The application of intelligent watch gets more and more, and bluetooth and WIFI antenna are requisite parts in intelligent watch.For a user, ultra-thin and metal shell intelligent watch is more vulnerable to be liked.But, metal shell would generally weaken antenna performance, and therefore reaching the high-performance of antenna for hope is very big challenge.Additionally, the size of traditional ceramic paster antenna and weight are all very big, not therefore being suitable for watch device, and adopt traditional antenna form to complete, overall efficiency is also undesirable.
Summary of the invention:
For this, it is an object of the invention to propose a kind of size and weight is little, overall efficiency is good all-metal intelligent watch antenna.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of all-metal wrist-watch antenna, including table body, described table body is made up of metab, the pcb board being fixedly mounted in metab and the display screen that is arranged on described pcb board, described metab has been additionally provided with a radiant body and one coupling ground, described radiant body, coupling ground and metab three between be not in contact with each other.
Preferably, described metab is one-body molded by metal bottom cover and the metal edge frame that is arranged in this metal bottom cover.
Preferably, it is arranged on pcb board to described coupling.
Described radiant body is made up of vertical member and the horizontal element being connected with described vertical member, and described horizontal element is arranged on described pcb board.
Gap L 1 it is formed with between described vertical member and metal edge frame；Described horizontal element is formed with gap L 2 with coupling between ground.
Compared with prior art, the present invention utilizes the radiant body of all-metal frame and antenna to couple, and takes full advantage of metal edge frame, it is achieved thereby that the purpose of good radiation and good directivity.

Detailed description of the invention:
For setting forth thought and the purpose of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1 and Figure 2, Fig. 1 is the schematic perspective view of intelligent watch table body of the present invention；Fig. 2 is the structural representation of watch body of the present invention.Described in the present embodiment is the intelligent watch of a kind of all-metal watchcase, and it includes table body 10, and described table body 10 is made up of metab 11, the pcb board 13 being fixedly mounted in metab 11 and the display screen 12 that is arranged on described pcb board 13.
Wherein metab 11 is one-body molded by metal bottom cover 111 and the metal edge frame 112 that is arranged in this metal bottom cover 111.
As shown in Figure 3, Figure 4, Fig. 3 is the close-up schematic view of A in Fig. 2；Fig. 4 is the structural representation of radiant body in Fig. 3.Also including a coupling ground 131 and a radiant body 14 in metab 11, wherein coupling ground 131 is arranged on described pcb board 13, coupling ground 131 while pcb board 13 makes can respective production on pcb board 13.
Wherein radiant body 14 is made up of vertical member 141 and the horizontal element 142 being connected with described vertical member 141, and described horizontal element 142 is arranged on described pcb board 13.
As shown in Figure 5, Figure 6, Fig. 5 is the top view of all-metal wrist-watch antenna of the present invention；Fig. 6 is the close-up schematic view of B in Fig. 5.
As can be seen from Figure, radiant body 14, coupling ground 131 and metal edge frame 112 three between be not in contact with each other.Coupling ground 131 is arranged on pcb board 13；It is formed with gap L 1 between vertical member 141 and the metal edge frame 112 of radiant body 14；Described horizontal element 142 is formed with gap L 2 with coupling between ground 131.
In certain embodiments, horizontal element 142 with the gap L 2 coupled between ground 131 apart from for 0.01mm；Distance between coupling ground 131 and display screen 12 is 2.5mm；Gap L 1 between vertical member 141 and metal edge frame 112 is apart from for 0.4mm.
The present invention takes full advantage of metal edge frame, it is achieved that aerial signal carries out the coupling feeding and passing through and couple ground and becket etc. thus producing resonance from PCB to radiant body, it is achieved thereby that good radiation and good directivity.
Fig. 7 is the impedance operator schematic diagram of all-metal wrist-watch antenna of the present invention.It is respectively less than-10dB in 2.4GHz-2.5GHz overall impedance characteristic in terms of data.
Fig. 8 cancels bottom and cancels the impedance operator contrast schematic diagram of bottom and metal edge frame.The impedance operator situation of contrast removal metal bottom cover and removal metal bottom cover add the impedance operator situation of metal edge frame respectively, in terms of impedance operator, the impact of antenna performance is very big by metal edge frame and metal bottom cover, and antenna mainly sees that antenna radiator and ground couple the favourable radiation of generation with becket and metal bottom cover.
Fig. 9 is original impedance characteristic and the impedance operator contrast schematic diagram removably coupled.As viewed from data are unicast except the impedance operator behind coupling ground, it is impossible to reach below-10dB, serve to coupling the effect producing double wave expansion bandwidth.
Figure 10～12 are that inventive antenna is respectively at the typical 3D antenna pattern at 2.4GHz, 2.45GHz, 2.5GHz place, can be seen that from described directional diagram, the present invention reaches 6dBi at the directivity factor of screen side while can reaching good radiation, it is possible to present good directivity.
