Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As Fig. 1～shown in Figure 3, the utility model is a kind of mobile phone duplex feeding antenna, comprises support 2, and support 2 is a cuboid, and the medium that adopts the ABS engineering plastics or have a similar dielectric constant is made.Radiating element 1 is installed on the support 2, radiating element 1 is a thin slice, be distributed in the top and the leading flank of cuboid support 2, radiating element 1 adopts antenna shrapnel material commonly used such as phosphor bronze, stainless steel or the contained metal material of FPC (Flexible PrintedCircuit, Flexible Printed Circuit) to make.Radiating element 1 is provided with a plurality of connecting holes, and support 2 is provided with and the corresponding a plurality of hot melt posts 4 of connecting hole.After radiating element 1 is attached to support 2 surfaces, by the hot melt post on the support 24 is melted to fix radiating element 1.
Have through hole 3 on the radiating element 1 of cuboid support 2 leading flanks, the periphery of through hole 3 forms the loop conductor.Radiating element 1 is divided into feed leg 5 and ground connection leg 6 above through hole 3, radiating element 1 links to each other with the radio circuit of mobile phone inside by the distributing point 7 on the feed leg 5, and radiating element 1 is by earth point 8 ground connection on the ground connection leg 6.
The top of support 2 can also be provided with groove, and feed leg 5 and ground connection leg 6 are positioned at groove.
Two sides are provided with buckle 9 about support 2, are used for and the engaging of handset shell.
The utility model is based on the monopole antenna basic principle, utilizes radiating element 1 to produce the wideband radiation of the 1710MHz～2170MHz of the wideband radiation of 824MHz～960MHz frequency range of lower frequency and upper frequency.The loop conductor that through hole 3 peripheries that are connected with distributing point 7 form, make between radiating element 1 and the feed element structure that constitutes duplex feeding, excitation radiation unit 1 produces required external electromagnetic field radiation well, realize rational impedance matching, the bandwidth that guarantees antenna is enough wide, excellent performance.The length of radiating element 1 can be used as the parameter of adjusting the low-and high-frequency center frequency points, spacing and the size that can come the regulation loop conductor according to required efficient and bandwidth.
The antenna that the utility model provides can effectively reach performance index, guarantees the signal stabilization of network, guarantees that the user is using mobile phone to converse or transfer of data is faster, operation reposefully, makes comfortable that the better enjoy network of user brings.
