Description

Anticorrosion glue stick antenna Technical Field The application relates to the technical field of wireless communication, in particular to an anti-corrosion rubber rod antenna. Background Wireless communication is a communication method for exchanging information by utilizing the characteristic that electromagnetic wave signals can propagate in free space, and in the field of information communication in recent years, the most rapidly developed and most widely applied wireless communication technology is the wireless communication technology. Wireless communication implemented in mobile is also known as mobile communication, and both are commonly referred to as wireless mobile communication. An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa, and is generally reversible. The components used for transmitting or receiving electromagnetic waves in radio equipment, such as engineering systems of radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like, are operated by virtue of antennas whenever the electromagnetic waves are utilized for transmitting information. In addition, in terms of energy transfer with electromagnetic waves, an antenna is also required for energy radiation other than signals. The antenna forms are two main types, namely an internal antenna and an external antenna, wherein common internal antennas comprise Monopole antennas, PIFA antennas, patch ceramic antennas, FPC antennas and the like, and common external antennas comprise rod antennas, telescopic antennas, spiral antennas, vehicle-mounted antennas and the like. In order to solve the defects of the prior art lacking the protection mechanism, the dust cover, the support rod and other parts can drive the support rod to rotate, so that the sacrificial block is contacted with the joint, and the sacrificial block can be corroded in preference to the joint by utilizing the electrochemical principle of a sacrificial anode, thereby achieving the anti-corrosion effect on the joint.
