Second branch 533 is substantially L-shaped, including the first resonance paragraph 539 and the second resonance paragraph 540.One end of first resonance paragraph 539 is vertically connected to the tie point of the extension 536 of the second linkage section 535 and first, and extends along parallel first linkage section 534 and close to the direction of the radiant body 51.The generally rectangular shaped strip of second resonance paragraph 540, its one end is vertically connected to end of first resonance paragraph 539 away from the extension 536 of the second linkage section 535 and first, the other end extends along vertical first resonance paragraph 539 and close to the direction of second extension 537, and then collectively forms the L-type structure with first resonance paragraph 539.
It is appreciated that current signal can be respectively fed into the radiant body 51 and stub antenna 53 by the load point 617 of the first load point 615 and second.Specifically, when the current signal enters fashionable from second load point 617, one part of current will pass through the connecting portion 531, and flow through first branch 532, and then cause the stub antenna 13 to be operable with 2.4GHz frequency ranges.Another part electric current then passes through the connecting portion 531, and flows through second branch 533, and then causes the stub antenna 13 to be operable with 5GHz frequency ranges.In addition, current signal enters the radiant body 51 by first load point 615, and then cause the radiant body to receive and dispatch gps signal, that is, reach GPS/WIFI multiband design.
Obviously, the antenna structure 500 is set after the stub antenna 53, the earth current direction of the antenna structure 500 can effectively be changed, and then change its polarised direction, finally improve the episphere radiation pattern of the antenna structure 500, so that the emittance of the antenna structure 500 is concentrated mainly on episphere field pattern, to be effectively improved the performance that the antenna structure 500 receives satellite-signal.
Embodiment of above is merely illustrative of the technical solution of the present invention and unrestricted, although the present invention is described in detail with reference to above better embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent substitution should not all depart from the spirit and scope of technical solution of the present invention.Those skilled in the art can also do the design that other changes etc. are used in the present invention in spirit of the invention, without departing from the technique effect of the present invention.These changes done according to present invention spirit, should all be included within scope of the present invention.
