Description

Technical Field

[0001] The utility model relates to the technical field of antennas, and particularly to a practical multi-frequency combined fiberglass antenna.

Background Art

[0002] An antenna is actually a converter. Its basic working principle is to convert the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) (for transmitting signals), or to convert the electromagnetic wave into a guided wave (for receiving signals).

[0003] With the rapid development of wireless communication technologies, such as 5G mobile communication, vehicle-mounted communication, WIFI and Bluetooth, there are more and more types of antennas. However, to maintain a long lifespan, corrosion resistance and high stability of antennas outdoors, fiberglass antennas need to be used because fiberglass has characteristics such as corrosion resistance, hardness and firmness.

[0004] The bandwidths of existing fiberglass antennas are relatively narrow and the frequencies are relatively fixed, so the same antenna cannot be adapted to multiple devices. Moreover, the fixing method is not firm, and the installed antenna is prone to looseness after a long time, affecting the transmission rate and signal strength.
