred forms of the present invention.
