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 notebook computer 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, feed element 3 and ground unit 4 are installed on the 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 Printed Circuit, Flexible Printed Circuit) to make, and links to each other by the radio circuit of feed element 3 with notebook computer inside.Radiating element 1 is provided with a plurality of connecting holes 11, and cuboid support 2 is provided with and connecting hole 11 corresponding a plurality of hot melt posts 8.After radiating element 1 is attached to support 2 surfaces, by the hot melt post on the support 28 is melted to fix radiating element 1.Feed element 3 is a coaxial cable, and its inner core links to each other with radiating element 1, its outer ground connection.Ground unit 4 is the conduction foil paper.
Radiating element 1 in the utility model is a thin slice, is distributed in the top and the leading flank of cuboid support 2.The radiating element 1 of cuboid support 2 leading flanks is a strip, and the one end has through hole 9, and the periphery of through hole 9 forms the loop conductor, and the distributing point 5 of feed element 3 is positioned at the below of through hole 9.Ground unit 4 is positioned at the bottom of cuboid support 2, links to each other with the other end of the strip radiating element 1 that is positioned at cuboid support 2 leading flanks.
The radiating element 1 at cuboid support 2 tops comprises first long radiation arm 7 and the second short radiation arm 10.The open end of first radiation arm 7 and second radiation arm 10 is provided with the extension that is positioned on support 2 leading flanks.The effect of extension is to guarantee that the bandwidth of antenna is enough wide.
The radiating element 1 of cuboid support 2 leading flanks extends to form strip brace 6 to the bottom of cuboid support 2, and brace 6 links to each other with ground unit 4.By brace 6, radiating element 1 is connected reliably with ground unit 4.
