Beneficial effect of the present invention:
Compared with prior art, a kind of dual-band antenna receiving and dispatching WiFi and gps signal provided by the present invention, adopt the structural design of the first groove, the second groove (and the 3rd groove), by the impedance of the zigzag part of the first groove and the width-adjustable antenna of the second groove, on second metal level of second surface and first surface by the second groove and the 3rd groove around the first metal layer intercouple, therefore without the need to by other switch, the communication function of WiFi and GPS two-band can be realized.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation receiving and dispatching the dual-band antenna preferred embodiment of WiFi and gps signal of the present invention.
Fig. 2 A and Fig. 2 B is a kind of first surface and second surface structural representation receiving and dispatching the dual-band antenna preferred embodiment of WiFi and gps signal of the present invention.
Embodiment
The invention provides a kind of dual-band antenna receiving and dispatching WiFi and gps signal, for making object of the present invention, technical scheme and effect clearly, clearly, referring to accompanying drawing examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of dual-band antenna preferred embodiment of receiving and dispatching WiFi and gps signal provided by the present invention, as shown in Figure 1, Figure 2 shown in A and Fig. 2 B, the described dual-band antenna receiving and dispatching WiFi and gps signal, it comprises: substrate 1, the first metal layer 10 and the second metal level 14.Substrate 1 has relative first surface 1a and second surface 1b, and the first metal layer 10 is arranged on first surface 1a and covers first surface 1a, and the second metal level 14 is arranged on second surface 1b and local complexity second surface 1b.Wherein, the first metal layer 10 is for ground connection, and the second metal level 14 is then the coupling for antenna.
As shown in Figure 2 A, the described WiFi of transmitting-receiving also comprises with the dual-band antenna of gps signal: be arranged on first surface 1a and be provided with a zigzag part 110 as in the middle part of the first groove 11 of exposed parts and the second groove 12, first groove 11 of being connected with described first groove 11.In addition, the end of the first groove 11 is also provided with the first extension 11a vertical with the first groove 11, and is provided with feeding portion 15, for the feed-in signal of telecommunication on the first surface 1a of the first extension 11a.The end of the second groove 12 is provided with the second extension 12a, and the second extension 12a is vertical with the second groove 12, and is provided with at least one perforation 16 running through first surface 1a and second surface 1b on the substrate 1 of the second extension 12a.
