ABSTRACT:
An antenna structure including a ground plate, a hollow bolt, and a conductive conical dome is provided. The hollow bolt passes through the ground plate, and a signal wire is laid in the hollow bolt. An insulator is disposed between the signal wire and the hollow bolt for providing electrical isolation therebetween. The conductive conical dome is connected with one end of the signal wire. The hollow bolt and a nut are provided to fix the antenna on a wall or a ceiling. Since the signal wire is laid in the hollow bolt, the signal wire can be connected to a signal source only by connecting a signal cable to the hollow bolt.
