Dipole antenna

Abstract

The invention discloses a dipole antenna, which comprises a connector, a metal pole, a wire, a coil, a sheath and a metal tube which is embedded on the connector in a matching way. The wire comprises a signal wire and a shielding wire, wherein the shielding wire of the wire penetrates through the metal tube and is connected with the metal tube, the axial center of one end of the metal pole is provided with a stepping surface, the axial center of the stepping surface is provided with a first through hole, the signal wire of the wire is welded in the through hole, the axial center of the other end of the metal pole is provided with a second through hole, and the coil is riveted in the second through hole of the metal pole; and the coil, the metal pole, the metal tube and the wire are sleeved in the sheath, the sheath is fixedly connected with the connector, and a fixing plug is arranged between the coil and the sheath. The dipole antenna has the advantages that the frequency and signal of transmission are stable, and the product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dipole antenna. Background technique [0002] In the technical field of wireless communication, a wireless communication device needs to send or receive signals through an antenna. For example: wireless routers, used to transmit signals of wireless communication devices. A dipole antenna in the prior art generally includes a connector, a copper pipe, a copper post, a wire, a coil, and a sheath. Wherein, the connector includes a signal end and a ground end; the signal end may be a pin or a hole. That is, the connector can be either male or female. The wire includes a signal wire and a ground wire. The signal wire is connected to the copper column and the signal end of the connector for signal transmission; the ground wire is connected to the copper tube and the ground end of the connector for shielding interference signals. The signal line of the coil and the ...

AI Technical Summary

Problems solved by technology

The signal line of the coil and the wire is connected through a copper column, and the coil and the copper column are generally riveted, and the signal line of the wire and the copper column are generally welded; the dipole antenna with this structure, because the copper column is a hollow through hole, The signal line of the wire is welded in the center hole of the copper column. Since the solder is connected to the center hole of the wire and the copper column, it is difficult to weld, and it is prone to false welding and false welding, which affects the dipole. The stability of the transmitting frequency of the antenna even reduces the quality of the dipole antenna

In addition, in the dipole antenna of the prior art, the coil is sleeved in the sheath to protect the coil from damage and collision, but there is a gap between the top of the coil and the sheath. direction, due to the action of force, the coil will shake in the sheath. During the shaking of the coil, the frequency of the signal transmitted by the antenna is unstable, which not only affects the transmission frequency of the wireless communication device using this dipole antenna, but also affects the The stability of the signal received by the receiving device
