[0025] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0026] It should be noted that when a component is referred to as being "connected" with another component, it can be directly connected with the other component or there can be intervening components. When a component is referred to as being "disposed on" another component, it can be directly disposed on the other component or there can be intervening components.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "may" and "can" include any one of, or all of, possible combination of the items listed in the respective clauses.

[0028] Reference Figure 1 In an embodiment of the present application, an antenna is disclosed, having opposite transmitting end and fixed end, the transmitting end containing an antenna body, having the function of transmitting signals, and the fixed end being used for fixing the transmitting end and serving as a connecting component when the antenna is installed.

[0029] The transmitting end includes the antenna body 3 and a shell 1 for containing the antenna body. The shell 1 has a hollow structure inside for placing the antenna body 3. One end of the shell 1 extends towards the fixed end to form a connecting rod 11 for connecting with the fixed end.

[0030] The fixed end includes a fixed seat 2, inside of which a sealable cavity 21 is formed for placing an antenna main board 4. The end of the connecting rod 11 is communicated to the cavity 21. The connecting rod 11 is also a hollow structure, constituting a circular tube for the wire (not shown in the figure) to pass through, for electrically connecting the antenna body 3 and the antenna main board 4.

[0031] Further, the connecting rod 11 and the fixed seat 2 are in a sealed state at the connection. For example, the connecting rod 11 and the fixed seat 2 are connected by screw threads, and sealing glue is applied at the connection.
