20090109114 | Antenna structure - An antenna structure includes a first tubing module, a second tubing module, an insulating tubing, a coaxial cable, an insulating tube and a base. Both ends of the insulating tubing are connected with the first and second tubing modules respectively. An interval is maintained between two corresponding ends connected with the tubing modules. The first tubing module is connected to the insulating tube, and the insulating tube is connected the base. The coaxial cable includes a central conductor and a metal conducting mesh, and the central conductor is connected the second tubing module, and the second tubing module is connected to a terminal inside the base. The metal conducting mesh is connected to the first tubing module, and the first tubing module is connected the base, so that the antenna structure can be operated at a specific frequency range and gives a better gain. | 04-30-2009 |
