The antenna structure comprises a circuit board and an antenna unit, wherein the antenna unit is arranged on the circuit board, the circuit board is provided with a ground plane, the antenna unit comprises radiating bodies, the radiating bodies are uniformly arranged at the periphery of the ground plane at intervals in a surrounding way, an antenna is formed by sequentially connecting parts of radiating bodies in series, and the working frequency of the antenna can be adjusted through changing the number of the radiating bodies which are connected in series.
Description
Technical field
The present invention relates to a kind of antenna structure, relate in particular to a kind of antenna structure of adjustable operating frequency.
Background technology
Radio communication device is as being typically provided with antenna in mobile phone, and by this antenna transmission, receive radio wave transmitting, exchange radio data signal.In prior art, for reducing radio communication device manufacturing cost, and be conducive to the miniaturization of radio communication device, conventionally antenna printed to circuit board.But once antenna prints to circuit board, its operating frequency just cannot change.
Summary of the invention
For the problems referred to above, be necessary to provide a kind of antenna structure of adjustable operating frequency.
A kind of antenna structure, the antenna element that it comprises circuit board and is arranged at this circuit board, this circuit board is provided with ground plane, this antenna element comprises radiant body, the even compartment of terrain of this radiant body is located in the periphery of this ground plane, the partial radiation body formation antenna of connecting successively, the operating frequency of this antenna can regulate by changing the radiant body number that connect.
The number of the radiant body that antenna structure of the present invention can be connected by change regulates the length of antenna, thereby obtains different operating frequencies, to meet the different communication requirement of radio communication device.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the antenna structure 100 of preferred embodiment of the present invention can be used for radio communication device and carries out signal transmitting and receiving as mobile phone.This antenna structure 100 comprises circuit board 10 and is arranged at the antenna element 30 of this circuit board 10.
The mainboard that this circuit board 10 is mobile phone, roughly rectangular.This circuit board 10 is provided with the ground plane 11 of rectangular area.This ground plane 11 comprises two long limit 111 and two minor faces 113, and the end of this two long limit 111 and two minor faces 113 is connected to form four drift angles 115.
This antenna element 30 comprises some radiant bodies 31.Each radiant body 31 is roughly strip, and printing is formed on circuit board 10.This radiant body 31 successively evenly compartment of terrain be arranged in the periphery of ground plane 11.In this preferred embodiment, this radiant body 31 encloses formation rectangle frame, is arranged in respectively minor face 113 that 111 and 10, long limit radiant body 31 is arranged in respectively ground plane 11 specifically encloses and form by 24 radiant bodies 31.
This radiant body 31 encloses shape and also can adjust with the alteration of form of ground plane 11, thereby consistent with the periphery of ground plane 11.Wherein, partial radiation body 31 can be connected with adjacent radiant body 31 and be formed antenna by inductance or Zero-ohm resistor, and example is antenna 50,60 as shown in Figure 2, and by changing the number of the radiant body 31 of connecting, regulates the operating frequency of institute's formation antenna; Partial radiation body 31 can form isolation part by Zero-ohm resistor ground connection, and example is isolation part 70,80 as shown in Figure 2.
Refer to Fig. 2, in this preferred embodiment, these 3 radiant bodies 31 near long limit 111 that are positioned at two adjacent drift angles 115 are connected successively and form respectively antenna 50,60 with 1 radiant body 31 of close minor face 113, and this antenna 50,60 is respectively BT/WIFI antenna and gps antenna.Radiant body 31 numbers that series connection forms antenna 50,60 can increase or reduce to change its length, thereby obtain different operating frequencies.
Radiant body 31 between this antenna 50,60 is all connected to ground plane 11 ground connection by the resistance of zero ohm, forms isolation part 70,80, prevents from producing and disturbing between antenna 50,60.
The number of the radiant body 31 that antenna structure 100 of the present invention can be connected by change regulates the length of antenna 50,60, thereby obtain different operating frequencies, and the isolation part 70,80 forming between different antennae 50,60, prevent the interference between different antennae, guarantee the stable of antenna 50,60 performances.In addition, radiant body 31 printings are formed at circuit board 10 surfaces, make antenna structure 100 small volumes.
